Today on Animal Fact Files we’re discussing pandas.
Also known as the giant panda, these bears are perhaps the best known animals for conservation.
For a long time pandas were listed as endangered to extinction;
currently, they’ve been moved from endangered to vulnerable, meaning conservation efforts have
helped secure the future for this species, though they’re not out of the woods, yet!
There are estimated to be fewer than 2,000 pandas living in the wild as of this recording.
Pandas are endemic to central china and currently exist in fragmented populations
and habitats. Pandas spend most of their time on the ground but they’re also able to climb trees
and can swim! Their habitats include mountainous forests where bamboo is present. For a long time
their classification was disputed . They look like bears but have a strange thumb-like structure
to help them hold bamboo.This structure is not present in other bears and bamboo is a curious
food source for carnivores. Originally believed to be more closely related to red pandas because
they had a similar diet, giant pandas were named after red pandas! Pandas are some of the only
carnivores that have adapted to an almost entirely vegetarian diet. That being said, they still have
the digestive system of carnivores, so they can’t get much nutrition from the bamboo they consume.
Less than 20% of what they eat provides the bears nutrition, meaning in order to meet their dietary
requirements, pandas have to eat a lot! Pandas spend upwards of 14 hours a day eating during
twilight hours and spend the rest of their time sleeping. In fact, they’re so big on
conserving energy, they rarely travel! Plus, with all that food going in, they have a lot
coming out. These bears can poop upwards of 100 times a day, and even do number two while napping!
Pandas can also eat other plants, fruits, insects, and may occasionally take small mammals, however,
it’s been observed that the gene that recognizes the umami flavor in meat has been repressed in
pandas meaning they can’t really taste meat - so it’s no wonder they don’t really eat it!
In contrast to most other bears, pandas don’t undergo a state of low activity during the year,
sometimes called hibernation, though like we discussed in our bear episode that term being
used for bears is debated. Pandas are also on the smaller side of the bear scale averaging about 225
pounds (102kg) in weight. For comparison, these bears are about the same size as the American
black bear. What’s amazing is that panda babies only weigh about 100 grams when they’re born!
Pandas are relatively solitary, but do come together for the mating season from march
to may. Females become more vocal and scent mark to let males in the area know they’re
ready to mate. Mating is a quick process and the male leaves shortly after. Gestation in pandas
takes anywhere from 84 to 184 days because they may delay implantation of their eggs in order
to give birth at a more opulent time for food resources. Pandas typically have twins, but
in the wild the mother stops caring for one baby which then perishes. The surviving baby may remain
with its mother for 18 months before setting off on its own. Adult pandas are safe from harm
apart from anthropogenic threats including habitat loss and poaching, though conservation efforts
have helped reduce poaching kills. Baby pandas may be predated by martens, weasels, and wild cats.
There’s thought that pandas may be black and white to help break up their outline in a forest thus
giving them greater protection against predators. In the wild, pandas live about 20 years.
