The number of flamingoes in Lake Bogoria varies each year depending on factors like availability of food and water levels. In one instance, heavy rainfall keeps them away because of the high water levels experienced in the lake. To get the best spectacle of the flamingoes on the lake, January and February, August to early October is the ideal time. This is the time they pitch camp at Lake Bogoria to feed as well as mate and nest the laid eggs. Most of them migrate from Lake Nakuru and other lakes in Tanzania.
