Rose-ringed Parakeet

Rose-ringed Parakeet (Psittacula krameri )

The Rose-ringed Parakeet (Psittacula krameri ), also known as Little Alexandrine Parakeet, is the most widespread species of parrot. It occurs both in Africa and in Asia. As neozoon he lives in Europe and North America.

Subspecies

There are four generally recognized subspecies:

• African Ring-necked Parakeet (Psittacula krameri krameri ) Scopoli, 1769
• Neumann's Rose-ringed Parakeet (Psittacula krameri borealis) Neumann, 1915
• Indian Ring-necked Parakeet (Psittacula krameri manillensis ) Bechstein, 1800
• Abyssinian Rose-ringed Parakeet (Psittacula krameri parvirostris ) Souancé, 1856

In addition, there are domesticated and Neozoenformen, which are a mixture of several sub- types, especially from Psittacula krameri borealis, Psittacula krameri manillensis and Psittacula krameri krameri.

Appearance

The Rose-ringed Parakeet is predominantly green, on the head, belly and under the wings yellow-green, neck, and back show in adult males depending on the subspecies a more or less pronounced blue cast. The adult males have a characteristic " collar ", which begins as a black strip under the chin and turns into a pink halter neck. He's depending on the subspecies a dark red to coral red upper beak and a red to blackish lower mandible. The tail feathers are dark green above, the average blue-green, and yellow below. Also striking is the orange - red Lidring which surrounds the eye with a bright iris. The total length of the bird with tail is about 40-43 cm, with the tail accounts for slightly more than the length of the body.

Original dissemination

Ring-necked Parakeets come in four subspecies. The natural range of the African subspecies Psittacula krameri krameri extends into Africa from Senegal and Guinea in a broad band through the Sahel to southern Sudan, where the range of the second African subspecies, P. k parvirostris, through Ethiopia to Djibouti and Somalia joins. In Asia, the subspecies P. borealis and P. manillensis live k k in an area that includes the entire Indian subcontinent and Pakistan, Bangladesh, Myanmar and Sri Lanka.

Neubürgertum

As new residents ( neozoon ), which was able to build stocks from captivity refugees, it is increasingly found in urban areas of the northern Mediterranean countries synanthropic. Alexander the Great brought him more than 2300 years ago from Asia to Greece, hence the name " Alexander parakeet ". In addition, you can find him in the Paris region, in the larger cities of Belgium, the Netherlands and the south and east of England, where he has been known since the 1930s. Between the 1970s and 1990s, there were two in Austria breeding settlements in Vienna Türkenschanzpark and the Innsbruck garden. In addition, there are naturalized occurrence in the United States, South Africa and Japan.

In Germany occurred in 1969, the first Ring-necked Parakeets in Cologne; now (2011) live there an estimated nearly 2000 copies. Other independent occurrences are located along the Rhine, particularly in Dusseldorf, Wiesbaden (along with Mainz 2011: 1500 animals in the summer at the sleeping place ), Worms, Mannheim / Ludwigshafen ( sleeping place Ludwigshafen - from presumably with parakeets from Worms, Frankenthal and the few animals the Rhine -Neckar area in summer 2011: 1640 animals) and Heidelberg. Based on these new populations formed in Bonn, Mainz and Speyer. The colonization of the Rhine-Neckar area began from the year 1973. The first sightings in Frankfurt am Main date from the year of 2012. Was in Germany in 2006, the inventory of 6000-7000 individuals and 650-880 breeding pairs. For 2011, the stock size for Germany is given as 7,500 animals and 1,500 breeding pairs.

In Germany, the Rose-ringed Parakeet nests in caves especially like old tree stocks, as they occur in parks, cemeteries and large gardens. He preferred plane trees, which he uses as a sleeping trees. For several years, breed necked Parakeets, v. a in Heidelberg, in the polystyrene layer of the outer facades heat- insulated buildings. About the impact of the presence of the collar parakeet is not yet sufficiently known. It is feared above all competition with other cavity nesting birds and Nahrungskonkurrrenz with other fruit-eating birds, and also noise pollution and Verkotung below ground beds. In early summer attract the animals in flocks of about 10-30 copies while foraging through the urban area and the area of ​​fruit trees around.
