Rough-legged Hawks (Buteo lagopus) are winter visitors here in Bighorn Canyon. Their wingspan is a little over four feet and they are usually 19” long. They have two distinct color phases and much individual variation. Some have an almost entirely dark body and some have only the lower part of the body dark with the upper part being distinctly lighter in contrast. The fan shaped, white tail has a dark, wide band across the end.
