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.
