more common in Bruce county in summer. (IW. &. 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. (Ad. B. Klugh.) 
A rare summer resident of woodlands in Manitoba; on June 
11th, 1884, I found a Nashville warbler in full song and evidently 
breeding. (Zhompson-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 ina bluff. (W. Razie.) This is a rare species at 
Avenue, Manitoba; probably breeding. (Vorman Criddle.) A 
single individual of this species was killed in the woods at Cum- 
berland House, on May 15th, as it was hopping among the 
branches of a tree. (Richardson.) North to Fort Resolution on 
Great Slave Lake; rare. (Ross.) . 
BREEDING Nores.—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 amoist 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. ZH. 
Moore.) A nest containing two fresh eggs of this bird and two 
cowbird’s eggs was found near Ottawa, June Ist, 1899. It was 
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 1°50 and 2°10. (Garneau.)
