Red-tailed Hawk Identification

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.

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.
