This animal’s dogged persistence and impeccable memory have made it the nemesis of gardeners throughout its vast range. Most squirrels display an impressive array of tricks and strategies that help them survive. For starters, these clever creatures are essentially woodland animals that have adapted to living alongside humans, eating out of bird-feeders, flower gardens and whatever food might be lying around. They are also able to store and cache food for leaner times, and then find their hidden morsels many months later. They may also pretend to hide food in order to confuse potential thieves, which researchers believe shows an advanced level of cunning and intellect.
