were seen, almost always in small flocks together with migrating 

 kinglets and warblers. 



It is rather remarkable that during our whole stay on the 

 Taku River, September 4 to 28, not a single chickadee of any 

 kind was observed, though I had hoped from the many inland 

 forms which appeared from time to time, that I might find 

 P. a. turneri at this point, as well as P. rufescens. 



Twenty-one specimens of the chestnut-backed chickadee were 

 preserved, from the following localities : Kupreanof Island, eight 

 (nos. 9886-9393), Kuiu Island, two (nos. 9394, 9395), Prince of 

 Wales Island, three (nos, 9396, 9397, 9400), Coronation Island, 

 two (nos. 9398, 9399), all adults; and the following juvenals: 

 Etolin Island two (nos. 9401, 9402), Mitkof Island, two (nos. 

 9403-9404), and Thomas Bay, two (nos. 9405, 9406). 



Juvenals from IMitkof Island and Thomas Bay, shot on 

 August 11 and 16, are just beginning to molt into the first winter 

 plumage. 



Regulus satrapa olivaceus Baird. 

 Western Golden-crowned Kinglet. 



One of the few species of land birds that was fairly common, 

 and quite generally distributed over the region. The first, a 

 single bird, was seen April 12 on Kupreanof Island where occa- 

 sional small flocks were met with thereafter. A few were 

 observed on Kuiu Island, and also at the various points visited 

 on the north and west coasts of Prince of Wales and Dall islands. 

 On Coronation and Warren islands, in May, it was quite com- 

 mon and still in flocks. Several pairs were seen at Boca de 

 Quadra and the Chickamin River, on the mainland. The first 

 juvenals were observed on Etolin Island, July 6 to 12, several 

 small flocks being encountered, probably composed each of a 

 single family. The species was subsequently met with at Brad- 

 field Canal, Zarembo and Mitkof islands, Thomas Bay, Port 

 Snettisham, and the Taku River, at all these latter points being 

 gathered in small flocks, traveling southward, frequently in 

 company with migrating warblers. 



Fifteen specimens were collected: Kupreanof Island, one (no. 

 9446), Kuiu Island, two (9447, 9448), Prince of Wales Island,
