The Bena and the Hamar tribes look similar, and are sometimes referred to as the Hamer-Bena. They occupy the woredas, or administrative regions, of Ethiopia along the Kenyan border. The members of these tribes are often semi-nomadic pastoralists. This means they may migrate every few months following their herds of cattle.

Villages, which are sometimes temporary, may consist of up to 20 huts around a communal area, with pens for the cattle and goats. The Hamer-Bena tribes often do not grow crops, so trade meat and skins with their neighbours for staples such as sorghum.

Among these tribes, young men progress to manhood in a ritual known as cattle-jumping. The ritual is much as it sounds. Several young men hold a neutered bull, while the adolescent undergoing his rite of passage tries to leap over it. Four successful jumps and he's a man.

Women in these tribes may use butter to dress their hair.

These tribes are serious about cattle. Each man has three names -- a man name, a goat name and a cow name -- and there are nearly 30 words to describe variant types of cattle.
