The Birds of Wyoming. 147 



656. Dendroica auduboni (Towns.). 

 Audubon's Warbler. 

 Summer resident and common in the pine forests. Breeds 

 most abundantly between 7,000 and 9,000 feet, and as low as 

 5,000 in northeastern Wyoming. Cooke cites this species 

 breeding above timber line ; but I have never seen this beau- 

 tiful bird above the limit of the pines, nor have I found it 

 breeding at timberline. It has been observed by all collectors 

 in Wyoming. Data too extended to warrant publishing. 



659. Dendroica pensylvanica (Linn.). 

 Chestnut-sided Warbler. 

 Probably accidental. The Wyoming record rests upon a 

 single specimen taken at Cheyenne, May 23, 1889, by Mr. 

 Frank Bond. Mr. Bond published this record in The Auk, 

 VI, 1889, 341, and has the skin in his collection. 



661. Dendroica striata (Forst.). 

 Black-Poll Warbler. 

 Possiblv a summer resident ; but no data. A very rare 

 eastern bird that occasionally reaches Wyoming. Jesurun re- 

 ports having taken it at Douglas, and Bond has two skins in 

 his collection that were taken at Cheyenne. Williston reports 

 ? single specimen taken at Lake Como. 



668. Dendroica townsendi (Towns.). 

 Townsend's Warbler. 

 Probably a summer resident in western Wyoming. The 

 only record of the occurrence of this bird in Wyoming comes- 

 from Dr. Jesurun. He took one specimen on Oct. 6, 1893, 

 and another on Sept. 25, 1894, at Douglas. These data ex- 

 tend the geographical range to the eastward for a consider- 

 able distance. 



675 a. Seiurus noveboracensis notabilis (Ridgw.). 

 Grinnell's Water-Thrush. 

 Probablv a summer resident. There are but little data 

 regarding this variety, the type of which was taken by Dr.
