SEA DUCKS. 107 



The Pintail is frequently found associated with the Black Duck 

 and Widgeon. As a rule it is voiceless, but is said to utter "a low- 

 toned quack at night." The long neck and tail of the male make its 

 identification easy even at a distance.

 Sept. to Apl. ; rare S. R. Sing Sing, tolerably common S. R. Cambridge, 

 common T. V., Mch. and Apl. ; Aug. to Nov. ; a few breed. 



Nest, of grasses, leaves, twigs, etc., in a hole in a tree or sturnp. Eggs, 

 eight to fourteen, pale butty white, 2'05 x 1-50. 



Woodland ponds and forest-bordered streams make a proper setting 

 for the grace and beauty of these richly attired birds. Several times 

 it has been my fortune to see them in the unconscious enjoyment 

 of their secluded homes, and I know of no sight in the bird world 

 which so fully satisfies the eye. Alarm them, and with a frightened, 

 plaintive whistle, ^oo-eek" they spring from the water and make off 

 through the woods. At other times they will swim ahead of one's 

 canoe, and, rounding a bend in the stream, go ashore and walk rapidly 

 away. 



The young are brought from the nest to the ground in the bill of 

 the parent. 



Subfamily Fiiligulince. Bay and Sea Ducks. 



The members of this subfamily are to be distinguished from those 

 of the preceding by the presence of a lobe or web on the hind toe.

 coasts. Their food consists chiefly of mollusks, crustaceans, and the 

 seeds and roots of aquatic plants. They obtain it principally by div- 

 ing, sometimes descending one hundred and fifty feet or more. The
