common in the foothills south of Calgary; quite common and breed- 

 ing in large numbers at Banff, Rocky mountains, in the summer of 

 1891; common at Elko, B.C.; very common at Revelstoke and 

 Robson, on the Columbia river, in June, 1890; one nest was taken 

 in the fork of a cottonwood, 40 feet from the ground, on June 21st, 

 1890, containing four fresh eggs; a few were breeding at Trail, 

 near the International Boundary, in June, 1902; occasional at Kam- 

 loops and Spence Bridge, B.C. ; a few doubtful specimens at Victoria, 

 Vancouver island. (Spreadborough.) Very abundant summer resi- 

 dent in thickets at Prince Albert, Sask. ; arriving in May. (Cou- 

 beaux.) Common at Grand Rapids and at Chemawawin; breeding 

 in thickets. {Nutting.) Very abundant throughout the entire 

 wooded regions of arctic America, where it builds on dwarf willows 

 and small scrub pine at a height of a few feet from the ground. 

 (Macfarlane.) This species is known throughout the Northwest 

 Territories as far north as the woods extend, or to lat. 68°. It 

 reaches the banks of the Saskatchewan about the third week in 

 May, and Great Bear lake, in lat. 65°, in the beginning of June. 

 (Richardson.) North of Lapierre House, on the Mackenzie river. 

 (Ross.) Fairly common and nesting at Fort Resolution and thence 

 to the north shore of Great Slave lake, at least as far east as W. 

 long. 109° (E. T. Seton.) 



Breeding Notes.- — This warbler is very common along the St. 

 John river, near Fredericton. Have never seen them more than 

 a mile from a river or large stream where they nest in low bushes 

 that grow about such places. The nest is seldom over a yard from 

 the ground, and have often seen them within a yard of the highway 

 road. By the first week in June the majority of their eggs are laid, 

 three and four being the number in a clutch. The nest is com- 

 posed of plant fibres, dried grasses, wool and hair. (W. H. Moore.) 

 Nest found in a lilac bush was composed of vegetable substances 

 and down, lined with hair and down, a very compact and neat affair. 

 Eggs 5, grayish or greenish white dotted and blotched with reddish- 

 brown and lilac. (G. R. White.) Nests in bushes, conifers and 

 other trees around Ottawa. The nest is placed two to fifteen feet 

 from the ground, and composed of grayish fibres of plants and 

 vegetable down with a few bits of grass bark or feathers. The in- 

 side is white when not lined with hair. This warbler often adds a 

 story to its nest to cover up a cowbird's egg laid in the original nest.
