southwestern Colorado than it is east of the range, where it was first dis- 

 covered in the State. It breeds locally but not uncommonly in western 

 Colorado and has been observed north to Rangely, where two were noted, 

 September 17, 1906, and to Elk Springs, Routt County, where one was seen 

 September 11, 1906 — the most northwestern record for the State (Cary). 

 East of the mountains the species has been recorded from Colorado Springs, 

 Loveland, Pueblo, Fort Lyon. Holly, and from Gaume's Ranch, Baca 

 County. It had been supposed that these records from the plains referred 

 to the plains form cryptus and the one from Gaume's Ranch was so re- 

 corded by Cary (Auk, XXVI, 1909, 184), as had been done previously by 

 Ridgway (Birds N. & Mid. Am., III. 1904, 555), for all the Bewick Wrens of 

 Colorado. An examination of the specimen taken by Smith at Holly, 

 May 23, 1907, shows it to be bairdi and makes it evident that all Bewick 

 Wrens in Colorado belong to the one form. 



Cistothorus stellaris. Short-billed Marsh AVren. — One was shot 

 October 23, 1907, and another seen the next day near Mosca — the first 

 record for Colorado and the only record for the species west of the moun- 

 tains (Cary). 



Certhia familiaris montana. Rocky Mountain Creeper. — Yuma, 

 October 22-25, 1904 (Patten). 



Sitta carolinensis nelsoni. Rocky Mountain Nuthatch. — The former 

 lists of Colorado birds have given the white-bellied Nuthatches under two 

 forms, carolinensis and aculeata. Both these names should be withdrawn 

 and in their place the above name should be employed for all the white- 

 bellied Nuthatches of Colorado. 



Baeolophus inornatus griseus. Gray Titmouse. — Common September 

 1906, in the Escalente Hills of Routt County — the most northern record 

 for the State (Cary). 



Psaltriparus plumbeus. Lead-colored Bush-Tit. — Two flocks, Sep- 

 tember 4 and 8, 1906, near Douglas Spring, Routt County — the most 

 northern record for the State (Cary). 



Polioptila caerulea obscura. Western Gnatcatcher. — In 1897, there 

 was no record for a Gnatcatcher in western Colorado. Now the records 

 have multiplied until it is known locally from many places north to Grand 

 Junction. Fairly common breeder near Cortez and near the Dolores River 

 in southwestern Montrose County, June and July 1907 (Cary); Grand 

 Junction, common, May 17, 1906 (Ferrill); Walsenburg, one, May 21, 1907 

 (Cary); Boulder, one May 12, 1905 (Henderson). This last is the most 

 northern record for Colorado. 



Myadestes townsendi. Townsend's Solitaire. — Eggs July 27, 1906, 

 near Arkins at 6200 feet altitude — nearly two thousand feet lower than 

 usual (Cary); Gaume's Ranch, Baca County, abundant November 26-29, 

 1907 (Cary); noted in migration at Yuma May 24-25 and September 6 to 

 November 5 (Patten). 



Hylocichla mustelina. Wood Thrush. — One, May 27, 1905, at Yuma 

 — the first record for the State (Patten).
