1922] Swarth: Birds and Mammals of the Stikine Region 285 



I had the opportunity of comparing a selection of these skins with 

 European examples of B. g. garrula in the United States National 

 Museum. The color differences distinguishing the two forms were 

 readily apparent in the series thus brought together, and the differ- 

 ences appear to me to be sufficiently pronounced to justify the recogni- 

 tion of the American subspecies, pallidiceps. (Cf. Oberholser, 1917c, 

 p. 333.) 



"We collected seventeen specimens of the waxwing, nine adult males, 

 three adult females, four juvenal males,. and one juvenal female (nos. 

 40123-40139). 



Vireosylva gilva swainsoni (Baird) . Western Warbling Yireo 



Common in the poplar woods of the upper Stikine Valley. First 

 taken near Telegraph Creek on May 29 ; shortly after, the birds arrived 

 in numbers. They were seen daily at Glenora and Doeh-da-on Creek, 

 undoubtedly breeding at both places. When we arrived at Flood 

 Glacier, July 26, the species was present in some abundance; at the 

 time of our departure, August 8, the birds were nearly all gone. 

 Whether or not this vireo breeds at the last mentioned locality was 

 not definitely ascertained, but I am inclined to think that it does, 

 judging from the actions of certain individuals. On July 31 a pair 

 of the birds spent nearly the whole day in an alder thicket near our 

 camp, scolding continually at some disturber of their peace that I 

 could not discover. Possibly an owl was roosting near-by. Anyway, 

 the vireos acted much as though they were concerned over the safety 

 of their brood. 



At Great Glacier, August 10, two were seen. This was the latest 

 date of occurrence, and Great Glacier the westernmost locality at 

 which the species was noted. Our several points of record apparently 

 constitute the farthest known extension of the range of this sub- 

 species toward the northwest. It is not included by Anderson (1915a) 

 in his list of birds from Lake Atlin, some two hundred miles north 

 of Telegraph Creek. The occurrence at Great Glacier carries the 

 range to within ten miles of the Alaskan boundary, and to within 

 about thirty miles of the coast. 



Five adult specimens were collected, two from the vicinity of Tele- 

 graph Creek, one from Doch-da-on Creek, one from Flood Glacier, 

 and one from Great Glacier (nos. 40140-40144). These birds are in 

 no wise to be distinguished from others from more southern points 

 in the range of the subspecies, as in California.
