lower edge of the upper-Canadian fir growth. Thus I have ob- 

 served a bird singing by the lakes in the Carter Notch (3,36 

 feet) on June 20, 1900, and another by Hermit Lake (3,800 feet) 

 on Mt. Washington on the same day.

221. Dendroica vigorsii (Aud.). PINE WARBLER. 



A rather common spring and fall migrant in the southern part 

 of the state, and as a summer resident not uncommon locally in 

 the Transition valleys and lowlands as far north as the White 

 Mountains. It is largely confined during the breeding season 

 to groves of pitch pine (Pimis rigida} though where these trees 

 are not to be had, it will occasionally take to the white pines 

 {Finns strobzis}. In the Connecticut valley, Mr. R. Hoffmann 

 has found this bird in small numbers as far up at least as Cor- 

 nish, during the summer. In central and southern New Hamp- 

 shire, it is not rare in the breeding season, but farther north, 

 especially in the lowlands about Ossipee, where, on a large 

 tract of dry sandy soil there is an extensive growth of pitch 

 pines, the bird is fairly common. Here, on April 21, 1900, be- 

 fore the snow was off the ground, I found a few of these War- 

 blers singing, they having evidently just arrived. Still farther 

 up the state, a few are found every year in the dry pine woods 

 at North Conway and Intervale in the Saco valley. At Inter- 

 vale three or four pairs summer annually in the white pine 

 woods at about 500 feet, there being no growth of pitch pine of 

 any size. In the fall migration I have never found the bird 

 here in any numbers, though single ones are of* occasional oc- 

 currence with the flocks of Chickadees and other small birds in 

 the woods, or even with the Chipping Sparrows and Bluebirds 

 on the open meadow lands till late September, and I have heard 

 occasional birds singing up to the 22d of that month. 



Dates: April 21 to September 25. 



221. Dendroica palmarum (Gmel.). PALM WARBLER. 



An uncommon fall migrant. Dr. A. P. Chadbourne ('84) 

 was the first to record its presence in the state on the strength 

 of a specimen shot at Shelburnc, in the Androscoggin valley, on
