24. American Scoter (163. Oid^mia americclna). — A large, 

 northern, winter, black duck, with the upper parts slightly 

 iridescent and the lower parts slightly brownish. The bill of 

 the male has a peculiar hump back of the nostrils, which is 

 lacking in the female. The female is dusky-brown in color, 

 lighter below, with some dull white about throat, lower part of 

 head, and belly. This and the next two species, popularly 

 called " coots," are very poor food for man, being extremely 

 "fishy." All these scoters are alike in habits, living mainly 

 at sea, over beds of bivalves, for which they 

 dive. (Black Coot.)

those on the oulmen. This is the best feature by which to 

 distinguish this scoter. The female (also the male and young 

 in winter) is sooty-brown, lighter and grayer below, with 

 white speculum, and more or less of whitish spots on the head.
