MASKED DUCK. 

 Nomonyx dominicus (Linn.). 



The adult male, in full plumage, neck all around, 

 back and sides, dark cinnamon-brown, the back and 

 sides with the feathers broadly streaked with black ; the 

 front of head, including chin, cheeks and crown, black, 

 this color extending nearly to the back of the head. The 

 lower parts are rusty, but the feathers of the side are 

 streaked with black. The wings are brownish-black, 

 with a white speculum. The under tail-coverts are 

 brownish, spotted with black. The tail is dark brown ; 

 the bill blue, and feet blackish; length about 15 inches. 



The female has the head black, with one or two 

 brownish streaks running back from the bill. The 

 chestnut is paler, verging to yellowish, and spotted 

 with black; the sexes are thus much alike, but the 

 female is very much duller.
