the valley, in suitable localities, but I did not find it at Murphy's from 

 the middle of November, 1876, to May, 1877, though the following No- 

 vember and December it was abundant there. 



Its alarm-note is a short "chook," its call a prolonged, nearly 

 monotonous u chee," or "yee," and I have heard it sing sweetly about 

 March 1. I once mistook its call for the bleating of a distant lamb, 

 although the bird was not far from me.

* 3. Turdus ustulatus, Nutt. — Russet-backed Thrush. 



About a dozen of this species were seen in the willows at Marysville 

 in June, 1878, and there were probably many more, as their songs were 

 heard on several occasions in different parts of a thicket of willows, 

 briers, etc. I am not aware of meeting it elsewhere. Its delicious song 

 is not likely to be forgotten by one who has heard it.

4. Turdus guttatus, (Pall.).— Dwarf Thrush. 



The Dwarf Thrush is probably a constant resident at Stockton, as it 

 is common in winter and as late as June 8, 1878, at this time being 

 confined to thickets near water. In winter it is more generally dis- 

 tributed, being often seen in gardens. It, or a near relative, is abun- 

 dant at Murphy's in winter, and leaves that place in April.* 



It seems to be very rare in the Sierras in summer, during which I 

 have not been able to find it at Big Trees. Two or three were noticed 

 at Soda Springs, all of them on and after September 22, 1877.

*5. Mimus polyglottus, (Linn.). — Mocking-bird. 



A single bird of this species, in first plumage, was shot July 22, at 

 44 Big Tree Grove." It appears to be a constant resident of Marysville, 

 where it has long been known to breed. A pair were often seen by a 

 friend in Stockton during the past winter, and there are several young 

 birds here that were taken from their nests at Hornitos, Mariposa Co, 

 Still, it is by no moans a common bird in this region. 



A specimen was seen in a garden at Stockton on the 24th of Decem- 

 ber, 1878.
