Wild Parrots Learning To Talk From Escaped Pet Birds
bazzalunatic writes "Be careful what you teach a parrot. Some chatty pet parrots that have escaped back into the wild have taught wild parrots to talk. Seems the phenomenon could be integrated into the flock through generations. From the article: 'The evolution of language could well be passed on through the generations, says Ken. "If the parents are talkers and they produce chicks, their chicks are likely to pick up some of that," he says. This phenomenon is not unique; some lyrebirds in southern Australia still reproduce the sounds of axes and old shutter-box cameras their ancestors once learnt.'" While this doesn't reach the amazing level of Washoe the chimpanzee teaching sign language, it is still interesting and reminiscent of something out of an Alfred Hitchcock movie.
One of Washoe's caretakers was pregnant and missed work for many weeks after she miscarried. Roger Fouts recounts the following situation:
"People who should be there for her and aren't are often given the cold shoulder--her way of informing them that she's miffed at them. Washoe greeted Kat [the caretaker] in just this way when she finally returned to work with the chimps. Kat made her apologies to Washoe, then decided to tell her the truth, signing "MY BABY DIED". Washoe stared at her, then looked down. She finally peered into Kat's eyes again and carefully signed "CRY", touching her cheek and drawing her finger down the path a tear would make on a human. (Chimpanzees don't shed tears.) Kat later remarked that that one sign told her more about Washoe and her mental capabilities than all her longer, grammatically perfect sentences."[22]
