summer, and the Red-eyed is numerous and voluble as usuaL 

 The most attractive of the family is the Blue-headed or Solitary. 

 Its sweet song, in form like the Yellow-throated but in a voice 

 of its own, may be heard almost anywhere in mixed or hard- 

 wood forest. The nest is suspended below the fork of a small 

 branch a few feet from the ground. Hemlock and spruce trees 

 appear to be preferred. 



The Warblers of Pocono have received perhaps more than 

 their share of attention. Fourteen or more species nest there, 

 affording an attractive field for study. 



The Black and White Warbler is fairly numerous, revealing 

 its presence among the trees by its song which differs from that 

 of most of the warblers, in that the notes are so nearly all 

 alike. A variation is given occasionally, however, which makes 

 one think a moment before naming the author. The tone is 

 thin and shrill. The nest is placed on the ground, often con- 

 cealed under a stick or other protection. 



The Golden-winged Warbler has been reported a few times, 

 and the Brewster's once during migration. Their status as 

 breeders is not known. 



The Nashville Warbler is one of the surprises of the region. 

 Almost as numerous as on the slopes of the White Mountains, 

 one meets with a singing male every mile or so in suitable 

 country. Were it not for the song, the bird might remain un- 

 detected indefinitely, for one harder to see is scarcely to be 

 found outside of the rail family. The bird has no striking 

 color marks, and keeps itself closely hidden among the leaves. 

 When one does catch a glimpse of the little fellow, he is very 

 likely to fly away for several hundred yards, so that the entire 

 search must be begun again. The absence of black spots, the 

 bluish color of the sides of the face and the yellow under parts, 

 are the available field-marks. The spot on the crown is prac- 

 tically never visible. The song begins like that of the Black 

 and White Warbler, suddenly changes in the middle and fin- 

 ishes in the tune of the Worm-eating Warbler or Chipping 

 Sparrow. I have noticed no variation in several thousand 

 renderings. Two or three nests have been found. The writer 

 was not fortunate enough to see any of these, so can give no
