Wyoming Birds. 123 



738. Mountain Chickadee. Common resident. During the winter 

 this form works downward and replaces septcntrionalis, 

 which goes southward. 



748. Golden-crowned Kinglet. Mr. Sweeney reported to me that 



on October 2nd, 1912, he noted a small flock at Foxpark. 

 Apparently this form is very rare throughout this region. 



749. Ruby-crowned Kinglet. Very abundant summer resident. In 



all the heavy timber. 

 754. Townsend's Solitaire. Common summer resident. 

 756a. Willow Thrush. Common summer resident. 

 758a. Olive-backed Thrush. This form is probably more common 



than the preceding. 

 761. Robin. This and the following form are both found here. 



About one of migratorius to 25 of propinquus. 

 761a. Western Robin. Very common summer resident. 

 768. Mountain Bluebird. Abundant summer resident. 

 I. S. English Sparrow. Very abundant nuisance about the towns. 



Many are found about the ranches, but gradually spreading 



to the settled regions. 



COMMENTS. 



This list, by Walker, contains but- a single new species, 

 No. 387. The record is based upon a specimen which was 

 found dead on the University campus and is now in the 

 Wyoming collection of skins. 



Several species included here are rare, as for example, 

 T 97> 334. 388, 448, 459, 515, 646, 725c, and 748. 



The Wilson's Snipe, No. 230, and the Pipit, No. 697, are 

 reported to be summer residents for the first time. 



It is worthy of note that the Lazuli Bunting is becoming 

 more abundant and extending its range. It, no doubt, is a 

 summer resident.
