Parus hudsonicus. Descriptions of First Plumage of Cer- tain North Am. Bbs. Wm. Brewster. 12. Parus hudsonicus. First plumage: female. Above olivaceous-drab, becoming much darker and more dusky on crown. Sides and anal region very pale brownish- rusty. Otherwise like adult. From a specimen in my collection taken at Upton, Me., August 25, 1873. This bird is, strictly speaking, in a transitional stage, having already acquired many feathers of its fall dress. It differs sufficiently, however, from the perfected condition of the autum- nal plumage to merit description under the above heading. Bull. N. O. C. 3. Jan., 1878. p. 20.
