The Maasai Mara houses a variety of wildlife, including one of its most iconic inhabitants - the wildebeest. Wildebeests are also referred to as gnus and are native to certain parts of Africa. There are two distinct species, which are differentiated by their physical appearance: black wildebeests and blue wildebeests. These social animals often form large herds that can number in the thousands.
