CATALOGUE OF CANADIAN BIRDS. 605 



couver Island, associating with Audubopi. {Streator.) An abun- 

 dant summer resident. {Fannin.) Tolerably common migrant at 

 Chilliwack, B.C. {Brooks) Found associating with Auduboni 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. {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. {Ttirner.) 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 Canon, 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. {Gtinnell.) 



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 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 color of the eggs is an extreme- 

 ly 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. (/. Grinnell)
