Wyoming Birds. 71 



646a. Vermivora celata lutescens: Lutescent Warbler. 



"The data regarding this variety is insufficient to warrant 

 an expression as to the extent of its occurrence in the 

 state." (Knight.) Lockwood thinks he has found it in 

 Albany County. Knight gives a few authentic records. 



647. Vermivora peregrina: Tennessee Warbler. 



Knight records it as accidental. Peabody is the only re- 

 cent observer who records it. 



648a. Compsothlypis americana usneae: Northern Parula War- 

 bler. 

 The recent A. O. U. list records it as casual in Wyoming 

 and Colorado. They have probably based their statement 

 on Knight's record of 648, in which he stated it was acci- 

 dental; there being but two records of the Parula Warbler 

 jn Wyoming. 



652. Dendroica aestive aestiva: Yellow Warbler. 



Abundant at all the lower and middle altitudes where it 

 can find brush or timber suitable for nesting. 



654. Dendroica caerulescens caerulescens: Black-throated Blue 



Warlbler. 

 Mr. Lockwood reports that in 1893 he took a specimen at 

 Casper. 



655. Dendroica coronata: Myrtle Warbler. 



The only recent records are by Richard, who reports that 

 they are common about Cody during migrations ; and by 

 Sawyer, who reported it from the Laramie Hills. Knight 

 said migratory, and rather uncommon, and cited a few 

 references. 



656. Dendroica auduboni auduboni: Audubon's Warbler. 



Common breeder in the lower timbered regions of the. 

 mountains. 



659. Dendroica pennsylvanica: 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." (Knight.)
