GENUS NETTION 



(Greek vtrnov, nettton, a duckling, dim. of vtrra, netta, a duck). 



Nettion, Kaup. Natiirl. Syst., 1829, p. 95. Type Anas crecca, 

 Linn. 



Bill two-thirds as long as the head, much longer than tarsus, 

 slender, slightly narrowing toward the tip; greatest width one- 

 third the length of culmen. Head not crested. 



About a dozen species of this genus are distributed throughout 

 the world, of which only one is indigenous to North America. 

 The European Green-winged Teal, a close ally and easily con- 

 founded with the North American species, occasionally straggles 

 into our limits, perhaps more frequently than is supposed, as the 

 ordinary observer would not notice any difference between them. 

 Both species go in flocks of considerable size, and have a swift, 

 erratic flight. 



KEY TO THE SPECIES.
