683a. Icteria virens longicauda: Long-tailed Chat. 



Rather common summer resident over most of the state at 

 the lower altitudes where they can find suitable brushy 

 streams. 



685. Wilsonia pusilla pusilla: Wilson's Warbler. 



Knight reported that it is a summer resident not uncom- 

 mon. Most of the recent observers have reported the 

 Pileolated Warbler as quite common. If there is a recog- 

 nizable form such as pileolata, it certainly occurs in this 

 region. 



685a. Wilsonia pusilla pileolata: Pileolated Warbler. 



Abundant summer resident and ranging well up into the 

 mountains. (See comments under the preceding species.) 



687. Setophaga ruticilla: Redstart. 



Knight recorded it as an uncommon summer resident and 

 cited a few occurrences. Metz is the only recent observer 

 who records it. 



MOTACILLIDAE (Wagtails). 

 The Pipits live at high altitudes and are of but slight economic 

 importance in Wyoming, except during migrations, when they de- 

 scend to the lower altitudes and catch many insects.

697. Anthus rubescens: Pipit. 



Knight said this was probably a summer resident and quite 

 abundant in marshy places during the spring. Walker has 

 found it breeding abundantly above timber line in alpine 

 meadows in July. Jewett, Metz, Peabody, and Blackwelder 

 record it. 



700. Anthus spraQuei: Sprague's Pipit. 



"Thus far this species has been reported only by Mr. Bond 

 of Cheyenne, who has two skins in his collection that were 

 taken April 24, 1888. This will probably prove a rare spe- 

 cies in Wyoming, but not accidental." (Knight.)
