Dark morph adult:

* Rare breeder in Alberta and rare migrant in West and Midwest

Similar species:

Red-shouldered Hawk is similar in adult plumage but has reddish shoulders, a pale crescent in the wings, lacks the distinct black border to the trailing edge of the wing, and the white bands on the tail are much narrower than the black bands. Immatures can be distinguished by shape and crescent-shaped pale window in outer primaries. Dark morph Swainson's Hawk has pale undertail coverts. Other dark buteos are much larger with much broader wings (Red-tailed, Rough-legged, and Ferruginous). Immature dark morph Short-tailed Hawk has darker secondaries that contrast with the pale primaries and does not overlap with the range of the dark morph Broad-winged Hawk.
