*108. Empidonax obscurus, (Swaius.). — lVri(jhfs Fl'.jcatchcr. 



This bird was first seen at Mnrphy's on April 28, 1877, at which time 

 it was rather common. It perched on the lower dead limbs of small 

 trees which grew on hillsides, from which it would make short flights 

 over the valley below, and return to the same perch. I have not recog- 

 nized it in the valleys.

*109. Empidonax hammondi, Xautus. — HammoncVs Flycatcher. 



This small Flycatcher is a common summer resident of the pine forests, 

 out of which I have not seen it except when migrating. It arrived at 

 Murphy's April 25, 1877, and at Stockton May 9, 1878. 



At the latter place it was rare, and confined to the willow thickets on 

 the river- banks.

While making- this collection I have seen but two of these birds in 

 spring plumage : these were at Murphy's, in April. It was very rare at 

 Big Trees in July and August. I have never seen it in the valleys. 



At Soda Springs, in the fall of 1877, Humming-birds were abundant. 

 I shot a number of them. They were young or moulting, and so did not 

 preserve them. They were principally Selmphorus rijfus, but perhaps 

 the present species was among them.

This l)ii'»l was common in the open parts of the willow thickets at 

 Marysville in June, 1878. It was not observed at Stockton from March 

 6 to June 8, though not more than five Humining-lnrds were seen during 

 that time, and five or six are all I have seen at Stockton during the pres-
