on the ground in a willow swamp in a clump of herbage on the 

 edge of Vermilion lake at Banff, Alberta. {W. Raine.) Nest, in 

 a hemlock tree near the ground in woods near Ottawa, composed 

 of dry moss and twigs compacted together; lined with fine fibre 

 and fine grass ; eggs 4, dull white, sprinkled with reddish and brown 

 dots towards the larger end where the markings form a circle, leaving 

 the extremity plain. (G. R. White.) This is a rare warbler in 

 Ontario; a nest was taken in the vicinity of Lansdowne, Leeds 

 county, in June, 1894 not very far from the St. Lawrence; there 

 were four eggs in this nest, which was built on the ground; they 

 were small and white, thickly marked with fine brick-red spots.

685a. Pileolated Warbler. 



Wilsonia pusilla pileolata (Pall.) Coues. 1880. 



Common at Sidley, B.C. in 1905 and at Douglas in 1906; rather 

 rare at Agassiz, B.C., in May, 1889; observed at Chilliwack, B.C. 

 and along that river to the head of Chilliwack lake in the summer 

 of 1901 ; first seen on May 7th, 1893, near Victoria, Vancouver 

 island, by the 14th they were common in all the willow thickets; 

 they were seen at Sooke, Nanaimo, Comox and other points and 

 are a common summer resident on the island. (Spreadborough.) 

 British Columbia. (Lord.) More common in the coast region than 

 in the interior; breeds. (Streator.) A common summer resident, 

 chiefly west of the Coast range. (Fannin.) A tolerably common 

 summer resident at Chilliwack. (Brooks.) As early as May 12th, 

 these birds have been found feeding their young in Oregon; from 

 this region it extends north and occupies the entire Pacific shore of 

 the Alaskan mainland. (Nelson.) An adult male was taken at 

 Sitka, Alaska, on August i8th and several others including juveniles 

 seen on August 2 ist ; they were in low brush along the shores of a 

 secluded bay where they possibly breed. (Grinnell.) We found 

 this the most abundant bird at Glacier, June 5-10, frequenting the 

 alder thickets from the valley as far as they extended up the hills; 

 I saw a yellow warbler I thought of this species on White pass sum- 

 mit, June 12th; pileolated warblers were common at Log Cabin, 

 Beimett, and Cariboo Crossing, and I am confident I heard them 

 singing at Lake Marsh; adult males from Glacier resemble normal
