NATURE OF HUMAN NATURE
Red Panda
The Red Panda, or “firefox,” is
often referred to as the “lesser panda” in deference to the better-known giant
panda. Others prefer “first panda” – Western scientists described it 50 years
earlier, and gave pandas their name. Few people outside its native habitat have
even heard of the red panda, let alone seen one.
The red panda has been previously classified in the families
Procyonidae (raccoons) and Ursidae (bears), but recent research has placed it
in its own family Ailuridae, in superfamily Musteloidea along with Mustelidae
and Procyonidae. Two subspecies are recognized:
Ailurus fulgens fulgens: Found in Nepal,
northeastern India (West Bengal, Sikkim, Arunachal Pradesh), Bhutan, and part
of China.
Ailurus
fulgens styani (also known as a. f. refulgens): Only found in China (in the Hengduan Mountains in Sichuan and the
East Nujiang River of Yunnan Province) and northern Myanmar.
The head and body
length of red pandas averages 56 to 63 cm (22 to 25 in), and their tails about
37 to 47 cm (15 to 19 in).
Behavior
Red pandas are generally solitary, but there are a couple of exceptions to the rule. First, young red pandas grow relatively slowly, so they develop extended associations with their mothers that last for over a year. Second, red pandas have short relationships during the annual breeding season.
In terms of their ranging patterns, red
pandas behave much like larger carnivores. They tend to have overlapping home
ranges in which the individuals rarely interact with each other. This may seem
odd, since red pandas mostly eat bamboo. However, red pandas search for the
most tender bamboo shoots and leaves, and these prime specimens may be patchily
distributed — not unlike the prey of larger animals such as jungle cats. In
effect, the red panda’s habits reduce overcrowding and overuse of shared
resources.
The home ranges of female red pandas
often measure about one square mile, while males can live in areas twice that
size. Male home ranges frequently overlap with at least one female home range
and sometimes expand during the breeding season. Because red pandas constantly
need to conserve energy, they only cover 650 to 1,000 feet of their home ranges
per day and about 25% of their home ranges per month.
Red pandas have several ways of
marking their territories and home ranges. These include urine, secretions from
anal glands, and scents from glands on the pads of their feet. They have also
been known to use communal latrine sites to stake out territory and share
information with others. In addition, red pandas often communicate using body
language (such as head bobbing and tail arching) and a variety of noises (such
as a threatening “huff-quack” and a warning whistle).
Habitat and Range
Red pandas have a large range that extends
from western Nepal to northern Myanmar. The species also lives throughout
mountainous areas of southwestern China (Yunnan, Sichuan and Xizang provinces)
at elevations between 4,900 and 13,000 feet.
Red pandas only live in temperate
forests in the foothills of the Himalayas. The temperature in this region is
generally cool, and there is little annual variation. The southern slopes of
the mountains trap the water from seasonal monsoons, supporting forests of
firs, deciduous hardwoods, and rhododendrons. A bamboo understory grows in
these forests and provides the bulk of the red panda’s diet. However, these
swaths of bamboo are only found in narrow bands throughout the red panda’s
range. Thus, although red pandas are distributed across thousands of miles of
territory, they are restricted to these small, fragile areas because of their
dependence on the bamboo plants.
