The Four Keys to ID

  • Size & Shape

    Rough-legged Hawks are fairly large hawks with broad wings that, compared to other Buteo hawks, are fairly long and narrow. The tail is also longer than in many other buteos. The wingtips are broad and often swept back slightly from the wrist, giving a hint of an M shape to the wing. The bill is fairly small.

    Relative Size

    Larger than an American Crow; slightly smaller and less bulky than a Red-tailed Hawk.
