Endangered speciesAn endangered species is a population of organisms
which is at risk of becoming extinct because it is either few
innumbers, or threatened by changing environmental or
predation parameters. The International Union for
Conservation of Nature (IUCN) has calculated the
percentage of endangered species as 40 percent of all
organisms based on the sample of species that have beenevaluated through 2006. Many nations have laws offering
protection to conservation reliant species: for example,
forbidding hunting, restricting land development or creating
preserves.Only a few of the many species at risk of extinction actually
make it to the lists and obtain legal protection like Pandas.
Many more species become extinct, or potentially will
become extinct, without gaining public notice.

Himalayan Wolf
The terms Himalayan wolfand Canis himalayensis have been
suggested by several Indian biologists for recognition as a critically
endangered canid species, distinct from Canis lupus. In its
morphological features, social and reproductive behavior, the
Himalayan wolf resembles the Tibetan wolf, Canis lupus chanco.
However, the IUCN Wolf Specialist Group has not taken a position
regarding this issue. The editors ofMammal Species of the
World consider the small population to be Tibetan wolves a subspecies
of the gray wolf.
Distribution
Kalpa, Himachal Pradesh
The Himalayan wolf may represent an ancient isolated line of wolves
consisting of a small population of about 350 animals. They inhabit an
area of 70,000 km 2 in the trans-Himalayan region ofHimachal
Pradesh, Jammu and Kashmirinnorthern India, and are adapted to
the cold environment.

Indian VultureThe Indian Vulture (Gyps indicus) is an Old World vulture and is
closely related to the Griffon Vulture, G. fulvus. It breeds mainly on
crags in the hills of Sind in Pakistan, central and peninsularIndia.The birds in the northern part of its range once considered
a subspecies are now considered a separate species, the Slender-
billed Vulture Gyps tenuirostris. These were lumped together under
the name Long-billed Vulture.
The species breeds mainly on cliffs, but is known to use trees to nestin Rajasthan. Like othervultures it is a scavenger, feeding mostly
from carcasses of dead animals which it finds by soaring over
savannah and around human habitation. They often move in flocks.
The Long-billed Vulture is a typical vulture, with a bald head, very
broad wings and short tail feathers. It is smaller and less heavily-builtthan the EurasianGriffon, usually weighing between5.5 and 6.3 kg
(1213.9 lbs) and measuring 80100 cm (3240 in) long and 205 to
229 cm (8191 in) across the wings. It is distinguished from that
species by its less buff body and wing coverts. It also lacks the
whitish median covert bar shown by Griffon.

Namdapha flying squirrelThe Namdapha Flying Squirrel (Biswamoyopterus biswasi), the sole
species placed in the genus Biswamoyopterus, is
an arboreal, nocturnal flying squirrel endemic to India, and is listed as acritically endangered species due to habitat loss. First collected
in Deban (on 27 April 1981), no population estimates are available forB.
biswasi, but the known habitat is tall Mesua ferrea jungles, often on hill
slopes in the catchments area ofNoa Dihing river(particularly on the
western slope ofPatkoi range) in North eastern India .The NamdaphaFlying Squirrel, also known as the Biswamoyopterus Biswasi, is
becoming extinct because it is losing its habitat and is prey for other
animals. The Namdapha Flying Squirrel is similar to other flying
squirrels except of the color and other features. Like other flying
squirrels, the most distinctive feature of this species is the muscularmembrane that extends along the sides of the body, from the front legs
to the back legs. This membrane is like a parachute because when the
animal jumps form a tree to another tree, it is able to steer by moving its
legs and tail and controlling the membrane. The Namdapha Flying
Squirrel is found mostly in India and Asia.
