In North America , species such as broad-winged hawks and Swainson's hawks are known for their huge numbers (often called "kettles") while passing over major migratory flyways in the fall.

[11] Hawks also have relatively high visual acuity – the distance at which they can resolve an image – with red-tailed hawks reported to have 16.8 cycles per degree. [12]
[9] [10] B. j. calurus reaches its northern limits as a breeder in north-central British Columbia, much of the western part of the Yukon, interior Alaska and, near Inuvik in the Northwest Territories, the latter being the northernmost breeding range of the red-tailed hawk species.
This is a large-bodied, relatively heavy race, but differs from more westerly hawks in having a relatively smaller wing area. Based on linear dimensions, this subspecies shows the most size variation and, unlike the red-tailed hawk species overall, size variation seems to fall within Bergmann's rule as northern birds average larger than southern ones.
Red-Tailed Hawk. Extremely common in North America, the red-tailed hawk is often sighted soaring in circles overhead. As Wilson notes, smaller birds will attack and annoy red-tails, representing ...
The Jamaican red-tailed hawk (Buteo jamaicensis jamaicensis) is the nominate subspecies of the red-tailed hawk (Buteo jamaicensis), a bird of prey of North America.
