On dry side hills, particularly those with growths of birches 

 and a few pines, we may, at the proper season, nearly always 

 hear the homely but distinctive ditty of NASHVILLE 

 WARBLERS, one of the most diminutive species. Their 

 songs are fairly constant in character, a series of about six 

 consecutive "chips" followed by a twitter or trill about two 

 notes lower in pitch, like "chip, chip, chip, chip, chip, r-r-r- 

 r-r-r-r. " When singing, the male is usually perched in the 

 summit of small trees. He is rather shy and usually keeps 

 a safe distance ahead of you if you try to follow him up. 

 The female is so obscurely colored and so small that she is 

 seldom seen unless you startle her from her nest, which is a 

 small structure of grass and pine needles sunk in the grass or 

 moss and usually concealed by weeds, a bush, or rock. The 

 centre of abundance of Nashvihes appears to be in New 

 England, but they occur in all our Northern States and in 

 southern Canada. In migration they go diagonally across 

 to Mexico and do not occur in any of the Southeastern States.
