64 ORUISE OF STEAMER CORWIN IN THE ARCTIC OCEAN. 
DENDRGCA CORONATA (Linn.) Gray. 
(20.) THE YELLOW-RuMP WARBLER 
Occurs as an occasional, but not rare, visitant along the American shore, perhaps most 
numerous along the shores of Norton Sougd. 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. 
DENDRG@CA STRIATA (Forst.) Baird. 
(21.) THe BLACK-POLL WARBLER. 
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 other 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 Michael’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 NZ:VIUS (Bodd) Coues. 
(22.) THE SMALL-BILLED WATER THRUSH. 
tather common about the shores of Norton Sound during the fall migration, which continues 
during the month of August. Although not numerous every season, yet from three to a dozen 
may be taken about the 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 great 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 honors with the larger Fox-colored 
Sparrow. 
MYRODIOCTES PUSILLUS (Wils.) Bp. 
(23.) Tor 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 Yukon 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 flies 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. 
LANIIDA.. SHRIKES. 
LANIUS BOREALIS Vieill. 
(24.) Toe GREAT NORTHERN SHRIKE. 
The Northern Shrike is a very rare visitant to the coast of Bering Sea, and except at the 
mouth of the Yukon and along the 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.
