called the Sparrow Hawk. Falcons have a streamlined body, long, pointed wings and <br />long tails. A series of strong, rapid wing beats gives them extremely fast flight in <br />open country, and their swiftness allows them to overtake and capture other birds on <br />the wing. <br />The American Kestrel is the smallest of our hawks and feeds mainly on mice and <br />insects. It is the only one of the falcons that hovers over its intended prey. Because <br />of its habitat and range, it is also the only Falcon or Accipiter that most people are <br />likely to see. <br />The Buteos are the largest of the hawks. They are the broad-winged, broad-tailed <br />soaring hawks that are more readily seen because of their habit of circling high in the <br />air or perching in dead trees or on telephone poles along the road. They include the <br />Red-tailed, the Red-shouldered, the Swainson's, the Rough-legged and the <br />Ferruginous hawks. <br />Description <br />The Red-tail is the largest hawk, usually weighing between 2 and 4 pounds. As with <br />most raptors, the female is nearly 1/3 larger than the male and may have a wing <br />span of 56 inches. This species shows a great deal of individual variation in plumage. <br />The adult has arufous-colored tail that may or may not have a black terminal bar. <br />Adults are dark brown on the back and the top of their wings. The underside of the <br />bird is usually light with a dark belly band, and a cinnamon wash on the neck and <br />chest.. Immatures resemble the adults except their tail is brown with dark bars; the <br />red- tail molts in during its second year. <br />The adult Red-tailed Hawk is easily identified, for when it leaves its perch on slow, <br />measured wing beats, or turns while soaring overhead, the broad, rounded tail <br />shows a rich, russet red, hence the name. Within its range, its frequent soaring and <br />loud voice are a good pointer. <br />Curious Facts <br />Hawks are carnivores (meat eaters) who belong to the category <br />of birds known as raptors. <br />The Red-tailed Hawk is the most common member of the <br />buzzard hawk family. <br />The eyesight of a hawk is 8 times as powerful as a human's. <br />Like all hawks, the Red-tailed Hawk's talons are its main <br />weapons. <br />The Red-tailed Hawk has hoarse and rasping 2- to3-second <br />scream that is most commonly heard while soaring. <br />85 to 90 % of the Red-tailed Hawk's diet is composed of small <br />rodents. <br />
