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 fia records for North America seem to be during the fall migra- 
tion, at. which period—crossing to America on the way to its winter 
ious 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 
(Fannin) , 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 strawclors. 
Pectoral Sandpiper. Pisobia oihcuat (Vieitl ). 
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 (Sharpe). Though confined i in summer 
to the seacoast, yet in its migrations it has been noted i 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
