 "Certhia mexicana," Cooper, Oin. Cal., I, 1870, 58. 



The distribution of this species corresponds with that of Regulus calen- 

 dula, the pine forests being its home in summer, while in winter it performs 

 a partial migration to the timbered portions of the lower valleys, or to the 

 lower edge of the coniferous belt. It was first observed among the western 

 foot-hills of the Sierra Nevada, where it was seen early in July, at the very 

 commencement of the pine forest. In winter it was more or less common 

 among the cotton-woods in the lower portion of the valleys of the Truckee 

 and Carson Rivers, but eastward of those localities it was not again met 

 with at any season, except on the Wahsatch and Uintah Mountains, where 

 it was a rather common summer resident in the pine-region.
