Grays Harbor and Jefferson Counties and on the outer islands. Carl 

 Lien's notes, from Destruction Island, give it as a " common winter 

 resident. A flock of probably 50 spend the winter. Nearly always 

 found in company with turnstones and surfbirds, and together with 

 these birds confine themselves entirely to the reefs." 



DISTRIBUTION 



Range. — The northeastern corner of Siberia, west coast of Alaska 

 and adjacent islands, including the Aleutians, south (rarely) to 

 northwestern Oregon. 



Breeding range. — The breeding range of the Aleutian sandpiper 

 extends north to eastern Siberia (Emma Harbor) and Alaska (Cape 

 Prince of Wales). East to Alaska (Cape Prince of Wales, Colville 

 River, and Port Moller) ; and the Shumagin Islands. South to the 

 Shumagin Islands; the western part of the Alaskan Peninsula 

 (Muller Bay and Morzhovia Bay) ; and the Aleutian Islands (Una- 

 laska, Atka, Tanaga, Kiska, Agutta, and Attu Islands). West to 

 the Aleutian Islands (Attu) and eastern Siberia (Emma Harbor). 

 The species also has been detected in summer at St. Lawrence and 

 St. Matthew Islands and at other points on the mainland of Alaska 

 (Point Dall, Pastolik, St. Michael, Nulato, and Port Clarence). 



Winter range. — Resident throughout much of its range, but also 

 south in winter, along the Alaskan and British Columbian coasts 

 and as far as Washington (Destruction Island). 



Migration. — The migrations performed by the Aleutian sandpiper 

 are very limited. In the vicinity of St. Michael, Alaska, flocks will 

 appear as early as August 15, occasionally remaining until October 

 15. They have been noted on the Asiatic side of Bering Sea at 

 Providence Bay in June, at East Cape in July, at Plover Bay in 

 September, and on Bering Island as late as October 24. 



Spring migrants have been observed to reach Point Etolin, Alaska, 

 as early as April 8 and Bering Island April 24. Spring departures 

 from the southern part of the winter range have been noted as late 

 as : Destruction Island, May 1 ; Forrester Island, May 7 ; and Ad- 

 miralty Island, May 14. An early fall arrival at Craig, Alaska, is 

 August 6 and at Destruction Island October 1. 



Casual records. — This species has been collected or observed out- 

 side of its known normal range on a few occasions : Washington, 

 Point Chehalis, November 6, 1917, and Dungeness Spit, March 4, 

 1916; Oregon, Cape Meares, December 31, 1912, and March 18, 1913; 

 these may prove to be regular winter resorts. 



Egg dates. — Alaska: 18 records, June 3 to July 24; 9 records, 

 June 15 to 22.
