in a bluff. (W. Raine.) This is a rare species at Aweme, Man.; 
probably breeding. (Criddle.) A single individual of this species 
was killed in the woods at Cumberland 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 Notes.—Arriving generally about the middle of May 
these birds are mostly found in young second growth woods. 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.) Found 
a nest in Compton county, Que., June 12, 1904, deeply imbedded 
in the yielding side of a mound. It was a slight affair (the sur- 
rounding mosses rendering a more substantial structure unneces- 
sary) of withered grasses, moss and rootlets, containing four young 
a few days old. (L. M. Terrill.) 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.)

1896. 
First seen at Revelstoke, B.C., May 9th, 1890; the birds seemed 
to come from the west through the Eagle pass and not up the Colum- 
bia; came in great numbers on the 13th, but seemed to travel north- 
ward; at Robson they were found breeding 1,000 feet above the 
Columbia on June 26th, 1890; observed throughout the district 
between Trail and Kettle river, near the International Boundary, 
quite common at Trail where a nest was taken on May 24th, 1902, 
it was placed on the ground between two stones, overhung with 
grass; the nest was made of the inner bark of trees lined with hair
