m 2 CATALOGUE OF CANADIAN BIRDS. 553 
bia just 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. (J. W. 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 in considerable 
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. (Bvooks.) 
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. (NVelson.) These swallows are but occasional 
visitors to the vicinity of St. Michael, where it was only observed 
during the middle of the summer season. (Zurner.) More plenti- 
ful east than west of the Coast Range. (ZLord.) 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 12th to 19th, 1898, many colonies of the nesting burrows 
were observed in the sandy river banks. (Gvinnell.) 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 Cafion. There, almost every bank was 
honeycombed with their holes ; along the rest of the Yukon to 
Circle City in Alaska, August Ist; after this their presence was 
only manifested by their deserted holes. (Beshop.) Very abund- 
ant at. Dawson, Yukon district, Lat. 64°-15', breeding in clay 
banks, July 19th, 1902. (AMWacoun.)
