The Australian Museum’s Search and Discover desk, which offers a free service to identify species, has received numerous reports of encounters with talkative birds in the wild from mystified citizens who thought they were hearing voices. Martyn Robinson, a naturalist who works at the desk, explains that occasionally a pet cockatoo escapes or is let loose, and “if it manages to survive long enough to join a wild flock, [other birds] will learn from it.”Birds mimic each otherAs well as learning from humans directly, “the birds will mimic each other,” says Jaynia Sladek, from the Museum’s ornithology department. “There’s no reason why, if one comes into the flock with words, [then] another member of the flock wouldn’t pick it up as well.” ‘Hello cockie’ is the most common phrase, though there have been a few cases of foul-mouthed feathered friends using expletives which we can’t repeat here. The evolution of language could well be passed on through the generations, says Martyn. “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.
