slightly over 3,000 feet. They avoid the forest, however, and 

 are more frequent in low growth along open spaces. 

 Dates : May 19 to September 13. 



229. Geothlypis trichas brachidactyla (Swains.). 

 Northern Yellow-throat. 



A common summer resident of swampy, weed-grown localities 

 in the Transition and sub-Canadian areas, following the valleys 

 up to about 2,000 feet in the White Mountains. 



Dates : May 8 to October 7. 



Note: Icteria virens Linn.). Yellow-breasted Chat. 



According to T. M. Brewer ('78, p. 303) a nest and four eggs of this 

 bird were taken in the summer of 1877 at North Conway, by his "young 

 friend, C. A. Hawes." It seems unlikely, however, that so southern a 

 bird should breed i.hus far to the northward, and until a well authenti- 

 cated specimen can be shown from the state it should not be given a 

 place among the birds of New Hampshire. Careful search on our ex- 

 treme southeastern borders might nevertheless establish its occasional 

 presence there. 



230. Wilsonia pusilla ( Wils.). Wilson's Warbler. 



An uncommon spring and fall migrant and a rare summer 

 resident in the upper Canadian faunal area. Mr. F. B. Spauld- 

 ing ('94) has recorded finding a nest with four eggs on June 5, 

 1894, near Lancaster. The female bird, he states, was captured 

 on the nest. Dr. Walter Faxon informs me, also, that he ob- 

 served a single bird below Warren Village on June 4, 1895, 

 perhaps a late migrant. I have never found the bird among 

 the White Mountains in the breeding season, and although Mr. 

 C. J. Maynard ('72) quotes Mr. William Brewster as author- 

 ity for its presence during summer at Gorham, it appears that 

 the birds in question were probably early fall migrants. At In- 

 tervale, the first fall migrants appear in the valley about the mid- 

 dle of August, my earliest date being on the 15th of that month. 

 Single birds are usually found, or more rarely two may be ob- 

 served accompanying a flock of other Warblers and Chickadees 

 in a damp, bushy locality. Dr. Walter Faxon has observed 

 the bird at Warren so late as October 3d . 



Dates : May 13 to October 3.
