Some species of animals are capable of singing the most varied vocalizations. From the screaming goats to parrots capable of imitating humans, to the chilling vocalization of the common lira. But in a recent study, some researchers have identified specimens of Australian musk duck, even capable of ‘imprecare’ (saying).
The phenomenon was observed in captivity, in some specimens. One of these was Ripper, who lived at the Tidbinbilla Nature Reserve in Canberra, Australia. The specimen was able to imitate the sound of the impact of a door closed with force and a typical (and unflattering) Australian swearing, or “foul stupid.” It is supposed that he learned these sounds from the reserve keeper, denoted a remarkable ability to learn vocals.
Later in the same park another male duck, raised by a female specimen, manifested a similar behavior. He was able to mimic another kind of duck, called the Pacific german. Due to a fire, which hit the reserve in 2003, all the documentation was lost and the phenomena cannot be deepened.
Today’s research team, consisting of ethologists Carel ten Cate and Peter Fullagar, analyzed these phenomena several years ago and presented an article in which we analyze the atypical vocalizations and the evolutionary-behavioral causes that
The researchers, associating with these phenomena those of other specimens of the species that simulated human cough, said: “Together with the previous observations on the vocal differences between populations and deviant vocalizations in captive-bred individuals, these observations demonstrate the presence of This emphasizes the scholars’ strong interest in revealing the characteristics that allow these ducks to imitate a wide range of sounds.
For scholars, one of the reasons for this ability would be to associate with the vocal learning conferred by a portion of the brain, known as the telencephalus (which allows parrots to speak This brain portion would even be much more developed in aquatic species than other birds. According to researchers, “Vocal learning in musk duck would be an independent case of evolution, raising many questions ranging from neural and behavioural mechanisms involved in the evolutionary and adaptive background of voice learning in this species.”
The latter suggest a thorough study of the observed behaviour, which has never been found in any other species of ducks and chickens.
