CATALOGUE OF CANADIAN BIRDS. 669 
Vol. V.) A very common warbler about Lansdowne, Leeds county, 
Ont., where after the yellow warbler it is the most frequently seen 
of all others. I have found its nest several times, usually built in 
long grass and brush a little above the ground, sometimes as much 
as twelve inches. I have seen eggs in May, June and July. This 
species was also common on the borders of a marsh on Amherst 
island, Lake Ontario. (Rev. C. J. Young.) Regular migrant at 
Toronto, Ont., common; rare summer resident. A fairly common 
summer resident in Parry Sound and Muskoka districts; arrives 
about the same time as the mourning warbler. (J. H. Fleming.) 
Only one individual observed on Moose river, near Moose Factory, 
June 7th, 1896; not common in Algonquin Park, Ont.; found 
in low wet ground amongst grass and low bushes. Saw a nest 
with four young about a week old in a clump of grass in a marsh 
on June 26th, 1900. (Spreadborough.) Generally abundant about 
Toronto. I have found it in great abundance in all suitable places 
near Peterborough, Ont. (J. Hughes-Samuel.) Common summer 
resident at Guelph, Ont. Arrives about May roth and leaves about 
September 16th. (A. B. Klugh.) 
Observed at Pembina, on Turtle mountain, and in the Rocky 
mountains, but not in the open country between these points. 
(Coues.) An abundant summer resident in the wooded portions of 
Manitoba; the Maryland yellowthroat is an abundant resident at 
Duck mountain, Man.; its favourite haunts are low damp thickets, 
so that it is in a measure the complementary species of the mourn- 
ing warbler, which manifests a liking for none but the driest of 
copses. (E. T. Seton.) This is a common breeding summer 
resident at Aweme, Manitoba; arrives about May 20th and stays 
to September. (Criddle.) Regular and tolerably common migrant 
in Manitoba, breeding in suitable scrub and bush localities. (Atkin- 
son.) This is a summer resident at Indian Head, Sask.; it was 
first seen May 21st, 1892, and became common in a few days; they 
breed in considerable numbers, nesting in rushes about a foot from 
the ground on the edge of small lakes; first seen at Medicine Hat, 
Sask., May 15th, 1894, they never became common; late in June 
the same year they were very common in all the willow thickets 
bordering the upper branches of Swift Current creek in the east end 
of the Cypress hills; one specimen was shot at 12-Mile lake, near 
Wood mountain, Sask., June 6th, 1895; later in the month it was
