THE American Teal (Anas Carolinensis, Gmelin) is a very 

 rare abnormal autumn migrant to the British Islands, and 

 is found inhabiting North America, migrating south in winter. 

 The adult has the scapulars pale slate-grey, and a broad 

 white crescent on each side of the breast.

THE Blue-winged Teal (Anas discors, Linnaeus) is an ex- 

 ceedingly rare straggling autumn migrant to the British 

 Islands, whose claims to be included in the British list are 

 very doubtful. It is found inhabiting the Central and 

 Southern Nearctic Region. The adult male of this teal 

 can readily be distinguished from its allies by a white 

 crescent between the eye and the bill, and by the con- 

 spicuous blue wing-coverts.
