AMERICAN WARBLERS. 95 



and second part of the song is quite niarked. This is the us- 

 ual summer song-. Earh'er in the spring, just after its arrival 

 from the south it gives a more contiiuious lay, one which is not 

 as energetically uttered. I find some authors are inclined to 

 think the song of the Nashville like that of the Chestnut-sided, 

 but I do not find the usual S3ngs uttered by the respect- 

 ive species at all alike; the truth is, however, that the Chest- 

 nut-sided gives a song, oftener late in June thaa at any other 

 time (cccasionally this song is given in May), that is so near- 

 ly like that oi^ the Nashville Warbler that I have frequently 

 been deceived by it. See pages 67-8 for remarks regarding 

 this song of the Chestnut-sided. The Blackand White Creep- 

 er also has a song quite like that of the Nashville Warbler. 

 The alarm note oi'the Nashville is a sharp chirp and some- 

 times they utter a kind of clicking sound when they are dis- 

 turbed. 



MiGRATioM AND Breedixg Range. The Nashville War- 

 bler breeds all over New Eno-land, but it is less common in 

 the southern portion than in the northern. It breeds west as 

 far as the Mississippi and north to Grand Menan and the 

 Great Slave Lake district. It has been taken twice in Green- 

 land, but many years ago. It winters in eastern Mexico and 

 Guatemala, and on the migrations thus passes through the 

 middle districts of the United States more commonly. A 

 single specimen was taken at Jacksonville, Florida, on March 

 22, 1869. I found one in Williamsport, Pennsylvania, on May 

 12, 1876, and a few at Watsontown on September 22,1875. 

 The majority do not arrive in Massachusetts until about May 

 8. Most all leave early in September.
