Lake.) Though eventually the species may be found 

 breeing in Alberta, at present there seems to be no cer- 

 tain nesting record for the entire Rocky Mountain chain 

 from New Mexico to Alberta. West of the Rockies the 

 riqg-necked duck seems to breed in small numbers from 

 Fort Klamath, Ore., to southern British Columbia (Cari- 

 boo District.) It is said to breed also on the Near Islands, 

 Alaska.

• Breeding Range. — This is one of the more northern- 

 breeding ducks, but its choice of hollow trees as nesting 

 sites prevents the extension of its breeding range into the 

 treeless Arctic regions, to which it seems well suited by 

 its hardy constitution. It has been noted north to Un- 

 gava Bay, Labrador; Fort Churchill, Hudson Bay, and 

 Fort Good Hope, near the mouth of the Mackenzie River. 

 It is probable that the species breeds in the heavy timber 

 nearest to these places. In Alaska it breeds commonly in 

 the interior about as far north as the Arctic Circle, but is 

 very rarely seen on the coast. The species breeds from 

 Newfoundland to British Columbia, north to the Noatak 

 River, but the breeding range extends only a little into 

 the United States, to southern Maine (Calais, Magallo- 

 way River), northern New Hampshire (Lake Umbagog), 

 northern Vermont (St. Johnsbury), northern New York 

 (Adirondacks), northern Michigan (Neebish Island, 

 Sault Ste. Marie), North Dakota (Devils Lake), Mon- 

 tana (Flathead Lake) and in British Columbia so close 

 to the southern boundary that the species will probably 

 be found to breeA in northern Washington.
