Researchers believe that all but a few of the world's
cheetah died in an ice age 10,000 years ago. The population bred up and
there were about 100,000 cheetahs, possibly all descended from a single female,
in 1900. Today, there are around 12,000 with 10% in captivity. Due to the
expansion of humans and illegal hunting, the range of the cheetah is now limited
to portions of sub-Saharan Africa.
The greater Serengeti ecosystem contains between 1000 and 2000
cheetahs, the second largest surviving population. While cheetahs are active
during the day and are not rare in the Serengeti, they can be hard to spot lying
low in the grass. We were lucky to get so close to these cheetah cuties.
This streamlined cat is built for speed: special paw pads and
semi-retractable claws provide exceptional traction, large nostrils and lungs
provide quick air intake and the long heavy tail acts as a rudder for stability.
But this intense speed is taxing, they can only maintain their top speed of 115
km/h for about 300 metres.
A cheetah's hunt begins as a long stalk followed by a short burst
of their fabled speed. They bring quarry down by tripping it. Then, like other
cats, cheetahs go for the throat: they clamp down with their jaws. The exhausted
prey quickly dies from lack of oxygen.
Cheetahs have been kept captive for thousands of years as they
have a tendency to tameness. They were a preferred pet of royalty since the days
of the pharaohs.
These two (probably brothers in "coalition"), like most of the big cats we got close to, acted like they had eaten recently. Nonetheless, Spice was nervous while posing for this picture; she knows that big male cats will kill the young of other cats. King of the beasts is misleading since female lions do most of the hunting while the males laze around. Male lion's bulk and conspicuous manes reduce their stealth and hunting ability. Once the females, often employing strategic ambushes, bring down prey, the males shove the lionesses and cubs aside and eat their fill. On second thought, this is rather kingly behaviour.
While cats have prospered all over the world through millions of
years of change, all big cat species are now threatened. Lions have been
eradicated from most of their former range, including Europe, the Middle East
and almost all of India. The lions of sub-Saharan Africa, concentrated in parks
and reserves, are not considered endangered. Lions are the most socialable and
co-operative of all cats which may help them survive. The Serengeti is home to
about 3,000 lions, the largest concentration of big cats in the world.
Lions are primarily nocturnal but easy to find lying around
during the day. Lions spend up to 20 hours a day sleeping and "conserving
energy". Communal hunts usually take place early and late at night; but lions
can become active any time, day or night, hungry or gorged, when easy
opportunities to catch prey arise.
The Serengeti lion population has been relatively stable except
for a canine distemper virus epidemic in 1994 which killed one in three lions.
The virus entered the Serengeti via the many domestic dogs kept in villages
surrounding the park. Disease transmission from domestic dogs also infected the
wild dogs of the Serengeti, which were wiped out in the early 1990s.
The ever vigilant Athumani, who showed us a scar on his arm where
he had been gouged by a lion cub years ago, scans the horizon while posing for
this picture. Accredited guides in Tanzania are highly trained professionals who
attend refresher courses every year. It really does not look good for them when
a client gets eaten. Animal attacks are not common, however. Car crashes pose a greater danger. Of the three great cats of Africa, leopards (sometimes called panthers) are the most elusive. The leopard has been called the quintessential cat: "secretive and silky smooth, a solitary (the only exceptions are mating and mothering) animal of the darkness."
The best
way to find a leopard is to look for the distinctive tail hanging over a branch.
Camouflage spots mimic the dappling of shadow and light of the shaded areas
preferred by leopards. Smaller than lions, leopards are bigger, stronger and
slower than cheetahs. Leopards use this strength to drag prey high into trees
for safekeeping. With a range that still stretches from the Atlantic coast of
Africa to the Pacific Coast of Asia, leopards are the most widely distributed
great cat. While classified as endangered, they have proven more adaptable in
the face of human expansion than cheetahs, lions or tigers.
