Play media Red-tailed hawk hovers in the wind The red-tailed hawk is a member of the subfamily Buteoninae which includes about 55 currently recognized species. Diverse in plumage appearance, habitat, prey and nesting preferences, buteonine hawks are nonetheless typically medium to large sized hawks with ample wings while some fossil forms are very large, larger than any eagle alive today.

Members of this genus are known as buzzards in Eurasia, but hawks in North America. The buzzards of Eurasia and Africa are mostly part of the genus Buteo, although two other small genera within the subfamily Buteoninae occur in Africa.

The rufous-tailed hawk, while comparatively little studied, is very similar to the red-tailed hawk, being about the same size in body mass and possessing the same wing structure, and having more or less parallel nesting and hunting habits.

Physically, however, rufous-tailed hawk adults do not attain a bright brick-red tail as do red-tailed hawks, instead retaining a dark brownish-cinnamon tail with many blackish crossbars similar to juvenile red-tailed hawks.

The common buzzard, in turn, is also part of a species complex with other Old World buzzards, namely the mountain buzzard Buteo oreophilusthe forest buzzard Buteo trizonatus and the Madagascar buzzard Buteo brachypterus.

El Yunque National ForestPuerto Rico holds some of the highest known density of red-tailed hawks anywhere. Additionally, males and females average The largest females from this race are reportedly smaller than almost all male red-tails from other races in Canada.

Immatures of this race are usually blackish-brown overall with a white throat and wide tail-bands, rather unlike calurus.

The race breeds below the Arctic unlike more western birds which can reach the sub-Arctic as breedersand is absent from all but the southernmost part of the Hudson Bay and roughly the northern third of both Quebec and Newfoundland.

The breeding range of borealis seems to include most of Texas perhaps excluding the western sectionsOklahomaKansas and Nebraska. Immature borealis tend to have dark spotting on leg feathers but otherwise average paler than immatures of most other races.

Birds of abieticola type are more heavily marked below than typical borealis and, thus borealis seem to correspond to Gloger's ruleas well. This plumage variation appears to be a regional adaptation to the denser boreal forest. The race may breed as far south as northwestern Sonora in Mexico.

Its eastern limits are reached around central Manitobawhile to the south the states of MontanaWyomingUtahNew Mexico and Colorado are mostly occupied by calurus. Dark morph calurus adults are typically all chocolate-brown above and below although sometimes variously even jet-black or with a bit of tawny feather edging below with a rufous-tail, which sometimes has heavy blackish crossbars but is usually similar to other red-tails.

Intermediate or rufous morphs are rich rufous on the breast, with a broad, solid chocolate-brown belly band and heavily barred thighs and crissum. Like dark morphs, rufous morph adults usually lack the incomplete V on the back, but sometimes rufous feathers can manifest one.

Adults may show nearly endless variation in coloring and many may combine several characteristics of the three main morphs. Dark morph juveniles are usually mostly dark brown but with extensive pale mottling on the back and occasional tawny-edge feathers on the underside and slightly broader bars on the tail than pale morph calurus.

Rufous morph immatures are more similar to pale morph ones but are considerably more heavily streaked almost everywhere below from the thighs to the upper chest. This is a relatively small race. This subspecies is dark brown above and heavily pigmented dorsally, the white of breast contrasting with a deep rufous abdominal band which contains black streaks and spots.

Meanwhile, the flanks, wing linings and sides are an unbarred deep rufous. In some birds, the rich rufous color continues to the underside.


The chest is much less heavily streaked than in northern migrants B. Unlike other Central American races of red-tailed hawk, there seems to be no dark morph in this subspecies.
