 in January 1855, at Scarborough [Zool. 1855, p. 4631 ; and 

 Yarrell, iii. p. 349), was examined by the late J. Hancock, 

 and found to be a female Pochard.]

 Clangula glaucion (Z.). 



Winter visitant, immature birds not uncommon in some seasons 

 adult males rare. Occurs on inland waters in considerable flocks.

 numerous on the river Hull, and in immature plumage is
