Biology

Diet

This species is a carrion feeder , eating almost any type of dead animal. It can be commonly seen on the roadside eating vehicle-killed animals. The Turkey Vulture uses both sight and scent to find its food. This species also creates large communal roosts, with many birds gathering in the same tree or group of trees in the evening.

Reproduction

The breeding season begins in March, peaks from April to May, and extends into June. This species will nest in a variety of habitats , but usually in wooded areas. Nest sites include the ground under a shrub , on a cliff , on a ledge, in a shed, or in a barn. No nest is built and eggs are usually laid on the ground, rocks, or other substrate. The female lays 1-3 (usually 2) eggs that she and the male incubate for 38-41 days. The young are semi-altricial and are cared for by the adults for 66-88 days after they hatch . For the first five days after they hatch, the young are brooded continuously by the adults

Clutch Size: 2 Length of Incubation : 38-41 days Days to Fledge : 66-88 Number of Broods: 1

Migration

Short distance migrant

Behavior

Though its dining habits are less than elegant, the vulture is an expert in using air currents and its physique to find carrion . It must search a great deal of territory to find a dead or dying creature for a meal . The vulture is too big to fly long distances efficiently by flapping its wings. Instead, it lets air currents and its large wingspan work for it. Rising columns of air, called thermals, are particularly useful. When one bird finds a good thermal and is climbing successfully, other birds often join, and soon the group can be seen circling around a common axis . It behooves the vulture to fly in steady circles of the smallest diameter, so it can stay near the center of the thermal core where the lift is the strongest. When a height of several hundred meters is attained, the vulture can leave the thermal and glide off, slowly descending , constantly searching the terrain. If a possible meal is sighted, the vulture can reach that point quickly by pouring its efforts into a steep dive. The steeper the angle , the faster the bird travels. He is often able to beat four-footed scavengers to the prey .[1]

Similar Species

[ Back to top ]

The most similar species to the Turkey Vulture is the Black Vulture. The Black Vulture has a black bald head. Most of the Black Vulture wing appears black, except a few of the outer flight feathers which create large white-appearing patches near the outer edges of the wings. The wings of the Black Vulture are shorter and broader, and the tail is also shorter.

The Black Vulture is also dark with an unfeathered head, but has a much differet shape in flight. It is short-winged, short-tailed, and intersperses glides on flat wings with quick, snappy wingbeats. Turkey Vultures lack the white patch at the wingtips and show contrast between paler flight feathers and darker coverts. Bald and Golden eagles are both superficially similar, but fly on flat wings, have feathered heads, and do not have contrastingly gray flight feathers. The Zone-tailed Hawk in the Southwest has a similar shape and flight style, but has a feathered head and white bands on a black tail.
