Dendroica blackburniae. Descriptions of First Plumage of Certain North Am. Bbs. Wm. Brewster. 29. Dendrœca blackburniæ. First plumage: male and female. Remiges, rectrices, etc., as in autumnal adult; rest of upper parts uniform dark brown, each feather on the back edged with light buff; the white scapular stripe poorly defined. Head markings precisely similar in pattern to the adults', but with the orange everywhere replaced by white, slightly tinged with buff on posterior half of superciliary line. Throat and entire under parts, in the male, clear white, tinged with pale yellow, each feather (excepting on throat) spotted terminally with black. From two specimens in my collection taken at Upton, Me., August 5 and 6, 1874. One of these, the male, has a few orange feathers on the throat, indicating the coming fall plumage. "Young in autumn. Above similar to the adult female in fall plumage, but more olivaceous; all the markings less distinct. Superciliary stripe and entire lower parts, except the crissum, pale yellowish-buff, hardly brighter on the jugulum. Sides very faintly streaked with grayish. In my collection (No. 1003), Mt. Carmel, Ill., August 15, 1870."—R. R. Bull. N. O. C. 3, April, 1878. p. 58.
