 20, 1878. It is an abundant summer resident at Stockton, Murphy's, 

 and Marysville. Two were seen at Big Trees in May, 1877, and one at

* 101. Myiarchus cinerascens, Lawr. — Ash-throated Flycatcher. 



The Ash-throated Flycatcher was first seen at Murphy's April 17, 

 1877 ; at Stockton Ajiril 27, 1878, where it was abundant in the thickets 

 by the San Joaquin Eiver during the first half of May. A few were 

 seen there afterward, and these may have had nests, although I have 

 generally found them during the breeding season in oal- groves. 



It is quite a common summer resident at Stockton and Murphy's, and 

 a young one was shot at Big Trees August 10, 1878. It was very rare 

 at Murphy's August 27, 1878. It was not seen at Stockton on or after 

 September 7.

*102. Sayornis nigricans, (Swains.)- — Black Peivee. 



This bird is a common constant resident of Stockton, Murphj-'s, and 

 Marysville. It frequented the willows by the streams in the meadows 

 at and near Big Trees in July and August, 1878. Since it was oftener 

 seen in August than in July, it may have made a short vertical migra- 

 tion from lower down after the breeding season.
