In 1987, a Researchers in Australia have recorded a male musk duck named Reaper that produces a voice that sounds a lot like “you’re a bloody fool”, with a door and a soft squeak. A second duck was recorded in the region in 2000, mimicking the call of a Pacific black duck. Both recordings have survived, but they have not been analyzed in any detail, and most of the accompanying records were destroyed in a devastating fire in 2003 through the Tidbinbila Nature Reserve.
Now retired, that lead researcher, Peter J. Fulger, teamed up with biologist Carroll Ten Kate of the University of Leiden in the Netherlands to make the first in-depth analysis of those recordings. That analysis confirms that Ripper’s distinctive voice is indeed an imitation প্রথম possibly the first widely documented example of being able to mimic the sounds of a musk duck. The researchers described their findings in a new study published in the journal Philosophical transactions of the Royal Society b, Is part of a special issue of vocal education between animals and humans.
Definitions of so-called vocal-producing education may vary, but if an isolated animal produces a voice that deviates sharply from species characteristics or is able to mimic the sounds of another species, they are considered evidence of occurrence. Learning voice-production is important for human speech and language development, but there are a few confirmed reports of this among animal species বিশেষ especially whales, dolphins, bats, elephants, songbirds, parrots, and hummingbirds.
Musk ducks get their name from the pungent odor produced by males during mating. Males are usually three times larger than females and play a large, black lobe at the bottom of the bill that may be in a glossy or “targeted” state. In the male mating display the tail can be raised and lowered and the legs can be kicked sideways and back to create large splashes in the water. Men are also known to create whistling vocalizations and show their torpedo lobes to attract women. The musk duck is the only surviving member of their particular family and is remotely related to other birds capable of mimicking sound by their voices.
Males are so aggressive that musk ducks are rarely born in captivity, but rippers were the exception. She hatched from an egg in September 1983 at the Tidbinbilla Nature Reserve, southwest of Canberra. A feather hen performs brooding duty for the eggs, but after the eggs hatch, the reaper is fed isolatedly by human handlers.
When he was a few weeks old, the reaper was transferred to a small pond with other captive-kept waterfowl and later placed in a small pen hidden from public view by the bushes. According to the authors, this pen was divided into two layers, which were connected by a hole below the water level. Two female ducks from another reserve can fit through the hole, but the reaper cannot. The women were next door when the rapper made his legendary voice.
July 1st and 2nd July, July 17th and 1st July, Fulkira recorded the Reaper via Sony Walkman Professional Cassette Recorder and Sennheiser MKH 161 micro microphone, when the Musk Duck was years old. Voices included a slamming-door sound (Hook hook hook) Duplicate the opening and closing of the egg-hanging spring door where the reaper was kept for the first few weeks after the egg was released. Sometimes there is a soft murmur after the word slamming-door which sounds like speech but there is no clear sound. The most striking voice sounded as if the rapper was saying, “You bloody fool!” – was recorded when Fullagar was nearby “because it was a way to get angry [Ripper] On display, “the authors wrote.
The recordings were preserved in the Australian National Wildlife Collection but did not catch the eye of researchers for decades until ten cats heard about them. “When I first read it, I thought, ‘It’s a hoax, it can’t be true,'” said Ten Kate. Guardian. “But it has been proven true.”
