Description: The swedish Yellow duck was first developed by Måns Eriksson in Svalöv. He did this by crossing several different breeds of ducks until he came up with this species in the early 1900s.
In 1970, They were considered extinct until a small flock were found from which today Yellow ducks originates.
History: The Swedish Blue emerged during the nineteenth century in what was then Swedish Pomerania, now divided between north-west Poland and north-east Germany; the first documented mention is from 1835. Some birds were exported to the United States in 1884, and it was added to the Standard of Perfection of the American Poultry Association in 1904 as the "Swedish", with the single color variety "blue".
The population of the Swedish Blue in Sweden consists of only 148 breeding birds; its conservation status world-wide was listed as "critical" by the Food and Agriculture Organization of the United Nations in 2007 and in 2014 was listed as "endangered-maintained" in Sweden. No data is reported from Ireland, the only other country reporting the breed. It is listed as "watch" by the American Livestock Breeds Conservancy. The Blue Swedish is not a popular exhibition breed either; specifics on wing color make the breed challenging to perfect and often discourage breeders and hobbyists from owning the breed.
