CATALOGUE OF CANADIAN BIRDS. 553 



biajtfBt below Trail, B.C., in June, 1902; observed first at Penticton, 

 B.C., April 24th, 1903; they only stayed a few days when they 

 disappeared. {Spreadborough) 



Very abundant on the Athabasca River between Lesser Slave 

 River and Fort McMurray, Lat. 56° 40', first noticed June ist; not 

 rare up the Clearwater River to Methye Portage; a few birds on 

 Deep River near Isle-a-la-Crosse. (/. M. Macoun.) This species 

 is very widely distributed in the Northwest Territories and thous- 

 ands were observed fluttering at the mouths of their burrows near 

 the mouth of the Mackenzie River in Lat. 68°, on July 4th ; they 

 are equally numerous in all other localities suited for burrowing. 

 {Richardson.) North to Fort Simpson on the Mackenzie River ; 

 abundant. {Ross.) This species is to be met with inconsiderable 

 numbers during the season of nidification ; it builds its nests in 

 holes in sandy or clay banks on Anderson River. {Macfarlane.) 

 Scarce at Chilliwack; may breed in vicinity. {Brooks.) 



Along the Arctic coast, as well as the shores of Behring Sea, 

 this is an extremely rare visitant, occuring merely as a straggler, 

 during its migrations; on the river courses of the interior, however, 

 it is one of the most abundant, if not the most abundant species 

 of swallow. {Nelson.) These swallows are but occasional 

 visitors to the vicinity of St. Michael, where it was only observed 

 during the middle of the summer season. {Turner.) More plenti- 

 ful east than west of the Coast Range. {Lord) Found breeding 

 along the Thompson River at Ashcroft and more abundantly at 

 Kamloops, B.C. {Rhoads.) The bank swallow was very common 

 all along the Kowak River, Kotzebue Sound, Alaska, from the 

 delta to Hotham Inlet, eastward; on our trip up the Kowak from 

 August I2th to 19th, 1898, many colonies of the nesting burrows 

 were observed in the sandy river banks. {GrinnelL) We found a 

 small colony nesting at the northern end of Lake Tagish, July ist, 

 and a larger one on the west shore of Lake Marsh, but we were 

 entirely unprepared for the great abundance of them on Fifty- 

 mile River above Miles Canon. There, almost every bank was 

 honeycombed with their holes ; along the rest of the Yukon to 

 Circle City in Alaska, August istp after this their presence was 

 only manifested by their 'deserted holes. {Bishop.) Very abund- 

 ant af Dawson, Yukon district, Lat. 64° 15', breeding in clay 

 banks, July 19th, 1902. {Macoun.)
