Occasionally in August and September of past years large flocks of small shore birds have been seen a long way offshore in the sand-dune region of southern Lake Michigan circling and wheeling, flashing alternately snow-white breasts and darker backs. Long-range examination with binoculars showed rather prominent whitish wing bars, but the identity of the birds was never satisfactorily determined until the afternoon of August 28, 1921, when the writer was camping at the mouth of the above-mentioned Bar Creek, in Sheboygan County, Wis. About 2 o'clock in the afternoon a light fog drifted in, and soon after large numbers of small shore birds, similar in actions and appearance to those mentioned, were sighted executing extraordinary maneuvers close to the surface of the water about 500 yards out. They circled and recircled, turned and twisted, some of the flocks finally alighting in some smooth streaks in the water inshore of a long line of net stakes that extended about a mile out. Fully 500 of the birds, now recognized as phalaropes, were in sight. One specimen, a female in fall plumage, was finally secured by tying the shotgun onto driftwood pieces and swimming out among them. They were in no way disturbed at my presence until a shot was fired, and I fully satisfied myself that the bulk of the flock were of the same species as the one secured, northern phalaropes.
J. A. Munro tells me that these birds are irregular fall migrants at Okanagan Landing, British Columbia, from July 28 to September 18. Along the California coast the fall migration is heavy and prolonged from the latter part of July until late October or early November, the bulk of the flight passing during August and September. Grinnell, Bryant, and Storer (1918) say:
Heavy winds on the ocean sometimes prove disastrous to the migrating hosts of northern phalaropes. Chapman records finding many bodies of this species in the tide pools of the Farallon Islands. A heavy northwest wind had been blowing along the coast for the previous two weeks, and many of the birds had resorted to inland pools of water. The emaciated condition of the birds at the Farallones was probably due to their inability to procure food while on the open ocean in migration. Forbush records numbers of these birds as being killed on the Atlantic coast by dashing against lighthouses at night. In the Cape Region of Lower California, Brewster found that "most of the birds examined had lost one or more toes, and two or three an entire foot, and part of the tarsus also, while others showed gaping wounds on the breast. These mutilations were probably caused by the bites of fishes." Emerson records finding several of these birds killed by flying against the telephone wires strung across the salt ponds on the marshes west of Hayward, and says that very many of this and other species of birds are killed in this manner.
Winter.—Practically nothing is known about the winter home of this species in the Western Hemisphere. It is evidently south of the borders of the United States and probably south of the Equator on the open ocean. The few straggling winter records for California and South America give but a scant clue to the winter resorts of the vast numbers that pass us on migrations.
DISTRIBUTION
Range.—Distributed over both Old and New Worlds.
Breeding range.—Arctic regions of both hemispheres. In Europe and Asia the breeding range of the northern phalarope extends from Iceland, Spitsbergen, and Scandinavia, across northern Russia and Siberia to Bering Sea. South to Sakhalin Island, southern Russia (Orenburg), and the Outer Hebrides, Shetland, and Orkney Islands.
In North America the breeding range extends north to Alaska (Near Islands, St. Paul Island, Nelson Island, Pastolik, St. Michael, probably Golofin Bay, the Kowak Valley, Cape Blossom, Point Hope, Point Barrow, and the Gens de Large Mountains); Mackenzie (Franklin Bay); Keewatin (Cape Eskimo); probably Baffin Island (Cumberland Sound); and Greenland (North Star Bay, Upernavik and Jacob's Bight). East to Greenland (Disko Island); Labrador (Nain and Hopedale); and western Quebec (Fort George and Rupert House). South to western Quebec (Rupert House); northern Manitoba (York Factory and Fort Churchill); Mackenzie (Artillery Lake and Fort Rae); and Alaska (Nushagak and Kiska Island). West to Alaska (Kiska and Near Islands).
Winter range.—The winter range of the European and Asiatic birds appears to extend south to southern Japan, the north coast of New Guinea, Ceram, the coast of Beluchistan, the east coast of Arabia, and probably points in the northern part of the Indian Ocean.
The winter range of North American breeding birds of this species is more or less imperfectly known, and they are believed to winter largely at sea. It has been reported as wintering in southern California; it has been taken or observed in Costa Rica (Desamparados) and Peru (Tumbez); there is a specimen in the museum at Buenos Aires, Argentina, that was taken in Patagonia.
