SAXICOLIDiE. 



4. Sialia mexicana Swains. Western Blue Bird. None seen 

 until the last of September, when I found them common about a hill 

 covered with dead pines. The last of October they became abun- 

 dant about the ranches, and the last of November migrated in strag- 

 gling flocks. 



& SYLvinm 



5. Regulus calendula Licht. Ruby-crowned Wren. First 

 taken the last of September; from then until the first of December 

 they were common about the pine thickets and chaparral bushes 

 along the borders of woods, busily searching for insects, as in the East. 



CHAM^IDiE. 



6. Chamsea fasciata Gambel. Ground Tit. Saw a pair in 

 November. They were quite difficult to shoot as they kept on the 

 opposite side of the bushes. 



7. Lophophanes inornatus Cassin. Gray Titmouse. Not 

 common until the first of October, after which they became more 

 and more numerous until in November they were the most common 

 bird. Almost invariably found in oak woods, and always busy 

 searching the branches for insects. They would tap the branches 

 like a woodpecker, making such a loud noise that I often mistook 

 them for the western Downy Woodpecker, P. Gairdneri. 



8. Parus atricapillus var. oceidentalis Coues. Western 

 Titmouse. Shot two specimens in the pines higher up the mountains 

 in November. 



9. Psaltriparus minimus Bonap. Least Tit. First taken in 

 October. From the middle of October to the first of December, they 

 were exceedingly abundant in large flocks; I have seen as many as 

 two hundred in one flock. They frequent hillsides covered with 

 chaparral, and are very unsuspicious, allowing a person to approach 

 within a few feet of them. While standing in the bushes I have 

 often had a whole flock assemble around me and act as though they 

 were curious to know what I was doing. Their faint piping note has 

 a far away sound and at first often deceives one as to the distance 

 the bird is from him. 



CERTHIID^. 



10. Certhia familiaris Linn. Creeper. Bare during August, 

 but became common the last of September, and had all migrated by 

 the last of November.
