Unlike any other group of animals, all ant species are social: individual ants share the food they gather with their nestmates and as a consequence must repeatedly leave nest to find then return home it. These back-and-forth foraging trips have been studied for about century much our growing understanding strategies underlying animal navigation has come from these studies. One important strategy that use keep track where on trip is 'path integration', in which continuously update 'home vector' gives estimated distance direction nest. As path integration accumulates errors, it cannot be relied bring precisely home: such precision accomplished by using views acquired before start foraging.
