Babbling Baby Bats Sound Eerily Similar to a Human Baby

When Ahana Fernandez and her colleagues wander through the Central American jungles, they listen for a peculiar sound: high-pitched, incessant chirping and squeaking. Greater sac-winged bat pups are making the noises (Saccopteryx bilineata). Despite the fact that they don't sound anything like human newborns' babbling, the animal behavior researcher and her colleagues at Berlin's Museum of Natural History (MNH) felt there was something in common between the two.
