'^Certhia mexicana," Cooper, Orn. Cal., I, 1870, 58. 



The distribution of this species coi-responds with that of Begulus calen- 



dvla, 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 tlie 



lower edire of the coniferous belt. It was first observed amonji;' the western 



foot-hills of the Sierra Nevada, where it was seen eai'ly 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.
