Physical
Description
Giant
Pandas have a thick fur that is white over most of their bodies,
and is black on their arms, shoulders, legs, ears, and in patches
around their eyes. The reason for these unique markings are unknown,
but it's believed to both act as camouflage in snow and to make
Pandas more visible to one another. Pandas are solitary animals
with poor eye site, so seeing these distinct markings makes it
much easier for them to avoid each other in the wilderness.
Pandas
weigh about 200-250 pounds (85-125 kg), have a body length of
4-5 feet (120-150 cm), stand about 2-3 feet tall when on all fours,
and have tails that are about 5 inches long. Underneath
their tails, Pandas have scent glands that they use for marking
their territories. While Pandas have poor vision, they have an
acute sense of smell that makes it easy to track and recognize
each others scent markings.
While
Pandas have a lot in common with other bears, they have developed
certain characteristics that make it easier to eat their largely
vegetarian diet. Pandas have large jaw bones, as well as substantial
chewing muscles. Their molars are very wide and flat, making it
easier to crush and chew on bamboo. Also, their digestive system
has adapted to make bamboo digestion more feasible.
Breeding & Social Order
One
major obstacle of increasing the Panda population is their slow
and challenging reproduction rate. Pandas only breed once a year,
and only during a 2-3 day period in the Spring when females are
ovulating. While this small window of opportunity makes captive
breeding that much harder, Pandas do well with this method in
the wild. Using mating calls and scent marks, the normally solitary
Pandas are able to find a mate without much difficulty.
Pandas
reach mating maturity at about 5-6 years of age. If their partnering
is successful, Pandas undergo a 3-5 month gestation period, and
give birth to one or two babies. Unfortunately, when two cubs
are born, it is common for only one to survive.
When
baby Pandas are born, they are small (1/4 pound or 3-5 ounces),
almost furless, immobile for 3 months, and blind (their eyes remain
closed for up to 8 weeks). Though weaned fully in about 9 months,
cubs stay with their mother for up to two years. For this reason,
most Pandas only produce a cub every 2-3 years. Thus, many Pandas
produce about 5-7 cubs in their lifetime.
Though
they have lived up to 30 years in captivity, most Pandas live
to be about 15 years of age in the wild. Most of their time is
spent alone resting and eating, except for occasional moments
of social interaction with other Pandas that share their territory.
When they do socialize, Pandas are quite vocal, using various
noises to communicate different physical and psychological feelings.
Threats to Survival
The
future survival of the Giant Panda is uncertain. While efforts
to save them have helped their chances, Pandas still face many
threats, including habitat destruction, poaching, challenging
dietary needs, and reproduction problems.
Habitat
loss is the greatest problem facing Pandas. Though China is now
making efforts to preserve the few areas where Pandas still can
live, farming and deforestation still continue. Furthermore, past
habitat destruction has divided Pandas in to a few isolated communities.
This isolation can cause various problems, ranging from a smaller
gene pool for breeding to the possibility of starvation from a
lack of food or water sources.
Pandas
have not been prolific breeders in captivity. However, in the
wild, Pandas do not have this difficulty producing cubs. The problem
that exists is whether or not their slow offspring production,
coupled with a shrinking gene pool, can overcome the effects of
people and produce a healthy future population.
Though
not a huge problem, poaching of Pandas does still exist. Many
hunters are deterred by the penalties that are imposed on them
if they're caught, but the reward for successful hunters still
makes poaching appealing to a few. Accidental hunting is also
a problem for Pandas, as they are susceptible to being injured
by snares set for other animals.
Diet & Habitat
While
Pandas do still eat some small animals and other vegetation, their
diet consists almost entirely of bamboo. Unfortunately, their
digestive system is still better suited for a carnivorous diet,
and a majority of this bamboo is passed through their bodies with
little nutritious effects. Thus, Pandas spend about 14 hours a
day collecting and eating between 20-50 pounds of bamboo to meet
their dietary needs.
Not
only is a Panda's diet time consuming, but it's also a major factor
in its population decline. With people in China continuing to
convert many forested areas in to farm land, Pandas have an ever
decreasing roaming area. As people encroach further on its habitat,
the shy Panda must retreat in to areas where it's more and more
difficult to find both sufficient amounts of bamboo and a water
source.
Bamboo
does provide some hydration for Pandas, but not enough for survival.
So, Pandas will live within a mile (1 km) of a prime water source,
making it feasible to consume water on a daily basis. If a Panda
finds an area with ample bamboo, yet it's not close to a water
source, it will forego the food in search of an area that has
both food and water.
There
are over 200 types of bamboo, however, Pandas only eat about a
dozen of these varieties. When they had a larger living range
it was easier to find bamboo sources, but Pandas must now share
a limited amount of bamboo in the few mountainous areas that they
habitate.
Known
to have ancestors from up to 3 million years ago, Pandas used
to roam a a territory that included much of China and extended
to neighboring Myanmar (formerly Burma) and North Vietnam. They
are now confined to a few small Chinese mountain areas in Sichuan,
Shaanxi, and Gansu. These mountain ranges provide seclusion from
people, still have the types of bamboo that they eat, and provide
a good water sources from rain fall and melting snow.
Conservation Status (Endangered)
There are approximately 1,000 Pandas alive today in the wild,
and about 150 in captivity. While Pandas are now limited to several
Chinese mountain ranges that make up about 5000 sq. miles (13,000
sq. km), it is hopeful that some of these territories will be
preserved for them. Not only are the protection of these areas
crucial to the survival of Pandas, but they also are home to many
other rare plant and animal species, including the goat-like Takin.
General Information
Unlike
other bears, Pandas do not hibernate.
It's
not known if Pandas are able to see in color.
Though
rare, Pandas with brown and white coloring do exist.
Pandas
have enlarged wrist bones, which act as opposable thumbs and make
it easier for them to collect and eat bamboo.
Ailuropoda Melanoleuca, the scientific name for Pandas, means
'white and black cat-footed animal'. The Chinese name for Pandas
is Daxiongmao, which means 'large bear cat'.
