CATALOGUE OF CANADIAN BIRDS. 643 



A common species eastward, but only observed on the 49th 

 parallel in the Rocky Mountains near Chief Mountain. {Coues.) 

 A 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. (Thompson-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 a la Crosse. (/. M. Macoun,) A tolerably common summer 

 resident at Avenue, Manitoba; arrives about May i8th and leaves 

 about the middle of September. (Norman Criddle^ Three 

 individuals were seen on May 15th, 1894, at Medicine Hat, 

 Assa., and later a few more; first seen at Edmonton, Alta., on 

 May 29th, 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 Boundary near Trail in May, 1902. {Spreadborough.) 



North to Lapierre's House on the Mackenzie River; very rare. 

 {Ross.) 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 ayoung female nearCharlie Village, Aug. nth, and a young 

 male 25 miles above Circle City, Alaska, August 20th. These 

 birds, while not typical pusilla, are, like those of the lovver 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 

 on the ground in a willow swamp in a clump of herbage on the
