As seen by the above references, the dispersion of this teal in the 

 West is very general ; it being found at varying seasons from the Rocky 

 Mountains to the Pacific, and as far north as the Columbia River. In Utah, 

 I learned from good authority that it breeds in great numbers, especially in 

 the marshes of Utah Lake; making its appearance there in spring later 

 than most of the ducks, while its departure south takes place at an earlier 

 period than any other species. None remained at the lake in November. 

 In Southern Colorado, it was breeding in June ; though I did not succeed in 

 finding any nests that I could with certainty refer to this species.

During the migrations, the Shoveler occurs in abundance through the 

 Middle and Southern Regions, frequenting the ponds and lakes ; while with 

 the Teal it will often be found in the smallest sloughs, in fact wherever it 

 can find an abundance of the minute insects and crustaceans, which its curious 

 bill, with its net work of fine lamellae specially adapted for this purpose, 

 enables it to sift out from the water. Many appear to move well to the 

 northward in search of breeding grounds ; and Dr. Coues has fixed the fact 

 of its breeding in Dakota by finding the scarcely fledged young on the 

 Mouse River. It was a rather common species in Southern Colorado at the
