70 PACIFIC COAST AVIFAUNA [No. i. 



CHECKLIST OF THE BIRDS OF THE KOTZEBUE 

 SOUND REGION. 



The following list Ls intended to include every species so far recorded from 

 the Kotzebue Sound region, together with the authority or authorities for each. 

 The notes on comparative abundance pertain exclusively to the summer months, 

 unless otherwise stated. 



1. Colymbus holboellii (Reinh.). Holboell's Grebe. 



Selawik Lake, point of greatest abundance (Nelson). Kowak Delta, common 

 (Grinnell). 



2. Colytnbus auritus Linn. Horned Grebe. 

 Shores of Kotzebue Sound (Nelson). 



3. Gavia imber (Gunn.). Loon. 



Kotzebue Sound and Selawik Lake (Nelson). Cape Lowenstern (Grinnell). 

 Kowak River (Townsend, McLenegan). Not common. 



4. Gavia adamsii (Gray). Yellow billed Loon. 



Not rare summer resident — about head of Kotzebue Sound; Selawik Lake 

 and the Kunguk (=Buckland) River, points of greatest abundance (Nelson). 

 Kowak River, occasionall)^ noted (Townsend); not abundant (McLenegan). 

 Noatak River, several (McLenegan). I was surprised and disappointed not to be 

 able to find this species in any of the region visited. I kept special look-out dur- 

 ing both summers, and although numbers of loons were shot and very many more 

 were seen closely enough to make identification certain, yet I never saw the 

 Yellow-billed Loon. Possibly it is becoming scarcer than formerly, for Nelson and 

 others apparently considered Kotzebue Sound to be its centre of abundance. The 

 natives use the skins of loons for clothing and "ditty-bags," and I saw a great 

 many such skins in their possession. The plumage of the head and neck is 

 particularly desirable for fancy-work. Although I examined numbers of such 

 articles among the natives from Cape Blossom up the Kowak to our winter camp, 

 I did not see a single fragment which I could identify as belonging to any other 

 than the Black-lhroated and Red-throated Loons. 



5. Gavia arctica (Linn.). Black-throated Loon. 



Abundant throughout the Kotzebue region (Nelson, McLenegan, Grinnell.) 



6. Gavia lumme (Gunn.). Red-throated Loon. 



Common throughout the Kotzebue region (Nelson, Townsend, McLenegan, 

 Grinnell). 



7. IvUnda cirrhata Pall. Tufted Puffin.

8. Fratercula corniculata (Naum.). Horned Puffin.

 Outer waters of Kotzebue Sound, fairly common (Grinnell).
