The Crested is a breed of domestic duck. It was probably brought to Europe from the East Indies by Dutch ships.[3]:413 It has its appearance because it is heterozygous for a genetic mutation causing a deformity of the skull.
History
The Crested probably originates in the East Indies, with subsequent development in Holland.[3]:413 Crested ducks are seen in seventeenth-century paintings such as those of Melchior d'Hondecoeter and Jan Steen.[7]:441
In the United States the breed was described by D.J. Browne in 1853.[3]:413[8]:197 The white Crested was added to the American Standard of Perfection in 1874; the black variant was added in 1977.[4] The Crested was recognised in the United Kingdom in 1910.[3]:413
A bantam version of the breed, the Crested Miniature, was bred by John Hall and Roy Sutcliffe in the United Kingdom in the late twentieth century; it was recognised in 1997.[3]:415
Characteristics
Apart from the crest, the Crested is an ordinary-looking duck of medium size. It may be of any colour, although in the United States only black and white are recognised; in the UK, as in several other European countries, any colour is permitted.[7]:441[5] The crest varies widely in size, from unnoticeably small to a diameter of approximately 13 cm.[9] They have long, slightly arched necks, medium length body, much depth and fullness through the breast.[10]
Though Cresteds can be good layers and have strong roasting qualities, the main interest and demand for the breed is as pets and decorations. They are not a popular show breed due to challenges associated with the crest genes also causing a fat body within the skull. Depending on the fat body's size and relative position to the brain, it can impede a duck's ability to ambulate. Many crested ducks experience a "tottering" walking pattern and, if knocked over, are unable to get up. Other issues caused by the fat body may include seizures, neurological problems, and even early death. [11]
