What's the difference between buzzards and vultures?
Physical Differences in Vultures and Buzzards Buzzards do not have bald heads, but vultures are prominent for their bald heads. Buzzards have strong beaks and talons to enable them to kill their prey and feast on them. Vultures on the other hand rarely kill their prey. Therefore, their beaks are fairly weak.
Will a vulture eat a dead vulture?
The flesh of an herbivore is much tastier. In short, turkey vultures will often bypass carcasses of cats, dogs, and coyotes. They will, however, eat such carcasses in the absence of more desirable food. Therefore, since vultures are not herbivores, they'll only eat a dead vulture if they're really hungry.
Do birds pee?
The answer lies in the fact that birds, unlike mammals, don't produce urine. Instead they excrete nitrogenous wastes in the form of uric acid, which emerges as a white paste. And uric acid doesn't dissolve in water easily.

What is the difference between a Black Vulture and a turkey vulture?
Whereas Turkey Vultures are lanky birds with teetering flight, Black Vultures are compact birds with broad wings, short tails, and powerful wingbeats. The two species often associate: the Black Vulture makes up for its poor sense of smell by following Turkey Vultures to carcasses.

First, vultures' taste for rotting flesh serves an important purpose of preventing the spread of diseases and bacteria. They aren't alone in their tendencies to puke on threatening passersby, either; stately herons, gulls and terns also rely on the vomit defense.
Why do vultures pee on themselves?
Vultures also urinate on themselves to keep comfortable and disease-free. As the urine evaporates, it cools the vulture's body in the same way sweat works on humans. The acid in the urine simultaneously destroys harmful pathogens from their last dinner.
How many species of vultures are there in the world?
The 12 existing species of Old World vultures are related to hawks and eagles and build nests out of sticks. The Western Hemisphere is home to seven species of New World vultures.

Vultures have relatively bare heads and often bare necks so that when they feed on rotting carcasses, bacteria and other parasites cannot burrow into thick feathers to cause infections. This allows the birds to stay healthier while feeding on material that would easily infect other animals.

Why do vultures stick their necks out?
They found that on hot days, the vultures tended to stick their necks out, and in cold weather, they tucked their heads underneath their wings. The scientists concluded that the birds’ bare skin helped them regulate their body temperatures because the skin rapidly loses heat. The trick may come in handy since many vultures have to deal with extreme daily temperature variation in their habitats.

What did John James Audubon believe about vultures?
In 1826, John James Audubon challenged the prevailing belief that all vultures had an extraordinary sense of smell. Audubon’s field experiments with birds he believed to be turkey vultures convinced him that the birds used sight to track down their food. Divided over this issue, ornithologists broke off into rival factions: “Nosarians” still believed that vultures were scent-driven animals while “anti-nosarians” agreed with Audubon’s thesis. Both sides were partially right. Most Old World vultures are indeed guided by vision—as is the North American black vulture, which is probably the species that Audubon looked at in his experiments. But the turkey vulture has a phenomenal sense of smell, allowing it to zero in on carcasses from thousands of feet overhead—a nice compliment to the animal’s keen eyesight.
What do Egyptian vultures do?
Egyptian vultures can use tools. With round-edged stones, the Egyptian vulture ( Neophron percnopterus) hammers away at ostrich eggs until they crack open.

Why are black vultures exploiting urbanizing landscapes?
Trouble is (from the disgusted-human perspective), black vultures are exploiting urbanizing landscapes, thanks to an increase in food sources such as roadkill and, from all indications, a warmer environment provided by growing acres of asphalt and concrete . In fact, the same things that draw new human residents to a burgeoning area are high on a vulture’s relocation wish list: Great roads. Warm climate. Lots of open space but still convenient to good shopping.
What is the most important factor that affects the range of black vultures?
But others are far more convinced. “Climatic change is the most important factor affecting black vulture range changes,” says The Peregrine Fund’s Lloyd F. Kiff. “This is a species where there is a direct correlation to temperature. The northern range limit is set by a thermal line that allows carcasses to stay unfrozen. And vultures are like people: They are going to take advantage of every opportunity presented to them.”
What did Charles Darwin say about vultures?
Early taboos against touching dead bodies put vultures in a singular category of grotesquery, and Old Testament texts considered them “an abomination among the birds.” Charles Darwin, of all people, cheerlessly ranted that vultures were “disgusting” and “wallow in putridity.” He might have felt at home in Leesburg.

Why do vultures fly in circles?
When you see vultures circling above, they are not loitering in the sky waiting for a potential prey item to die. Vultures do use thermals, or naturally occurring rising columns of hot air, to assist in soaring flight. In this way they are able to conserve energy as they search for carrion.
Is a vulture a buzzard?
The short answer is no. Technically speaking, vultures and buzzards belong to very different families of birds. Vultures are large carrion-eating birds. Buzzards are buteos -- North America's Red-tailed Hawk ( Buteo jamaicensis) and Europe's Common Buzzard ( Buteo buteo) are both part of this family. North Americans call buteos "hawks", while the rest of the world may know this same family of birds as "buzzards". In North America, a common colloquial name for vulture is buzzard. Early settlers may have called all of the large birds they saw "buzzards" -- and this common name stuck to the vultures.

Groups of vultures spiraling upward to gain altitude are called kettles. When they are eating as a group, we call that a wake. When they roost together, they are called committees. They form communal roosts (ranging in size from a few to several thousand birds) which facilitate group foraging and social interactions. If you ever notice the roost in a committee, the one at the top is probably the matriarch/patriarch.
