Red-tailed Hawk is the most common Buteo or broad-winged type of raptor in Colorado and on the Chico where it is a resident. In spring and fall, the common light morph types are joined by migrant and/or wintering subspecies of Red-tailed Hawk that could be any one of the following types, Harlan’s, Krider’s, Eastern, rufous morph, dark morph Western. They all look different and have variable coloration, but with a good photograph the subspecies or color morph can often be determined. Yesterday, this Western dark morph Red-tailed Hawk was circling over the banding station, gaining altitude for its continued journey south. Notice the dark brown head, breast, and belly with the dark brown extending out on the underwings, the dark subterminal tail band and the even width of the dark tail bands.
