Thought I’d share these for anyone who hasn’t seen them :) They’re the official descriptions for each of the Anemoi albums on The Oh Hellos’ website!
Notos
Notos, the first installment in an ongoing series, is named for the ancient Greco-Roman god of the south wind, who brought storms in the summer. Musically, the record draws from the siblings' memories of summers spent exploring the Pacific Northwest with their grandparents, as well as their experiences with the frequent threat of hurricanes as they grew up on the Texas Gulf Coast. Thematically, the series considers the question: "where did our ideas come from?" Notos recounts a time when the duo weren't even aware there was a question to ask, and reflects on the backfire effect we experience when confronted with new information for the first time.
Eurus
Once that first question posed in the Notos EP is asked — "where did my ideas come from?" — it opens the floodgates to more. While wrestling with them all can ultimately lead to a fuller understanding of the world around you (and leave you with more empathy than you started with), it can also leave you feeling alienated from the communities you used to identify with. Eurus, released in early 2018 as the second installment in a series, is a continued interrogation of our own beliefs, and as Eurus was the wind most closely associated with autumn, the record seeks to capture the feelings of dark woods, dry branches, dead leaves, and wondering who had migrated — you, or your flock?
Boreas
Boreas, the northern wind, ushered in the harsh frosts of lonely winter. The arrangements of this third installment evoke images of snow-blanketed darkness, candlelight behind cupped hands, and a vast night sky ribboned with stars and auroras. As we wrote these songs, we found ourselves confronted with the ways we’ve personally and communally reflected the character of this wind — how we often avoid discomfort, even at the expense of others, until we are left cold, hard, and unfeeling. In this record, we ask the winter to instead kindle us into something warmer and softer than who we’ve been.
Zephyrus
The series concludes. Zephyrus, the final cardinal wind of this project, brought the gentle warmth of spring that summoned up a new year of growth rooted in the fertile ashes of all the structures that keep us isolated and unfeeling — the kind of growth we can see in ourselves, if we can muster the courage to be vulnerable. The arrangements mirror and embrace this shift, rising up like tender leaves breaking through concrete and cascading down like mountain rivers surging with the first thaw of the season. It’s been a long year; thanks for listening.

The American woodcock (Scolopax minor), sometimes colloquially referred to as the timberdoodle,[2] is a small shorebird species found primarily in the eastern half of North America. Woodcocks spend most of their time on the ground in brushy, young-forest habitats, where the birds' brown, black, and gray plumage provides excellent camouflage.
The American woodcock is the only species of woodcock inhabiting North America.[3] Although classified with the sandpipers and shorebirds in the family Scolopacidae, the American woodcock lives mainly in upland settings. Its many folk names include timberdoodle, bogsucker, night partridge, brush snipe, hokumpoke, and becasse.[4]
The population of the American woodcock has fallen by an average of slightly more than 1% annually since the 1960s. Most authorities attribute this decline to a loss of habitat caused by forest maturation and urban development. Because of the male woodcock's unique, beautiful courtship flights, the bird is welcomed as a harbinger of spring in northern areas. It is also a popular game bird, with about 540,000 killed annually by some 133,000 hunters in the U.S.[5]
In 2008, wildlife biologists and conservationists released an American woodcock conservation plan presenting figures for the acreage of early successional habitat that must be created and maintained in the U.S. and Canada to stabilize the woodcock population at current levels, and to return it to 1970s densities.[6] Description
The American woodcock has a plump body, short legs, a large, rounded head, and a long, straight prehensile bill. Adults are 10 to 12 inches (25 to 30 cm) long and weigh 5 to 8 ounces (140 to 230 g).[7] Females are considerably larger than males.[8] The bill is 2.5 to 2.8 inches (6.4 to 7.1 cm) long.[4] Wingspans range from 16.5 to 18.9 inches (42 to 48 cm).[9] Illustration of American woodcock head and wing feathers Woodcock, with attenuate primaries, natural size, 1891
The plumage is a cryptic mix of different shades of browns, grays, and black. The chest and sides vary from yellowish-white to rich tans.[8] The nape of the head is black, with three or four crossbars of deep buff or rufous.[4] The feet and toes, which are small and weak, are brownish gray to reddish brown.[8] Woodcocks have large eyes located high in their heads, and their visual field is probably the largest of any bird, 360° in the horizontal plane and 180° in the vertical plane.[10]
The woodcock uses its long, prehensile bill to probe in the soil for food, mainly invertebrates and especially earthworms. A unique bone-and-muscle arrangement lets the bird open and close the tip of its upper bill, or mandible, while it is sunk in the ground. Both the underside of the upper mandible and the long tongue are rough-surfaced for grasping slippery prey.[4] Taxonomy
The genus Scolopax was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae.[11] The genus name is Latin for a snipe or woodcock.[12] The type species is the Eurasian woodcock (Scolopax rusticola).[13] Distribution and habitat
Woodcocks inhabit forested and mixed forest-agricultural-urban areas east of the 98th meridian. Woodcock have been sighted as far north as York Factory, Manitoba, and east to Labrador and Newfoundland. In winter, they migrate as far south as the Gulf Coast of the United States and Mexico.[8]
The primary breeding range extends from Atlantic Canada (Nova Scotia, Prince Edward Island, and New Brunswick) west to southeastern Manitoba, and south to northern Virginia, western North Carolina, Kentucky, northern Tennessee, northern Illinois, Missouri, and eastern Kansas. A limited number breed as far south as Florida and Texas. The species may be expanding its distribution northward and westward.[8]
After migrating south in autumn, most woodcocks spend the winter in the Gulf Coast and southeastern Atlantic Coast states. Some may remain as far north as southern Maryland, eastern Virginia, and southern New Jersey. The core of the wintering range centers on Louisiana, Mississippi, Alabama, and Georgia.[8] Based on the Christmas Bird Count results, winter concentrations are highest in the northern half of Alabama.
