ton, and a few, principally young of the year, visited Big Trees. August 

 20 of this year (1878). It was abundant in the middle of September 

 at Summit Meadows, and was quite common during the same month at 

 Soda Springs. I did not see it at Marysville in the winter of 1877-78. 



[Eespectiug the two species of Bluebirds. Mr. Belding writes, under date of Jan- 

 uary 15, as follows: — "Is it not remarkable that S. mexicana is now in the mountains 

 and S. arctica in the lowlands? The former more common than the latter, at least 

 when I left the valley. As snow is now two feet deep at Big Trees, S. mexicana has 

 probably left." — R. R.]

13. Regolas calendula, (Linn.).— Ruby-crowned Kinglet. 



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

 I have not seen it at Big- Trees in summer, though abundant at Soda 

 Springs the last of August and afterward. 



By the middle of April, 1878, it was very rare at Stockton. The first 

 seen the following fall was on the 3d of October.

* 14. Regulus satrapa, Licht. — Golden-crowned Kinglet 



This bird was seen on several occasions at and near Big Trees in July 

 and August, though not more than eight or nine in all. I had seen live 

 or six at Soda Springs about October 1, 1877, and about the same 

 number at Murphy's in December of the same year, but nowhere was it 

 so numerous as at Stockton. 



On the loth of November, 1877, I found a flock of thirty or forty as- 

 sociated with a smaller number of i?. calendula, and three days after- 

 ward saw a flock about as large about four miles from the spot where I 

 had seen those on the loth. These were also associated with a smaller 

 number of E. calendula.

*15. Polioptila ccerulea, (Linn. ). — Blue-gray Gnatcatchcr. 



This is a rather common summer resident of Murphy's, and it was 

 quite numerous at Marysville in June; at the former place frequenting 

 the chaparral, at the latter, the willows. It was first seen at Murphy's 

 April 5, 1878; at Stockton, March 23. It is rare at Stockton, and was 

 not seen there during the breeding season. Several were seen here in 

 August, 1877, but one was seen at Murphy's in parts of August and 

 September.
