Geothlypis philadelphia. Maine (Lake Umbagog). 1874. Aug. 13. Shot a young male in full fall plumage, in a little opening on a wood path. This species is more deliber- ative motions than the Maryland Yellow-throat, and I think does not jerk its tail at all. Its chirp, which I heard distinctly to-day, is almost identical with that of Siurus naevius. (Aug. 14) Shot a young bird in full fall plumage among the sgrubery in the garden. It was very tame, allowing me to approach within a few feet. In addition to the sharp chirp already described it uttered the faint lisp common to nearly all Warblers. I shot one in nearly the same place yesterday afternoon. " 20. Killed two, one an adult male in fall plumage. 1876. May 29. Shot a male in a log heap. He jerked his tail repeatedly like Geothlypis trichas and uttered a harsh whink, wheink almost precisely like that of Oporis agi- lis. June 7. Explored the sides of Upton Hill thoroughly to-day without finding a single bird of this species. " 11. One appeared behind the barn this morning and was in full song. " 20. A male sitting motionless on a tall stub at least fifty feet above the ground singing at regular intervals. " 24. Along the road between Upton and Poplar Tavern, we heard eight males singing this morning, most of them south of the Notch. In one spot two were singing with- in a few rods of each other. 1879. May 24. A female seen in brush heap. " 25. Two males singing, one in the brush-heaps behind the house the other near the Peaslee Brook. " 26. A male among fallen tree-tops behind the house clu- ded me in the most provoking manner; creeping about like a Wren among the debris. Sometimes he would appear within a few yards of me, disappearing almost instantly, and when next seen would be perhaps forty or fifty yards away. His gait was distinctly a "hop" but in other respects he resembled the Connecticut Warbler, es- pecially in flight and in attitude when perched. 59
