Turkey Vulture (Cathartes aura): Facts, Smell and Habitat

Appearance: how to recognize a turkey vulture

Up close, an adult turkey vulture is unmistakable. The body and wings are brownish black, the head is small, featherless and red, and the short, hooked bill is pale ivory. The legs and feet are pinkish but often look white because the bird streaks them with its own droppings to cool down, a habit called urohidrosis. Males and females look alike.

The common name comes from the adult’s resemblance to a male wild turkey, with its bare red head and dark plumage. Young birds have gray-black heads and dark bills, and gain the red skin gradually over their first couple of years.

In the sky, the turkey vulture is easiest to identify by its flight. From below, the flight feathers look silvery gray against the black wing linings, giving a two-toned look. The bird holds its long wings raised in a shallow V, called a dihedral, and rocks or teeters from side to side as it glides, rarely flapping. The similar black vulture has shorter, broader wings with white patches near the tips, a short tail and a gray-black head, and flaps more often.

Size: how big is a turkey vulture?

The turkey vulture is a large bird, but much of its size is wing. Its body is light for its span, which is ideal for long, cheap soaring flights.

Birds in the north of the range average larger than those in the tropics. Turkey vultures in Florida, for example, average about 2 kg (4.4 lb), while birds measured in Venezuela averaged well under 1.5 kg (3.3 lb). Both sexes are close in size. For comparison, the Andean condor, a giant relative in the same family, can weigh more than five times as much.

Habitat and range

Turkey vultures live in an enormous range, from southern Canada across the United States, Mexico, Central America and the Caribbean to Tierra del Fuego at the southern tip of South America. With an estimated population of around 18 million birds, they rival the black vulture as the most abundant vulture on Earth.

They prefer open and semi-open country where they can search the ground from the air: pastures, farmland, woodland edges, deserts, shrubland, coasts and highway verges. Patches of woodland, cliffs or rocky outcrops nearby provide safe places to nest and roost. They tend to avoid large, unbroken forests, where carcasses are hidden and it is hard to take off.

Birds in the southern United States and the tropics are mostly resident. Those breeding in Canada and the northern states migrate in autumn, many of them as far as Central and South America, and return in late winter or early spring. Over the past century the species has spread north, becoming common in parts of New England and eastern Canada where it was once scarce.

Diet: how turkey vultures find food

The turkey vulture is a scavenger that feeds almost entirely on carrion, the bodies of animals that have already died. It eats mammals of every size, from mice to deer, as well as dead birds, reptiles, amphibians and fish washed up on shores. Roadkill is an important food source, which is why the birds are so often seen along highways. On rare occasions they take stranded fish, insects or rotting fruit.

What makes the turkey vulture special is its sense of smell. It has one of the largest olfactory regions, the brain area that processes smell, of any bird. Flying low over woods and fields, it can detect ethyl mercaptan, a gas released when a dead animal begins to decay, and find carcasses hidden beneath a forest canopy where they could never be spotted from the air.

Turkey vultures prefer fairly fresh meat. Their weak bills struggle with the tough hide of large animals, so they often wait for a carcass to soften or for stronger scavengers to open it. King vultures, condors and black vultures, which have a poorer sense of smell, often follow turkey vultures to food and then push them aside. Turkey vultures also have weak, flat feet with blunt talons, so they cannot kill or carry prey the way hawks and eagles do.

Flight and soaring

Turkey vultures are masters of energy-saving flight. Instead of flapping, they ride thermals, columns of warm air rising from sun-heated ground, and the updrafts that form where wind strikes hills and ridges. Once airborne, a vulture can glide and circle for hours with only an occasional wingbeat.

Because thermals do not form until the ground warms up, turkey vultures are late risers. They often sit on their roost with wings spread in the morning sun and take to the air in mid-morning. Circling over one spot is usually a sign of a bird gaining height in a thermal, not of an animal about to die; the full explanation is in why do vultures circle?.

Taking off from the ground is hard work. A turkey vulture has to hop and flap heavily to get up, and a bird that has just eaten a big meal may have to empty its crop, the food storage pouch in its throat, before it can escape a threat.

Behavior and communal roosts

Turkey vultures are social at night and mostly solitary by day. They gather in communal roosts in tall dead trees, on transmission towers, water towers or rocky cliffs, sometimes in groups of several hundred and often together with black vultures. Some roosts are used for many years. In the morning the birds leave to search for food on their own, though they keep an eye on one another and quickly join a vulture that has found something.

At night a turkey vulture can lower its body temperature by about 6 °C (11 °F), saving energy in a kind of controlled mild hypothermia. In hot weather it cools down by excreting onto its legs, letting the evaporation chill the blood vessels in its bare skin. The bare head itself is part of the bird’s temperature control as well as being easier to keep clean, as explained in why are vultures bald?.

Lacking a syrinx, the voice organ of most birds, turkey vultures are almost silent. They hiss and grunt at rivals and intruders. Their main defense is famous: when disturbed at a nest or roost, they vomit up foul-smelling, half-digested meat. The smell drives off most predators, and the lighter load makes it easier to fly away.

Reproduction, life cycle and lifespan

Turkey vultures do not build nests. The female lays her eggs on bare ground or debris in a sheltered spot such as a cave, a crevice in a cliff, a hollow log or tree, a thicket, or an abandoned building. Pairs are believed to stay together for many years and may reuse good sites.

The usual clutch is two cream-colored eggs with brown blotches, occasionally one or three. Both parents incubate them for about 30–40 days. The chicks hatch helpless and covered in white down, and both adults feed them by regurgitation. Young turkey vultures make their first flights at about 9–10 weeks old, and families often stay together until autumn.

Little is known about the typical lifespan of wild turkey vultures. The oldest known wild bird, identified from a leg band, was almost 17 years old. In captivity they can live far longer: several individuals have passed 45 years, and a male hatched in 1974 was still alive at a wildlife center in California in 2025, at more than 50 years old.

Predators and threats

Adult turkey vultures have few natural predators. Great horned owls, golden eagles and bald eagles occasionally take young or adult birds, and raccoons and opossums can raid eggs and chicks. Most known deaths are caused by people, including collisions with vehicles and power lines and entanglement in fences.

Like condors and eagles, turkey vultures are at risk of lead poisoning when they eat carcasses or remains that contain fragments of lead ammunition. They can also be poisoned by eating animals killed with pesticides or veterinary drugs. In the mid-1900s, the insecticide DDT thinned the eggshells of turkey vultures as well as those of many birds of prey, such as the bald eagle.

Conservation status

The IUCN Red List classifies the turkey vulture as Least Concern, and its population is increasing. In the United States it is protected under the Migratory Bird Treaty Act of 1918, which makes it illegal to harm the birds or take their eggs or feathers without a permit; Canada and Mexico give similar protection.

The turkey vulture is doing far better than many Old World vultures in Africa and Asia, several of which are now Critically Endangered because of poisoning. Its success is partly linked to people: roads supply carrion, and the clearing of forests created the open country it likes.

Myths and facts

Myth: vultures circle over dying animals. Circling vultures are almost always riding thermals to gain height cheaply. They do watch the ground and each other for food, but they have no way of knowing an animal is about to die.

Myth: turkey vultures are related to turkeys or eagles. They are named only for their looks. New World vultures form their own family, Cathartidae, which also includes the condors, and are not closely related to the Old World vultures of Europe, Africa and Asia. The two groups look alike because they evolved for the same job, an example of convergent evolution.

Fact: vultures help keep the environment clean. By disposing of carcasses quickly, turkey vultures recycle nutrients and remove rotting meat that could spread disease. Their strongly acidic stomachs destroy many dangerous bacteria in the food they eat.

Relationship with people

Turkey vultures are a familiar sight across the Americas, wobbling over fields and highways or gathering in winter roosts in towns. Some communities celebrate their return in spring, and hawk-watching sites record huge numbers of them on migration. In some places large roosts on buildings or towers cause complaints about noise, smell and droppings, but the birds pose no danger to people.

For birdwatchers, the turkey vulture is one of the easiest large birds to spot. Look for a dark bird soaring on raised wings, rocking gently from side to side, on any warm day from mid-morning onward.
