This bird was first seen at Mnii)liy'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 hammoadi, Xantus. — HammontTs FJycaichci: 

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



out of which I have not seen it except when migi-ating. It arrived at 



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

 At the latter i)lace it was rare, and confined to the willow thickets on 



the river-bauks.

T^Tiile making this collection I have seen but two of these biids in 

 sju-ing 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 Selasphorus rtifus, but perhaps 

 the present species was among them.

This bird 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 Humming-birds were seen during 

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