American woodcocks live in wet thickets, moist woods, and brushy swamps.[3] Ideal habitats feature early successional habitat and abandoned farmland mixed with forest. In late summer, some woodcocks roost on the ground at night in large openings among sparse, patchy vegetation.[8]Courtship/breeding habitats include forest openings, roadsides, pastures, and old fields from which males call and launch courtship flights in springtime. Nesting habitats include thickets, shrubland, and young to middle-aged forest interspersed with openings. Feeding habitats have moist soil and feature densely growing young trees such as aspen (Populus spp.), birch (Betula spp.), and mixed hardwoods less than 20 years of age, and shrubs, particularly alder (Alnus spp.). Roosting habitats are semiopen sites with short, sparse plant cover, such as blueberry barrens, pastures, and recently heavily logged forest stands.[8]
Migration
Woodcocks migrate at night. They fly at low altitudes, individually or in small, loose flocks. Flight speeds of migrating birds have been clocked at 16 to 28 mi/h (26 to 45 km/h). However, the slowest flight speed ever recorded for a bird, 5 mi/h (8 km/h), was recorded for this species.[14] Woodcocks are thought to orient visually using major physiographic features such as coastlines and broad river valleys.[8] Both the autumn and spring migrations are leisurely compared with the swift, direct migrations of many passerine birds.
In the north, woodcocks begin to shift southward before ice and snow seal off their ground-based food supply. Cold fronts may prompt heavy southerly flights in autumn. Most woodcocks start to migrate in October, with the major push from mid-October to early November.[15] Most individuals arrive on the wintering range by mid-December. The birds head north again in February. Most have returned to the northern breeding range by mid-March to mid-April.[8]
Migrating birds' arrival at and departure from the breeding range is highly irregular. In Ohio, for example, the earliest birds are seen in February, but the bulk of the population does not arrive until March and April. Birds start to leave for winter by September, but some remain until mid-November.[16] Behavior and ecology Food and feeding American woodcock catching a worm in a New York City park
Woodcocks eat mainly invertebrates, particularly earthworms (Oligochaeta). They do most of their feeding in places where the soil is moist. They forage by probing in soft soil in thickets, where they usually remain well-hidden. Other items in their diet include insect larvae, snails, centipedes, millipedes, spiders, snipe flies, beetles, and ants. A small amount of plant food is eaten, mainly seeds.[8] Woodcocks are crepuscular, being most active at dawn and dusk. Breeding
In spring, males occupy individual singing grounds, openings near brushy cover from which they call and perform display flights at dawn and dusk, and if the light levels are high enough, on moonlit nights. The male's ground call is a short, buzzy peent. After sounding a series of ground calls, the male takes off and flies from 50 to 100 yd (46 to 91 m) into the air. He descends, zigzagging and banking while singing a liquid, chirping song.[8] This high spiralling flight produces a melodious twittering sound as air rushes through the male's outer primary wing feathers.[17]
Males may continue with their courtship flights for as many as four months running, sometimes continuing even after females have already hatched their broods and left the nest. Females, known as hens, are attracted to the males' displays. A hen will fly in and land on the ground near a singing male. The male courts the female by walking stiff-legged and with his wings stretched vertically, and by bobbing and bowing. A male may mate with several females. The male woodcock plays no role in selecting a nest site, incubating eggs, or rearing young. In the primary northern breeding range, the woodcock may be the earliest ground-nesting species to breed.[8] Woodcock chick in nest Downy young are already well-camouflaged.
The hen makes a shallow, rudimentary nest on the ground in the leaf and twig litter, in brushy or young-forest cover usually within 150 yd (140 m) of a singing ground.[4] Most hens lay four eggs, sometimes one to three. Incubation takes 20 to 22 days.[3] The down-covered young are precocial and leave the nest within a few hours of hatching.[8] The female broods her young and feeds them. When threatened, the fledglings usually take cover and remain motionless, attempting to escape detection by relying on their cryptic coloration. Some observers suggest that frightened young may cling to the body of their mother, that will then take wing and carry the young to safety.[18] Woodcock fledglings begin probing for worms on their own a few days after hatching. They develop quickly and can make short flights after two weeks, can fly fairly well at three weeks, and are independent after about five weeks.[3]
The maximum lifespan of adult American woodcock in the wild is 8 years.[19] Rocking behavior American woodcocks sometimes rock back and forth as they walk, perhaps to aid their search for worms.
American woodcocks occasionally perform a rocking behavior where they will walk slowly while rhythmically rocking their bodies back and forth. This behavior occurs during foraging, leading ornithologists such as Arthur Cleveland Bent and B. H. Christy to theorize that this is a method of coaxing invertebrates such as earthworms closer to the surface.[20] The foraging theory is the most common explanation of the behavior, and it is often cited in field guides.[21]
An alternative theory for the rocking behavior has been proposed by some biologists, such as Bernd Heinrich. It is thought that this behavior is a display to indicate to potential predators that the bird is aware of them.[22] Heinrich notes that some field observations have shown that woodcocks will occasionally flash their tail feathers while rocking, drawing attention to themselves. This theory is supported by research done by John Alcock who believes this is a type of aposematism.[23] Population status
How many woodcock were present in eastern North America before European settlement is unknown. Colonial agriculture, with its patchwork of family farms and open-range livestock grazing, probably supported healthy woodcock populations.[4]
The woodcock population remained high during the early and mid-20th century, after many family farms were abandoned as people moved to urban areas, and crop fields and pastures grew up in brush. In recent decades, those formerly brushy acres have become middle-aged and older forest, where woodcock rarely venture, or they have been covered with buildings and other human developments. Because its population has been declining, the American woodcock is considered a "species of greatest conservation need" in many states, triggering research and habitat-creation efforts in an attempt to boost woodcock populations.
