May 22nd and was thenceforward common, especialh' in the Kowak delta in June. 

 But it was not detected west of the tree-limit. The native name of this bird is 

 Ik-sik-ti'o^ok. The following table of measurements of Stiurus iioveboraccnsis nota- 

 bilis is from ni}" Kowak Valley s[)ecimens. 



]\lho)iia pnsilla (Wils.). 

 Wjlsox's Warbler. 



l.ike the Black-poll Waibler this species was not detected in the fall, and 

 oorresp(-ndingl3' was not seen in the spring until quite late, W'ilscn's Warblers 

 were first noted at our winter camp on the Kowak on June 3rd. when three were 

 seen, and a male secured. They did not, however, become common, and but few 

 were seen afterward. In the Kowak delta one was observed on June 12. The 

 denser willow thickets seemed to be the preferred haunts of this warbler. 



Jhidyicsjiavus leucostriatiis (Hom.). 

 SiBERi.'VN Yellow Wagtail. 



The Yellow Wagtail proved to be an abundant summer bird of the c< a^t 

 region of Kotzebue Sound. I saw it on the tundras of the Kowak delta l:ordering 

 the eastern shore of Hothani Inlet, within a radius of eight miles of Cape Blossom, 

 and on Chamisso Island. The minute I first landed at Cape Jjlossom, i A. ji.. July 

 <9, '98, I was attracted b3^ a bird which flew in a hesitating manner in liroad circles 

 .above the beach, which at this point rose abruptly to a gra.s.S3' bank with a low 

 growth of brush at the top. The bird uttered a faint "pe-weet" at frequent inter- 

 vals, and its general demeanor reminded me strong!}' of our American Pipit. On 

 July loth I rowed several miles up a winding lagoon, an<l during the day I saw 

 .several pairs of wagtails. Thej- were always shy, flying falteringly high over- 

 head, l)Ut from their n(;tes of anxious tone and general bearing, I judged they liad 

 nests in the neighborhood. The first of the .sptcies I secured was a nearl3'-fledged 

 juvenile on Jul}' i8th. It was flushed from the weedy border of a dwarf alder 

 thicket near a jioiid. On Juh- 20th, duringa tramp along the coast southeasterly, I 

 :saw several squads of three to six full-grown juveniles. The southern faces of the 

 low blufi^'s still held large snow-banks, and where these were melting the ground 

 was muddy and much vegetation was just s])ringing uj).. At the.se oases the little 

 groups of wagtails were most often encountered. On July 28th, I took a lor.g 

 walk into the interior of the peninsula over the hills and tundras. Although 

 juveniles were common enougli along the beaches I met with none further than a
