Collar parish conquer South Hesse: A colorful winter full of sightings!

Collar parish conquer South Hesse: A colorful winter full of sightings!

The colorful collar parish, also known as the "small AlexanderSittich", have established themselves along the rivers Rhein and Main in the wild and are now increasingly spreading in Darmstadt and Südhessische Bergstraße. According to hessenschau.de reporting this papery type from Frankfurt since 2012, but the current trend shows one striking increase in observations. While only 8 sightings in the Darmstadt-Dieburg district were registered in the previous year, 61 sightings lasted this winter-an increase of over 700 percent.

In Darmstadt itself, a swarm of about 20 collar parents in Eberstadt was sighted. Figures from Hessen indicate a total of 639 sightings this winter, whereby Wiesbaden stands out as a hotspot with 359 sightings, followed by Groß-Gerau with 78 and Frankfurt with 67. However, the actual number could be up to 6,000 copies.

origin and spread

The collar paratted originally come from Africa and Asia, were brought to Greece by Alexander over 2300 years ago by Alexander. In the meantime, the species have established themselves as neozoon in Europe, North America, South Africa and Japan. In Germany, an estimated 8,500 wild collar parish live, with a particularly large number of in cities such as Bonn, Cologne, Düsseldorf, Wiesbaden and Heidelberg. You prefer breeding sites in caves of old trees, parks, gardens and even in heat-insulated buildings, such as bonner Umweltzitung.de reported.

The collar paratted are under species protection and must not be killed for no special reason. Despite their popularity and variety of colors, however, they cause noise and pollution. Interestingly, some birds show crippled feet due to frost, which indicates the challenges that they face in the previous adjustment phase.

The problem of invasive species

The green light for the settlement of such neobiota also brings concerns. In Germany there are a total of 808 established neobiota species, including 319 animal species. 59 of these species are considered to be invasive, which means that they can potentially pose problems for biodiversity. A little optimistic view: According to the Federal Office for Nature Conservation, most of the non-regional species in Germany are not a significant danger to domestic nature. The collar parasites are classified as potentially invasive, and like Notes, the BFN checks the possible recording of this type in the black list of invasive species.
