Cooper's Hawks live in dense evergreen and deciduous forests throughout southern Canada and the United States. It was named in 1828 after the American zoologist William Cooper, who collected the specimens that were used to describe the species. It is also called Chicken Hawk or Hen Hawk, as these birds can be a problem around poultry farms where they may help themselves to unwary chickens. These little daredevils will dash through dense vegetation and crowded trees while hunting to catch birds, but this is a rather dangerous lifestyle. A study found that 23 percent of all Cooper's Hawks examined had healed fractures in the bones of the chest! Cooper's Hawk is the answer to the last Spot the Birdorable.
