WYOMING Birps. 123 
738. Mountain Chickadee. Common resident. During the winter 
this form works downward and replaces septentrionalis, 
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 ferm are both found here. 
About one of migratorius to 25 of propinquus. . 
76la. 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, 
197, 334, 388, 448, 459, 515, 646, 725¢, 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.
