A single individual of this species, supposed to be a young female, of which the above is a description borrowed from Selby, was killed near Yarmouth in Norfolk, in the Winter of 1829. It is a native of North America, and had never before been seen in Europe. According to Latham, appears at Hudson's Bay as a summer visitant at the end of May, and builds close to the lakes. Nest composed of grass, lined with feathers from the breast. Eggs four to six in number. Frequents fresh waters.
