Human arm top, bird wing bottom |
Humerus - Innermost bone, between body and elbow.
Ulna/Radius - middle or forearm bones, between elbow and wrist. The secondary feathers are attached to the ulna.
Hand - Outermost bone, some metacarpals are missing, some are fused together. One of the digits is the thumb or alula, a small group of three or four feathers are attached to the bone. The ten primary flight feathers (nine in some perching birds) are attached to the hand.
Thanks for this. I'm trying to learn bird anatomy on the fly. I believe I'll draw better birds once I learn their basic anatomy. Can you recommend any books?
