PECTORAL SANDPIPER. 35 



is probably the principal breeding range. The species winters in 

 Australia and New Zealand and migrates through the Commander 

 Islands, Japan, China, and the Malay Archipelago. 



All the records for North America seem to be during the fall migra- 

 tion, at which period — crossing to America on the way to its winter 

 home in Asia — it is fairly common in Alaska on the shores of Norton 

 Sound, and has been noted north to Port Clarence and Hotham Inlet 

 (Nelson) . It has been taken a few times on the Pribilof Islands, once 

 on Unalaska Island (Bishop), once on Queen Charlotte Islands 

 (Fannm), and once on Vancouver Island (Brooks). The period of 

 occurrence on the coast of America extends from August 17, when 

 the first was seen on the Pribilof Islands (Grinnell), to October 12, the 

 date of the last seen in Norton Sound (Nelson) . The two individuals 

 taken December 27, 1897, on Queen Charlotte Islands (Fannin), 

 were probably stragglers. 



Pectoral Sandpiper. Pisobia maculata (Vieill.). 



Breeding range. — The principal known summer home of the pectoral 

 sandpiper is the coast of northwestern Alaska, from the mouth of the 

 Yukon (Nelson) to Point Barrow (Murdoch) . The principal authority 

 on the birds of the Arctic coast east of the Mackenzie is MacFarlane, 

 and he reports that the pectoral sandpiper was rare in the vicinity of 

 Fort Anderson and Franklin Bay, and that he was never able to find 

 the nest. This must have been a local peculiarity of distribution, for 

 Edward A. Preble, of the Biological Survey, found the species abun- 

 dant in August, 1900, on the barren grounds of the western shore of 

 Hudson Bay; the species is also a common fall migrant on the coast of 

 Ungava (Coues). Undoubtedly all these birds of Keewatin and 

 Ungava nest along the neighboring Arctic^ coast, where, indeed, the 

 eggs have been taken at Cambridge Bay, Franklin (Collinson) . 



Winter range. — In winter the species passes to southern South 

 America, at least as far south as Port Desire, Argentina, latitude 

 40° 30' S. (Sharpe), and to Antofagasta, Chile, 23° 30' S. (Philippi). 

 It winters in northern Argentina (Durnford) and as far north as 

 Bolivia (Salvadori) and Peru (Shaf pe) . Though confined in summer 

 to the seacoast, yet in its migrations it has been noted in Colorado 

 at 13,000 feet (Morrison), and in its South American winter home it 

 is not uncommon in the mountains to 12,000 feet (Sclater). 



Migration range. — The pectoral sandpiper has a very pronounced 

 southeastward migration in the fall. How far west the range extends 

 in the Arctics is not yet known, but the bird has been found in late 

 July and August along the northern coast of Siberia as far west as the 

 Taimyr Peninsula (Palmen), and it may sometimes be found on this 

 coast as a breeder. From these far western localities, it starts east 

 and south along the Alaska coast, and a few visit the Pribilof Islands 

 (specimen in United States National Museum) and the eastern