Population trends have been measured through springtime breeding bird surveys, and in the northern breeding range, springtime singing-ground surveys.[8] Data suggest that the woodcock population has fallen rangewide by an average of 1.1% yearly over the last four decades.[6] Conservation
The American woodcock is not considered globally threatened by the IUCN. It is more tolerant of deforestation than other woodcocks and snipes; as long as some sheltered woodland remains for breeding, it can thrive even in regions that are mainly used for agriculture.[1][24] The estimated population is 5 million, so it is the most common sandpiper in North America.[17]
The American Woodcock Conservation Plan presents regional action plans linked to bird conservation regions, fundamental biological units recognized by the U.S. North American Bird Conservation Initiative. The Wildlife Management Institute oversees regional habitat initiatives intended to boost the American woodcock's population by protecting, renewing, and creating habitat throughout the species' range.[6]
Creating young-forest habitat for American woodcocks helps more than 50 other species of wildlife that need early successional habitat during part or all of their lifecycles. These include relatively common animals such as white-tailed deer, snowshoe hare, moose, bobcat, wild turkey, and ruffed grouse, and animals whose populations have also declined in recent decades, such as the golden-winged warbler, whip-poor-will, willow flycatcher, indigo bunting, and New England cottontail.[25]
Leslie Glasgow,[26] the assistant secretary of the Interior for Fish, Wildlife, Parks, and Marine Resources from 1969 to 1970, wrote a dissertation through Texas A&M University on the woodcock, with research based on his observations through the Louisiana State University (LSU) Agricultural Experiment Station. He was an LSU professor from 1948 to 1980 and an authority on wildlife in the wetlands.[27] References

Because its population has been declining, the American woodcock is considered a "species of greatest conservation need" in many states, triggering research and habitat-creation efforts in an attempt to boost woodcock populations.
Population trends have been measured through springtime breeding bird surveys, and in the northern breeding range, springtime singing-ground surveys.[8] Data suggest that the woodcock population has fallen rangewide by an average of 1.1% yearly over the last four decades.[6] Conservation
The American woodcock is not considered globally threatened by the IUCN. It is more tolerant of deforestation than other woodcocks and snipes; as long as some sheltered woodland remains for breeding, it can thrive even in regions that are mainly used for agriculture.[1][24] The estimated population is 5 million, so it is the most common sandpiper in North America.[17]
The American Woodcock Conservation Plan presents regional action plans linked to bird conservation regions, fundamental biological units recognized by the U.S. North American Bird Conservation Initiative. The Wildlife Management Institute oversees regional habitat initiatives intended to boost the American woodcock's population by protecting, renewing, and creating habitat throughout the species' range.[6]
Creating young-forest habitat for American woodcocks helps more than 50 other species of wildlife that need early successional habitat during part or all of their lifecycles. These include relatively common animals such as white-tailed deer, snowshoe hare, moose, bobcat, wild turkey, and ruffed grouse, and animals whose populations have also declined in recent decades, such as the golden-winged warbler, whip-poor-will, willow flycatcher, indigo bunting, and New England cottontail.[25]
Leslie Glasgow,[26] the assistant secretary of the Interior for Fish, Wildlife, Parks, and Marine Resources from 1969 to 1970, wrote a dissertation through Texas A&M University on the woodcock, with research based on his observations through the Louisiana State University (LSU) Agricultural Experiment Station. He was an LSU professor from 1948 to 1980 and an authority on wildlife in the wetlands.[27] References

The American woodcock (Scolopax minor), sometimes colloquially referred to as the timberdoodle,[2] is a small shorebird species found primarily in the eastern half of North America. Woodcocks spend most of their time on the ground in brushy, young-forest habitats, where the birds' brown, black, and gray plumage provides excellent camouflage.
Tumblr media
The American woodcock is the only species of woodcock inhabiting North America.[3] Although classified with the sandpipers and shorebirds in the family Scolopacidae, the American woodcock lives mainly in upland settings. Its many folk names include timberdoodle, bogsucker, night partridge, brush snipe, hokumpoke, and becasse.[4]
The population of the American woodcock has fallen by an average of slightly more than 1% annually since the 1960s. Most authorities attribute this decline to a loss of habitat caused by forest maturation and urban development. Because of the male woodcock's unique, beautiful courtship flights, the bird is welcomed as a harbinger of spring in northern areas. It is also a popular game bird, with about 540,000 killed annually by some 133,000 hunters in the U.S.[5]
In 2008, wildlife biologists and conservationists released an American woodcock conservation plan presenting figures for the acreage of early successional habitat that must be created and maintained in the U.S. and Canada to stabilize the woodcock population at current levels, and to return it to 1970s densities.[6] Description
The American woodcock has a plump body, short legs, a large, rounded head, and a long, straight prehensile bill. Adults are 10 to 12 inches (25 to 30 cm) long and weigh 5 to 8 ounces (140 to 230 g).[7] Females are considerably larger than males.[8] The bill is 2.5 to 2.8 inches (6.4 to 7.1 cm) long.[4] Wingspans range from 16.5 to 18.9 inches (42 to 48 cm).[9] Illustration of American woodcock head and wing feathers Woodcock, with attenuate primaries, natural size, 1891
The plumage is a cryptic mix of different shades of browns, grays, and black. The chest and sides vary from yellowish-white to rich tans.[8] The nape of the head is black, with three or four crossbars of deep buff or rufous.[4] The feet and toes, which are small and weak, are brownish gray to reddish brown.[8] Woodcocks have large eyes located high in their heads, and their visual field is probably the largest of any bird, 360° in the horizontal plane and 180° in the vertical plane.[10]
The woodcock uses its long, prehensile bill to probe in the soil for food, mainly invertebrates and especially earthworms. A unique bone-and-muscle arrangement lets the bird open and close the tip of its upper bill, or mandible, while it is sunk in the ground. Both the underside of the upper mandible and the long tongue are rough-surfaced for grasping slippery prey.[4] Taxonomy
The genus Scolopax was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae.[11] The genus name is Latin for a snipe or woodcock.[12] The type species is the Eurasian woodcock (Scolopax rusticola).[13] Distribution and habitat
Woodcocks inhabit forested and mixed forest-agricultural-urban areas east of the 98th meridian. Woodcock have been sighted as far north as York Factory, Manitoba, and east to Labrador and Newfoundland. In winter, they migrate as far south as the Gulf Coast of the United States and Mexico.[8]
The primary breeding range extends from Atlantic Canada (Nova Scotia, Prince Edward Island, and New Brunswick) west to southeastern Manitoba, and south to northern Virginia, western North Carolina, Kentucky, northern Tennessee, northern Illinois, Missouri, and eastern Kansas. A limited number breed as far south as Florida and Texas. The species may be expanding its distribution northward and westward.[8]
After migrating south in autumn, most woodcocks spend the winter in the Gulf Coast and southeastern Atlantic Coast states. Some may remain as far north as southern Maryland, eastern Virginia, and southern New Jersey. The core of the wintering range centers on Louisiana, Mississippi, Alabama, and Georgia.[8] Based on the Christmas Bird Count results, winter concentrations are highest in the northern half of Alabama.
American woodcocks live in wet thickets, moist woods, and brushy swamps.[3] Ideal habitats feature early successional habitat and abandoned farmland mixed with forest. In late summer, some woodcocks roost on the ground at night in large openings among sparse, patchy vegetation.[8]Courtship/breeding habitats include forest openings, roadsides, pastures, and old fields from which males call and launch courtship flights in springtime. Nesting habitats include thickets, shrubland, and young to middle-aged forest interspersed with openings. Feeding habitats have moist soil and feature densely growing young trees such as aspen (Populus spp.), birch (Betula spp.), and mixed hardwoods less than 20 years of age, and shrubs, particularly alder (Alnus spp.). Roosting habitats are semiopen sites with short, sparse plant cover, such as blueberry barrens, pastures, and recently heavily logged forest stands.[8]
Migration
Woodcocks migrate at night. They fly at low altitudes, individually or in small, loose flocks. Flight speeds of migrating birds have been clocked at 16 to 28 mi/h (26 to 45 km/h). However, the slowest flight speed ever recorded for a bird, 5 mi/h (8 km/h), was recorded for this species.[14] Woodcocks are thought to orient visually using major physiographic features such as coastlines and broad river valleys.[8] Both the autumn and spring migrations are leisurely compared with the swift, direct migrations of many passerine birds.
In the north, woodcocks begin to shift southward before ice and snow seal off their ground-based food supply. Cold fronts may prompt heavy southerly flights in autumn. Most woodcocks start to migrate in October, with the major push from mid-October to early November.[15] Most individuals arrive on the wintering range by mid-December. The birds head north again in February. Most have returned to the northern breeding range by mid-March to mid-April.[8]
Tumblr media
Migrating birds' arrival at and departure from the breeding range is highly irregular. In Ohio, for example, the earliest birds are seen in February, but the bulk of the population does not arrive until March and April. Birds start to leave for winter by September, but some remain until mid-November.[16] Behavior and ecology Food and feeding American woodcock catching a worm in a New York City park
Woodcocks eat mainly invertebrates, particularly earthworms (Oligochaeta). They do most of their feeding in places where the soil is moist. They forage by probing in soft soil in thickets, where they usually remain well-hidden. Other items in their diet include insect larvae, snails, centipedes, millipedes, spiders, snipe flies, beetles, and ants. A small amount of plant food is eaten, mainly seeds.[8] Woodcocks are crepuscular, being most active at dawn and dusk. Breeding
In spring, males occupy individual singing grounds, openings near brushy cover from which they call and perform display flights at dawn and dusk, and if the light levels are high enough, on moonlit nights. The male's ground call is a short, buzzy peent. After sounding a series of ground calls, the male takes off and flies from 50 to 100 yd (46 to 91 m) into the air. He descends, zigzagging and banking while singing a liquid, chirping song.[8] This high spiralling flight produces a melodious twittering sound as air rushes through the male's outer primary wing feathers.[17]
Males may continue with their courtship flights for as many as four months running, sometimes continuing even after females have already hatched their broods and left the nest. Females, known as hens, are attracted to the males' displays. A hen will fly in and land on the ground near a singing male. The male courts the female by walking stiff-legged and with his wings stretched vertically, and by bobbing and bowing. A male may mate with several females. The male woodcock plays no role in selecting a nest site, incubating eggs, or rearing young. In the primary northern breeding range, the woodcock may be the earliest ground-nesting species to breed.[8] Woodcock chick in nest Downy young are already well-camouflaged.
The hen makes a shallow, rudimentary nest on the ground in the leaf and twig litter, in brushy or young-forest cover usually within 150 yd (140 m) of a singing ground.[4] Most hens lay four eggs, sometimes one to three. Incubation takes 20 to 22 days.[3] The down-covered young are precocial and leave the nest within a few hours of hatching.[8] The female broods her young and feeds them. When threatened, the fledglings usually take cover and remain motionless, attempting to escape detection by relying on their cryptic coloration. Some observers suggest that frightened young may cling to the body of their mother, that will then take wing and carry the young to safety.[18] Woodcock fledglings begin probing for worms on their own a few days after hatching. They develop quickly and can make short flights after two weeks, can fly fairly well at three weeks, and are independent after about five weeks.[3]
The maximum lifespan of adult American woodcock in the wild is 8 years.[19] Rocking behavior American woodcocks sometimes rock back and forth as they walk, perhaps to aid their search for worms.
American woodcocks occasionally perform a rocking behavior where they will walk slowly while rhythmically rocking their bodies back and forth. This behavior occurs during foraging, leading ornithologists such as Arthur Cleveland Bent and B. H. Christy to theorize that this is a method of coaxing invertebrates such as earthworms closer to the surface.[20] The foraging theory is the most common explanation of the behavior, and it is often cited in field guides.[21]
An alternative theory for the rocking behavior has been proposed by some biologists, such as Bernd Heinrich. It is thought that this behavior is a display to indicate to potential predators that the bird is aware of them.[22] Heinrich notes that some field observations have shown that woodcocks will occasionally flash their tail feathers while rocking, drawing attention to themselves. This theory is supported by research done by John Alcock who believes this is a type of aposematism.[23] Population status
How many woodcock were present in eastern North America before European settlement is unknown. Colonial agriculture, with its patchwork of family farms and open-range livestock grazing, probably supported healthy woodcock populations.[4]
The woodcock population remained high during the early and mid-20th century, after many family farms were abandoned as people moved to urban areas, and crop fields and pastures grew up in brush. In recent decades, those formerly brushy acres have become middle-aged and older forest, where woodcock rarely venture, or they have been covered with buildings and other human developments. Because its population has been declining, the American woodcock is considered a "species of greatest conservation need" in many states, triggering research and habitat-creation efforts in an attempt to boost woodcock populations.
Population trends have been measured through springtime breeding bird surveys, and in the northern breeding range, springtime singing-ground surveys.[8] Data suggest that the woodcock population has fallen rangewide by an average of 1.1% yearly over the last four decades.[6] Conservation
The American woodcock is not considered globally threatened by the IUCN. It is more tolerant of deforestation than other woodcocks and snipes; as long as some sheltered woodland remains for breeding, it can thrive even in regions that are mainly used for agriculture.[1][24] The estimated population is 5 million, so it is the most common sandpiper in North America.[17]
The American Woodcock Conservation Plan presents regional action plans linked to bird conservation regions, fundamental biological units recognized by the U.S. North American Bird Conservation Initiative. The Wildlife Management Institute oversees regional habitat initiatives intended to boost the American woodcock's population by protecting, renewing, and creating habitat throughout the species' range.[6]
Creating young-forest habitat for American woodcocks helps more than 50 other species of wildlife that need early successional habitat during part or all of their lifecycles. These include relatively common animals such as white-tailed deer, snowshoe hare, moose, bobcat, wild turkey, and ruffed grouse, and animals whose populations have also declined in recent decades, such as the golden-winged warbler, whip-poor-will, willow flycatcher, indigo bunting, and New England cottontail.[25]
Leslie Glasgow,[26] the assistant secretary of the Interior for Fish, Wildlife, Parks, and Marine Resources from 1969 to 1970, wrote a dissertation through Texas A&M University on the woodcock, with research based on his observations through the Louisiana State University (LSU) Agricultural Experiment Station.

Window strikes are an issue in almost every major U.S. city. Birds don’t see clear or reflective glass and don’t understand it’s a lethal barrier. When they see plants or bushes through windows or reflected in them, they head for them, killing themselves in the process. Birds that migrate at night, like sparrows and warblers, rely on the stars to navigate. Bright lights from buildings both attract and confuse them, leading to window strikes or birds flying around the lights until they die from exhaustion — a phenomenon known as fatal light attraction. In 2017, for example, almost 400 passerines became disoriented in a Galveston, Texas, skyscraper’s floodlights and died in collisions with windows. “Unfortunately, it is really common,” said Matt Igleski, executive director of the Chicago Audubon Society. “We see this in pretty much every major city during spring and fall migration. This (the window strikes at McCormick Place) was a very catastrophic single event, but when you add it all up (across the country), it’s always like that.” [...] Window strikes and fatal light attraction are easily preventable, said Anna Pidgeon, an avian ecologist at the University of Wisconsin-Madison. Building managers can simply dim their lights, she said, and architects can design windows with markings in the glass that birds can easily recognize. People can add screens, paint their windows or apply decals to the glass as well. New York City has taken to shutting off the twin beams of light symbolizing the World Trade Center for periods of time during its annual Sept. 11 memorial ceremony to prevent birds from becoming trapped in the light shafts. The National Audubon Society launched a program in 1999 called Lights Out, an effort to encourage urban centers to turn off or dim lights during migration months. Nearly 50 U.S. and Canadian cities have joined the movement, including Toronto, New York, Boston, San Diego, Dallas and Miami. Chicago also participates in the Lights Out program. The city council in 2020 passed an ordinance requiring bird safety measures in new buildings but has yet to implement the requirements. The first buildings at McCormick Place were constructed in 1959.

Juneteenth (June 19th, 1865)

Everyone knows Juneteenth as the holiday commemorating the end of slavery in the United States.
But not everyone knows that the slaves weren't officially free.
This is the story.
Juneteenth National Independence Day, also known as Black Independence Day, Emancipation Day, Freedom Day, Jubilee Day, and Juneteenth Independence Day, is a holiday commemorating the end of slavery in the United States, observed annually on June 19th.
Juneteenth honors the end of slavery in the United States and is considered the longest-running African-American holiday.
Juneteenth, short for "June Nineteenth," marks the day in 1895 that Federal troops arrived in Galveston, Texas, to take control of the state and ensure that all slaves were freed. The troops' arrival came almost two and a half years after the Emancipation Proclamation.
Two months earlier, Confederate General Robert E. Lee had surrendered at Appomattox Courthouse in Virginia, but slavery had remained relatively unaffected in Texas -- Until U.S. General Gordon stood on Texas soil and read General Orders No. 3: "The people of Texas are informed that, in accordance with a Proclamation from the Executive of the United States, all slaves are free."
The Emancipation Proclamation
On January 1st, 1863, The Emancipation Proclamation was issued by President Abraham Lincoln. It established that all enslaved people in the Confederate state in rebellion against the Union "shall be then, thenceforward, and forever free." 
However, The Emancipation did not immediately set the slaves free.
The Proclamation only applied to places under Confederate control and not to slave-holding border states or rebel areas already under Union control. But when Northern troops advanced into the Confederate South, many slaves fled behind Union lines.
In Texas, slavery continued as the state experienced no large-scale fighting or a significant presence of Union troops. Many slave masters from outside of Texas had moved there, as they viewed it as a safe haven for slavery.
After the war ended in the spring of 1865, General Granger's arrival in Galveston the following June signaled freedom for the 250,000 slaves in Texas. Although emancipation didn't happen for everyone, slave masters withheld the information until after harvest season.
Celebrations broke out among newly freed African-Americans, and that was the beginning of Juneteenth. The following December, slavery in America was formally abolished with the adoption of the 13th Amendment.
On June 19th, 1865, freedmen in Texas organized the first annual "Jubilee Day". In the following decades, Juneteenth celebrations featured barbecues, music, prayer services, and other activities, and as African Americans migrated from Texas to other parts of the country, so did the Juneteenth tradition.
In 1979, Texas became the first state to make Juneteenth an official holiday, other states followed over the years. In June 2021, Congress passed a resolution establishing Juneteenth as a national holiday. On June 17th, 2021, President Biden officially signed it into law. 160 years later, it officially became a federal holiday.

Discovering the Optimal Season: The Best Time to Experience Big Bend Texas
Tumblr media
Nestled along the Rio Grande in the vast expanse of West Texas, Big Bend National Park stands as a testament to nature's grandeur. Spanning over 800,000 acres, this rugged wilderness offers a myriad of outdoor adventures, from hiking through towering canyons to stargazing under the vast desert sky. But when is the best time to visit this remote and awe-inspiring destination? Let's unravel the seasons of Big Bend and discover the optimal time to experience its wonders.
Spring: March to May
As winter loosens its grip and the desert begins to bloom, spring emerges as one of the prime seasons to visit Big Bend. Temperatures are mild, ranging from comfortable highs in the 70s to cooler evenings. Wildflowers carpet the desert floor in a riot of color, creating a stunning backdrop for hiking and photography. Spring also marks the peak of bird migration, making it a paradise for birdwatchers.

New York mayor 'shocked' that migrant children as young as nine months secretly sent to his city
New York's mayor said he was shocked that at least 239 minors arrived incognito after being separated from parents on the Mexican border.
While Donald Trump signed the end of a policy of separation of families at the border that provoked outrage in the United States and abroad, Democratic Mayor Bill de Blasio went into a a reception center for migrant children in Harlem, where a television crew had filmed the previous night some girls arriving secretly, apparently separated from their parents at the border.
The segregated minors included a nine-month-old baby and traumatized children, many with lice, bedbugs or contagious diseases.
Mr De Blasio emerged from the reception centre saying he was "shocked to learn" how many children separated from their parents had been sent to New York, explaining that this single center in Harlem had received 239 children without the knowledge of city authorities.
"How is it possible that none of us knew that there (were) 239 kids right here in our city?" he said. "How is the federal government holding back that information from the people of this city and holding back the help that these kids could need?"
"The mental health issues alone, they made clear to us, are very real; very painful," De Blasio stressed.
The Cayuga Center, which has classrooms in a six-story building across the street from an elevated train line, has a federal contract to place unaccompanied immigrant children in short-term foster care. Officials at the center did not immediately return phone calls seeking comment.
Mr De Blasio said the staff there told him it has taken in about 350 children since President Donald Trump's administration implemented its "zero tolerance" policy this spring calling for the criminal prosecution of all adults caught crossing the border illegally.
He is off to join other US mayors Thursday in Texas to visit a childcare center and denounce the migration policy of the Trump administration.

Sen. Ted Cruz, R-Texas, released a graphic video highlighting the brutality of what he calls the "Narco slave trade" at the U.S.-Mexico border.
The video begins with Cruz and border officials tending to a group of migrants who crossed the border late in the night. He highlights that the vast majority of migrants are being economically exploited by the drug cartels bringing them into the U.S.
"These children come in in debt to vicious cartels thousands and thousands of dollars. The teenage boys work for the gangs in every city in America, and the teenage girls experience a hell worse than that, with far too many of them human trafficked into sex slavery," Cruz says in the video. "Joe Biden and Kamala Harris are responsible for the worst plague of slavery in America since the Civil War."
"This is not compassionate. This is not humane. This is barbaric," Cruz adds as the footage cycles graphic photos of migrants who have died attempting to cross the border.
President Biden's administration has presided over record-breaking border crossings in both 2021 and 2022.
The administration has repeatedly attempted to dismiss border surges as a yearly pattern, but while the southern border has seen a pattern of increases in migration each spring, the surges in both 2021 and 2022 far outpaced previous years.
Biden claimed in March 2021 that the border surge was "what happens every year." The U.S. saw 1.7 million border crossings by the end of that year, an all-time record.
2022 is expected to break that record, however.

Do American robins migrate?
Tumblr media Tumblr media
american robins bird migration
Spring singer or snow sentinel?
The best known of the songbirds is the American robin, also known as the bird of North America. It is usually more common in winter. Now the question is: do robin birds migrate? The answer is yes and no. We usually say robins are winter birds but they are able to adapt to warm as well. But that doesn't mean they are immune to winter weather.
Winter Strategy
The opposite of Hummingbird is a native of far Durant. They are concentrated in the south most of the time. They usually react during winter in two ways. Robins can also tolerate very cold weather. Many are moving south. The northern Canada robin vacates many wintering flocks of birds as far south as Texas and Florida. Birds that come and go are not used to hot weather. They have a similar body structure and add warm, downy feathers to their plumage. As food decreases in warmer weather, they begin to search for food supplies due to the scarcity of insects and insects. Food is usually the main motivation of such birds. Declining insect or invertebrate numbers aren't a problem for everyone - and a good number tend to be in the north, which is another way robin birds respond to winter. They took observations in southern Canadian provinces and US state locations in January. They are seen occupying several important places. By changing the diet they usually turn to vitamin-rich invertebrates and winter fruits including juniper, holly, crabapple and hawthorn. During summer and spring robin birds aggressively defend their territory and raise their young. During the winter season they become nomadic and engage in intense quest to regain their beloved cold weather. Robins speed up in the weather, too. They can confirm their position in case of heavy snowfall. Robin bird also roams around stealing jays in winter and these jays which may number hundreds or thousands. In summer and spring, the birds form opposite territorial pairs.
Flocking offers important benefits:
A group of them have large eyes that can quickly spot any predator. They are one of the most adept at discovering food. Finally, robins usually make little noise in winter. They all live together. As spring arrives, they begin to sing and produce mating hormones. They usually maintain a flexible presence. For some changes and and dramatically reduces the profile of robins or their populations, making them common and leading some people to assume their absence. So how do robins decide whether to stay or leave for the winter? This is not precisely answered but gender may play a role. Male birds are more likely than females, usually in northern areas. It clearly provides territorial advantages that allow men to be preemptively inserted into chiefdoms everywhere.   Spring actually causes northern flocks of robins to disperse and resume their invertebrate diet. such as picking and eating earthworms and other vertebrates from the soil. At the same time the robins with migraines return from the southern region. Males usually arrive two to three weeks earlier than females. Males on both sides sing very loudly as they begin to defend territory. The result?
Tumblr media
when american robins are everywhere?
People think robins are everywhere now.
Save the Robin Like other birds, the robin seems to have greatly benefited the development of birding and agriculture. Population is increasing which is a threat to any adaptation Yajna tribes are vulnerable to many of the same factors. Moreover, pesticide poisoning poses an important threat to their conservation. Because the American robin roams lawns and other open spaces that are often poisoned areas and eats. Although DDT has been banned in the United States, it is known as a toxic chemical. Examples include neonicotinoids, chlorpyrifos and glyphosate (used in the well-known herbicide Roundup) still in use. Insecticides kill earthworms, which are a major part of the bird's diet. Because American robins mostly forage and feed on the ground, they pose a major threat to feral cats. Moreover, the cars, towers and various electrical things and the current modern age of cars and networks are making their lives more difficult. Various organizations have adopted this policy and are coming forward to help protect them from the dangers. It is better to save them to protect them in the society. Because many birds that are beneficial to society are leaving us and disappearing due to various reasons. Various ornithological organizations are working for birds. Read the full article

Bungled rollout of Dallas County software has clouded court activity
Tumblr media
We’ve long had concerns about the work ethic of Dallas County’s felony court judges.
Their slow progress at chipping away at the huge backlog of cases amassed during the pandemic has been the topic of several editorials in the last two years.
Dallas County commissioners also publicly criticized the judges, saying some weren’t working hard enough to clear cases while victims and defendants waited for justice.
The judges appeared last spring to be making progress; data from the Office of Court Administration, an arm of the Texas judicial branch, showed the backlog was leveling off.
Tumblr media
But has that progress continued?
Who knows.
For nearly a year Dallas County has not been reporting this important court data to the Office of Court Administration every month as required.
Tumblr media
That’s because the county has bungled the rollout of a new criminal case management software program, and it hasn’t been able to send reliable court data to the state since April.
The problem, rooted in the migration of case files from the county’s 40-year-old Forvus database to Tyler Technologies’ Odyssey system, has caused many other problems, too, including rising jail costs as inmates linger behind bars waiting for their release or transfer paperwork.
Dallas County District Clerk Felicia Pitre provided us some hope last week, however. She told us in an email that her office, Tyler and the county IT department have been “meeting daily” and have corrected “thousands of errors” discovered in the conversion between the two systems.
That conversion was completed Thursday, she said, and she expects to begin sending felony court data to the Office of Court Administration this week.
Even better, she said the county will also soon be able to comply with a new state law requiring her to provide detailed information on the activities of each court specifically, including the number of jury trials held, continuances granted, plea agreements approved and use of visiting judges.
That’s good news to Alejandra Pena, the Office of Court Administration’s director of data and research, who told us her office is eager to receive this information and incorporate it into its 2023 annual statistical report of the Texas judiciary.
That report has been held up in part because of the lack of data from Dallas County, the second largest court system in the state, she said.
It’s also good news for all of us, whether we realize it or not.
The safety of our communities relies in part on a well-functioning criminal court system.
Transparency is paramount to holding elected judges accountable for delivering justice, not only by looking at how the courts are functioning as a whole, but also by reviewing how hard and efficiently each judge in particular is working.

How Do Animals React during A Total Solar Eclipse? Scientists Plan To Find Out
Scientists Will Observe How Animals' Routines at Several Zoos are Disrupted.
— By Christina Larson | March 7, 202
Tumblr media
Washington — When a total solar eclipse transforms day into night, will tortoises start acting romantic? Will giraffes gallop? Will apes sing odd notes?
Researchers will be standing by to observe how animals’ routines at the Fort Worth Zoo in Texas are disrupted when skies dim on April 8. They previously detected other strange animal behaviors in 2017 at a South Carolina zoo that was in the path of total darkness.
“To our astonishment, most of the animals did surprising things,” said Adam Hartstone-Rose, a North Carolina State University researcher who led the observations published in the journal Animals.
While there are many individual sightings of critters behaving bizarrely during historic eclipses, only in recent years have scientists started to rigorously study the altered behaviors of wild, domestic and zoo animals.
Seven years ago, Galapagos tortoises at the Riverbanks Zoo in Columbia, South Carolina, “that generally do absolutely nothing all day … during the peak of the eclipse, they all started breeding,” said Hartstone-Rose. The cause of the behavior is still unclear.
A mated pair of Siamangs, gibbons that usually call to each other in the morning, sang unusual tunes during the afternoon eclipse. A few male giraffes began to gallop in “apparent anxiety.” The flamingos huddled around their juveniles.
Researchers say that many animals display behaviors connected with an early dusk.
In April, Hartstone-Rose’s team plans to study similar species in Texas to see if the behaviors they witnessed before in South Carolina point to larger patterns.
Several other zoos along the path are also inviting visitors to help track animals, including zoos in Little Rock, Arkansas; Toledo, Ohio; and Indianapolis.
This year’s full solar eclipse in North America crisscrosses a different route than in 2017 and occurs in a different season, giving researchers and citizen scientists opportunities to observe new habits.
“It’s really high stakes. We have a really short period to observe them and we can’t repeat the experiment," said Jennifer Tsuruda, a University of Tennessee entomologist who observed honeybee colonies during the 2017 eclipse.
The honeybees that Tsuruda studied decreased foraging during the eclipse, as they usually would at night, except for those from the hungriest hives.
“During a solar eclipse, there’s a conflict between their internal rhythms and external environment,” said University of Alberta's Olav Rueppell, adding that bees rely on polarized light from the sun to navigate.
Nate Bickford, an animal researcher at Oregon Institute of Technology, said that “solar eclipses actually mimic short, fast-moving storms,” when skies darken and many animals take shelter.
After the 2017 eclipse, he analyzed data from tracking devices previously placed on wild species to study habitat use. Flying bald eagles change the speed and direction they’re moving during an eclipse, he said. So do feral horses, “probably taking cover, responding to the possibility of a storm out on the open plains.”
The last full U.S. solar eclipse to span coast to coast happened in late summer, in August. The upcoming eclipse in April gives researchers an opportunity to ask new questions including about potential impacts on spring migration.
Most songbird species migrate at night. “When there are night-like conditions during the eclipse, will birds think it’s time to migrate and take flight?” said Andrew Farnsworth of Cornell University.
His team plans to test this by analyzing weather radar data – which also detects the presence of flying birds, bats and insects – to see if more birds take wing during the eclipse.
As for indoor pets, they may react as much to what their owners are doing – whether they’re excited or nonchalant about the eclipse – as to any changes in the sky, said University of Arkansas animal researcher Raffaela Lesch.
“Dogs and cats pay a lot of attention to us, in addition to their internal clocks,” she said.

David Willard has been checking the grounds of Chicago's lakefront exhibition center for dead birds for 40 years. On Thursday morning he found something horrible: Hundreds of dead songbirds, so thick they looked like a carpet.Nearly 1,000 songbirds perished during the night after crashing into the McCormick Place Lakeside Center 's windows, the result, according to avian experts, of a deadly confluence of prime migration conditions, rain and the low-slung exhibition hall's lights and window-lined walls.“It was just like a carpet of dead birds at the windows there,” said Willard, a retired bird division collections manager at the Chicago Field Museum, where his duties included administering, preserving and cataloging the museum's collection of 500,000 bird specimens as well as searching for bird strikes as part of migration research.“A normal night would be zero to 15 (dead) birds. It was just kind of a shocking outlier to what we've experienced," Willard said. "In 40 years of keeping track of what's happening at McCormick, we've never seen anything remotely on that scale."Researchers estimate hundreds of millions of birds die in window strikes in the United States each year. Scientists with the Smithsonian Conservation Biology Institute and the U.S. Fish and Wildlife Service released a study in 2014 that put the number between 365 million and 988 million birds annually.Window strikes are an issue in almost every major U.S. city. Birds don't see clear or reflective glass and don't understand it's a lethal barrier. When they see plants or bushes through windows or reflected in them, they head for them, killing themselves in the process.Birds that migrate at night, like sparrows and warblers, rely on the stars to navigate. Bright lights from buildings both attract and confuse them, leading to window strikes or birds flying around the lights until they die from exhaustion — a phenomenon known as fatal light attraction. In 2017, for example, almost 400 passerines became disoriented in a Galveston, Texas, skyscraper's floodlights and died in collisions with windows.“Unfortunately, it is really common,” said Matt Igleski, executive director of the Chicago Audubon Society. “We see this in pretty much every major city during spring and fall migration. This (the window strikes at McCormick Place) was a very catastrophic single event, but when you add it all up (across the country), it's always like that.”Conditions were ripe for a massive wave of songbird southern migration over Chicago on Wednesday evening, said Stan Temple, a retired University of Wisconsin-Madison wildlife ecology professor and avian expert.Small songbirds feed during the day and migrate at night to avoid air turbulence and predators. They’ve been waiting for northerly winds to give them a boost south, Temple said, but September saw unusually warm southern winds that kept birds in a holding pattern here. On Wednesday evening a front swept south, providing a tailwind, and thousands of birds took to the skies.“You had all these birds that were just raring to go but they’ve been held up with this weird September and October with temperatures way above normal,” Temple said. “You had this huge pack of birds take off.”The birds swept south over Chicago, following the Lake Michigan shoreline - and right into a maze of illuminated structures, Temple said.Pre-dawn rain forced the birds to drop to lower altitudes, where they found McCormick Place’s lights on, Willard said. According to the field museum’s count, 964 birds died at the center. That’s about 700 more than have been found at the center at any point in the last 40 years, Willard said. Members of 33 species died, according to the field museum; most of them were palm and yellow-rumped warblers.Window strikes and fatal light attraction are easily preventable, said Anna Pidgeon, an avian ecologist at the University of Wisconsin-Madison. Building managers can simply dim their lights, she said, and architects can design windows with markings in the glass that birds can easily recognize.
People can add screens, paint their windows or apply decals to the glass as well.New York City has taken to shutting off the twin beams of light symbolizing the World Trade Center for periods of time during its annual Sept. 11 memorial ceremony to prevent birds from becoming trapped in the light shafts. The National Audubon Society launched a program in 1999 called Lights Out, an effort to encourage urban centers to turn off or dim lights during migration months. Nearly 50 U.S. and Canadian cities have joined the movement, including Toronto, New York, Boston, San Diego, Dallas and Miami.Chicago also participates in the Lights Out program. The city council in 2020 passed an ordinance requiring bird safety measures in new buildings but has yet to implement the requirements. The first buildings at McCormick Place were constructed in 1959.Cynthia McCafferty, a spokesperson for McCormick Place, said the exhibition hall participates in Lights Out and interior lighting is turned off unless staff, clients or visitors need it. She added that the center maintains a six-acre (2.4-hectare) bird sanctuary.McCafferty said an event has been going on all week at the center so the lights have been on when the building was occupied but turned off when it wasn't. She said she wasn't sure what time the window strikes occurred or whether the center was occupied then.“It's an odd building,” Willard said of the exhibition center. “When it was built, people weren't thinking about bird safety. They still aren't in most architecture. It's right on the lakefront. There are many nights when it's lit up. People are describing the whole night of migration as part of a once in a lifetime thing ... (but) this still is an unacceptable intrusion by humans and their architecture. Just terribly sad and dramatic.”—-This story has been updated to correct the name of the exhibition center to McCormick Place, not McCormick Center.
