Cinereous vulture

This is a very big bird.

It is a dark bird. It lives in the mountains. It eats things that are dead. This helps keep the land clean.

The bird has a bald head. It also has a neck of feathers. This looks like a monk's clothes. It can fly very high in the sky. One bird was seen near Mount Everest.

They build big nests in tall trees. Most mothers lay just one egg. These birds are very important to nature.

The cinereous vulture is a very large bird.

It is also called the monk vulture. This name comes from its neck feathers. They look like a monk's hood. This bird lives in many parts of Eurasia. It likes to live in mountains and hills.

These vultures are very important to nature. They eat carcasses, which are the bodies of dead animals. By doing this, they help stop the spread of disease. Their bodies have strong stomach acid. This helps them digest food safely. They can even fly very high. One bird was seen near Mount Everest. They can breathe well in the thin air.

Most cinereous vultures live alone or in pairs. They build huge nests in tall trees. These nests can be very big. A pair will use the same nest for many years. They usually lay just one egg. The egg is white with red or brown spots. It takes about 50 to 62 days to hatch.

The cinereous vulture is a huge bird of prey.

It is the largest member of its family in the Old World. People also call it the monk vulture. This name comes from its neck feathers. They look like a monk's hood or cowl. This bird is very important for the planet. It eats carcasses of dead animals. This job helps stop the spread of diseases.

This bird has a special way of staying healthy. Eating dead animals can expose a bird to many germs. To stay safe, the vulture uses strong stomach acid. This acid helps it digest carcasses safely. A 2015 study looked at the bird's entire genome. This is the map of its DNA. Scientists found special genetic traits in the bird. These traits help with breathing and immune defense. These systems work together to keep the bird safe.

Many names have been used for this bird over time. The name Aegypius comes from a Greek word for vulture. An ancient writer called it something between an eagle and a vulture. The name cinereous comes from a Latin word for ash-colored. This was used to tell it apart from American vultures. These American birds are much smaller. The cinereous vulture is also closely related to the lappet-faced vulture. They are part of the same large group of birds.

These vultures are among the heaviest flying birds.

A male can weigh 10 kilograms. A female can weigh up to 12 kilograms. They have very wide wings for flying. These are sometimes called "barn door wings." Their wings help them fly in a slow, buoyant way. In Korea, wild birds averaged 10.3 kilograms. They can even fly near Mount Everest. One bird was seen at a very high altitude. This is possible because of a special part of its blood. This part helps them take in oxygen in thin air.

Most of these birds live in mountains and hills.

They like dry areas like meadows and grasslands. They are often alone or live in pairs. They build very large nests in tall trees. These nests can be 2 meters wide. They use sticks and twigs to build them. Most pairs lay only one egg. The egg is white with red or brown spots. It takes about 50 to 62 days to hatch. The parents work together to raise the young.

The cinereous vulture (Aegypius monachus) is a massive raptor within the Accipitridae family.

It is often called the black vulture, Eurasian black vulture, or monk vulture. This bird plays a vital role in its ecosystems by consuming carcasses. By eating carrion, these vultures help reduce the spread of diseases. They are among the largest birds of prey in the world.

This species is a key part of the natural cleaning process in many environments.

To survive, these vultures have developed incredible biological defenses. Eating dead animals exposes them to many different pathogens, which are germs that cause disease. A 2015 study sequenced the bird's entire genome to understand how it stays healthy. Scientists compared the vulture to bald eagles to find specific genetic variations. They discovered that the vulture has special immune defense responses. It also has high levels of gastric acid secretion. This strong acid helps the bird safely digest carcasses. These genetic traits also support efficient respiration, or breathing, in difficult environments.

Physically, the cinereous vulture is a giant of the sky.

It is the largest member of the Accipitridae family in the Old World. While males can weigh around 10 kilograms, females can reach weights of 12 kilograms. In a Korean study of wild birds, the average weight was 10.3 kilograms. Their wings are very broad and are sometimes called "barn door wings." These wings allow for a slow and buoyant flight style. The birds can even fly at extreme altitudes. One vulture was observed near Mount Everest. This is possible because of a specialized hemoglobin alpha subunit. This part of their blood has a high oxygen affinity, meaning it picks up oxygen efficiently in thin air.

There are many names for this bird based on its appearance and history. The genus name Aegypius comes from a Greek word for vulture. An ancient writer, Aelian, described the bird as being halfway between a vulture and an eagle. The name "monk vulture" refers to the bird's bald head and the ruff of feathers around its neck. This ruff looks like a monk's cowl. The name "cinereous" comes from a Latin word meaning ash-colored. This was used to distinguish it from the much smaller American black vulture. While they share a name, the American species belongs to a different family called Cathartidae.

Taxonomically, the cinereous vulture is most closely related to the lappet-faced vulture.

This pair is then related to the white-headed and red-headed vultures. The cinereous vulture is a dark, blackish-brown bird. Adults have a pale head covered in fine blackish down. The skin on the head and neck is bluish-grey. Their massive bill is one of the largest in its family. The exposed culmen, or the top part of the bill, measures 10 centimeters. This large bill is supported by a relatively small skull. Immature birds look different, with sepia-brown feathers and grey down on their heads.

These birds live across much of temperate Eurasia.

Their range stretches from Spain and Portugal in the west to Mongolia and Korea in the east. They are found in the Middle East, Afghanistan, and northern India. They prefer hilly or mountainous areas with dry, semi-open habitats. This includes meadows, steppes, and grasslands. In China and Tibet, they often live in mountainous forests or alpine meadows. They require undisturbed and remote areas to thrive. They are generally permanent residents, though some may migrate during hard winters.

Cinereous vultures are mostly solitary or live in pairs.

They build huge nests using sticks and twigs. These nests can be 2 meters wide and 1 meter deep. They are often built high in trees like oaks or pines, or sometimes on cliff ledges. A single nest can be used for many years and may be decorated with animal skins. Most pairs lay only one egg at a time. The eggs are white or pale buff with red or brown spots. The incubation period lasts between 50 and 62 days. Both parents work together to raise the young through cooperative efforts.
