HABITS. 
The Brant Geese, unlike the Canada, appear to prefer the coast to the interior when 
migrating, insomuch so that they will seldom pass over any large tract of land, but will 
follow the sinuosities of the shore, nearly always keeping over the water. These fine 
birds are particular favorites with sportsmen, and many are shot from points of land which 
make out into the sea, by building blinds, in which the sportsmen conceal themselves, while 
the wary Brant are induced to alight near, by using decoys of the same species. Mr. W. 
B. Dowse who has frequently shot over these decoys, informs me that they become quite 
tame and very intelligent, not only endeavoring to induce their wild brethren to alight near 
them, but when a number are gathered about them, they will moye to one side, in order 
to give their master an opportunity to shoot the wild Brant. I never saw a Brant Goose 
in Florida and think they seldom get as far south. In time of migration and in general 
habits, these birds resemble the Canada Geese. 
GENUS IV. ANAS. THE FRESH WATER DUCKS. 
Gen. Ch. Bill, wide, flattened, not swollen nor very high at base, nor expanded at tip. Legs, rather short. Marginal 
indentations, nearly closed in adult. 
The trachea is without dilatation but the larynx, in the male, is provided with a bony frame-work and is much ex¬ 
panded. Stomach, muscular. Sexes, not similar. There are two species within our limits.

Sr. Ch. Form,robust. Size,large. Tips of upper tail coverts, turned upward in males. Color. Adultmale. Head,

and quite black on rump, until it ends in the velvety upper tail coverts which show greenish reflections. Scapularies, red¬

brown. Tertiaries, hoary, edged with whitish. Secondaries and primaries, brown, the former rather broadly tipped
