THE GADWALL, or Grey Duck, as the term is intended 

 to imply, is a rare species, occurring sometimes in winter, 

 but more frequently in the spring, rather than at any 

 other season of the year, and then only in very limited 

 numbers. Montagu mentions that during the many years 

 he devoted to observing and collecting British Birds, he 

 was never able to obtain a recent specimen. Examples 



Genus Chauliodus of Swainson, 1831.
