456 EWE DICK. 



top of head and nape, ring around lower neck, broadening out on back from which proceeds a longitudinal band, becoming 

 wider on back and rump, and under parts, black. Head, neck, transverse patch below black ring, sides of throat, scap- 

 ularics which are tinged with bluish, and wings, excepting primaries which are plumbeous-black, white. Bill, bluish tip- 

 ped with black, iris, reddish-brown, and feet, blue. Adult female. Ashy-gray throughout, becoming darker below, and 

 the tertiaries are hoary, while the inner secondaries are margined internally with black. 



OBSERVATIONS. 



Known by the prominent black and white colors as described. Formally distributed in winter from New Jersey, 

 northward, and bred in the far North. At present, very rare everywhere.

 1-65; tarsus, 1'55. Longest specimen, 23'75; greatest extent of wing, SO'OO; longest wing, 9'25; tail. 3'75; bill, T75; tarsus, 

 1-60. Shortest specimen, 20'00; smallest extent of wing, 29'30; shortest wing, H'80; tail, 3'50; bill, T50; tarsus, 1-50. 



HABITS. 



The Labrador Duck has, within the last fifteen or twenty years, become so rare as to 

 be considered nearly extinct. I saw a Duck in Plumb Island River, some five or six win- 

 ters ago, which I was confident was this species, but was unable to procure it; and I nev- 

 er saw another, nor can I. learn that any have been taken on our coast of late years. I 

 hear upon good author! ty, however, that one was procured at Grand Menan, three years 

 nince, in winter. This latter named locality appears to have been the strong-hold of the 

 species in the not very distant past, and numbers have been secured there. In habit, this 

 Duck resembles other Sea Ducks, feeding largely upon mollusks which are procured by 

 diving. At present, the Labrador Duck is a great desideratum in collections, there being 

 but few specimens in the country.

Known by the peculiar fleshy process projecting backward at base of bill, large size, and colors as described. Distrib- 

 uted in summer from Grand Menan, northward; wintering from New Jersey, northward.

DESCRIPTION OF NESTS AND EGGS. 



Nests, placed on the ground near water, composed of sticks, weeds, down, etc. Eyys,R\x. to ten in number, ellipitcal 

 in form, and ashy-green in color. Dimensions from 1'98 x 2'82 to 2- 10 x 3'20. 



HABITS. 



The well known Eider Ducks are found off our coast in winter in considerable num- 

 bers, especially in the waters of the sounds on the southern shore of Massachusetts. Thoy 

 leed principally upon mollusks, and being quite largo birds, swallow good sized bivalves, 

 several species of which I have frequently taken from their stomachs. I found these birds
