the snowbirds and other species just come from the north. (Coues.) 
An abundant migrant; a few breed in Manitoba, at the Duck moun- 
tains where I shot a male on June 1oth, 1884. (EF. T. Seton.) First 
seen at Aweme, Manitoba, April 20th, 1903, became common by 
May 14th, 1903, last seen October 1oth. (Criddle.) One of the 
most migrating species in Manitoba, the first to come and the first 
to leave. (Atkinson.) 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, Sask.; 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, Sask. Those shot were all males. By May 11th 
they were very abundant in willow thickets, but were all gone by the 
18th; observed two at the upper crossing of the Lob-stick river, 
Alta., June 17th, 1898, where they were breeding; seen in large 
flocks at Henry House, September 2nd; a spring migrant at 
Banff, Rocky mountains in 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. (Spread- 
borough.) 
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 Myrica Gale 
grows in abundance. (Rtchardson.) North*to Lapierre House, 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. 
(Macjfarlane.) On September 3rd, 1907, a small flock appeared at 
Last woods, Artillery lake. This may be a northward fall migration. 
(E. T. Seton.) 
BREEDING Notes.—This bird occasionally breeds in central and 
northern Ontario, and commonly north of the Ottawa river. It 
is recorded as doing so at Listowel, 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
