borough}) Very abundant summer resident in thickets at Prince 

 Albert, Sask., arriving in May. {CoubeaUx) 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 Grieat 

 Bear Lake in Lat. 65° in the beginning of June. {Richardson.) 

 North to Lapierre's House on the Mackenzie River. {Ross.) 



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 composed of plant fibres, dried grasses, wool and hair. 

 {W. H. Moore) Nest found in a lilac bush was composed of vege- 

 table substance and down lined with hair and down, a very com- 

 pact 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 inside is white when not lined with 

 hairs. This warbler often adds a story to its nest to cover up a 

 cowbird's egg laid in the original nest. {Garneau) This bird builds 

 a neat and compact nest and generally places it high up on the 

 willows or in the forks of a small tree, rose bushes or wolf willow. 

 It is chiefly composed of dead leaves of grasses and carices, and 

 with a thick lining inside of small feathers, hairs and fine cottony 

 wool gathered from the catkins of willows; numerous nests of the 

 above character were detected in June, 1895, in southern Assini- 

 boia by the writer.
