 to India and Burmah. Casual Japan, reported Iceland. 



[Note. — A male example of Baer's Dtjck, Nyroca nyroca baeri (Anas 

 [Fuligula] Baeri Radde, Reise S. v. 0. Sibirien, n, p. 376, pi. 15, 1863— 

 S.E. Siberia), was obtained on Tring Reservoirs (Herts.) on Nov. 5, 1901 

 <N.C. Rothschild, Bull. B.O.C., xn, p. 25), and another on the Trent (Notts.) 

 about mid-April, 1911 (J. Whitaker, Brit. B., vn, p. 268). These may have 

 been wild birds but since " water-fowl " are sometimes kept in semi-captivity 

 without even being properly identified it seems inadvisable to admit this 

 duck to the list. It breeds in east Siberia and is found on passage and in 

 winter in Japan and China and irregularly in Burmah and India.
