more common in Bruce county in summer. (W. E. Saunders!) 

 Abundant as a migrant in spring, and fairly common in the fall; 

 breeds sparingly at Guelph, Ont.; arrives about May 12th, leaves 

 about September 22nd. {A. B. Klugh.) 



A rare summer resident of woodlands in Manitoba; on June 

 nth, 1884, I found a NashvHle warbler in full song and evidently 

 breeding. [Thompson- Seton.) At the south end of Lake Manitoba, 

 near Portage la Prairie, Man., on June 13th, 1894, I took a nest 

 and four eggs Of this species; the nest was built at the side of a 

 mossy knoll in a bluff. (W. Raine.) This is a rare species at 

 Avenue, Manitoba; probably breeding. {Norman Criddle.) A 

 single individual of this species was killed in the woods at Cum- 

 berland House, on May isth, as it was hopping among the 

 branches of a tree. {Richardson.) North to Fort Resolution on 

 Great Slave Lake; rare. {Ross.) 



Breeding NoxES.^Arriving generally about the middle of May 

 these birds are mostly found in young second growth wood. One 

 nest found was placed on the ground in a depression on the side 

 of a mound in a moist bush-grown pasture and was well concealed 

 by overhanging ferns, grasses and weeds, and was composed of ' 

 thin dried grass stems and moss, and was lined with fruit stems of 

 hair moss. It contained three fresh eggs July 15th. The bird 

 flew from the nest on being discovered and was silent and did not 

 appear for nearly an hour. This species is fairly common here, 

 but at St. John, Mr. Banks informs me they are rare. {W. H. 

 Moore.) A nest containing two fresh eggs of this bird and two 

 cowbird's eggs was found near Ottawa, June ist, 1899. ^^ ^^^ 

 built on the ground by the side of a log in a marshy place, and 

 made with green moss, grass and hairs. The bird left the nest 

 only after the log had been shaken a couple of times; nest 3'50 

 X 150 and 2"io. {Garn£au.)
