two, (nos. 9449, 9450), Etolin Island, four (nos. 9451-9454), 

 Bradfield Canal, two (nos. 9455, 9456), Zarembo Island, one, 

 (no. 9457), Mitkof Island, one (no. 9458), and the Taku River, 

 two (nos. 9459, 9460). 



Nos. 9452-9454, 9457 are in juvenal plumage, while nos. 9459, 

 9460, male and female, Taku River, September 10 and 12, are in 

 complete first winter plumage, and apparently indistinguishable 

 from adults. No. 9458, adult male, Mitkof Island, August 9, is 

 in the midst of the annual molt. 



Regulus calendula grinnelli Palmer. Sitka Kinglet. 



Though seen throughout the region at many scattered points, 

 the Sitka kinglet was nowhere at all common until late in the 

 summer, when the young birds were flying about and the south- 

 ward migration had begun. Single individuals were observed 

 at various points on Kupreanof , Kuiu, Prince of "Wales, Corona- 

 tion, and Warren islands, and at Boca de Quadra and the 

 Chickamin River on the mainland. On Mitkof Island, August 1 

 to 13, they were seen occasionally in the alders along the beach, 

 evidently migrating and they were subsequently met with in 

 steadily increasing numbers at Thomas Bay and Port Snettisham. 

 On the Taku River, during September, they were seen daily, 

 being far more abundant than at any other point. The character 

 of the vegetation may have had something to do with their 

 abundance here as they were almost always found in the alders 

 or in other deciduous trees dr shrubs, such as grow in abundance 

 at this point, while the golden-crowned kinglet evinced a marked 

 preference for the conifers. 



A series of twenty-five specimens was secured (nos. 9421- 

 9445). Of these two are adult males, nos. 9421, 9422, from Kuiu 

 and Warren islands, respectively. Eleven are juvenals, nos. 

 9423-9432, 9436, and twelve, all from the Taku River, are imma- 

 tures in complete first winter plumage. Some young birds taken 

 the middle of August are already beginning to molt into this 

 plumage, but one shot on September 9 (no. 9436) is still in the 

 juvenal plumage throughout. Of the twelve in first winter 

 plumage, eleven are males. 



The juvenals are appreciably darker than specimens of
