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:
