Some one took the liberty of drawing the sketch of the crow. The sketch shows why the crow appears like a gorilla.
Kaeli Swift, a corvid researcher has also given explanation for this strange looking crow.
There’s a very strange (uncredited) video of crow making the rounds on reddit. Here’s the deal. First, this is a large-billed crow, which is why the face is looking a little out of proportion.
Second, this bird is not missing its legs and propping itself up with its wings, that would be physically impossible. Also, not that it’s relevant to the answer, but a crow without legs couldn’t fly, because it couldn’t generate any lift. So legless crow is a dead crow.
What it’s actually doing is sunning itself. When birds sun they drop their wings and cock their tails. At the right angle that could obscure the legs and tail making it look like they’re missing.
Usually, the mouth is open and the body is closer to the ground, making the behavior more obvious, but perhaps the videographer caught it in a moment of transition.
In any case, sunning like this is a common behavior among birds. Sometimes it’s about warming up but a lot of times you’ll see them do it when it’s hot out. In these cases, it’s about feather care. Sun exposure can reduce feather-degrading bacteria and mites.
