2. Giant Panda -
Ailuropoda melanoleuca
Order: Carnivora
Family: Ursidae
Geographic range: China - Very fragmented range
between 2000-3000m
Habitat: Does not build permanent dens, but seek shelter in trees in caves.
Also, unlike other bears, it does not hibernate, but descends to lower
elevations in the winter months.
Diet: Very strict energy budget! If they’re moving, they’re typically foraging.
Giant pandas can spend >12 hours feeding per day. Bamboo makes up
99% of the panda’s diet, although only 17% of the energy is extracted from
the plant’s leaves and stalks. (Their extra digit on hand aids in tearing the
bamboo while foraging.) To protect the digestive tract from it’s nutritional
source, their stomach walls are very muscular and gut is covered in mucus
to protect from splinters).Other foods besides bamboo giant pandas eat:
fruits of plants (like kiwi), small mammals, fish, & insects.

3. More background...
Closest relatives in AR: Grizzly Bear & Black Bear
Breeding season: March-May
Parental investment: Embryonic development lasts 1.5 months.
Altricial young (born blind, helpless, and covered in a thin layer of fur.)
Following baby panda birth, mothers will position babies into
suckling position. Mothers will play with their cubs, and Sometimes
mothers will wake up sleeping infants to play. A cub is typically weaned
from mother at 46 weeks and may stay with its mother for up to 18
months.
Typical lifespan in the wild: 10-15 years
Typical lifespan in captivity: 30-34 years
Known predators: humans. Enemies in the past may have included
animals like tigers.

4. Vocal communication
● When sexually receptive, females
will increase vocalization (bleating
sound)
● They will also increase scent
marking
● Can make up to 11 different
sounds
● Bark to intimidate
● Some other sounds:
○ Growling
○ Huffing

8. Tactile Communication
& Communication through
Coat-color
Mothers will wake infant giant pandas to
play with them.
Baby pandas will approach moms to
play as well.
Pandas are pretty solitary besides
mother-cub duos in the wild.

with aromatic
compounds
● These waxy
secretions of
scent will last 3
months
