You really need to be in its presence to appreciate how big this Old World bird of prey is. Its body can be nearly 4 feet long, and it can have a 9.5-foot wingspan. Some people think it’s indeed the biggest bird of prey on earth, even bigger than a condor. That’s controversial, but there’s no doubt that this Eurasian vulture is one of the biggest flying birds in the world.

Scientific Name
The vulture’s scientific name is Aegypius monachus. Aegypius simply means “vulture or vulture-like bird” in Greek. Monachus is ancient Greek for “single” or “solitary” and gives the vulture its other name of “monk vulture.” Cinereous comes from the Latin for “ash-colored,” which is cinereus.
This differentiates Aegypius monachus, which is sometimes called the black vulture, from the much smaller North American black vulture, Coragyps atratus. There is only one species of cinereous vulture.
Evolution and Origins
In the past, vultures were once thought to have evolved only once among extant diurnal birds of prey. Now, New World vultures are classified as ancestrally related to, or closely related to, storks. Meanwhile, Old World vultures are more definitively linked to raptors or birds of prey.
Cinereous vultures have robust hooked beaks that are specialized for ripping apart portions of flesh from carcasses. They possess a third eyelid that shields their eyes from blood and tissue. While a diet of deceased creatures might seem unpalatable, vultures effectively engage in recycling by using carrion as sustenance.
Old World vultures are related to hawks and eagles in a group. Some experts say New World vultures are in their own group. This separation — vultures versus hawks — occurred over 50 million years ago, as shown by DNA evidence.
Appearance

This enormous bird can grow to between 43 and 47.24 inches in length, weigh up to 31 pounds, and have a nearly 10-foot wingspan. Its feathers are black or brown, its eyes are large and brown, and its powerful hooked beak is black. Unlike many other vultures, its head is feathered, but the feathers are small.
The bird’s legs are gray or cream-colored when it is an adult and pink when it’s a juvenile, as is its beak. Females are a bit bigger and heavier than males, which is often the case with accipitrids.
Behavior
Cinereous vultures are solitary, which, along with the tonsure-like ruff of feathers around their neck, gives them the name “monk vulture.”
They do not even congregate in great numbers at a food site, and there are rarely more than a dozen or so birds at what ornithologists call a “wake.” While feeding, they dominate all the other scavengers who want to get a piece of the carcass, including foxes, and can behave aggressively toward them.
They don’t migrate, but they will fly for miles to find food, then return to their usual roosts at night. They are usually silent, like most vultures, but vocalize in mewls, grunts, and roars during the mating season.

Cinereous Vulture Migration Pattern and Timing
These Eurasian vultures don’t migrate but have been known to fly as much as 46.6 miles from their roosts in search of food.
Where To Find Them
The cinereous vulture is found in countries in Eurasia such as Tajikistan and Kyrgyzstan. Other places where the vulture is found include mainland China, Afghanistan and Pakistan, Iran, India, and the Koreas. It’s also found in European countries such as Spain, Greece, and Bulgaria. They prefer habitats that are mountainous, open, or semi-open, where it is easy to spot carcasses from the air.
Cinereous Vulture Nests

As the vulture is a big bird, it builds a big nest, usually in an older tree or at the edge of a cliff. Both parents help build the nest, which can be nearly 7 feet across and nearly 10 feet deep. Because a monogamous pair uses the same nest year after year, the nest can increase in size. It is made out of sticks, twigs, branches, and sometimes trash, and over the years can be embellished, if that’s the word, with the hides of animals and dung. Unlike a lot of birds, cinereous vultures don’t appear to clean the nest while they’re raising their chick.
Diet
The vulture is mostly a scavenger that eats a variety of carcasses, including those of yaks, wild boars, chickens, deer, cattle, gazelles, marmots, rabbits, foxes, and humans. Once in a while, it will take live prey, and this includes the usually sickly young of cattle, yaks, sheep, pigs, and dogs. It sometimes eats lizards and insects and raids the nests of waterfowl such as swans or geese, and is believed to hunt certain species of antelopes such as the saiga.
Predators and Threats

Like the lappet-faced vulture of Africa, the cinereous vulture’s bill is powerful enough to tear open the toughest hides.

The only real predator for a bird this large and powerful is a human. Humans inadvertently kill the vulture by poisoning carcasses. The poison is meant for animals considered to be vermin, such as jackals and foxes. The vulture is also hunted for sport.
Reproduction, Babies, and Lifespan
Cinereous vultures are monogamous and mate for life. There’s only one breeding season per year, and it occurs in October and November. The female usually lays only one egg, and two eggs are unusual. Both parents build the nest, incubate the egg, and feed the chick.
The egg takes between 50 and 55 days to hatch, and the chick is covered with grayish down that eventually turns white before the feathers come in. Parents still take care of it for as long as seven and a half months, which is about two months after it has fledged. The chick will be ready to breed when it’s between four and five years old and can have a lifespan of as long as 40 years.
Population
The population of the cinereous vulture is between 16,800 and 22,800 individuals. Overall, its numbers are declining, and its conservation status is near threatened.

They can live a long time for a bird. Their lifespan ranges between 28 and 40 years.
How high can a cinereous vulture fly?
The heights this vulture can achieve are impressive. At least one was found at 22,870 feet around Mount Everest.
Is the cinereous vulture the largest vulture in the world?
Whether the cinereous vulture is the largest vulture in the world is uncertain, and many people believe that the Andean condor still has an edge. But it remains an eye-popping large bird.
