_Eggs._--Mr. Harlow tells me that the Cape May warbler lays from 4 to 9 eggs to a set. The larger numbers must be very rare, but 6 or 7 seem to be the commonest numbers among my records, and sets of 4 seem to be uncommon. The eggs vary in shape from ovate to short ovate and are almost lusterless. They are creamy white, richly spotted and blotched with shades of reddish brown, such as "auburn," "chestnut," "sayal brown," "bay," or "snuff brown," with an occasional scrawl of black. The undermarkings are of "fawn," "light brownish drab," "brownish drab," or "light mouse gray." The markings are more concentrated at the large end. The measurements of 50 eggs average 16.8 by 12.5 millimeters; the eggs showing the four extremes measure =18.4= by 12.3, 18.0 by =14.0=, =15.0= by 12.0, and 16.0 by =11.5= millimeters (Harris). _Plumages._--Dr. Dwight (1900) describes the juvenal plumage, in which the sexes are alike, as "above, dark hair-brown, olive tinged on the back. Wings and tail black, edged chiefly with dull brownish olive-green, the coverts with drab and tipped with buffy white. The two outer rectrices with subterminal white spots. Below, including sides of head, mouse-gray with dusky mottling or streaking on the breast and sides; the abdomen and crissum dingy white faintly tinged with primrose-yellow." The partial postjuvenal molt, beginning early in July, involves the contour plumage and the wing coverts, but not the rest of the wings or the tail. This produces the first winter plumage, in which the sexes begin to differentiate. Dr. Dwight describes the first winter male as "above, dull olive-green, each feather centrally clove-brown veiled with olive-gray edgings; the rump canary-yellow, the feathers basally black. Below, including sides of neck, superciliary lines and spot under eye, canary-yellow, palest on abdomen and crissum, narrowly streaked on sides of chin, on the throat, breast and sides with black which is veiled by grayish edgings; auriculars mouse-gray." The young female, he says, is "duller and browner above, and generally without yellow below, being dull white with gray streaking." The first nuptial plumage is acquired by a partial prenuptial molt beginning in late winter, "which involves much of the body plumage but not the wings nor the tail. The black crown, the streaks on the back, the chestnut ear-patches and the streaked yellow of the throat and breast are acquired," in the male. The female in first nuptial plumage "shows a little yellow assumed by a limited prenuptial moult." Both sexes are now in nearly fully adult plumage, except for the worn juvenal wings and tail.
