that these flocks of July 10, already several hundred miles south of 
the breeding grounds, must consist either of barren birds or of those 
that had suffered loss of their eggs. In southern British Columbia, 
the average date of arrival is August 11, earliest August 6, 1888 
(Brooks) ; near Monterey, Calif., August 25, 1897 (Mailliard) ; southern 
Saskatchewan, July 17, 1906 (Bishop); southern Manitoba, July 23, 
1881 (Macoun); Lincoln, Nebr., August 9, 1900 (Wolcott); southern 
Ontario, July 28, 1891 (Nash); Locust Grove, N. Y., August 18, 1885 
(Henshaw); Baston Harbor, August 27, 1870 (Henshaw) ; Montauk, 
N. Y., August 14, 1907 (Braislin). In September it reaches its 
winter home in southaris South America. 
The last were seen at Point Barrow, Alaska, August 12, 1883 (Mur- 
doch), and September 4, 1897 (Stone); southern British Columbia, 
September 15, 1903 (Brooks); Fort Lyon, Colo., September 28, 1885 
(Thorne); Lincoln, Nebr., November 3, 1900 (Wolcott); southern

1887 (Woodruff) ; Galapagos Islands, October 6, 1897 (Rothschild and 
Hartert). 
Least Sandpiper. Pisobia minutilla (Vieill.). 
Breeding range.—The least sandpiper nests in the far north to 
northern Ungava (Turner); at Cambridge Bay in southern Franklin 
(Collinson); the coast of Mackenzie (MacFarlane); and Kotzebue 
Sound, Alaska (Grinnell). _ Unlike most of:the Arctic breeding shore- 
birds, it breeds also quite far south to Sable Island (Oates); Magdalen 
Islands (Job); northeastern Quebec (Audubon); upper Hamilton 
River, Ungava (Low); Fort Churchill, Keewatin (Preble); Lake 
Marsh; southern Yukon (Bishop); and in Alaska south to Yakutat 
Bay (Merriam). The western limit of the. peeeding range in Alaska 
is not yet definitely settled. 
Winter range.—The species is recorded without exact locality from 
Chile (Salvin), has been taken at several places in Peru (Tacza- 
nowski), and ranges south in Brazil.to Pernambuco (Allen). Thence 
it is known throughout northern South America, Central America, 
Mexico, and the West Indies, the coast of Georgia (Helme), rarely in 
winter to North Carolina (Bishop), southern Texas (Merrill), southern 
Arizona (specimen in United States National Museum), and southern 
California, north at least to Owen Lake (Fisher) and Humboldt Bay 
(Townsend). 
Migration range.—Beyond the known breeding range, the least 
sandpiper is found in fall on the west coast of Greenland north to God- 
haven, latitude 69° (Walker); at Plover Bay, Siberia (Bean). It 
occurs during most if not all the summer on the Alaska Peninsula 
(Osgood) and on the Aleutian Islands west to Unalaska (specimen 
in United States National Museum). 
Spring migration.—Though wintering so far north, this species is 
one of the later shorebirds to migrate. Most of the migrants cross
