DR. GAMBEL ON THE BIRDS OF CALIFORNIA. 225 



150. R. AMERICANA, Linn. Red-necked Avocet. 



We found this species common in crossing the interior. 



~ CY GNV S, Antiq. 



151. C. AMERiCANUs, Sharpless. American Swan. 



Not uncommon during the winter season in the retired lakes and ponds of 

 California. 



CHEN, Boie. 



152. C. HYPERBOREUS, Boic. Snow Goose. 



Extremely abundant in California during winter, the plains often being white 

 with them for miles in extent. 



ANSER, Antiq. 



153. A. ERYTHROpus, Linn. White-fronted Goose. 



Abundant. The large irregular black patches or bands on the lower part of the 

 breast of this species, is a curious character, and, from their being so irregular in 

 shape, would seem to be in immature condition; but among the myriads of Geese 

 which arrive in California in the fall and retire again early in the spring, perfectly 

 adult ones are abundant, yet I never saw these patches but of the same irregular 

 outline, although many flocks which seemed to be young birds had no trace of such 

 marks. 



154. A. CANADENSIS, Vieill. Common Goose. 

 Very abundant. 



155. A. HUTCHiNSii, Richard. Hutchin's Goose. 



Abundant in California in company with the former. There is a specimen of this 

 species in the Academj-, which was procured by the late Dr. Burrough at Vera Cruz. 



BERNICLA, Antiq. 



156. B. BRENTA, Steph. Brant Goose. 

 Abundant. 



ANAS, Linn. 



157. A. BoscHAS, Linn Common Mallard. 

 Abundant in California. 



MARECA, Steph. 



158. M. AMERICANA, Steph. American Widgeon. 

 Extremely abundant along the coast.
