"23. Chamaea fasciata, Gamb. — Ground lit 



This bird is a constant resident at Murphy's, Stockton, and Marys- 

 ville. At the two latter places it inhabits the willow thickets, where, 

 however, it is not numerous. It is very common at Murphy's in the 

 chaparral thickets. 



Its perfect spring song consists of three loud, high, staccato notes, 

 immediately followed by a trill, starting in the same key, gradually de- 

 scending about a minor third, the whole song occupying six or eight 

 seconds of time.

This Wren was quite common at Murphy's in February and the first 

 half of March, 1877. It was much given to penetrating the piles of 

 broken rocks in the abandoned mining claims, and was with difficulty 

 shot, and then at close range only. I have not seen it on the dry hills 

 frequented by Salpinctes obsoletus. I have observed it only at Murphy's, 

 at the time stated, and not elsewhere, though there is but little suitable 

 ground where I have been. There are many places on the Calaveras 

 River, in the chaparral belt, where it should be found, but these locali- 

 ties 1 have not visited in many years.
