Notice the difference in the wings,, the more round wings makes it easier for the hawk to maneuver in and around trees and branches and turn on a dime. The hawk is much more suited for hunting low among trees. The falcons has more straight and the wing comes to a point,, which is built for speed!! Kinda of like fighter jets,, not sure what each jets are called,, but the work on the same principals. Some fighter jets can pull their wings in and out for just that purpose.
