Anthus rubescens (Tunstall). American Pipit. 



Observed at comparatively few points. At Kupreanof Island 

 on April 21, a small flock was seen on a sand bar near the camp. 

 At Calder Bay, Prince of Wales Island, May 11 and 12, several 

 small companies were flushed from the grass on the beach, while 

 at Egg Harbor, Coronation Island, scattered individuals were 

 observed, also along the beach. The species was then lost sight 

 of until we reached Marten Arm, Boca de Quadra, where, on 

 June 9, large flocks were encountered on the meadows, evidently 

 still migrating. It was next seen on the Taku River, September 

 4 to 28, single birds being occasionally met with along the banks 

 of the stream. 



"" Two specimens were secured, an adult male from Egg Harbor, 

 Coronation Island (no. 9461), and an immature male (in complete 

 first winter plumage) from the Taku River (no. 9462). There is 

 singularly little difference in the color and markings of the two 

 birds. High plumaged old males from California have the lower 

 surface of the body distinctly einnamomeous and sometimes 

 almost entirely devoid of black streaking, while winter birds are 

 entirely devoid of this cinnamon tinge. This Alaskan immature 

 is quite as einnamomeous below as is the adult, and there is 

 practically no difference between the two in the character and 

 extent of the black streakings. 



Cinclus mexicanus unicolof Bonaparte. American Dipper. 



A single bird seen by Hasselborg on May 11 on a stream 

 emptying into Calder Bay, Prince of Wales Island. This is 

 the only occasion on which the species was met with during the 

 entire summer. 



Nannus hiemalis pacificus (Baird). Western Winter Wren. 



Quite generally distributed over the region but common 

 nowhere until the young birds began to appear, toward the end 

 of July. The first was seen at Three-mile Arm, Kuiu Island, 

 April 29. On Prince of Wales Island, at Port Protection and 

 Calder Bay, one or two were heard singing in the woods. Several 

 were observed on Coronation Island. On Warren Island one was
