Contopus virens. Descriptions of First Plumage of Certain North Am. Bbs. Wm. Brewster. 85. Contopus virens. First plumage: male. Above olive, with a brownish cast, the feathers of the crown and interscapular region with a faint edging of pale fulvous, those upon the nape having a much broader one of dull ash, producing a well-defined band or collar. Wing-bands light reddish-brown. Beneath, with sides of throat, breast, and body, light olivaceous-ash ; rest of under parts pale sulphur-yellow. From a specimen in my collection taken at Upton, Me., August 8, 1874. The young in autumnal plumage differ from adults in having the wing-bands pale fulvous, the under parts of a slightly deeper yellow. Bull. N. O. C, 3, Oct., 1878, p. 177.
