Picoides arcticus. Descriptions of First Plumage of Certain North Am. Bbs. Wm. Brewster. 95. Picoides arcticus. First plumage: male. Similar to the adult, but with the yellow crown-patch rather more restricted; the black of the upper parts duller; the white beneath tinged with brownish, and the bars upon the sides dusky instead of black. A few feathers upon the lower interscapular region are spotted with white. From a specimen in my collection shot at Upton, Me., July 31, 1874. Unfortunately no females in strictly first plumage are available for comparison. A moulting specimen, however, which has acquired most of the second or autumnal plumage (Upton, Me., August 10, 1874), shows a patch of thickly sprinkled yellow feathers upon the crown, while another, taken as late as September 5, still retains several similar feathers. There can be little doubt but that among a good series of young females in first plumage many would be found to occur with yellow crown-patches quite conspicuously developed. All among a large number of adult females examined have the crown entirely plain. Bull. N.O.C. 3, Oct., 1878. p. 180.
