Jamaica (B. j. jamaicensis): this was the first described Red-tail Hawk (nominate species), hence the Latinized species name; jamaicensis. This sub-species occurs in the Northern West Indies (Jamaica, Hispaniola, and the Lesser Antilles), but not in the Bahamian or Cuban Islands.

Eastern North America (B. j. borealis): The Eastern sub-species breeds from Maine and Eastern Canada to Central Canada South to Northern Florida, and West to Eastern Texas and all the Great Plains states and Provinces East of the Rocky Mountains. Birds from the Far North will migrate South for the Winter, but Southern Birds may be year round residents. This Red-tailed hawk subspecies name "borealis" translates to "Northern".

Western North America (B. j. calurus): The Western sub-species breeds from Central Alaska and Western Canada South through The Western U.S. including all the Rocky Mountain States to Northern Mexico and Baja California. Their migration patterns are similar to Eastern Birds, with most Northern birds migrating South into Mexico and some Southern birds remain as year round residents.  The sub-specific name "calurus" translates to "beautiful tail".

Fuertes (B. j. fuertesi): The Fuertes sub-species breeds mainly in Oklahoma and West Texas South to Arizona and New Mexico and into Mexico. Most of these birds are year round residents.  The sub-specific name "fuertesi" is named after bird illustrator and artist Louis Agassiz Fuertes.
