Trails extend radially from edge of nest mound, with 1 m diameter. Trail is formed in a fan shaped region. Trails very day to day. Each colony chooses from up to eight distinct foraging trails. Direction varies in response to overlap with foragers of neighboring colonies. Foragers tend to travel in the direction from which most patrollers return. 2008-03-11T03:52:00Z
