324 NATATORES. MARECA. WIGEON. 
The Wigeons are distinguished from the Teals by a much 
shorter and less cylindrical bill, and from the Ducks, by that 
member becoming more contracted and narrow, instead of 
widening towards its tip. The laminz of the bill are also 
broader and set wider apart, approaching in form nearer to 
those of the subfamily Anserina. These birds also vary in 
their habits, for instead of searching and sifting the mud 
with their bills for insects, seeds, &c., upon which food the 
preceding genera chiefly subsist, they live principally on 
grasses and vegetable diet, which they pluck in the same 
manner as Geese. Their flight is strong and swift, and they 
have a peculiar shrill whistling call-note. In the shape of 
the tracheal labyrinth they resemble more the Pintailythan 
any of the other species; and the middle feathers of the tail 
are also acute, and considerably longer than the rest.
