146 



breed in upper Sylvies valley in the Blue Mountains, where I noticed 

 several specimens June 8, 1876. 



172. Fuligula collaris (Bonap.). Ring-necked Duck. 



Not so common as either the two preceding species during the mi- 

 grations, and oftener found on the deeper portions of the lake than 

 in the creeks and sloughs. 



173. Aythya americana (Bonap.). Redhead. 



Common during the migrations, and probably a few breed about 

 here. 



174. Aythya valisneria (Bonap.). Canvass-back. 

 Equally common during the migrations, and breeding in the higher 



mountain valleys in the Blue Mountains, where I found them nesting 

 on Bear Creek, at an altitude of six thousand feet. In the spring 

 and fall they frequent the shallow portions of Malheur Lake in im- 

 mense flocks, but are not so well flavored as in the east. 



175. Bucephala clangula (Linn.). Golden-eye. 

 Rather common during the migrations. 1 



176. Bucephala albeola (Baird). Butterball. 

 Common during the migrations. 



177. Oedemia americana (Swainson). Scoter. 



Not uncommon on the more open portions of Malheur Lake, but 

 very shy and difficult of approach. 2 



178. Mergus merganser (Linn.). Sheldrake. 

 Common; found in nearly every mountain stream during the mi- 

 grations. 



179. Mergus serrator (Linn.). Red-breasted Merganser. 



I believe this species breeds on Bear Creek in the Blue Mountains, 

 where I found it common in August, 1876. 



180. Mergus cucullatus (Linn.). Hooded Merganser. 

 This is the most common of three species of Mergansers, and I 



believe that it breeds here also. It is less often found in the small 

 •creeks than in the lake, where it is particularly abundant during the 

 migrations. 



181. Pelecanus trachyrhynchus (Lath.). White Pelican. 

 A very common summer resident, making its appearance early in 



1 B. islandica I have so far not seen about here, and I doubt whether it visits 

 this section. 



2 I have no doubt that several other species of sea ducks frequent the lake 

 in the spring and fall, but as most of the hunting is done on the shore, and 

 the creeks and sloughs emptying into it, they have been overlooked so far.
