| Behaviors: |
Cheetahs
are the most diurnal of all the cats. Females are typically solitary
whereas males may be either solitary or form coalitions. Cheetahs
are afraid of lions and will surrender their prey to hyenas. Even
vultures can intimidate this cat. Most of the hunting takes place
during the day, but during the heat of the day they rest. Male coalitions
and females with sub-adult cubs will use their combined might to bring
down game the size of yearling and two-year-old wildebeests.
Because the Cheetah’s prey tends to be migratory, their territories
cover a wide area. When young reach 17 to 23 months of age, they
separate from their mother. Female offspring will stay within their
mother’s home range, but alone. Males will emigrate and typically
wander great distances. Transient males run the risk of injury and
death if caught trespassing on established male territories. Males
compete for the best hunting grounds and defend areas much smaller
than female ranges (reverse from other carnivores).
Male coalitions – littermates often stay together for several
months after separating from their mother. Females leave this sibling
group by their first estrous (about 2 years).
Cheetahs seldom lie in contact with one another. Greeting ceremonies
rarely go beyond cheek rubbing.
Hunting – Cheetahs walk alertly using termite mounds and
trees with low branches as vantage points to spot potential prey.
If a group of gazelles is moving in their direction, Cheetahs may
just use these elevated positions to wait for the prey to come to
them. Cheetahs may approach slowly and openly. An alert herd may
just stand and watch this approach or trot out to investigate. Before
the herd takes flight (within 197 to 230 feet), Cheetahs will gallop
at them accelerating only after they have selected a particular
quarry. If a herd is grazing unsuspectingly, Cheetahs may rush from
over 300 feet away and try to get close enough to select a quarry
before it has detected the cheetah’s advance. Whenever cover
is available, cheetahs will stalk as close as possible, walking
semi-crouched with head lowered to shoulder level, trotting, freezing
in mid-stride when game looks up, dropping to the ground, lying
crouched or sitting. Once within range, flight triggers pursuit.
An antelope or warthog that stands their ground may not be chased.
The average speed during the chase is about 40 mph. If a cheetah
fails to over take their quarry within 960 feet, its breathing rate
goes up to 150 respirations/minute and body temperature soars. The
cheetah must cool down for ½ an hour before it can try again.
If the cheetah overtakes the prey, it still may not catch it. The
harder the prey runs, the easier for the cheetah to upset its balance
by striking the rump, thigh or hindleg. After subduing quarry, a
cheetah drags it to cover and then settles in to eat while keeping
a wary eye out for predators and scavengers. A cheetah may consume
approximately 30 lbs. of meat at one sitting and may not feed again
for 2 to 5 days. Females with cubs are obviously kept busier. Most
of the bones, skin and digestive tract are not consumed. Cheetahs
will not return to a kill.
Vocalizations are many and varied amongst cheetahs. The birdlike
chirp may be heard up to a little over a mile away. A mother calling
to her hidden or lost cubs uses it. It is used between greeting
or courting adults. Or, cubs may use it around a kill. The intensity
of the chirp tells the listener about the degree of excitement of
the caller. Another vocalization is the churring, a staccato, high-pitched
growling that is less far reaching. Cheetahs also growl, hiss, snarl
and coughing anger or fright, but less frequently than the big cats.
Bleating, the equivalent to meowing, is a sound of distress. Small
cubs disturbed in hiding sometimes make a sound similar to the breaking
of sticks.
Scent-marking with urine, feces, scuffing and clawing on landmarks
are used by females and males. Females may scent mark more when
coming into estrous.
Minimum age for a first birth is approximately 21 to 22 months
of age. Gestation period is between 90 and 95 days. Litters are
on average 3 to 4 offspring with 18 months between birth and the
next conception. Cheetahs are perennial breeders with no set breeding
season.
Cheetah mothers withdraw to cover to give birth and hide cubs.
Newborns are blind at birth and weigh between 5.25 and 10.5 ounces.
Young have been observed in the following types of “play”:
stalking, pouncing, chasing, boxing, wrestling and tug-o-war. They
run with tail raised, climb trees and play “king-of-the-mound”.
The most common form of play that begins at age 3 months is chasing
and swatting at each other’s hindquarters, a typical way of
bringing down prey.

| Special
Interest: |
Of
the Serengeti cheetahs, less than ½ of the cubs survive their
first 3 months. Lions, leopards, hyenas, wild dogs, jackals and eagles
will prey on young. Even adult cheetahs may be killed by the larger
of these carnivores.
The King Cheetah (Acinonyx jubatus rex) first described in 1927
has longer, softer fur and a partial replacement of normal spots
with dark bars. Only 13 skins have been recorded and they all came
from Zimbabwe and adjacent areas. Initially classified as a subspecies,
today it is generally accepted as merely a variety of the African
Cheetah (Acinonyx jubatus).
The cheetah is the only living representative of this genus. There
are seven recognized subspecies.
