beak
The shape of the beak is related to what the bird eats: Chickens have a short hard beak for picking up and cracking seeds, ducks have a flat beak for scooping up things out of the water, and eagles have a hooked beak for tearing meat. The feet indicate how the birds live. The chicken's feet are for walking and scratching the ground, the eagle's feet are talons for grasping, and the duck's feet are webbed for swimming. The sternum structure is related to flying ability. A chicken's sternum is not as large as that of an eagle or a duck, because a chicken's wings are not large, and it doesn't fly very well. I would think an eagle's sternum is proportionally larger than a duck's, because an eagle is larger and a better flyer- it must lift its prey.
short and heavy
Male ducks have a curled feather on their tail while the females do not.
take, for an example, a duck. This is a 3d shape because it has three dimensions. Compare this to a square, which is 2d. the difference is that the duck has a beak, and the square does not.
