advice/ tutorials on animating a bird images wings?

My next task will involve animating the wings using information from a still image. In other words, I have a still image of a robin and I want to make its wings move realistically (or as real as possible). Tutorials/ instructions regarding this would be appreciated. Thanks, Jon

Is this an American Red-Breasted Robin or a European "robin"? Their wing rythms and flight patterns are quite different.

I can't contribute any information regarding the authenticity of the wing flap of an American Robin, however there are several tutorials on-line about animating butterfly wings.

The method requires a minimum of 3 parts for the animation: body, left and right wing.

Make all 3 layers 3D.

Move the anchor points of each wing to the appropriate edge.

Animate a single wing's Y Rotation with the following expression: 60*Math.sin(10*time)

The numbers refer to amplitude (60) or the height of travel of the wing, the other number is the frequency of the wing flap.

Use the pickwhip to tie the Y Rotation of the other wing to the Y Rotation of the animated wing and add a minus sign in front of the expression so it reads something like this:

-thisComp.layer("right wing.psd").rotationY

Now parent both wings to the body and you're done.

To control the wing flap you can use expression sliders for amplitude and frequency rather than hard coded numbers.

I usually cut up the birds wings in 2/3 sectionsand parent them together.
Then animate rotation by hand.
Wasn't going for realism though.
