Dendroica striata (Porster). Black-poll Warbler. 



A single specimen, an immature female in complete first 

 winter plumage, secured on the Taku River, September 4 (no. 

 9533). It was in a mixed flock of warblers, kinglets, and 

 nuthatches, evidently migrating. Probably but a straggler from 

 the interior, as it was not previously known to occur in the coast 

 region, its southward line of migration lying east of the moun- 

 tains entirely. 



Dendroica townsendi (Townsend). Townsend Warbler. 



Nowhere very common in this region, though observed at 

 many scattered localities. The first was seen at Calder Bay, 

 Prince of Wales Island, on May 12, an adult male. Next 

 observed at Warren Island, where one was secured on May 21 

 and several others seen during the next few days. The species 

 was then lost sight of until Boca de Quadra was reached. Here 

 I secured the male bird of a pair which was possibly preparing 

 to breed in the vicinity, though they were the only ones seen 

 at this point. This individual, though a breeding bird, is not 

 in perfect, mature, plumage, the black of the throat being much 

 obscured by the yellow tips of the feathers. No more were 

 observed until we arrived at Mitkof Island, in August. By this 

 time the southward migration was under way, and an occasional 

 Townsend warbler could be seen in the flocks of small migrants 

 flitting along the shrubbery at the edge of the woods. At 

 Thomas Bay also they were seen almost daily, usually in the 

 alders, while on the Taku River occasional individuals were 

 seen up to September 14. 



Eight specimens were secured: adult male, Warren Island 

 (no. 9516) ; adult male, Boca de Quadra (no. 9517) ; adult 

 female, Mitkof Island (no. 9518) ; two immatures, Thomas Bay 

 (nos. 9519, 9520) ; three immatures, Taku River (nos. 9521-9523). 



The female from Mitkof Island (no. 9518, August 11) is in 

 the midst of the post nuptial molt. The immatures are all in 

 complete first winter plumage.
