[175] Other than wild turkeys, other larger birds occasionally lose young to red-tails such as trumpeter swans (Cygnus buccinator), sandhill cranes (Grus canadensis) and great blue herons (Ardea herodias). [47] In perched individuals, even as silhouettes, the shape of large Buteos may be distinctive, such as the wingtips overhanging the tail in several other species, but not in red-tails. [126][136] Another member of the Lagomorpha order has been found in the diet, the much smaller American pika (Ochotona princeps), at 150 g (5.3 oz), but is not quantitatively common in the foods of the species so far as is known. [4] Where they overlap, the hawk species may adjust their daily routine to minimize contact, which tends to be costly of time and energy and may cause the hawks to abandon their nests for long stretches of time, which in turn leaves their young vulnerable to predation. Red-tailed hawks have an advantage in staple prey flexibility as aforementioned, while great horned owl populations can be stressed when preferred prey is scarce, especially when they rely on leporids such as hares and jackrabbits. [63][199] One other larger species, the rough-legged buzzard, mostly nests far north of the breeding range of red-tailed hawks. [171] Also, a non-native Egyptian goose (Alopochen aegyptiaca), in which adults average 1,762 g (3.885 lb), was killed by a red-tail in Texas. [9][98][123][211] The mean initiation of clutches may bump weeks later if 10 cm (3.9 in) or more of snow is still on the ground in Wisconsin during March. They vary from medium-sized to large birds and most have an upright posture and strong, short, hooked bills. [250][251] Other than large birds of prey, extensive records of predation on red-tailed hawks is surprisingly poor, in spite of several populations recording nestlings and eggs disappearing through presumed acts of natural predation. In some cases, such as near urban regions, immatures may be driven to a small pockets of urban vegetation with less tree cover and limited food resources. [9][63][229] The nest is constructed of twigs, and lined with bark, pine needles, corn cobs, husks, stalks, aspen catkins, or other plant lining matter. [203][204][205] Of these three Buteo species, the Swainson's hawk is most dissimilar, being a long-distance migrant which travels to South America each winter and, for much of the year, prefers to prey on insects (except for during breeding, when more nutritious food such as ground squirrels are mainly fed to the young). [9][98][117] In Wisconsin mean ranges for males range from 1.17 to 3.9 km2 (0.45 to 1.51 sq mi) in males and from 0.85 to 1.67 km2 (0.33 to 0.64 sq mi) in females, respectively in summer and winter. In immature red-tailed hawks of all morphs, the tail is a light brown above with numerous small dark brown bars of roughly equal width, but these tend to be much broader on dark morph birds. [226][227] Most predation by the owls on the hawks is directed at nestlings at the point where the red-tails' nestlings are old enough that the parents no longer roost around the nest at night. [172] There are several known instances of predation on adult greater sage grouse (Centrocercus urophasianus), although mainly females are reported taken, these averaging 1,200 to 1,745 g (2.646 to 3.847 lb) depending on region. On the other hand, red-tailed hawks are rarely (if ever) a threat to the great horned owl. The following species of accipitrid have been known to fall prey to red-tailed hawks, potentially including nestlings, fledglings, immatures and/or adults: swallow-tailed kite (Elanoides forficatus),[236] Mississippi kite (Ictinia mississippiensis),[237] white-tailed kite (Elanus leucurus),[238] northern harrier (Circus hudsonius),[84] sharp-shinned hawk (Accipiter striatus),[239] Cooper's hawk (Accipiter cooperii),[240] goshawks,[220] gray hawk (Buteo plagiatus),[241] red-shouldered hawk[242] and broad-winged hawk (Buteo platypterus).
