Anatomy: Axillaries

Published by at 7:26 am under Bird Anatomy

There are plenty of obscure anatomy words I haven’t covered yet.  For instance, what about axillaries?

Axillaries are the bird’s armpits, circled here in yellow. 

Usually they are unremarkable because they match the wing color but every once in a while there’s a surprise.  Black-bellied plovers and rose-breasted grosbeaks are two examples.  The American robin is another. 

If you hadn’t seen this picture would you have known that the orange color of the robin’s breast extends to its axillaries?

    Ha ha ha! When I read the title, I thought didn’t I just read an anatomy one recently? I had to laugh after reading the first sentence. :)

    Thanks for the anatomy lessons.
