WITH BROWN PREDOMINATING 259 



lustreless sooty-gray plumage and entire absence of 

 metallic coloring. 



In habits the two are very much alike, nesting in 

 banks and congregating in flocks for migration. The 

 Rough-winged are, however, found in small colonies, — 

 seldom more than two or three pairs in a bank, — and 

 are more apt to choose a gravelly soil than are the bank 

 swallow^s. They are somewhat less timid also, and 

 sometimes make their nests about buildings. The one 

 essential seems to be running water, and crevices in the 

 abutments of bridges are often filled with their nests. 

 The hooked edge of the wings, which has given them 

 their name, seems to be slightly less prominent in the 

 present species than in specimens collected fifty years 

 ago, and it is possible that this characteristic will become 

 modified as their environment changes.
