Other names: Buzzard, hen hawk, mouse hawk, chicken hawk.
Hunting habits: Soars in sky watching for prey in open country, or probably more often watches for prey from a perch. Rodents are main prey–also grasshoppers, rabbits, moles, shrews, weasels, skunks (most birds have no sense of smell), porcupines, feral cats, many medium-sized and small birds, snakes, lizards, frogs, toads, salamanders, crayfish, small fish caught at the edge of the water, and large insects. Red-tailed Hawks have been killed when the rattlesnakes and weasels they caught fought back.
Migrating Habits: Like most buteos, Red-tailed Hawks are excellent soaring birds. They will take advantage of updrafts (especially thermals) to save energy while migrating. During peak migration dozens of them may be seen circling in kettles.
Nesting habits: Bulky stick nest, often decorated with sprigs of evergreens; sometimes nests on a cliff. Female incubates the 2-3 eggs for a month while the male brings her food on the nest. The young first fly when they are 6 or 7 weeks old.

Wingspan: 110-141 cm
