A redraw of a painting, which I liked, from the game Owlboy ^^ It took me several days of work and perseverance to do it I hope you like it, my poor little eyes have trouble seeing if it's beautiful or not so much I worked on it 😂 Hope your eyes will tell me ^^

Strange Symmetries #23: Convergent Earvolution

Although it's not visible externally, owls have one of the most striking modern examples of asymmetry. The ears of many species are uneven, with the right ear opening positioned higher up than the left, giving them the ability to pinpoint the sounds of their prey much more accurately.

But surprisingly this isn't a unique anatomical trait that only ever evolved once in their common ancestor.

Instead, multiple different lineages of owls have actually convergently evolved wonky ears somewhere between four and seven separate times.

The boreal owl (Aegolius funereus), also known as Tengmalm's owl, is a small 25cm long (~10") true owl found across much of the northern parts of both Eurasia and North America. While most other owls' asymmetrical ear openings are formed just by soft tissue, the boreal owl's lopsided ears are actually visible in the bones of its skull.

But despite how many times owls have convergently evolved asymmetrical ears, and how successful this adaptation has been for them, for a long time it seemed to be something that no other animals have ever mimicked.

In the early 2000s asymmetric ears were reported in the skulls of some troodontid dinosaurs, which seem to have been nocturnal hearing-based hunters similar to owls, but proper details on this feature still haven't been formally published.

Then, just a couple of weeks ago, another example was finally announced.

The night parrot (Pezoporus occidentalis) is a small ground-dwelling parrot found in Australia, close to the same size as the boreal owl at around 22cm long (~9"). Critically endangered and very elusive, it's rarely seen and little is known about it – and it was presumed extinct for much of the 20th century, until more recent sightings of living individuals confirmed that the species is still hanging on.

Recent studies of preserved museum specimens have revealed that it seems to have poor night vision but excellent hearing, and that its right ear opening is noticeably asymmetrical, bulging out sideways from its skull. Much like owls the night parrot relies on acute directional hearing to navigate in darkness, but since its diet consists mainly of seeds it's probably not using this ability to locate food sources. Instead it may be listening out to keep track of the precise locations of other parrots, and for the approach of predators – so its sharp sense of hearing may be the reason this unique bird has so far just barely managed to survive the presence of invasive cats and foxes.

i have gog ocs now. i love them (i've had arche for years actually but only just now drew her)

and yeah arche is purple but i literally color picked a photo reference of a melanistic barn owl LMAO

hawthorne was a guard at st. aegolius whose moon blinking was botched, and arche is a spy for the guardians stationed at st aggies. she helps hawthorne escape and they become mates once they get back to the great ga'hoole tree, since they're both known by the st. aggies guards and pretty much designated KOS arche was retired from the search and rescue chaw and hawthorne was given time to rest and recover from his time at st aggies

i am very normal about guardians of ga'hoole, please ask me about these goobers

their toyhouses: arche - hawthorne

That post about the husbands as ANCH Blathers and Flick? Yeah Well my headcanon is that Aziraphale has a private book collection on the island and whenever Crowley is there to survey the local flora and maintain the community blooms, he usually makes a trip to Aegolius' Boobookery House to 'save' the 'entomophobic' bookkeeper from household pests and then stays for a grateful nightcap

#pandaa art #ineffable husbands #good omens fanart #I spent too long looking at owl species for this #and boobooks and aegoliuses dont even look like how I designed Aziraphale #the situation is just like how the angel Aziraphale is not british or gay #but the species boobooks and owls of 'ill omens' was too good to not use #vest and dress shirt is part of feather design #hes just wearing his ring bowtie and splats #and in this unrealistic world Crowley is a reptile hybrid #Aziraphale is like a white eagle-owl or some other Bubo #good omens au
