Search strategies open a window onto the mind of navigating animals

Navigation is a great behaviour to study because the behaviour gives you a direct read out of what is in the animal’s brain. This is particularly true of search behaviours, which not only give you an read out of an animals estimate of position – but also their certainty in that estimate. Merkle and Wehner have shown that search spread depends of the length of the home vector at the start of the homeward trip rather than the total length of the outbound journey. The implications concerning an ant’s meta-knowledge during navigation are intriguing.
