FLORIDA DUSKY DUCK. 



Anas fidvigula Ridgw. 



The general color above is brownish-black, as in the 

 black duck, but the feathers more widely margined 

 with yellowish, giving a generally paler cast to the 

 bird. The chin and throat are always plain unstreaked 

 buff, these being finely streaked in the black duck. The 

 speculum is green, sometimes tipped with white, which 

 may then form a bar across the wing. The bill is olive- 

 yellow and there is a triangular spot of black at its 

 base, near the angle of the mouth. The legs and feet 

 are orange-red. The length is about 20 inches and 

 the wing 10. The female is somewhat paler than the 



male.
