     reeds with great regularity every night, and early in the morning fly 
     
     out. over the country to feed. Their flight in the evening is com- 
     
     paratively low, at an average height of thir ' to forty feet. They sail 
     
     about in circles more than other Swallows, ind many pause to rest 
     
     on telegraph wires, where their pure white breasts easily distinguish 
     
     them from the Swallows which may be associated with them. In the 
     
     morning,r their flight is much higher and more direct. They migrate 
     
     by day. leaving their roosting ground in flocks, which sometimes con- 
     
     tain myriads, and, after attaining a great height, pursue their journey 
     
     to the south. When mig 'ating along the coast they sometimes collect 
     
     in large numbers in bayberry bushes (JIg/rz'ca cerifem) and feed on 
     
     their t‘ruit.

     This is a locally distributed species breeding in colonies only where 
     
     sand banks offer it a favorable nesting site. Probably for the reason 
     
     that such banks are more frequently found bordering streams than 
     
     inland, the birds are more numerous in the vicinity of water. 
     
    

    
     Bank Swallows may be readily known from other Swallows. except- 
     
     ing the Rough-winged, by their nesting habits, small size, and absence 
     
     of metallic coloring. 
     
    

    
     From the Rough-wing they differ in having,r the under parts white, 
     
     with a conspicuous band across the breast, and in their somewhat 
     
     quicker movements.
