On NPR, Robert Krulwich looks at the work of scientist Karl Berg who has been studying green-rumped parrotlet, "a cup-it-in-your-hand adorable little green parrot that lives in Venezuela." Reportedly, these animals will name their young and, best of all, those names "stick for life."
Scientist Karl Berg has constructed a bunch of parrot nests on a Venezuelan ranch, and he's got mini-cams in those nests recording everything these little birds do. As you'll hear, they peep a lot.
"Most people say, 'Well, all those calls are just noise,' " Karl told Virginia Morell, but "I think they're having conversations." Berg has listened to so many parrots in so many nests for so long, he has that weeks after birth, these little birds begin to use very specific peeps to identify themselves to others. Not only that, they learn the peeping "names" of their parents, brothers, sisters, and use them in conversation, as in, "Peep-duh-dee-Peep, is that you?"
