summer resident in the vicinity of Ottawa. {Ottawa Naturalist^ 

 Vol. V.) A very common warbler about Lansdowne, Leeds Co.j 

 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.) 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 Fac- 

 tory, 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. {Spreadborou^h.) Generally abundant about 

 Toronto. I have found it in great abundance in all suitable 

 places near Peterborough, Ont. (/. Hughes-Samuel.) Common 

 summer resident at Guelph, Ont. Arrives about May loth and 

 leaves about September i6th. {A. B. Klugk.) 



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. {Tkompson-Seton) This is a common breeding summer 

 resident at Avenue, Manitoba; arrives about May 20th and stays 

 toSeptember. {Norman Criddle .) This is a common summer resid- 

 ent at Indian Head, Assa.; it was first seen May, 21st, 1892, and 

 became common in a few days; they breed in considerable num- 

 bers, nesting in rushes about a foot from the ground on the edge 

 of small lakes; first seen at Medicine Hat, Assa., 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 Moun- 

 tain, Assa., June 6th, 1895; ^^ter in the month it was taken on 

 Rocky Creek near the 49th parallel and on Frenchman's River; 

 it was common in the Cypress Hills wherever there was brush, and
