Just that it’s odd. Owls, all birds, have eyes that are of course the same, and are round.
Perhaps it’s just the angle of the camera but one eye looks almost human shaped, and it must be in bright light because the pupils are very small. Owls are creatures of the night, not daylight.
Just an oddity that has nagged at my brain since I first saw the picture.
Good observation. Wonder if there something to that. I don’t know much about birds.
