Within the Ngorongoro Conservation Area
lies the renowned Ngorongoro Crater. Ngorongoro was a huge volcano that
collapsed inward millions of years ago, leaving a 18 km wide volcanic crater
(caldera). It is the largest intact unflooded caldera on earth. Our lodge was
amongst the clouds high on the crater rim at around 2300 metres elevation. As we
drove down the winding track through the lush rim forest to the crater floor 600
metres below, we joined this troop of olive savanna baboons.

Baboon troop coming
through
|
Baboon troops are complex societies that
travel about 6 km per day together in search of food. Baboons eat an enormous
variety of plants supplemented with shellfish, insects and even small mammals
like hares and infant antelope. A lodge manager told us that baboons keep
stealing his telephone satellite dish. He did not know what the baboons did with
all the equipment. Perhaps they are establishing BaboonTel.com.

Baboon
spotting
|
I think baboons, Africa's most widespread
primate and the largest of the monkeys, could serve as a ready excuse if I lived
in Tanzania: "Sorry I'm late, there was a lot of baboon traffic." Baboons have
even blocked
roads to protest
senseless killing.
|
Mmmm...
parasites
|
Grooming - removing parasites and dead
skin from another baboon - is an important social activity which relaxes and
unites members of the troop. Savanna baboons form long lasting male-female
friendships, a behaviour seldom observed in animals. Baboons join forces to
protect infants; few predators dare test a troop's defences. This cooperative
defence lets troops wander with impunity and use their opposable thumbs to thumb
their snouts at the lions.

Flocks and
herds
|
The crater floor is a self-contained world
apart, likened to Noah’s Ark in its preservation of animal diversity in a
relatively small area. Here roams the densest permanent concentration of
wildlife on earth (including 25,000 large mammals), enjoying year round water
and abundant food. Lake Magadi, alkaline due to its bed of soda (sodium
carbonate), occupies the lowest part of the crater floor.
|
Greater, lesser, they are all
flamingos
|
The lake supports thousands of
flamingos and other birds. Here are greater and lesser flamingo mingling,
along with some other birds. The greater flamingo is larger and has a pink bill
with a black tip. A filter feeder, it preys on invertebrates which it sifts from
the bottom mud using its bent bill.
Lesser flamingos, recognizable by their
darker bills, primarily eat spirulina, a blue-green algae found in the shallows
of alkaline lakes.

Flamin-go-ing

Flamingos live and travel in large groups. In this picture
they are flamingoing away.

One of the last black
rhinos
|
Ancient and massive, the Rhinoceros
is considered Africa's most endangered species. The high commercial value of
their horns has led to intense poaching. The black rhinoceros has declined from
a continental population of more than 100,000 in the 1960s to 2,500 today. Less
than 50 survive in Tanzania. This is one of seventeen black rhinos living in the
crater.
Seventeen, which includes two fertile females repatriated from South Africa
in 1997, may not sound like many but it is only due to intensive conservation
and anti-poaching efforts that any remain. The sheer crater walls act as a
natural barrier and help give them, one of the last viable free-ranging black
rhino populations, a fighting chance. Other Tanzanian rhinos live behind
protective electrified fences even more formidable than the Quebec City "Wall of Shame".

Bull
elephant
|
Peering down from the rim, we could
discern dots moving in the distance of the crater floor. Inside the crater, we
met up with these bull elephants. Elephant families stay in the highland
forests surrounding the crater and do not venture into the crater. Males leave
cow herds at 12 years or later, depending on when they reach puberty. Once on
their own, bulls alternately wander solo and associate with other bulls.
|
It must be
musth
|
Male elephants experience a highly sexual
state called musth, indicated by dribbling from a swollen, partially extended
penis. (Elephant penises curve forward and up when fully erect.) I don't know if
this is the case with this old bull and his "fifth leg." Maybe he's just
daydreaming or happy to see us.
Ngorongoro is not a National Park -- certain human settlements
and activity are permitted. When the British established the Serengeti National
Park in the fifties, they evicted the Maasai tribespeople
who had moved into the non-tsetse infected grasslands 150 years earlier. As
compensation, they were offered refuge in nearby Ngorongoro, already occupied by
fellow Maasai. No other Maasai were allowed to move in and no increase in their
livestock was permitted. Unlike many of Africa's conservation areas, the
Ngorongoro Authority manages a complex mix of wildlife, vegetation, water,
Maasai pastoralists and their stock, not to mention all them pesky tourists.
Although a small percentage of the population, the Maasai
(promoted as "photogenic" in tourism brochures) are the ethnic group best known
to visitors to Tanzania and Kenya. Most Maasai maintain a traditional tribal
lifestyle and live off their livestock: primarily milk but also meat and blood.
Some Maasai generate income from tourism including charging photographers,
offering tours and accommodation in their villages, and trading. I did not take
any pictures of Maasai, but don't worry, there's
plenty.
After the crater, we explored the Olduvai Gorge excavation site, known as the
"cradle of humanity". Many important fossils have been unearthed here, beginning
with a two million year old human skull found in 1959 by Mary Leakey. We didn't
find anything good, though.
