Geothlypis philadelphia. Maine (Lake Umbagog). copy① 1871. May 30- June 10. Rather common. Haunting wood-edges and small clearings and grown up bushes. On the Stage road be- tween Upton and Poplar Tavern we heard no less than so- ven males singing in the course of a single morning, they almost invariably sing from the protecting branch of some dead stub. Twenty or thirty feet above the ground. The ordinary note is precisely like that of the Mary- land Yellow-throat. In addition they have a shrill pot- lent chirp inclined to be characteristic. copy② 1872. June 3- 14. Common in a rather limited locality on the side of Upton Hill. They haunted brush fences, old log heaps, and thickets of raspberry bushes, rarely far from the woods and usually along their edges. Sometimes a pair would be found in some small but sunny opening well within the forest, but never actually under its gloomy shade. In their habits and motions they resemble G. trichas but are more timid and retiring as well as very much harder to shoot, for they plunge into their favor- ite thickets on the slightest alarm. Several males were shot in the very tops of the tallest beeches and birches along the wood edges at least seventy or eighty feet above the ground. In these situations they show- ed much activity, chasing insects among the branches and frequently singing. Although they sang from elevated and exposed perches, much oftener than G. trichas this practice seemed rather the exception than the rule the present season, for usually the song would be heard on or near the ground in the long heaps. It is a short but very sweet, rich warble sounding like wheos-wheos- wheos-wheos, tu-tu-tu-tuo. It varied somewhat with dif- ferent singers, and was sometimes shortened to wheos- wheos-tuo-tuo. Occasionally they sang on wing soaring high in air like S. aurocapillus, prefixing a few extra notes to the ordinary ones, and at the end, closing their wings and dropping to the ground as if shot. 1874. Aug. 11. Shot a young bird in full fall plumage. Also shot two young just from the nest which I take to be of this species; they are darker about the head than the Mary- land Yellow-throat, and rather larger. One of them, however, uttered the characteristic tshay of the Mary- land and an adult female of that species was chirping anxiously near the spot. 58
