24 Audubon's avaeblee, 



found all winter in the towns of Leominster, Arlington 

 and Quinc}-, Massachusetts; from this point probably south- 

 ward throughout Cape Cod, and along the coast north- 

 ward at intervals as far as Scarboro, Maine. It occurs reg- 

 ularly from Southern Connecticut southward as far as 

 Florida, on the Bahamas, and other West Indies, through 

 Mexico to Panama. 



It migrates southward late, some occurring in Central 

 Maine until about the middle of October. 



Song. While migrating, the Yellow-rumps give a 

 rather soft chirp, and when alarmed a louder note. 

 The song is a rather low and somewhat varied war- 

 ble that is quite pleasing. It is usually rather short, 

 consisting of four or five notes. In autumn the young 

 occasionally give a sweet, low practicing song, similar 

 to that uttered by other young birds.
