The Masai who move from place to place

They move their herds from one place to another, so that the grass has a chance to grow again; traditionally, this is made possible by a communal land tenure system in which everyone in an area shares access to water and pasture. Nowadays Maasai have increasingly been forced to settle, and many take jobs in towns.

Explanation:

Unlike many other tribes in Kenya, the Maasai are semi-nomadic and pastoral: they live by herding cattle and goats. The Maasai have not fared well in modern Africa. Until the European settlers arrived, fierce Maasai tribes occupied the most fertile lands.
