674 GEOLOGICAL SURVEY OF CANADA. 
rare migrant in eastern Manitoba. Near Long river, Man., I saw a 
black-capped warbler on May 21st, 1882, my only record, though 
others claim it is a summer resident. (E. T. Seton.) Found at 
Grand rapids and Chemawawin on the Saskatchewan. (Nutting.) 
One pair seen at Fort McMurray, lat. 56° 40’; common on the Methye 
portage; common between Methye portage and Isle 4 la Crosse. 
(J. M. Macoun.) Tolerably common in migration at Aweme, Man., 
may breed. (Criddle.) An abundant migrant in all the wooded 
districts of Manitoba breeding in suitable locations; also observed 
in 1906 at Wainwright and Battle river, Alta. (Atkinson.) Three 
individuals were seen on May 15th, 1894, at Medicine Hat, Sask., 
and later a few more; first seen at Edmonton, Alta., on May 2oth, 
1897, a few pairs remained to breed; quite common and: breeding 
at Banff, Rocky mountains, in June, 1891; abundant at Revelstoke, 
on the Columbia river, from May 15th, 1890, nested in the woods in 
large numbers; observed one individual on the International bound- 
ary near Trailin May, 1902. (Spreadborough.) 
North to Lapierre House on the Mackenzie river; very rare. 
(Ross.) Preble collected one at Last woods, Artillery lake, August 
5th, 1907. (E. T. Seton.) This is one of the commonest brush- 
frequenting species in the north and extends its breeding range to 
the shores of the Arctic ocean where it is found breeding about 
Kotzebue sound as well as along the entire coast of Norton sound, 
wherever shelter is afforded. (Nelson.) The series of Wilson‘s 
warbler taken in eastern and western British Columbia compared 
among themselves and with specimens from the Atlantic states are 
devoid of any differences which would justify their separation. 
(Rhoads.) A single specimen of this species was captured by a 
native in the bushes which skirted a lake about a mile distant from 
the redoubt at St. Michael; it is not a common.bird in that vicinity, 
occurring only in the fall migrations; other specimens were obtained 
from Fort Yukon and Nulato, where it is not rare. (Turner.) 
Osgood took an adult female near the Chandindu river, Aug. 4th, 
1899, and I a young female near Charlie Village, Aug. 11th, and a 
young male 25 miles above Circle City, Alaska, August 20th. These 
birds, while not typical pusilla, are, like those of the lower Yukon, 
nearer it than pileolata. (Bishop.) 
BREEDING NoTes.—On June 14th, 1893, I found a nest and four 
eggs of this species and secured the parent. The nest was built
