Its immense geographical range extends from North Africa to South Africa and from Spain to China. Unlike most vultures, the bearded vulture has a head and neck fully covered in feathers. This difference is probably due to a difference in diet. Indeed, it mainly eats bones, and is therefore not soiled by the blood of carcasses. It can swallow whole bones 25 cm long and 3.5 cm in diameter. Bones with a diameter of 10 cm and weighing 4 kg are also a source of food for the bearded vulture. To consume them, it picks them up, flies, and drops them from more than 100 meters high onto a rocky site in order to break them into several pieces. These rocky sites are called ossuaries.
