The adult peregrine has bluish gray wings, a pale underbelly, and a black head.
As with other birds of flight, the falcon is designed with hollow bones, a lightweight beak, and air sacs that connect to the airway. These design features along with its feathers and wing structure make it a capable flyer. The peregrine falcon may teach its young to hunt by dropping dead prey to its flying young who then must grasp it while in flight. This was not part of their behavior until after the Fall of man.
