Research

The research actions within the project aims to broaden our knowledge on the biology
and ecology of the Black and Griffon Vulture and help us understand better the major
threats for the species. They provide us with scientific evidences for more effective decision
making and planning of the conservation activities for these species.

Biology and ecology

big-butterfly

The Griffon vulture is sand-coloured to dark brown, with a white
head, neck and ruff. The primary- and tail feathers are dark
brown to black. Young birds have a brown ruff and are darker in
colour. The wings are long and wide and are resemble fingers.

The Griffon vulture feeds mainly on the softer parts of
carcasses, such as the muscles and viscera. Because of it’s
long neck, this species can reach far into the carcass without
snagging. Griffon vultures are very social in comparison to other
vulture species. They forage in groups and breed in colonies on
steep cliffs.
