In 1987, a an Australian researcher recorded a male duck named Ripper making a sound that sounded like “You bloody idiot,” with a sound similar to a slammed door and a small cry. The second duck in the region was recorded in 2000 to mimic the singing of the black Pacific duck. All of the paintings survived, but did not go into detail, and much of what followed was destroyed in a fire that broke out in the Tidbinbilla Nature Reserve in 2003.
Now retired, former researcher, Peter J. Fullagar, has teamed up with Carel ten Cate, a biologist at Leiden University in the Netherlands, to conduct a first detailed study. That research confirmed that Ripper’s unique vocabulary is a form of imitation — perhaps the first recorded example of musk ducks that can mimic vocabulary. The researchers reported their findings in the form of new paper published in the newspaper Philosophical Events of the Royal Society B., part of a special issue of voice and animal and human learning.
Interpretation of the so-called vocal cords may vary, but if an animal raised on its own produces sound that is different from that of a living creature or that imitates the vocal cords of other species, that is evidence of astonishment. Vocabulary learning is essential for human speech and language development, but there have been only a few reliable reports of this in species – especially whales, dolphins, bats, elephants, songbirds, scorpions, and hummingbirds.
Musk ducks get their name from the fragrance produced by men during the day. Males are usually three times larger than females and play a black, black lobe under the bill that can be in the flaccid or “turgid” region. Men’s performances can include lifting and lowering the tails and hitting the sides and back and legs to create large waves in the water. Men are also known to whistle and blow their punches to attract women. Musk ducks are the only living species of their kind and are very similar to other birds that can mimic their sound.
Lonely Boy
The men are so angry that the musk ducks don’t like to be taken captive, but Ripper was different. They hatched from an egg in September 1983 in the Tidbinbilla Nature Reserve southwest of Canberra. The rearing hen does the job of raising an egg, but when it is over, Ripper was raised and fed by people who live alone.
Within a few weeks, Ripper was transferred to a small pond with other seabirds that were trapped in captivity and later kept in a small enclosure hidden by herds. According to the authors, the pen was divided into two parts, connected by holes under water. Two female ducks from other areas were able to enter the holes, but Ripper did not. The women were in a tight spot when Ripper uttered his voice.
Fullagar recorded the Ripper and Sony Walkman Professional cassette recorder and Sennheiser MKH 816 microphone on July 19 and 26, 1987, when the musk duck was 4 years old.whuk whuk whuk) imitating the opening and closing of a spring door hung near where Ripper was detained a few weeks after the shooting began. Sometimes the sound of the next door is followed by a low-pitched sound that sounds like a talk but without a recognizable voice. A very funny voice sounded like Ripper was saying, “You bloody fool!” – written when Fullagar was around “because that’s the way to get angry [Ripper] on display, “the authors wrote.
The photographs were kept in the Australian National Wildlife Collection but were not known to researchers for many years until Cate heard about them. “When I first read it I thought, ‘It’s a lie, it can’t be true,’ ‘Cate Ten he was told Supervisor. “But it turned out to be true.”
