Widespread and common. Apparently has increased in some areas since the 1960s, and numbers now stable or still increasing. In several regions of North America, Red-tailed Hawks are adapting to nesting in cities. Open country, woodlands, prairie groves, mountains, plains, roadsides. Found in any kind of terrain that provides both some open ground for hunting and some high perches. Habitats may include everything from woodland with scattered clearings to open grassland or desert with a few trees or utility poles.
This is the most widespread and familiar large hawk in North America, bulky and broad-winged, designed for effortless soaring. An inhabitant of open country, it is commonly seen perched on roadside poles or sailing over fields and woods. Although adults usually can be recognized by the trademark reddish-brown tail, the rest of their plumage can be quite variable, especially west of the Mississippi: Western Red-tails can range from blackish to rufous-brown to nearly white. Does most hunting by watching from a high perch, then swooping down to capture prey in its talons. Also hunts by flying over fields, watching for prey below. Small prey carried to perch, large prey often partly eaten on ground. In courtship, male and female soar in high circles, with shrill cries. Male may fly high and then dive repeatedly in spectacular maneuvers; may catch prey and pass it to female in flight. Nest site is variable. Usually in tree, up to 120' above ground; nest tree often taller than surrounding trees. Also nests on cliff ledges, among arms of giant cactus, or on artificial structures such as towers or buildings. Nest (built by both sexes) a bulky bowl of sticks, lined with finer materials, often with leafy green branches added.
