Vultures / Gieren


Old world vultures

These vultures hunt by their keen eyes. Characterised by their bald head and neck, these vultures are commonly seen as "ugly" but are actually very diverse and spectacular.

One of the Better known vultures, It lives in europe and Asia although the European species are endangered

Lammergeier or Bearded vulture (Lammergier)
Neophron percnopterus

Far from your typical run of the mill vulture, these have no bald head. Even though he eats carrion like others, his diet exists 90% out of bone marrow. Lammergeiers can Swallow whole bones that can even match the size of a lamb's femur. They have mastered a way to break bones to pick it up and drop it midflight on rocks, the precision required can take up to 7 years to master by the birds.


Juvenile lammergeiers are black.

Palm-nut Vulture (Gierarend)
Gypohierax angolensis

This white bird is the smallest old world vulture, having a wingspan of 150cm (59in) and a height of 60cm (24in) . Perhaps of all the birds of prey he has the most remarkable diet, mainly feeding on fruit from the oil-palm. It also feeds on smaller living prey like crabs, moluscs and fish. The bird is not shy and therefore can be sometimes found near houses feeding on domestic poultry.





White-Rumped vulture (Bengaalse gier)
Gyps bengalensis

Closely related to the previous griffon vulture it shares the same typical looks that a lot of the Gyps species have, notably the slender bald neck and head but much smaller than his cousin. Although it is the smallest of the Gyps vultures it's still a pretty large bird still able to get measured up to 93cm(37in).





Hooded Vulture (Kapgier)
Necrosyrtes monachus

One of the more bizarre looking vultures, these have no fear at all of humans and can be found regularly breeding near human habitats getting the nickname "garbage collectors". When disturbed in their nests they cry something resembling "MAMA MAMA". They are abundant and fly in flocks able to be spotted in the day almost all the time.




Egyptian vulture (Aasgier)
