Resumen de Call of the crybaby.
The article discusses research by biologists Susan Lingle and Tobias Riede. Lingle and Riede treated herds of mule deer and white-tailed deer on a farm in Canada to modified recording of the cries of a wide variety of infant mammals, including elands, marmots, and fur seals. The team discovered that mother deer approached the speaker as if they were searching for their offspring as long as the recording's fundamental frequency was similar to that of their own infants' calls.
