All About Birds says that Cooper’s Hawks (known as the Chicken Hawk in England) are among the bird world’s most skillful fliers, tearing through tree canopies in high speed pursuit of other birds. They have more information and hawk calls and offer some fun facts:
- Dashing through vegetation to catch birds is a dangerous lifestyle. In a study of more than 300 Cooper’s Hawk skeletons, 23 percent showed old, healed-over fractures in the bones of the chest.
- Once thought averse to towns and cities, Cooper’s Hawks are now fairly common urban and suburban birds.
- Life is tricky for male Cooper’s Hawks. As in most hawks, males are significantly smaller than their mates. The danger is that female Cooper’s Hawks specialize in eating medium-sized birds. Males tend to be submissive to females and to listen out for reassuring call notes the females make when they’re willing to be approached. Males build the nest, then provide nearly all the food to females and young over the next 90 days before the young fledge.
- The oldest known Cooper’s Hawk was 20 years, 4 months old. (and apparently good at either providing food or flying fast!)
