couver Island, associating with Awdubont. (Streator.) An abun- 
dant summer resident. (/anmin.) Tolerably common migrant at 
Chilliwack, B.C. (Bvooks.) Found associating with Amduboni on 
Vancouver Island; not seen east of the Coast Range. (Rhoads.) 
This spceies is the hardiest of American warblers. In Alaska it 
breeds to the northern tree limit, considerably within the Arctic 
Circle. (JVelson.) 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. (Zurner.) We found 
Hoover’s warblers at Skagway, Glacier, Log Cabin and Haine’s 
Mission, on the Lynn Canal and White Pass; also Bennett, Caribou 
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. (Grinnell.) 
BREEDING Notes.—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 foliage of which they were constantly searching, with oft- 
repeated ‘‘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 incubated eggs was secured ; the nest wasin 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 color of the eggs isan extreme- 
ly pale creamy tint, almost white, with wreaths about the big ends 
of large lavender blotches, and smaller spots of drab, overlaid by 
afew Vandyke brown. (/. Grinnell.)
