If the feet are a little horny, the talons with dry and white feet are old birds, and the feet of young birds look black and dry. They are powerless, not claws, but like duck feet without webbed feet.

The body of a young bird is not as thin as the feathers of an adult bird. Adult birds' toenails are much longer, their mouths are even in color and sharp, and parrots' mouths are also long.
