This wonder of nature that takes place every year in the Serengeti-Mara ecosystem is unique in the world. During this great period of migrational animals will travel more than 2000 miles and shall devour more than 4000 tons of grass per day. A quarter of a million animals will be released for the first time, many others will die. Every year 5% of the population of wildebeest will die, many because of hunger, diseases, predators,… but the circle will be completed again.
This migrational movement of these huge hordes of animals is circular and begins in the month of January in the southeast of the Park in the Ndutu region close to the entrance door of Naabi Hill, one of the main access to the Park gates. The migrational phenomenon is closely linked to rains, so each cycle is different. Not every year the large herds are concentrated in a certain place at a certain date, but it will be the life cycle of rains who determine the final movement. Until the month of may, large herds often remain in the southeast of the Park (Ndutu, Naabi, Moru) and even in the surroundings of the Ngorongoro Conservation Area. More than 1 million wildebeests, 350 thousand of Thomson´s gazelles and Grant´s gazelles as well as some 50 thousand zebras will meet to deal with the great cycle of life. During the months of June and July the migrational core thickness has moved through Maswa reserve, as well as the areas of Nyamuma, Handajega up to the banks of the dangerous Grumeti River where crocodiles will be waiting for its big annual banquet. In August and September, the vast majority will reach the North of the Park through the reservation of Grumeti and Ikarongo. It is from then on, when the great Kenyan Masai Mara is awash with animal life until at the end of November the large herds again take southbound to return to where it all began.
The Great Migration month by month.
The great migration is located in long plains in the southeast of the Serengeti in the surroundings of the Ndutu Lake. This month as in December are the months where are produced greater number of births of zebras in the plains of the Serengeti.
Migracional core thickness remains concentrated in the southeast of the Serengeti Maswa reserve and in the surroundings of the Ngorongoro Conservation Area. It is a month which produce a large number of births of wildebeets.
It is the beginning of the heavy rainfall. Large herds are concentrated in the areas of the southeast of the Serengeti.
It’s a very rainy month in Serengeti where even large herds are concentrated. The wildebeest begin to disperse towards the Northwest of the Park through the Grumeti and Mbatageti rivers.
Large herds are scattered in the area of the Grumeti River Northwest of the Serengeti.
The rains play to an end. The herds remain in mediation of the Grumeti River and begin to disperse towards Ikorongo controlled area in the North crossing the dangerous Grumeti River where many animals will perish at the hands of the crocodiles. Under normal conditions some flocks should hold for these dates to Seronera areas.
The great migration has gone through the Grumeti and tends to spread along Ikorongo and Lobo area.
On this date the first flocks arrive at the tanzanian Mara River crossing Ikorongo controlled area. The threat of predators start being a reality. Under normal conditions on this date the first herds would begin to cross the dangerous Mara River with his big crocodiles and many other predators waiting for his opportunity.
Large herds make incursion into the Kenyan reserve of Masai Mara, leaving behind the Tanzanian border
The Mara Plains are full of herbivores. Under normal conditions this is without doubt the best month to visit Masai Mara since it is full of animals after sustained rainfall. At the same time this is the driest month in the neighbouring Serengeti. The abundance of green pastures and water in the Mara make this month a show that one should not be missed.
The hordes of wildebeest, zebras and gazelles start again return to the Serengeti in Tanzania again crossing the Mara and the Grumeti rivers to entering the northern part of the park again.
Again large herds have migrated completely to the Serengeti in the controlled area of Loliondo and mediations of the Ngorongoro Conservation Area as well as in the middle of the park. Thousands of animals have died at the hands of predators, hunger or diseases, but hundreds of thousands have seen the light for the first time to start this great migracional movement in the coming months.
