This, the most beautiful of all our Ducks, is pretty abun- 

 dantly distributed through New England in the breeding 

 season. Wilson's description of its habits is so much 

 better than I can give, that I make a liberal extract from 

 it. He says, — 



" The Summer Duck is equally well known in Mexico and many 

 of the "West India ^-i^e^ ^^^"^ 



Islands. During the 

 whole of our winters, 

 they are occasionally 

 seen in the States 

 south of the Potomac. 

 On the 10th of Janua- 

 ry, I met with two on 

 a creek near Peters- 

 ourg, in Virginia. In 

 the more northern dis- 

 tricts, however, they are migratory. In Pennsylvania, the female 

 usually begins to lay late in April, or early in May. Instances
