in a bluff. {W. Raine.) This is a rare species at Aweme, Man. ; 

 probably breeding. (Criddle.) A single individual of this species 

 was kiUed 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
