Young in juvenal plumage (sexes alike): Almost identical with young of Wilson's Warbler. Measurements. — Length to in.; folded wing to ; tail to ; bill .45 to .52; tarsus .65 to .71. Female slightly smaller than male. Molts. — Juvenal plumage succeeds natal down by complete postnatal molt; first winter plumage acquired by partial post juvenal molt (late June, July) involving body plumage and wing-coverts; first breeding plumage assumed after a partial molt affecting chiefly head, chin and throat, but not rest of plumage; adults have complete postnuptial molt annually (late June, July); breeding plumage probably acquired by wear. Field Marks. — Only New England warbler that is plain gray above, without white markings on wings or tail. Male: Unmistakable; well-defined necklace of black spots or streaks across yellow breast. Female: Duller than male, necklace less heavily marked and less distinct, but always discernible. Young: Resemble female, but necklace some- times barely visible, and upper plumage tinged more or less brownish, being most noticeable on head.
