the breeding season is that of Mr. Bradford Torrey ('90, p. 251) 

 who, in company with Dr. Walter Faxon, observed one singing 

 "by the roadside in the valley," at Franconia, on June 16, 

 1889, and repeatedly in the same place on subsequent days. 

 The bird acted as if settled there, but no nest was found. The 

 following instances of its occurrence as a migrant elsewhere in 

 the state are detailed as of interest : Chocorua, where Mr. F. H. 

 Allen informs me he observed a pair on June 5, 1900, probably 

 late migrants ; Frank Bolles ('93b, p. 39) also records having 

 once observed it there in migration. Dublin, one taken Sep- 

 tember 29, 1899, and a second at the same season in 1900 by 

 Mr. G. H. Thayer ( 102) who records seeing others at Dublin 

 on several occasions in fall ; near Fitzwilliam, one obtained on 

 May 27, 1897, as I am informed by Mr. G. H. Thayer. Fran- 

 conia, one bird seen September 23d and another September 26, 

 1900, by Mr. Bradford Torrey ; Hollis, one recorded by Dr. W. 

 H. Fox ('77) as shot on May 26, 1876, by a Mr. A. F. Eaton, 

 while it was " feeding in company with two other birds of the 

 same kind, in some low oak bushes ; " Intervale, I observed a 

 single bird among some small elms in the Saco valley on Aug. 

 26, 1899, an early fall migrant doubtless. 

 Dates : May 26 to September 29. 



2O1. Vireo gilvus (Vieill.). WARBLING VIREO. 



An uncommon summer resident within the Transition .areas 

 of the state, and during the nesting season is usually confined 

 to the big elm trees of the village streets. In the White Moun- 

 tain valleys, the bird is rare so far up as Intervale, and for sev- 

 eral years I have never known more than one or two pairs to 

 summer in the big elms of the village. What I presume to be 

 the same pair of birds has for at least three successive seasons 

 lived among a group of elms near our house, and although after 

 the young were off, I have several times seen the birds in the 

 open valley at a considerable distance from their nesting site, 

 nevertheless the male is now and then to be heard singing in 

 the early morning from the same elms even into the second 

 week of September. Apparently this species is rare or gener- 

 ally absent to the north of the White Mountains, though Mr.
