These are some bird skeleton studies I did yesterday. The two wings, the leg, and the skull with vertebrae were drawn from a chicken skeleton. The other three skulls were drawn from reference photos found on skullsite.com. They are each labeled with the bird they came from.
The text is a collection of various notes on parrots I found from books and the internet while drawing these. I am aware that the Macaw list is incomplete.
This is an additional Macaw skull that I did later that same day in a different sketchbook.
