Wildebeest Emerging from River Mara, Maasai Mara National Reserve, Kenya

Blue wildebeest (Connochaetes taurinus) emerge from the Mara River after crossing it to reach the grasslands of the Maasai Mara National Reserve in Kenya as the rainy season begins in September. Wildebeest, also known as gnu and wild cattle, can travel long distances to reach productive grasslands. This population alternates between the southern Serengeti in Tanzania and the Maasai Mara in Kenya.
