Bearded Vulture

The bearded vulture is a large bird of prey found in mountainous regions of Europe, Africa, and Asia. It has a distinctive appearance, with a brown body and a white head with a black, beard-like ruff of feathers around its neck. Bearded vultures feed primarily on bones, which they drop from great heights to crack open and access the marrow inside.

What They Do

The bearded vulture, also known as the lammergeier, is known for its unique feeding habits and social behavior.

Behavior:

• Solitary: Bearded vultures are solitary birds and are typically seen alone, except during breeding season.
• Territorial: They defend their territories fiercely and will attack intruders.
• Soaring: They spend much of their time soaring in the sky, using thermals to gain altitude with minimal effort.
• Playful: They have been observed playing with objects, such as sticks, by dropping them and then catching them in mid-air.

Feeding:

• Bones: The bearded vulture is one of the few bird species that feed primarily on bones, which they obtain from the remains of dead animals.
• Dropping: They drop large bones from great heights to crack them open and access the marrow inside.
• Cooperative Feeding: Bearded vultures have been observed cooperating with each other when feeding on large animal carcasses.

Breeding:

• Nesting: Bearded vultures build large nests on cliff faces or in trees.
• Mating: They mate for life and pairs will often perform aerial displays together.
• Egg Laying: The female lays one or two eggs, which are incubated by both parents for about 50-55 days.

Overall, the bearded vulture is a unique and interesting bird, with a distinctive appearance and behaviors that set it apart from other birds of prey.

What They Eat

The bearded vulture is a scavenger that primarily feeds on the bones of dead animals. It is known for its unique feeding habit of dropping large bones from a height onto rocks to crack them open and access the nutritious bone marrow inside. The bird can swallow small bones whole, but larger bones are too tough to be broken by its beak, hence the need for this process. In addition to bones, the bearded vulture may also feed on other parts of dead animals, such as skin, tendons, and cartilage. While it primarily feeds on carrion, it has been known to hunt small live animals in times of food scarcity. The species is also able to locate and feed on the bones of animals that have been buried underground, making it one of the few species capable of locating food in such an unconventional manner.

A bearded vulture has several adaptations that allow it to eat bones, which are a major part of its diet. Its powerful beak, made of keratin, is capable of cracking open bones and crushing them to access the nutritious bone marrow inside. Its gizzard, or muscular part of the stomach, is also specially adapted to handle the hard, sharp pieces of bones, with a lining that is thicker and tougher than that of most other birds.

Nest, Eggs, and Young

Bearded vultures nest on cliffs and other high, inaccessible ledges. They build large nests made of sticks, which they add to year after year. A pair of vultures will lay one or two eggs, which are incubated for about 55 to 60 days. Both parents help to incubate the eggs and care for the young. Unfortunately, bearded vultures exhibit an evolutionary behaviour called ‘canism’. If two chicks hatch, the older chick will kill the younger to help ensure its own survival. In captivity, we remove the second egg, hatch it artificially and raise it with foster parents to prevent this.

When the chicks hatch, they are covered in down and have a distinctive black faces. They are fed by their parents for several months, gradually learning to hunt and feed themselves. Young bearded vultures will stay with their parents for up to two years before they reach maturity and start to breed themselves.

Bearded vultures are long-lived birds, with some individuals known to live for over 30 years in the wild. They are considered to be Near Threatened by the International Union for Conservation of Nature (IUCN) due to their decreasing populations and they face some threats, such as habitat loss and disturbance, and poisoning from pesticides and other chemicals.

Why They Need our Help

Bearded vultures are facing multiple threats to their survival, including habitat loss, hunting, and the use of poison in their food sources. In many regions, they are also persecuted by livestock farmers who see them as a threat to their animals. The use of poison to kill predators and vermin has had a devastating impact on many bird of prey populations, including the bearded vulture, which are known to feed on the poisoned carrion. In addition, the decline of traditional herding practices and the associated loss of food sources have also had a negative impact on their populations. Conservation efforts are needed to protect the habitats of these birds and to reduce the threat of poisoning, hunting, and persecution. Restoration of traditional herding practices and the creation of protected areas can also help to ensure the survival of the species.
