Colorful intruders: Why parrots conquer our cities!

Heidelberg, Deutschland - In many German cities, they are no longer a rare spectacle: free -living parrots that fly through the air and weld around in the parks. These colorful birds have created an ecological niche, especially in cities such as Cologne, Düsseldorf, Stuttgart and Heidelberg. Between 15,000 and 20,000 copies now live in Germany, with the collar parliament being the most common representatives of this population. Your home is usually in the tropical and subtropical regions of the world, but you have successfully adapted to the mild climate along the Rhine.

The first sightings of these parrots in Germany already go back to the late 1960s when they may be out of private breeding or households.

Another important topic is the potential threat of domestic ecosystems. In countries such as Italy and Spain, there are already reports on competitive struggles between parrots and local bird species for breeding sites and food resources. The question of whether the parrots should be regarded as an invasive way concerns scientists and biologists. Andreas Jahn, a biologist and editor at the spectrum of science, gives insights into the situation in Heidelberg, where the birds even try to find nesting facades. He describes the noise of the parrots as sometimes so penetrating that you feel like in a Hitchcock film.

In a podcast in conversation with Marc Zimmer, Jahn explains the factors that contribute to the spread of the parrot population and discusses which strategies could be necessary to cope with the situation in the future. The records of the discussion are not only informative, but also offer a deep insight into a topic that increasingly focuses on the public.

For further details about the lively discussion about the parrots and their way of life, the information from spektrum.de referred. It becomes clear that the phenomenon of the free -living parrots raises many questions that require a more detailed consideration.

As part of the natural habitat in the cities, parrots have not only shown the ability to adapt to urban environments, but also exacerbated the gap between the natural observers and the everyday residents of the cities. This problem is not only limited to Germany; It could represent a sign of globally increasing conflicts between humans and animals that are caused by urbanization and climate change.
