10. Cinereous Vulture
Cinereous vulture, Aegypius monachus
Cinereous vultures (Aegypius monachus) are large birds of prey commonly found in parts of Eurasia. One of the heaviest flying birds on Earth, these vultures can weigh between 14 to 31 pounds.
Their bodies are covered with dark brown feathers, while the head and neck are considerably paler. Their heads are almost bald, making them appear rather ugly.
These vultures are usually found alone or in pairs, although they are observed in small groups while feeding.
Their diet consists mostly of dead animals – including the remains of both wild and domestic animals.
