00:00You know how people use a funny voice when talking to babies?
00:07Well, turns out bats do that too.
00:10Greater Sack Wing bat moms use baby talk to communicate with their pups,
00:14according to findings published in the journal Frontiers in Ecology and Evolution.
00:19Greater Sack Wing bat pups start working on their speech during the first three months of life,
00:23babbling in a way that's similar to human babies.
00:26A team including scientists from the Smithsonian Tropical Research Institute
00:30discover that moms interacted with pups as they do this,
00:33which could be seen as positive feedback during vocal practice.
00:36And moms will actually use a different pitch when talking to babies
00:40compared to when they're communicating with adults.
00:42This is the first time scientists have described a phenomenon that could resemble baby talk among bats.
00:48And it shows that social feedback is not only important during vocal development for humans,
00:52but other vocal learning species too.
