Turkey Vulture

The Turkey Vulture is also known in North America as the Turkey Buzzard, or sometimes just Buzzard. It is found from southern Canada to the tip of South America. 

It is a fairly large bird with a wingspan of up to 6 feet, and can sometimes be mistaken for an eagle or osprey. These vultures are most commonly seen while driving on the open road and typically fly with their wings raised in a “V” while making wobbly circles.

3 Amazing Turkey Vulture Facts

• Not Cousins: Turkey Vultures belong to the “New World” group of Vultures. While they look similar to the “Old World” group of Vultures in Europe, they are not closely related. They evolved separately over time to develop many of the same characteristics in a process called convergent evolution.
• Strong Stomachs: A Turkey Vulture’s stomach acid is very strong so that it can digest rotting, diseased meat without harm. They also use strong acids and rancid meals as a defense mechanism.  When a threat approaches, they regurgitate the contents of their stomach. The strong acid and putrid smell will deter the threat from continuing closer.
• Aerial Sharks: Turkey Vultures use their keen sense of smell to find decaying carcasses that are their main food source. The part of their brain used for smell is particularly large compared to other birds, and they detect odors that are as low as a few parts per trillion in the air. 

Where to Find Turkey Vultures

Turkey Vultures are found year-round in southern North America, Central America, and South America.  They can also be found in the northern United States and southern Canada in the summer months. 

Turkey Vultures are scavengers, so they are most frequently found near humans. They are the easiest to find while driving around open areas near woodlands, as they frequently consume the remains of “roadkill,” small animals that have been hit and killed by vehicles. 

Turkey Vultures can be noticed in the sky as a group of large birds with wings in an upswept “V” and flying wobbling in circles. They use thermal updrafts to stay in the air while they use their keen sense of eyesight and smell to find their next meal.

Turkey Vulture Nests

Turkey Vultures don’t build a full “bird’s nest” that is typical of other smaller birds. They will find isolated areas that are cooler than the surroundings. Areas could include ledges or rock crevices in north-facing cliffs, caves, thickets, hollow logs, fallen trees, or even abandoned buildings. 

They may arrange vegetation and leaves, scrape a spot in the soil or log, and move smaller rocks or debris. While they often are found near humans, they prefer to nest away from the activity to avoid disturbance. 

Sometimes, they may reuse the same nest for many years.

Turkey Vulture Scientific name

The Turkey Vulture has the scientific name Cathartes aura. Its class is Aves and belongs to the Cathartidae family. 

The common name “Turkey” comes from its resemblance to the adult’s bald red head and dark plumage of a male wild Turkey. “Vulture” comes from the Latin word vulturus, meaning “tearer,” in reference to how it eats the carcasses of deceased animals.

There are five subspecies of Turkey Vulture:

• Cathartes aura aura is the nominate species and is mainly found in Mexico and South America
• Cathartes aura jota is known as the Chilean turkey vulture
• Cathartes aura meridionalis is known as the Western turkey vulture
• Cathartes aura ruficollis is known as the Tropical turkey vulture
• Cathartes aura septentrionalis is known as the Eastern turkey vulture

Turkey Vulture Size, Appearance, and Behavior

Turkey Vultures are large birds with up to a 6-foot wingspan, a length of 32 inches, and weighing up to 5.3 pounds. Their outer feathers are mostly brownish-black, with the feathers on their wings typically white/gray in color. When in flight, the wings appear to have “fingers” at the ends. Their head is small and resembles a turkey’s, bald with no feathers, and red in color, and their hooked beak is short and white/gray in color.

A Turkey Vulture’s feet are long and typical of a bird of this size. The talons appear similar to an eagle or hawk, but are not very powerful and not well-suited to grasp objects or prey.

On the ground, they are awkward and have a strange, ungainly hopping walk. It takes a lot of effort to take flight, so they are slow to take flight unless threatened. During the flight, they normally travel in groups and can sometimes be seen roosting in the hundreds.

Turkey Vulture Diet

Turkey Vultures are scavengers and typically eat carrion (decaying flesh of animals). They rarely attack anything living. Their keen sense of smell allows them to detect very small amounts of the odor of decaying flesh in the air as they fly. 

They will typically fly in smaller and smaller circles until they zero in on the carcass. Their stomach has a high level of acid, and they can digest meat with high levels of bacteria and disease without harm to themselves.

Turkey Vulture Predators, Threats, and Conservation Status

Turkey Vultures have few natural predators, and those that are predators do not take them very often. Typical predators are golden eagles, bald eagles, red-tailed hawks, and great-horned owls. These birds may prey on older adults who are sick and/or slow. 

Foxes and dogs can sneak up on them while feeding, but it is rare.

The largest threat to Turkey Vultures is eating the remains of animals that hunters have shot with lead.  They consume the lead while feeding, and eventually, at high enough levels, they die from lead poisoning.

Humans may also trap or kill them from the false belief that they spread disease. However, Turkey Vultures help the environment by removing rotting carcasses that may otherwise spread disease.

Reproduction, Young, and Molting

Turkey Vultures lay their eggs beginning in the spring through early summer. This depends on the region and latitude of their location. In cooler regions, they start later in the spring through late summer. 

Typically, two eggs are laid, sometimes only one, and rarely three. The eggs are white in color with dark spots around the larger diameter. The young typically hatch after 30 to 40 days. 

The young are helpless when they hatch, and the parents care for them for 10 to 12 weeks. At about the same time, the young fledge and can fly independently. The family will remain together until fall.

Population

Current global population estimates range between 18-28 million.  The population has undergone a significant increase over the past 40 years, particularly in North America, and is currently considered stable or increasing. The conservation status is of least concern due to the lack of many natural predators.
