The Four Keys to ID

  • Size & Shape

    Red-tailed Hawks are large hawks with typical Buteo proportions: very broad, rounded wings and a short, wide tail. Large females seen from a distance might fool you into thinking you’re seeing an eagle. (Until an actual eagle comes along.)

    Relative Size

    The Red-tailed is the second-largest Buteo hawk in North America, after Ferruginous Hawk.

  • Most Red-tailed Hawks are rich brown above and pale below, with a streaked belly and, on the wing underside, a dark bar between shoulder and wrist. The tail is usually pale below and cinnamon-red above, though in young birds it’s brown and banded. “Dark-morph” birds are all chocolate-brown with a warm red tail. “Rufous-morph” birds are reddish-brown on the chest with a dark belly.

  • You’ll most likely see Red-tailed Hawks soaring in wide circles high over a field. When flapping, their wingbeats are heavy. In high winds they may face into the wind and hover without flapping, eyes fixed on the ground. They attack in a slow, controlled dive with legs outstretched – much different from a falcon’s stoop.

  • The Red-tailed Hawk is a bird of open country. Look for it along fields and perched on telephones poles, fenceposts, or trees standing alone or along edges of fields.

Regional Differences

Red-tailed Hawks have extremely variable plumage, and some of this variation is regional. A Great Plains race called "Krider's" hawk is pale, with a whitish head and washed-out pink in the tail. Light-morph western birds tend to be more streaky on the underparts than eastern Red-tails; south Texas forms are darker above, without the dark belly band most other Red-tails have. Dark-morph birds can occur anywhere but are more common in western North America - particularly in Alaska and northwest Canada, where the all-dark "Harlan's" race is common.
