In fresh juvenal plumage, in July, the feathers of the crown, back, scapulars, tertials, and all wing coverts are dusky or nearly black, broadly edged with "light pinkish cinnamon" or "cinnamon buff," broadest and brightest on the scapulars; the under parts are white, but the throat, sides of the breast and flanks are washed with "pinkish buff," and the last two are mottled with dusky; the central tail feathers are broadly edged with "pinkish buff," bordered inwardly with a broad dusky band, surrounding a white area, with a dusky central streak invading it; the other tail feathers are similarly marked, but less completely patterned. This plumage is worn for only a short time, as the body plumage and tail are molted during the last half of July and in August. By September young birds are in first winter plumage, which is like that of the adult, except that the entire juvenal wing is retained with the buff edgings faded out to white. The sexes are alike in juvenal and all winter plumages. A partial prenuptial molt in the spring, involving the body plumage and most, if not all, of the wing coverts and scapulars, makes the young bird practically adult. Adults have a partial prenuptial molt in April and May, involving the tail, the wing coverts and all the body plumage, which produces the well-known brilliant plumage of the female and the duller plumage of the male. The complete postnuptial molt in summer produces the gray winter plumage in both sexes, in which the crown, back, and scapulars are "light drab" or "drab-gray," with narrow white edgings, and the upper tail coverts, as well as the under parts, are white. The sexes can be recognized in adult winter plumage by size only. _Food._--The other two species of phalaropes feed mainly on the water, but the Wilson phalarope is more of a shore bird and obtains most of its food while walking about on muddy shores or wading in shallow water. It does, however, adopt the whirling tactics of the others occasionally, concerning which Mr. Dawson (1923) says:
