HIPPO ZOO FACTS
Since
the arrival of their first pygmy hippopotamus in 1927, the
National Zoo has had 58 births
to pygmy hippopotamuses. The National Zoo participates in the American
Zoo and Aquarium Association's Species Survival Plan for this animal.
Over the years, the National Zoo has sent pygmy hippopotamuses to zoos
in Portland, Fort Worth, Chicago, Philadelphia, Pittsburgh, San Antonio,
Canada, Venezuela, Argentina, Brazil, Chile, England, South Africa,
Sri Lanka, Singapore, and Thailand.
Zoos World Wide: There were 178 pygmy hippopotamuses in 74 collections
around the world, as of November 2003, . Most of these animals were
born in zoos to zoo-born parents.
Zoo Diet: The hippopotamus feds one flake of alfalfa twice a
day. This is a leguminous forage plant (like peas, beans, clover). These
plants are high in protein and a good source of vitamin E and selenium.
They are also eat two to three pounds (0.9 to 1.4 kg) of Low Protein
Herbivore Pellets per day. These food mixures are specially prepared
for large herbivores and include vitamin and mineral supplements. They
receive two pounds (0.9 kg) of kale per day and apples, grapes, and
bamboo as treats.
Social adaptation: They are not thought to be social animals.
Although pygmy hippopotamus look relatively small and docile, they can
be extremely aggressive when it comes to protecting their home or enclosure.
The hippos are familiar with their daily Zoo routine and do recognize
their keepers as food providers.
Winter: When temperatures are below 45 degrees F (7.2 degrees
C) or there is ice on the ground, the animals are usually kept indoors.
