QUEEQUEDULA. 



Querquedula, Stephens, in Shaw's Gen. Zool. xii. pt. 2, p. 142 (1824) ; Salvad. Cat. Birds Brit. 

 Mus. xxvii. p. 290 (1895). 



The blue wing-coverts are the leading character which distinguishes the Blue- 

 winged Teal from all the other true Ducks, except the Shovelers {Spatula), 

 and here the shape of the bill is a recognizable character. In the present genus 

 the bill is slightly wider at the tip than at the base, but is not broadened out as 

 in. Spatula. 



Of the five species of Querquedula known, one, viz. the Garganey {Q. circia), is 

 found in the Old World, and the remaining four are American, two of them occurring 

 within our limits.
