34. Dendrceca coronata, (Liim.). — Yellow-rum}? Warbler. 



This species appeared to be quite abundant at Murphy's in December, 



1877. I). a udubon i was also present, but less numerous than this species, 

 though their similarity at this season rendered their positive identifica- 

 tion difficult. It was also found at MarysvUle in January and February, 



1878, but it appeared to be less numerous than B. a udubon L In Febru- 

 ary it and many other small birds wore yellow throats and breasts, 

 which they acquired by feeding among the willows, which had just 

 blossomed.

'35. Dendrosca auduboni, (Towns.). — Audubon's Warbler. 



This bird is a very common winter sojourner in the valleys and foot- 

 hills. It undoubtedly breeds at Big Trees, where I have seen its young 

 scarcely able to lly, though at this time rather rare. It was abundant 

 at Soda Springs and Summit about October 1, 1877. It left Stockton 

 during the first week of May, 1878, in very warm weather, and returned 

 September 18. By October 6 it was common. 



It appears to be unable to endure very cold weather, as during a 

 freezing spell at Marvsville, in January of this year (1878), it was often 

 found unable to fly. One that I found in the streets in this condition 

 was soon restored by being warmed. Several dead ones were found in 

 the city.

"36. Dendrceca occidentalis, (Towns.). — Yellow-headed Gray Warbler. 



This species was more numerous at Big Trees in July, 1878, than all the 

 other Dendrcecee combined, and was rather common at Soda Springs in 

 August and September, 1877. In July and August, at Big Trees, it was 

 usually in the evergreens, though it was often, at all hours of the day, 

 in a thin strip of willows in the meadow, having apparently been drawn 

 there as much by the abundance of insects which swarmed in the willows 

 as by the water that flowed through them. There they would allow 

 me to go within a few yards of them, and were slow in learning to fear 

 a gun. 



At Big Trees, in May, 1877, this species frequented the deciduous oaks,
