Very little is known of this extremely rare species, which was first described by Pennant from a male specimen taken in a decoy in 1771. Two other individuals, a male and female, occurred near Maldon in Essex, in the Winter of 1812-13. These last, which are described in the Linnsean Transactions by Mr Vigors, are now in the Museum of the Zoological Society. Habits and nidification unknown. Stated by Pallas to be a native of Siberia, frequenting Lake Baikal and the River Lena.
