Picking a Route: Do Toads Follow Rules or Make Plans?
Animals move through their environment, sometimes just exploring, but more often aiming at a specific goal, such as their next meal. Frequently they will come across obstacles strewn in their path, and to a greater or lesser degree they have developed strategies which enable them to avoid falling into holes or bumping into boulders. Indeed, often they do more than just stop short at such obstacles, they detour economically round them. At times they operate in such familiar surroundings that they have learnt the appropriate path to take when going from one point to another, and there are a number of examples of animals which then continue to make detours long after the barrier which first made the detour necessary has been removed (von Uexküll, 1957).
