Black Swan (Cygnus atratus)
The black swan (Cygnus atratus) is a large waterbird, a species of swan which breeds mainly in the southeast and southwest regions of Australia. Within Australia they are nomadic, with erratic migration patterns dependent upon climatic conditions. Black swans have one of the longest necks of all swan species relative to their size. They have a wingspan of 6 feet or more, and a maximum weight of 20 pounds. These graceful birds commonly use their long wings in territorial or aggressive displays. . Black swans were introduced to various countries as an ornamental bird in the 1800s, but have escaped and formed stable populations. A small population of black swans exists on the River Thames at Marlow, on the Brook running through the small town of Dawlish in Devon (they have become the symbol of the town), near the River Itchen, Hampshire, and the River Tees near Stockton on Tees.
