Physical Characteristics
The most common large carnivore in Africa is the hyena . Over the years hyenas and
humans have come into close contact in Africa and, in earlier
times, in Asia and in Europe, often leading to mutual conflict.
In ancient times in Egypt hyenas were domesticated, fattened and eaten,
and in turn humans have on occasion become food for hyenas.
Reputed to be cowardly and timid, the hyena can be bold and
dangerous, attacking animals and humans.
Female spotted hyenas are dominant over the males and outweigh
them by about 3 pounds. It is difficult to distinguish between
the sexes in the field because external female genitalia have a
superficial similarity to those of the male. Why the female
hyena developed in this manner is unknown, but it may have been
necessary for them to appear large and strong to protect their
young from males, as hyenas have cannibalistic tendencies.
Habitation
Spotted hyenas are found in grasslands, woodlands, savannas,
sub deserts, forest edges and mountains.
Behavioral Traits
Spotted hyenas are organized into territorial clans of related
individuals. The center of clan activity is the den, where the
cubs are raised and individuals meet. Hyenas mark and patrol
their territories by depositing a strong-smelling substance
produced by the anal glands on stalks of grass along the
boundaries. "Latrines," places where members of a clan deposit
their droppings, also mark territories. Hyenas are social
animals that communicate with one another through specific
calls, postures and signals.
Hyenas usually bear litters of two to four cubs, which, unlike
the other two species, are born with their eyes open. Cubs begin
to eat meat from kills near the den at about 5 months, but they
are suckled for as long as 12 to 18 months, an unusually long
time for carnivores. This is probably a necessity, as most kills
are made far from the den, and hyenas, unlike jackals and
hunting dogs, do not bring back food and regurgitate it for
their young. At about 1 year, cubs begin to follow their mothers
on their hunting and scavenging forays. Until then, they are
left behind at the den with a babysitting adult.
Diet
The spotted hyena is a skillful hunter but also an opportunistic
scavenger. It consumes animals of various types and sizes,
carrion, bones, vegetable matter and other animals' droppings.
The powerful jaws and digestive tract of the hyena allow it to
process and obtain nutrients from skin and bones. The only parts
of prey not fully digested are hair, horns and hooves; these are
regurgitated in the form of pellets. The high mineral content of
the bones hyenas consume make their droppings a highly visible,
chalky white.
Predators and Threats
Hyenas have long conflicted with humans. African
legends and folklore associate the hyena with witchcraft and the
supernatural. Like many predators, hyenas become targeted when
they take livestock for prey.
Thought You Should Know
* Hyenas make a variety of vocalizations, including wailing
calls, howling screams and the well-known "laughter" used to
alert other clan members up to three miles away of a food
source.
* Hyenas eat a great variety of animal products, vegetation and,
according to campers, even aluminum pots and pans.
