Egyptian
Vulture can be located in Kerwa, Van Vihar and from Manav Sangrahalaya.
They are not that common but can be spotted if you spend some
time in these locations.
It is also
known as scavenger vulture or Pharaoh's chicken. Symbol of this
vulture is the first letter of egyptian alphabet. It is pronounced
as "ah." Drawings of this birds have been found on the walls of
Egyptian tombs.
Although common
enough, they were never found in the huge congregations that white
backed and long billed sometimes formed, and perhaps have escaped
the decline. These birds are not yet endangered, but they are
certainly less seen. They are distributed in a large geographical
area covering India, Africa and as a summer visitor to Southern
Europe returning to Africa in the winter.
The most important
thing about these vultures that I have seen in the discovery channel
is that its ability to breaks eggs by dropping rocks on them.
It finds an egg, picks up a rock in its beak, stretches to its
greatest height, and drops the rock. As per that program, the
rock seldom hits the egg and the bird doesn't seem to aim the
rock at all, but, it keeps doing this until it breaks the egg.
Then it feasts on the oozing interior of the egg. It is one of
the rare example of bird using a tool. It is the only bird known
to possess this ability.
The Discovery
channel episode also debated whether this behaviour is learned
or instinctive, with the help of some test they said that it attempts
to break any egg-shaped object irrespective of what it is made
of like fibre glass. infact captive Egyptian Vultures showed no
inclination to break Ostrich eggs. Egyptian vulture's habitat
includes rocky regions, often mountainous, hills, lowlands, plains,
wetlands, uplands, savannahs and semi- deserts and is occasionally
seen around human settlements. It flies with more wingbeats than
most vultures, but takes off much more gracefully, as it is built
lighter and smaller.

Once gliding,
the bird holds its wings flat, shifting them very little. It posesses
great endurance, and is able to fly up to 70 kilometers in search
of food. They feed on carrion, rotten fruits, eggs, rubbish, snails,
tortoises or lizards, human excrement, also very partial to lion's
dung. Occasionally catches live prey in the form of locusts in
flight. Also seen following farmers plowing the fields so that
it can catch disturbed insects. Often found hanging around slaughter
houses. Also favoures decaying fruits and vegetables salvaged
from human garbage dumps. Without
a sense of smell, egyptian vultures rely on their keen eyesight
to find all food. Their vision is twice as refined as that of
a human, allowing them to see an object 4 to 8 centimeters in
diameter from as high as 1000 meters. It grows to around 60-70
centimetres long and has white plumage with black wing tips. The
beak is thin with a blackish tip and the skin on the face and
neck is yellowish.
Egyptian
vultures are also famous for their beautiful flight displays.
This consists of dives and swoops. This is generally for choosing
partners. They fly high into the air and dive back down, grasping
claws on the way. they nest on rocky ledges and in cliffs, preferring
well-sheltered areas with many cavities, small caves, or occasionally
in trees and may be used several years running. These birds are
colonial nesters. If the nest of another species is vacant it
may occupy that instead. They lay 1 to 3 eggs, which they incubate
for 42 days. eggs are whitish or rusty-spotted. Interestingly,
they have the ability to lay a new egg if one is destroyed or
taken before hatching. Rearing of young, is done by both parents.
