I believe that this species has been pretty generally overlooked by rnost ob- 

 servers ami mistaken for the Bank Swallow, and that it really is eoiuiiiouer than 

 the Bank Swallow and fully as widely distribut(>d in the state. It oeeurs at 

 somewhat higher elevalions, nesting in banks, in old burrows of tlie Kingrisher. 

 oi in burrows of its own. 1 have founil a few ]>airs nesting with a colony of 

 i^auk Swallows, liul tie' Kough-winged Swallow is uioi-c liable to nesi sinuly or 

 in colonies of only a few pairs. 1 have never opened a nest and know of no ilate 

 for eggs in the state. Young of the year havt been noted and secur( d at Flal- 

 head Lake in August, 1897, and on July 2:^, 1914, and in Gallatin Coiaily. August 

 22, 188S.
