144 BIRDS OF NEW ENGLAND AND EASTERN NEW YORK 



The notes of the Tree Swallow are generally sharp and 

 high, but occasionally sweet and twittering. Near a breed- 

 ing-site the male may be heard singing before dawn, either 

 from the box, or as he flies to and fro in the darkness. 



The pure white under parts distinguish this swallow 

 from both the Barn and Eave Swallows, each of which has 

 a reddish-brown chin. The Bank or Sand Swallow has a 

 brownish band across the upper breast. Young White- 

 bellied Swallows not only lack the steel-blue of the adult, 

 but have a faint brownish collar nearly across the breast ; 

 they must therefore be carefully distinguished from the 

 Bank Swallow, which has a broad dark band completely 

 across the breast. The flight of all four swallows may be 

 distinguished after much practice. Tlie White-bellied often 

 hangs in the wind with outspread wings and tail, and b*!k 

 curved like a dolphin.
