Depth perception is evident when you look off in the distance and things that are farther away appear smaller than things that are closer. Raptors usually have excellent eyesight overall. It has been said that if an eagle could read, it could read a newspaper headline from 1 to 2 miles in the air. Talons are basically the sharp claws on a raptor. A very sharp, hooked bill.
All raptors have a bill that is extremely sharp.
This makes it easy for the bird to tear into the flesh of another animal and cut it into small pieces to feed its young or itself. Raptors are a very interesting type of bird, as well as one of the most noticeable because of their size. Go to the library or a large bookstore. I have found several good raptor books. There are also field guides devoted only to raptors.
