This is the smallest, the most abundant, and the most widely distributed of the phalaropes; consequently it is the best known. Its breeding range is circumpolar, but extends much farther south than that of the red phalarope; it might be called sub-Arctic rather than Arctic. There seems to be only one homogeneous species around the world. It resembles the red phalarope in its habits, but is more often seen on inland waters than is that species. _Spring._--Countless thousands of these dainty little birds migrate northward off both coasts of North America in May, but very few ever come ashore except in bad weather. While cruising off the coast, 10 or more miles from land, one is likely to see them flying about in flocks, after the manner of small sandpipers, flitting about and alighting on drifting masses of seaweed or other flotsam, or swimming lightly on the smooth surface of the sea, darting hither and thither in a most erratic way, each seemingly intent on gathering its tiny bits of food. They are gentle, graceful, and charming little birds and well worth watching. There is also a heavy northward migration through the interior during May. In Saskatchewan I saw a large flock at Quill Lake on May 28, 1917; and in the Crane Lake region we recorded it as an abundant migrant; it was seen migrating, on May 29, 1905, in large flocks with sanderlings; one was seen at Hay Lake on June 15; and two were taken on June 14, 1906, at Big Stick Lake, which were in breeding condition. C. G. Harrold writes to me that it is a common and rather late migrant in Manitoba. William Rowan's notes contain several references to the enormous flocks which pass Beaverhill Lake, Alberta, in May, mostly during the last two weeks. Dr. E. W. Nelson (1887) has given us the following attractive account of the arrival of these birds in northern Alaska:
