Elephants have names for each other, new study finds

US scientists have discovered that elephants call to each other using their names. While dolphins and parrots are known to address each other by mimicking sounds -- elephants are the first non-human species found to create names for each other, which they express as a series of rumbles. George Wittemeyer is the chairman of Save the Elephants’ Scientific Board, a professor at Colorado State University, and a co-author of the new research. He spoke to Newshour's Tim Franks from Samburu, in central Kenya.
