2011-10-30 Aves bird of the week - Egyptian Vulture - Neophron percnopterus
The Egyptian Vulture - Neophron percnopterus - is
widely distributed and may be found in southern Europe, Africa and Asia. Unfortunately it is now extinct in South Africa. It has sometimes also been known as the Pharaoh's
Chicken. It is a small vulture
with white and black flight feathers and a wedge tail. The bill is slender and
long and the tip of the upper mandible is hooked. The feathers on the neck are
long and the bill is black. The facial skin is yellow and crop is unfeathered.
Young birds are blackish or chocolate brown with black and white patches.
This species is
often seen soaring in thermals often with other vultures. They are usually
silent but near the nest they make high-pitched mewing or hissing notes.
Most of its
foraging time is spent scavenging, soaring high up in the air before descending
to the ground once it has found a carcass.
It sometimes uses stones to break the eggs of birds making it one of the few
birds that make use of tools. They feed on a range of food including mammal
faeces, [especially human], insects in dung, carrion as well as vegetable
matter and sometimes small live prey.
They roost
communally and nests are often traditionally used year after year. Birds are
however usually seen singly or in pairs. They are socially monogamous and pair
bonds may be maintained for more than one breeding season. Extra-pair
copulation with neighbouring birds is however noted and adult males tend to
stay close to the female before and during the egg laying period. The nest
sites include cliffs, buildings as well as trees.
The nesting
season is February to April in India.
Both parents incubate and the two eggs hatch after about 42 days. The second
chick may hatch after an interval of 3 to 5 days or more. The longer the
interval, the more likely is the death of the second chick due to starvation. The
chicks stay in the nest for approximately 77 days.
The Egyptian
Vulture is declining in large parts of its range, often severely. In Europe and
most of the Middle East it is half as plentiful as it was about twenty years
ago, and the populations in India
and Southern Africa greatly declined.
