Squirrels

Anyone who has ever seen a squirrel dart across a crowded street has wondered if they are aware of the danger. It turns out they may be — but if there is food on the opposite end of the street they may not care. Squirrels are fast learners, according to a recent study from Science Daily, and they learn from their peers. Stealing food is a trick that squirrels pass along.
