this point was about to be concluded, as female specimens pre- 

 ponderated; the species was not observed further west on the 49th 

 parallel. {Coues.) Not an uncommon summer resident in the 

 wooded parts of Manitoba, apparently breeding on Duck Moun- 

 tain. {Thompson-Seton.) 



This is a common migrant at Indian Head, Assa., and very 

 likely breeds ; first seen May 31st, and soon became common in 

 willow thickets where it remained to June 15th, when all disap- 

 peared ; first seen at Medicine Hat, Assa., May i8th, 1894; others 

 were seen afterwards, but they were never numerous; a few seen 

 on Old Wives' Creek, Assa., late in May, 1895; a commqn breed- 

 ing species at Banff, Rocky Mountains, in the summer of 1891 ; 

 common in willow thickets from the mouth of Slave River to 

 Peace River Landing, Lat. 56° 15' in June, 1903 ; first seen on 

 May 22nd, 1897, ^t Edmonton, Alta.; tolerably common along the 

 creeks by the 28th; no doubt they breed here ; common from 

 Edmonton to the Athabasca Pass in willow thickets in low 

 grounds and along streams in June, 1898 ; common in the 

 foothills south of Calgary. {Spreadborough.) Common at the. 

 Grand Rapids of the Saskatchewan, where it doubtless breeds. 

 {Nutting.) One of the most abundant birds between Athabasca 

 Landing and Lesser Slave River; first noted May 30th ; common 

 down the Athabasca River to Fort McMurray, Lat. 56° 40' ; com- 

 mon up the Clearwater River and at the north end of Methye 

 Portage; common between Methye Lake and Isle a la Crosse 

 Lake ; last seen August loth. (/. M. Macoun.) One specimen 

 only was procured at Cumberland House, on the banks of the 

 Saskatchewan, in the latter end of May. {^Richardson.) North to 

 Fort Simpson on the Mackenzie River. {Ross.) I have a nest 

 and four eggs of this bird collected at Fort Saskatchewan near 

 Edmonton, Alta., on June I2th, 1899, by Mr. J. Callaghan; nest in 

 a willow two feet from the ground. {W. Raine.) This was a 

 common breeder at 158-Mile House, B.C., where its sharp insistent 

 song was to be heard from every copse in the partially wooded 

 district. ' {Brooks.) Found only at Caribou Crossing, Lat. 60°, 

 B.C., where I heard four males singing and secured three of them, 

 June 27th and 28th, 1899. They were in comparatively open wil- 

 low and spruce swamps. {Bishop.)
