64 CRUISE OF STEAMER CORWIN IN THE ARCTIC OCEAN. 



DENDRCBCA CORONATA (Linn.) Gray. 



(20.) The Yellow-Rump Waebleb 



Occurs as an occasional, but not rare, visitant along the American shore, perhaps most 

 numerous along the shores of Norton Sound. It is, however, a woodland species, and makes but 

 very short stops along the inhospitable coast, but hastens to more congenial locations in the 

 interior, where it rears its young. In the autumnal migration it hastily seeks its more southern 

 haunts, and rarely lingers along the bare coast of the north, as do some of its relatives. 



DENDRCSCA STRIATA (Porst.) Baird. 



(21.) The Black-Poll Waebleb. 



Like the Yellow Rump, this is a rather scarce bird, and is found along the shore of Norton 

 Sound merely as a spring and fall migrant. It also occurs upon the shores of Kotzebue Sound 

 at the same season. Like otlier small birds, it frequents the vicinity of houses during its passage, 

 where it apparently finds the best foraging grounds. The small garden spot close to the kitchen at 

 Saint JNIichael's seems to be the great rendezvous and point of attraction for such of these small 

 species as pass that way in spring and fall. Like some of the other small birds mentioned, this is 

 a common interior species; it is unknown on the islands and Asiatic shore of the sea. 



SIURUS NiBVIUS (Bodd) Coues. 



(22.) The Small-Bllled Water Thrush. 



Rather common about the shores of Norton Sound during the fall migration, which continues 

 during the mouth of August. Although not numerous every season, yet from three to a dozen 

 may be taken about tiie muddy spots in the immediate vicinity of the houses at Saint Michael's. 

 It has not been taken on any of the islands in Bering Sea. These birds breed in the bushy islands 

 of the Lower Yukon in gi-eat abundance as well as in some of the more favorable thickets along the 

 coast of Norton Sound, ranging as high up at least as Kotzebue Sound. Their clear, rich notes 

 rise from the dense clumps of willows or alders in their favorite haunts in spring, enlivening the 

 river banks with their wild full tones and dividing the musical lionors with the larger Fox-colored 

 Sparrow. 



MYRODIOCTES PUSILLUS (Wila.) Bp. 



(23.) The Black-Capped Yellow Warbler. 



In companionship with the Yellow Warbler, this pretty little bird makes its summer home 

 among the bushy patches along the coast, especially from the Yukou mouth north to Kotzebue 

 Sound. Both this and the species just mentioned extend their summer haunts even to the 

 confines of the Arctic Circle. Both make pilgrimages in the winter to Mexico and Central 

 America, where they hob-nob and catch tiles with the stay-at home warblers and fly catchers of 

 the tropical forests, and after a season of recreation and plenty they betake themselves over the 

 thousands of miles intervening and arrive a merry, restless party at their nesting grounds early 

 in June or the last of May. They are unknown beyond the Alaskan mainland and are more 

 plentiful in the interior than on the coast. 



LANILD^. SHRIKES. 

 LANIUS BOREALIS Vieill. 



(24.) The Great Northern Shrike. 



The Northern Shrike is a very rare visitant to the coast of Bering Sea, and except at the 

 mouth of the Yukou and along tlie shores of Kotzebue and Norton Sounds its occurrence is very 

 unusual. In the places mentioned it must be classed as rare. The mouth of the Yukon is appar- 

 ently the point of most frequent occurrence, while elsewhere it is a mere straggler.
