The Eough-winged Swallow is a summer resident throughout the 

 State, frequenting principally such places as the Bank Swallow loves. 

 It is, however, not so numerous as that well-known species. In the 

 northern part of the State it is rare, and in many localities wanting. 

 Because of the general lack of metallic lustre to the upper plumage, 

 they are not usually distinguished. But this species may be known 

 by its grayish throat and breast. While they breed together, excavat- 

 ing burrows in the same bank, I have observed that the single holes 

 away from the colony contained nests of the present species. They 

 also nest in open joints in masonry, the foundations of buildings, 

 mortises, holes in the sides of buildings and even within buildings, 

 where the nest is placed on a beam. Dr. Rufiis Haymond was one of 

 the first to call attention to the Rough-winged Swallow beginning to 

 change its nesting habits (Field and Forest, Vol. I., 1876, p. 88; also, 



E. Coues, Bulletin Nutt. Orn. Club, Vol. I., 1876, p. 96, and American 

 Naturalist, Vol. X., 1876, pp. 492, 493). The Bank Swallow has never 

 attempted to find a better nesting site than a sandy bank. 



I have found them mating as early as April 25, 1881. Prof. B. W. 

 Evermann found nests nearly completed at Gosport, May 8, 1886. Dr. 



F. W. Langdon says : "Of a dozen or more nests of this species, taken 

 at Madisonville, 0., May 20-21, 1879, those from inland situations 

 (along creeks and bridges) were complete in number (5 to 7) and well
