THE BANK SWALLOW 



Range: North and South America. Breeds from the tree- 

 regions of Alaska and Canada to southern California, 

 Arizona, Texas, Louisiana, and Virginia. It mi- 

 grates through Mexico and Central America and 

 probably winters in northern South America to 

 Brazil and Peru. 



THE ROUGH-WINGED SWALLOW resembles the bank 

 swallow so closely that it is difficult to distinguish 

 tliem, unless one can see the darker breast and throat of 

 the rough-wing and the absence of a dark band across the 

 breast. Upon careful examination of the latter species, 

 each long outer wing-feather is discovered to have a rough 

 saw-tooth edge. 



The habits of the birds are similar, though the rough- 

 wings, like phoebes, nest not only in banks, but against 

 stone walls and stone bridges. They have a more re- 

 stricted range than barn swallows. They breed from 

 southern Canada to northern Florida and southern Cali- 

 fornia, and winter in Mexico and Central America.
