I'm a pretty big fan of this animation archive site. It's a good look if you're into old animation, because they are archiving as much animation as they can get their hands on.
What I really like is it not only focuses on the actual filmed animation but they also have spotlights on the working side of animation. Concept sketches, how to's, etc....all from the classic masters of animation.
Anyways this is a pretty awesome tutorial on how-to draw 40ish animals. Very cool stuff.
