According to Handbook of North American Birds (vol. 5) (ed. R. S. Palmer, Yale Univ. Press, 1988) borealis, breeds e. N.A., s. to peninsular Fla. calurus, B. C. & Alta. s. to w. Neb, and into Mex (Chihuahua, Sonora. B. Cal.) alascensis, Alaska s. to Vancouver I. umbrinus, s. 3/5 of peninsular Fla., and Bahamas (?) fuertesi, Kans., Mo., s. through e. Tex to Mex. (Nuevo Leon; Chihuahua) solitudinis, Cuba & Isle of Pines jamaicensis, Jamaica (why not?), Hispaniola, P. Rico hadropus, highlands of Mex. (Jalisco s. to Oaxaca) kemsiesi, Chiapas, Guatemala, Honduras, ElCalvador, n. Nicaragua. costaricensis, Costa Rica (you guessed it!) & n. Panama fumosus, Tres Maris Is, off Nayarit, Mex. socorroensis, Socorro Is., off tip of Baja Cal., Mex. Interestingly, "Krider's" and "Harlan's" hawks (red-tails., s.l.) are not considered to be subspecies by Palmer, but rather color variants. Harlan's breed in Alaska and Yukon, and hence are probabaly alascensis/calurus; Krider's breed (maybe) in s. Canada (w. Ontario to Alta., and Minn, w. Neb, Colo., Wy, and Mont. -- i.e. a part of calurus. Hope this is of some help, and not to tedious for most of the readers. -- Name: Jim Rising Mail: Dept. Zoology, Univ.
