What kind of eagle is the bearded vulture?

The bearded vulture is a large bird of prey belonging to the family Accipitridae and the genus Gypaetus.

They are named for the black, beard-like feathers below their beak. In English, they are called 'bearded vulture' or 'lammergeier.' The word 'lammergeier' comes from German and means 'lamb vulture.' This is because they were once mistakenly believed to prey on lambs. Unlike other eagles, they primarily feed on animal bones. They drop bones from great heights onto rocks to break them open and then eat the marrow inside. They also have extremely strong stomach acid that can dissolve bones.

Why do bearded vultures eat bones?

It is thought that bearded vultures evolved to eat bones as a way to avoid competition with other scavengers and efficiently obtain nutrients.

Bone marrow is highly nutritious and is a valuable food source for them. Bones are also rich in minerals, such as calcium, which are essential for their health. They have unique physical adaptations for eating bones. Their beaks are narrow and hooked, perfectly shaped for extracting marrow from bones. Their legs are short and powerful, ideal for gripping bones. Furthermore, they have extremely strong stomach acid that can dissolve bones. They are remarkably adapted to their bone-eating diet.

[Quiz!] From what height do bearded vultures drop bones?

Bearded vultures drop bones from heights of 164 to 328 feet (50 to 100 meters)!

They carefully select the drop zone, aiming for rocks to ensure the bones break. Once the bone is broken, they swoop down to eat the marrow. Sometimes they may even drop the bone repeatedly until it breaks. They are very persistent when it comes to accessing bone marrow.

[Quiz!] Why do bearded vultures have red feathers?

Adult bearded vultures have a white head and body with black wings. However, the feathers on their chest, belly, and legs are reddish-brown.

This is believed to be due to their habit of bathing in soil rich in iron oxide. The iron oxide stains their feathers reddish-brown. These red feathers are a symbol of beauty and a sign of health for them.

[Quiz!] Are bearded vultures endangered?

The bearded vulture is listed as 'Near Threatened' (NT) on the IUCN (International Union for Conservation of Nature) Red List.

This means that they are at high risk of becoming endangered in the near future. Their declining population is primarily attributed to these three factors:

・Habitat loss: Human development is encroaching on their mountainous habitat.

・Poaching: They are targeted by poachers for their feathers, talons, and beaks.

・Lead poisoning: They can be poisoned by ingesting lead bullets when scavenging on the carcasses of animals shot by hunters.

To protect bearded vultures, it is crucial to conserve their mountainous habitats, prevent poaching, and regulate the use of lead ammunition. We also need to raise awareness about the current situation of bearded vultures and encourage action to protect them.
