This is the most abundant, generally distributed and characteristic 
species of the swallow family throughout the region along the 49th 
parallel from Pembina to the Rocky mountains. The laying season 
in this latitude is at its height during the second and third weeks of 
June. (Couwes.) Very abundant summer resident in Manitoba; at 
Brandon, Fort Ellice and Shoal lake, in 1882, they were breeding in 
very large numbers, having placed their nests under the eaves and
