Only observed at Pembina on the 49th parallel where it was 

 breeding in small numbers about the fort. (Coues.) Common 

 summer resident of wooded parts of Manitoba; on July 17th went 

 to White Horse hill; found a large colony of white-breasted swal- 

 lows nesting in old woodpecker's holes, with which the timber is 

 riddled ; this is the largest colony I have seen ; it numbers perhaps 

 20 pairs; nearly all of these settlements that I have noted have 

 been close to a sheet of water. (E. T. Seton.) Fairly common at 

 Aweme, Man. (Criddle.) One of the most abundant breeding 

 species in Manitoba, and the west. (Atkinson.) First seen at 

 Indian Head, April 8th, 1892; they became common by May 19th, 

 but a few remained to breed as they were seen as late as June 24th ; 

 only two specimens observed at Crane lake in i8'94 ^^d none at 

 Medicine Hat; a few specimens were observed at Waterton lake, 

 close to Chief mountain in August, 1895; observed from the mouth 

 of Lesser Slave river to Peace River Landing, lat. 56° 15', June, 

 1903; first seen at Edmonton, Alta., April 30th, 1897, breeding in 

 trees late in May, found a nest in a hole in a balsam poplar stub

 ing in great numbers throughout northern Saskatchewan. (Cotiheaux.) 

 While on a moose hunt, about twenty miles above Chemawa- 

 win, I saw apparently thousands of these birds on a few 

 dead trees standing out in the marsh. Some of those trees 

 were so crowded by the perching swallows that there seemed 

 literally to be no more room. (Nutting.) A few specimens 

 were seen between Athabaska Landing and Lesser Slave river; 

 a few individuals at north end of Methye portage ; about half 

 a dozen birds on Isle a la Crosse lake. (/. M. Macoun.) 

 This neat and handsome bird frequents the wooded districts up
