The adult male is all black with a white crescent under the eye, white secon- daries and a bill coloured in bright reds and black. The female has two vague light spots on the cheek like the Surf Scoter, and the feathering of the cheeks encroaches upon the sides of the bill nearly to the nostrils and about as far as that of the crown. Surf Scoter, Oidemia perspicillata. Plate I, Figs. 3, 3a. The adult male is an all black bird with small white patches on the fore and hind crown. In some changing or moulting plumages this latter is lost wholly or in part but its position and outline can still juvenile male at an early age and before other sex- ual characters are assumed. THE EIDERS. Adult male eiders are easily distinguished from similar scoters by being colored in large contrasted masses of black and white, the latter variously suf- fused on face, fore and under parts with delicate nile-green, pale slate-blue or vinaceous (pinkish). Comparable scoters are nearly solid black, relieved only by restricted, sharply defined patches of pure white about head and on wings. Female eiders are colored with mixtures of black, brown, ochre and rusty in various proportions, tend- ing towards fine streaks on face, coarser ones and V-shaped markings on back and broken bars across breast and flanks. The cross barring across the up- per breast of the females is sufficiently distinctive of the eiders to separate them from any other duck.
