Dendroica coronata hooveri McGregor 



Alaska Myrtle Warbler 



A single individual secured at Qiiinn River Crossing on ]May 

 21. It was fl.ying about in the brush near the junction of AVheeler 

 Creek and the river. The discovery of the species migrating at 

 this late date is unusual. 



Dendroica auduboni auduboni (J. K. Townsend) 

 Audubon Warbler 



Distribution. — Noted at nearly every desert station visited. 

 During June it retired to the pine woods of the mountains, for 

 at that time, though we found it occurring commonly at higher 

 localities, it was apparently absent from stations intermediate 

 in altitude. This vertical migration was observed by Ridgway 

 (1877, p. 434), who asserts that its migratory movements in this 

 region are mainly, if not entirely of this character. The species 

 was breeding in Transition. 



Habits. — The song of the Audubon warbler was much in 

 evidence during July. A brilliantly plumaged male, observed 

 in a thicket of tall sagebrush continually uttered a note resem- 

 bling ' ' pick ! " " pick ! ' ' The syllable differed markedly from the 

 customary "tit" or "wit" of the species. 



Another individual was observed singing from one of the 

 uppermost tw^igs of a limber pine. Its head was tilted back- 

 ward during the song. After the rendition it would feed in the 

 foliage of the pine or fly a short distance to another tree, shortlv 

 repeating its song agam. 



Adults Avith juvenals were sparingly noted as early as July 

 10, and thereafter more commonly. By August they became 

 abundant. 



For discussion of a probable case of hybridization between 

 Dendroica auduboni auduboni and Dendroica coronata see Taylor
