eggs at Red Creek Canon, May 10, 1876. C. N. Holden took 

 young birds on Turkey Creek about July 12, 1872. 



Regulus satrapa olivaceus. Western Golden-crowned King- 

 let. 



Winter resident ; not common. 



Tiiis species is found mainly in the mountains and foot- 

 hills, and at the bluffs. We have no records of it along the 

 valley streams. It ranges high in the mountains, Warren find-

 volume of the song is remarkable when the small size of the 

 singer is considered. Aiken made the following note on its 

 song at Divide, Teller County: "A Ruby-crowned Kinglet

 Widdie Widdie Widdie Widdie Widdie Widdie Widdie. The 

 whole uttered rapidly and in monotonous key except the last 

 'Widdie' which had rising inflection." 



Polioptila caerulea obscura. Western Gnatcatcher. 



Rare; but few records for the County. "Seen May 6, and 

 killed May 7, 1872, on Turkey Creek. Rather common for a
