Chances are you have seen this species before; this large hawk is one of the most widely distributed, numerous and commonly observed raptors in Canada. With a wingspan of up to 1.4m (58”) the Red-tailed Hawk is a highly variable buteo; soaring hawks that have wide tails and long, broad wings. Circling high up in the air, the Red-tailed Hawk can see mice scurrying about on the ground from 30 m (100ft) up .
This particular hawk in the photo appears to have done just that; he saw a mouse and then caught it, bringing the unfortunate rodent away to eat it, flying right over my head in the process of carrying off the mouse.
As mentioned before, the Red-tailed Hawk is a highly variable hawk with at least 14 recognized subspecies; ranging from the dark ‘Harlan’s Hawk’ to the ‘Krider’s Hawk’, a very pale subspecies of the Red-tailed Hawk.
Red-tailed Hawks love woodlands near open country; therefore, their habitat is diverse and they can be seen almost anywhere in Calgary. In summer, we tend to see light-colored morphs of the Western calurus the most and in migration and winter, we usually see dark morph ‘Harlan’s Hawks’. Also, in the southern part of Alberta, we have some krider’s Red-tailed Hawks. However, no matter what subspecies you see, they are still very impressive, especially when you get a good look at those talons!
