the form of small fish, water insects, worms, frogs 

 and their spawn, and anything of a similar nature

SCAUP 18 inches. Resembles the Tufted Duck in it black 

 bead, neck, upper back, and breast, white speculum and

SCAUP. Plate 95. 18 inches. Head, neck, breast, 

 and upper back black ; upper parts gray in appearance, 

 due to fine black cross-lines upon a white ground, but 

 becoming plain black towards the tail ; wings dark, 

 with white speculum, the latter bordered with brown ; 

 under parts white, except beneath the tail, where 

 black again occurs ; bill and legs gray. Female :

 the tidal flats and about estuaries, where it feeds
