Wildbeest Migration pag93 Each year the sarin Getty planes and Tanzania are home to one of the greatest animal migrations on earth. Some 2000000 animals begin a round trip that will take them almost 2000 miles. Fossil evidence suggests that modern wildebeest raised these planes more than 1000000 years ago. At the beginning of each year the wildebeest gather on the outer edge of the Serengeti all giving birth in the same month. Rapidly their numbers swell. The cavs can run as fast as their mothers within 2 days of being born. No one knows what triggers the migration there is no clear signal it just takes one or 2 sniffed the air and decide the time is right to leave. The migrating animals journey is a long and difficult one even without the attention of predators around 200000 of the weakest wildebeest and zebras will die from starvation disease or exhaustion during the migration. Every day fresh carcasses are left behind. The migrating animals rest at the streams and regroup. A single cat finds it tricky to bring down a full drum wildebeest not if it can separate a wildebeest half off from its mother then it has a chance of a meal. Wohl in Kenya's Maasai Mara the migrating herds arrive. Rains have created a huge area of water grazing. Here will be used will stay until the smell of November's short rains tell them it's time to regroup and head southwards back towards the Serengeti.
