Turkey Vultures occur in a variety of open and forested habitats. Unlike Black Vultures, Turkey Vultures typically avoid urban and suburban areas. In North America, the species breeds in farmlands, rangelands, forests, and low-elevation mountains. Turkey Vultures do not build nests, but rather lay their eggs in dark recesses in ledges, caves, crevices, and hollow logs, as well as on the ground. Turkey Vultures also nest in the abandoned stick nests of birds, in mammal burrows, and in abandoned buildings. The species is monogamous, and evidence suggests that pairs remain together until one member dies. Existing pairs return to and reuse nesting sites year after year. For several days to several weeks prior to egg-laying, the pair spends time sitting together at the nest. Vultures perform aerial courtship displays during which one bird follows the other and precisely mimics the lead bird’s flight path. Flight displays are usually brief, although occasionally they are repeated for several hours. Although clutches can range in size from one to three eggs, Vultures generally lay two eggs. Both parents share the task of incubation, which lasts for about five weeks. Males and females also take turns brooding the young, which are brooded continually for the first five days. Thereafter, the parents spend less time brooding. Both parents feed the young by regurgitation, either directly into a begging nestling’s gaping mouth or on the ground next to the nestling. Young Vultures fledge at 60 to 80 days of age. For one to three weeks after their first flight, fledglings perch and roost at the nest site and continue to be fed by their parents. Thereafter fledglings slowly explore the area around the nest site, and by the time they are 12 weeks old, they have dispersed from the area.
