Upton, Maine. 7 1871 28 Sylvia nisus. Occurs sparingly in the clearing where it breeds in the Martin cups and hollow "stubs" 29 Regulus satrapa. Affects the cedar swamps and fir thickets when it is quite common, and breed. Took a female john G that had evidently been incubating some time but was unable to dislodge the nest. The males had a simple warbling song slightly resembling that of D. Blackburnia 30 Pandas Americana. Frequent; affects the tops of the beech and birch trees. 31 Catharys trichas. Found sparingly in the clearings. 32 Catharys Philadelphia. Rather common its favorite resorts are the edges of the woods and small clusings grown up to bushes. On the stage road down we heard no less than four males singing in the course of a ride of as many miles. The male, unlike G. trichas, which it otherwise greatly resembles in habits, always sings from the projecting branch of some dead "stub" at the height of about twenty or thirty feet; out of a dozen or more observed, there were no exceptions to this rule: the song is extremely beautiful; resembling somewhat that of S. woodhousei, which however it much surpasses, it commences with two high notes and ends in a most exquisite warble with a falling inflection to the end, altogether overflowing that of any bird in the region it inhabits. It ordinary ship is pretty like that of G. trichas but it has also a shrill jubilant cheering note never heard from that bird.
