Grief swans in and around Germany

The 1.2 meter long Black Swan is one of the species of swans and is mainly distributed in Australia and New Zealand and is therefore even today the official emblem of Western Australia and is also represented in the national flag. He did not come until the end of the 18th Century and is now spreading to Europe thanks to successful rearing of young in the wild in small populations in the Dutch inland seas and the Dutch coast, while in Germany only about 50 examples to live in freedom and are distributed nationwide. It breeds in Europe nor in winter, as there are his cousins ​​lived in Australia and is robust to relatively low temperatures. Often also managed the rearing of boys Black Swan in captivity, which makes it easy to hold funeral swans.

The Black Swan feeds mostly on algae and aquatic plants, but also from near-shore or grass seeds such as corn. Its appearance is similar to the Mute Swan: He has an s-shaped neck and arched wings, in contrast to the Bewick's swan species. For mourning, the black swans plumage with white wings, a red iris, the gray leg color, and their bright red beaks, which have a white transverse band at the top, typical. Grief swans prefer the temperate and subtropical climates and come in huge swamp areas and among other things, during the breeding season of non-periodically falling dry fresh and brackish waters or inland lakes before. However, smaller water bodies whose water level during the year are still on is not constant, used for breeding. Outside the breeding season are also mourning swans in rivers, where they avoid strong currents or wave action at all times. Grief swans are among the more solid social animal organizations, as both parents to take care of the breeding and rearing young. On average, these 4-8 pale green eggs hatch about 34 - 37 days, until the gray-brown swan hatch chicks. Then they are brooded by the parent in the back parts of feathers and carried around. The young birds have only this gray-brown plumage, the feathers have black tips. The male mourning swans are difficult to distinguish from the female. Only the larger form and the more stretched the neck and hold it's possible to identify a male. Grief swans are in contrast to many other species of waterfowl and migratory swans no. They keep life within a radius of 100 km and leave at certain points only drastic changes in their abiotic environment, and if they feel, for example by noise, disturbed.
