The Serengeti National Park, the largest in Tanzania,
is about 5,700 sq miles in area. The park's name, Serengeti, means
'endless plains' and is derived from the Maasai language. 
The park lies in a high plateau between the Ngorongoro highlands
and the Kenya/Tanzania border, and extends almost to Lake Victoria.
The park encompasses the main part of the Serengeti ecosystem. The
ecosystem is defined by the dominant migration route of the wildebeest
and extends into the game reserves and conservation areas that surround
the Park's boundaries, supporting over 4 million mammals and birds
in what is probably the greatest concentration of wildlife in the
world.
It is probably the short grass plains of the Seronera area in the
South of the Park that are well known to the visitor. Here we find
kopjes, the rocky outcroppings from the sea of grass surrounding
them. These form habitats for several species and viewpoints for
larger predators, especially the big cats.
Equally scenic and with its own distinct ecosystem is the acacia
Savannah and wooded grasslands in the North of the Park in the Lobo/Grumeti
area where the Serengeti meets the Kenyan Maasai Mara. It is in
this region that the Great Migration begins to congregate for the
push to the birthing plains of the South.
The Great Migration is a sight that has to be experienced first
hand to be believed. Anyone who sees the huge numbers of wildebeest
gathering before trekking north will witness a marvelous sight.
Throughout the world it is rare for animal migrations to be completed
undisturbed and it is an important conservation achievement that
the Tanzanian government has protected this wilderness area and
allowed the wildebeest to migrate freely.
One of the most unique and remarkable wildlife experiences in the
world is the annual migration of plains game such as the wildebeest,
zebra and gazelle from the central plains of Serengeti,
westwards or northwards towards the Maasai Mara in search of water
and pasture, and back again; this pattern is to be repeated year
after year like there is an in-built clock prompting the amazing
phenomenon. As the herds move to new grazing ground, they are followed
by predators such as lions, hyenas, jackal and hunting dogs waiting
for weak prey while vultures soar overhead waiting for their share
of the kill. By some estimates, the migration can involve over a
million assorted wildlife representing about a quarter of the population
found in the Serengeti."
The annual migration into Kenya (in a continuous search of water
and pasture) of more than 1.5 million wildebeest, zebra and gazelle
is triggered by the rains and usually starts in May, at the end
of the wet season. Called the Great Migration, this constitutes
the most breathtaking event in the animal kingdom ever known to
humans. As the dry season intensifies, the herds drift out towards
the west, crossing the Grumeti River, and to the north (to Lake
Victoria, where there is permanent water), heading for the permanent
waters of the northern rivers and the Mara. The migration instinct
is so strong that animals die in the rivers as they dive from the
banks into the raging waters only to be dispatched by crocodiles.
The survivors concentrate in Kenya's Masai Mara National Reserve
until the grazing there is exhausted, when they turn south along
the eastern and final stage of the migration route.
Before the main exodus, the herds are a spectacular sight, massed
in huge numbers with the weak and crippled at the tail end of the
procession, followed by the patient vigilant predators, including
lions (the adult males of Serengeti have characteristic black manes),
cheetahs, hunting dogs and spotted hyena. The migration coincides
with the breeding season, which also causes dominance fights among
the male of the herd.
