Too often, these migrating elephants end up stuck inside communities, looking for food and water but ending up breaking open water tanks, breaking pipes and, of course, breaking into food stores for food.
In another raccoon study, researchers showed the animals that by dropping pebbles into a water tank, they could raise the water level enough to reach a marshmallow floating at the top.
A trolley car and a number of bicycles had stopped, too. Pedestrians looked in surprise at the proud pigeon disturbing the traffic. Now it perched on the water tank of the bus, tilting its neck and lifting its head high.
