160. Branta bernicla var. nigricans (Lawr.). Black Brant. 

 Migratory and rather uncommon. I have seen several in the hands 



of Indians. 



161. Anas boschas (Linn.). Mallard. 



A common resident, breeds abundantly; found throughout the year 

 where there is open water. 



162. Dafila acuta (Linn.). Pin-tail. 

 Common during the migrations ; none remain to breed. 



163. Chaulelasmus streperus (Linn.). Gadwall. 



A very common summer resident, breeding abundantly about the 

 swampy shores of Malheur Lake. I have found perfectly fresh eggs 

 of this species as late as July 20. Its flesh is very inferior. 



164. Mareca americana (Gmel.). American Widgeon. 



A rather common summer resident, found breeding in several 

 localities. 



165. Nettion carolinensis (Gmel.). Green-winged Teal. 

 Equally common, and breeds; seems to be more partial to the 



smaller mountain streams than the large bodies of water in the val- 

 leys during the breeding season. 



166. Querquedula discors (Linn.). Blue- winged Teal. 

 Not so common as the preceding species. I doubt if any breed 



here. 



167. Querquedula cyanoptera (Vieill.). Bed-breasted Teal. 

 More common than either of the two preceding species; breeding 



in large numbers. They commence laying here about May 15, and 

 frequently their nests are placed a hundred yards or more from the 

 nearest water. 



168. Spatula clypeata (Linn.). Spoonbill. 



Not very common, but possibly breeds at Keeney's ferry on Snake 

 River, where I saw several birds of this species August 2, 1876. 

 During the winter months these birds are found in immense numbers 

 at Owen's Lake, in Inyo County, Cal. 



169. Aix sponsa (Linn.). Wood Duck. 



Very rare. A single pair were shot by Lieut. G. R. Bacon, U. S. A., 

 in the fall of 1876. 



170. Fuligula marila (Linn.). Big Blackhead. 

 Very common during the migrations. 



171. Fuligula affinis (Eyton). Little Blackhead. 



About equally common during the migrations, and I believe a few
