 coinpaivs tlicsf sniuuls to the (Mackiiiii of dry i\\''\*xs or Ww strikinj^ tom-tlu'r 

 of small }n'l>l>K's. Mr. »f. A. Allen sjR'aks »>f its sow^ as bt'ini; similar to that 

 (»f tlu' ('hcstnnt-sidtHl AVarl»lt'r, which hitter bird, as is well known, has notes 

 so chjsely ivsemblinL; th(»se of the Siininier Vellow-hird that it is ditlicult t(» 

 distinijjuish (»ne from the other by their note?. Mr. T. M. Trijipe states, also, 

 that this Warbler has a very tine son'j;, reseniblinii that of the Summer Yel- 

 low-l>ird more nearly than any other. 



These Warblers arrive in Massachusetts about Jio tii-st of May, and remain 

 about three weeks, when the larger ]>(ution nun<' farther north. 



More reientlv Mr. I'aine writes nie that the Nashville Warbler has of 

 late years become a eonnnon bird in certain L»cjilities in Central Vermont. 

 They come and keep eoni])any with the Canada Warbler, but are more rest- 

 less than that species at the time of their first a]H)ear.ince. They always 

 in the breed in jj^-season take up their abode in thickets, where there art; also 

 tall trees. Mr. Paine adds that their son^ consists of repetiti(»ns of single 

 notes, the last terminatiui*' somewhat abniptlv. Their son*' ceases bv the 

 loth of June. After their young are ready to tly, they disperse about the 

 woods and tields, and are then not readily discovered.
