Watch a Young Elephant Make a Surprising Railroad Crossing

A young elephant delicately lifts the barrier blocking the railroad tracks in India's Chapramari Wildlife Sanctuary and slips under. Once across the tracks, it gingerly steps over another obstruction. "It looks as though this elephant has done this before," says Joyce Poole, an elephant behavior expert and co-founder of Elephant Voices. Elephants have long been famous for their smarts--they have long-term memory, can use tools, and maintain complex social groups. But increasingly, elephants are being recognized for their problem-solving abilities.
