 There is also seasonal migration between dry-season refuges, better hunting grounds while water is more abundant, and areas with large numbers of tubers or berry trees when they are in season.If a man kills a particularly large animal such as a giraffe far from home, a camp will temporarily relocate to the kill site (smaller animals are brought back to the camp).Shelters can be built in a few hours, and most of the possessions owned by an individual can be carried on their backs.
