Herds of blue wildebeest or brindled gnu (Connochaetes taurinus) spread across the floor of Tanzania’s Ngorongoro crater. Although they look like a frankinstein of animal parts, the wildebeest is a member of the antelope family.
During the rut (at the end of the rainy season) the bull will tirelessly protect his herem of cows, preventing other would-be suitors from approaching. Bellows and snorts (which sound like “gnuuuu”) are issued, ground is plowed with hooves or horns, and if all that display doesn’t work, charges and horn thrusts are exchanged.
There’s never a dull moment in Africa.
