BIRDS. 203 



well known as a bird of California, and in the course of its winter migration visits the shores 

 and lakes of Chile. 



Specimens in the collection are in very nearly the same plumage as others from western North 

 America obtained in spring, and those labelled as females differ in colors entirely from the 

 males, being as represented in the plate of our work above cited. 



This bird inhabits fresh waters ; generally observed in the smaller streams.

 This handsome Teal, though of frequent occurrence in some of the countries of South America, 

 is more rare in Chile. Specimens in the present collection are from the vicinity of Santiago.

 Notwithstanding the fact that specimens in the collection of this Expedition are labelled as 

 males and females, all the specimens of this bird that we have ever seen have the appearance to 

 us of being immature. Nor is any other plumage described by naturalists. In fact we regard 

 this bird as a species the adult of which is probably unknown, though perhaps migrating in the 

 summer to the western countries of North America. 



All the species of the group to which this bird belongs are characterized by plumage of 

 unusual beauty of colors when mature. The discovery, therefore, of the adult of this species is 

 a point of much interest, especially if added to the ornithological fauna of the United States. 

 Inhabits fresh water, and is at times abundant in Chile.

This fine Duck, a near relative of the common Pintail {Dafila acuta) of the United States, is 

 one of the southern species which are known to visit the coast of California, and probably 

 breeds in the northern regions of western North America. It is a common species in Chile at 

 some seasons.
