Guessing that they might be locating their seed stashes based on their position with respect to other objects on the ground, Kamil buried seeds halfway between two conspicuously colored pipes in a large testing space. The birds found the seeds. Then Kamil moved the pipes farther apart, moving the seeds to the new half-way point. Sure enough, the birds went right to the new location, even in five different trials! What Does This Suggest? Presumably, in the birds’ minds, the seeds were to be found “halfway between the big pipes.” Though it doesn’t absolutely prove it, that idea in itself–”halfway between points a and b”–suggests a cognitive map in use.
