A Dutch scientist has uncovered outdated recordings of a musk duck mimicking the phrase, “You bloody idiot!” – learnt when it was raised by people in an Australian fowl park.
Leiden College scientist Carel Ten Cate stated that what was fascinating in regards to the vocal expression of the waterfowl, nicknamed “Ripper”, was not a lot the message, however that he may imitate people in any respect.
“It is undoubtedly based mostly on the human voice, although the pronunciation is a bit odd – which could be the Australian accent, I do not know,” stated Ten Cate, who revealed his findings within the Netherlands’ Philosophical Transactions of the Royal Society organic analysis journal.
Vocal studying is a uncommon trait in animals. Musk geese raised in captivity imitate the sounds they heard as hatchlings.

He stated at first he had puzzled whether or not the recordings, made within the Eighties, may very well be a hoax, however they have been made by dwelling ornithologist Peter Fullagar, who co-authored the paper. The recordings had been saved in a sound archive and referenced sometimes till Ten Cate rediscovered them in the middle of his analysis on vocal studying in birds.
Ten Cate stated Ripper had a bit extra in his repertoire – he may additionally make a noise just like the sound of a door closing and its latch clicking.
Some species of animals, and notably birds akin to parrots and songbirds, are able to mimicking human speech. However the phenomenon is uncommon – if considerably extra frequent in animals raised by people.
“To discover a species fairly exterior these teams…in a duck, that is fairly extraordinary. So it is an impartial evolutionary prevalence of the power for vocal studying – that is very particular,” Ten Cate stated.
