the Duck Mountains where I shot a male onjune-ioth, 1884. 

 {Thompson-Seton.) First seen at Avenue, Manitoba, April 20th, 

 1903, became common by May 14th, 1903, last seen October loth. 

 {ISiorman Criddle.) This bird arrives on the banks of the Sas- 

 katchewan at Prince Albert in May and breeds in thickets. {Cou- 

 beaux) Abundant at Grand Rapids and Chemawawin; breeding 

 in the latter place. {Nutting.) I have the nest and four eggs 

 with the parent bird that were collected at Red River, Alberta, 

 June 14th, 1898, by Mr. W. Wenman. {W.Raine.) This is a 

 common migrant at Indian Head, Assa., it was first seen on April 

 25th, and the last ones disappeared on June 2nd, 1892; first seen 

 on April 30th, 1894, at Medicine Hat, Assa. Those shot were all 

 males. By May lith they were very abundant in willow thickets, 

 but were all gone by the i8th; observed two at the upper crossing 

 of the Lob-stick River, Alta., June 17th, 1898, where they were 

 breeding; seen in large 'flocks at the Henry House, September 

 2nd; a spring migrant at Banff, Rocky Mountains ih 1891; arrived 

 at Revelstoke, B.C., April 24th, 1890, but soon disappeared; a few 

 seen at Trail near the International Boundary in 1902, but all soon 

 disappeared. {Spreadborough.) 



This bird arrives on the banks of the Saskatchewan about the 

 middle of May and continues there all summer, frequenting 

 ■willow thickets and the borders of streams and lakes, where 

 Mfrica Gale grows in abundance. {Richardson.) North to La- 

 pierre's Hous--, on the Mackenzie River. {Ross.) This warbler 

 is not numerous on the Anderson River, where some thirteen nests 

 were found built on low spruce trees and a few on the ground. 

 It lays from four to five eggs. {Macfarlane^ 



Breeding Notes. — This bird occasionally breeds in central and 

 northern Ontarro, and commonly north of the Ottawa River. It 

 is recorded as doing so at Listowell, Ont., by Mr. Wm. L. Kells. 

 In the early spring and again in the fall when on migration it is 

 one of the commonest of the warblers ; the first nest I found was 

 in the spring of 1889, on 29th May, on the bank of Calabogie Lake, 

 Renfrew Co.; it was built near the top of a cedar agaiffst the stem, 

 about eight or nine feet from the ground and close to the water, 

 and on that date contained four fresh eggs; I easily identified the 

 bird by its white throat and other characteristic markings; though 

 I often saw the bird in the interval I did not again meet with its 

 nest until June nth, 1902, when I found a nest in a second growth
