Breeding and mating season
Blue wildebeest (Connochaetes taurinus
The cows (female Gnus) will calve (give birth to the young) in summer in the plains. After the females have given birth, the breeding season begins. The dominant males mark off (and defend) some territory. They do this with feces, and with scent.
Wildebeest are an important part of the ecosystem. With their dung, they fertilize the ground, and their trampling is good for new growth. They also provide food for predators, like lions and hyenas.
