CATALOGUE OF CANADIAN BIRDS. 635 
Vancouver island, associating with auduboni. (Streator.) An 
abundant summer resident. (fannin.) Tolerably common mi- 
grant at Chilliwack, B.C. (Brooks.) Found associating with 
audubont on Vancouver island; not seen east of the Coast range. 
(Rhoads.) This species is the hardiest of American warblers. In 
Alaska it breeds to the northern tree limit, considerably within the 
Arctic circle. (Nelson.) My specimens of this species were obtained 
at Fort Yukon where they breed. I observed this species at Nush- 
agak, Bristol bay, in June, 1878, where it was quite abundant 
among the willow thickets along the river. (Turner.) We found 
Hoover’s warblers at Skagway, Glacier, Log Cabin and Haine 
Mission, on the Lynn canal and White pass; also Bennett, Cariboo 
Crossing, Lake Tagish, Miles cafion, White river, Sixty-mile creek, 
and 12 miles above Circle City,in the Yukon valley. (Bishop.) A 
single adult male was taken June 23rd, 1897, and a few others heard 
previously in the dense firs along Indian river, Sitka. (Grinnelil.) 
Two specimens were seen during June and July and several during 
August and September, 1901. One was taken on the Kenai mount- 
tains, August 17th, and one at Sheep creek, August 18th. (Figgins.) 
Several specimens taken at Seldovia and Sheep creek, Alaska, in 
1903. (Anderson.) 
BREEDING NotTes.—Hoover’s warblers were numerous summer 
residents of the timber tracts throughout the Kowak valley from 
the delta eastward; in the latter part of August scattering com- 
panies were frequenting the spruce, birch and cottonwoods, among 
the foilage of which they were constantly searching, with oft-re- 
peated ‘‘chits,’’ just as are their habits in winter in California; the 
last observed, a straggling flock of six or eight, was seen in a patch 
of tall willows about sunset of August 30th; the following spring 
the arrival of Hoover’s warblers was on May 22nd; they were 
already in pairs and the males were in full song; at this season they 
were confined exclusively to the heavier spruce woods; in the 
Kowak delta, on the 23rd of June, a set of five considerably in- 
cubated eggs was secured; the nest was in a small spruce in a tract 
of larger growth, and only four feet above the ground; it is a rather 
loose structure of fine, dry grass-blades, lined with ptarmigan 
feathers; the colour of the eggs is an extremely pale creamy tint, 
almost white, with wreaths about the big ends of large lavender 
blotches, and smaller spots of drab, overlaid by a few Vandyke 
brown. (J. Grinnell.)
