Vermivora celata orestera Oberholser. Rocky Mountain Orange- 

 crowned Warbler 

 Warblers of this species are rare in the upper Stikine Valley, or 

 else they are so secretive during the nesting season as to avoid observa- 

 tion. Two males (nos. 40145, 40146) were taken near Telegraph Creek 

 on May 27 and 31, respectively, probably migrants, and no more were 

 seen for some time. At Doch-da-on Creek, July 18, when many birds 

 were beginning to move about after the close of the nesting season, a 

 female in juvenal plumage (no. 40147) was obtained. Another young 

 bird, molting into first winter plumage (no. 40148) was taken at 

 Great Glacier, August 11. 



The two adults, compared with Vermivora celata lutescens of the 

 coast region, are of greater size and duller coloration. Compared 

 with v. c. celata, they are more yellowish, and lack the grayish tinge 

 of that race. Thus they exhibit the characters ascribed to Vermivora 

 celata orestera Oberholser (1905, p. 242 ; 19176/ p. 326) . The juvenals 

 may be distinguished from young lutescens by their gray juvenal 

 feathers, yellow in the latter race. 



Vermivora celata lutescens (Ridgway). Lutescent Warbler 

 An immature male just finishing the molt from the juvenal 

 plumage (no. 40149) was taken at Great Glacier, August 11. At 

 Sergief Island some were seen almost daily, evidently migrating and 

 usually in company with other transient warblers and kinglets. Five 

 specimens were taken, all immg-ture, on dates ranging from August 18 

 to September 22 (nos. 40150-40154). 



Vermivora peregrina (Wilson) . Tennessee Warbler ' 

 Met with on but one occasion. On June 12, at a point some five 

 miles southwest of Telegraph Creek, my attention was drawn to an 

 unfamiliar, wheezy song, heard at the edge of a swamp. The singer 

 was discovered flitting from one twig to another in rather slow, vireo- 

 like manner, giving his song at frequent intervals. It proved to be an 

 adult male Tennessee warbler, and was undoubtedly nesting near-by. 

 This specimen (no. 40155) was the only one taken or observed, although 

 I kept careful watch for the species from that time on.
