Washington, rare W. V. Long Island, common T. V., Nov. 1 to May 15 ; 

 a few winter. Sing Sing, A. V. 



Nest, of grasses, moss, etc., lined with down, on the ground. JEggs, four, 

 smooth and creamy white in color, 2-70 x 1-80 (Saunders). 



" Its manner of flying is different from that of the Canada Goose — 

 moving in more compact bodies, less rapidly, and without seeming tc 

 have a chosen leader — that marked characteristic in the flight of the 

 latter. 



" While in our bays it appears inactive, seldom taking to -vfing un- 

 less disturbed by a passing boat or the near report of a gun. 



" The Brent rises slowly, and when on the wing moves sluggishly 

 for a short distance, and, if not attracted by a distant flock, frequently 

 returns to the place it had left. Its food consists of a marine plant 

 {Zostera marina), commonly called 'eel grass.' At low water it is 

 seen industriously at work tearing up its favorite plant. After the 

 tide has risen to such a height as to compel it to relinquish its voca- 

 tion, it is seen drifting with the current, feeding sumptuously on the 

 fruits of its labor " (Giraud). 



174. Branta nig^cans {Lawr.). Black Beant. — Bears a general 

 resemblance to the preceding species, but may be readily distinguished by its 

 much darker lower breast and upper belly, which are nearly as dark as the 

 back, and by having white markings on the front as well as on the sides of 

 the neck.
