There are no native parrot species in Europe. However, large numbers of natives were displaced after escaping from their owners or being released on purpose. One of them is Myiopsitta monachus, also called monk parrots (monks) or Quakers. It turns out they have unique communication methods depending on where they live, explained Stephen Tindell, lead author of the study.

Results

Monk parrots are native to South America and now live in large numbers in many European countries. Since invasive species have only recently spread into Europe and have not gone through a long evolutionary process in this region, they are an ideal object for studying how the same species varies depending on region.

• As scientists state, mostly The frequencies of the dialects differ in each cry.It is very difficult for people to hear and distinguish.
• At the same time, there were no differences between the “languages” of parrots in the same city. The researchers studied individuals who lived far away from each other in different parks and likely never crossed paths. But their “language” was the same.
• The difference was only heard between populations in different cities.

This allows us to conclude that the area where these birds live affects their communication. Since often the same species have the same means and methods of communication, it can be concluded that their dialects were already divided after their arrival in European cities.

This indicates that dialects arose as a result of a passive process (copying by birds). [інших] birds make small mistakes and therefore cities become increasingly different from each other,
– scientists write, but still do not reject the possibility that they were different from the very beginning.

The researchers also do not rule out that dialects may form as a result of an active process that helps birds in social communication, for example in recognizing group mates. In parks, monk budgies live in very crowded nests. Researchers believe that vocal differences, such as slang, may exist among these small social units. “We believe that dialects can be used as passwords to communicate between Yuva members.”– add the authors of the paper, who plan to find out how individuals learn from each other in the future.
