 There are twenty-one species of antbirds that participate in "bivouac checking", which is a specialized behavior allowing for the antbirds to assess the "Eciton burchellii" colony's foraging activity and current location.This allows the antbirds to reduce the time spent tracking a colony that is not foraging.Through bivouac checking, the antbirds might be remembering the correct location of colonies and returning to them at the appropriate time in the colony's foraging cycle.
