Here's my bird animation so far. I might add some colour to make it really stand out. The animation seems okay, but I think there's a few lines that need correcting.

Great ideas - here's a small edit.

Good wings animation, but the chest appears to be shifted to the left. Legs are hanging like the bird prepares to land or they are just broken. Tail could use some work too as doesn't correspond to your chosen angle of view, and looks a bit puny. The beak has some unusual anatomy, which seems implies the bird sticks it inside some tight holes or uses it to do precise work like a hummingbird. If that is bird of prey, it will have a hooked nose, which is used to tear apart poor victims.
