502 APPENDIX. 



in all the northern and western parts of the State of California. About September 

 20, 1872, this species came in great numbers to the vicinity of San Buena- 

 ventura and remained there all winter, going to the mountains northward by 

 March 20. 



Folioptila melanura (I, 81). Dr. Cooper informs me that while he found 

 P. coerulea common in September, he saw none of this species near San Buena- 

 ventura until November 12, when small parties appeared moving westward from 

 the colder desert regions east of the mountains. They kept entirely in the arte- 

 misia thickets among the sandy and dryest tracts, never going into the high trees 

 like P. ccerulea. In form, color, restless habits, and scolding mew, this species is 

 said to be a perfect miniature and mimic of the Catbird. 



According to Captain Bendire the species is not common in Arizona, where he 

 met with three nests. "One before me, found July 25, 1872, fastened in a bunch 

 of mistletoe, or rather suspended in it, is composed of a species of wild hemp fibres 

 nicely woven together, and lined with a few feathers and exceedingly fine grass. 

 The nest is very neatly made : Outer diameter, 2 inches ; inner, l.GO ; depth, 1.50. 

 The number of eggs is five, ground-color pale green, with spots of light reddish- 

 brown color scattered over the egg. Measurement, .50 by .40 of an inch. Their 

 notes are a rather harsh twitter, kept up for some time. They are active little 

 birds, and are very restless. 



Chamaea fasciata (I, 84). Mr. Allen thinks that he saw this species in Col- 

 orado Territory. See Am. Nat. VI, June, 1872, and Bull. Mus. Comp. Zool. Ill, 

 No. G, p. 184.' 



Lophophanes inornatus (I, 91). Mr. Aiken has obtained this species in 

 El Paso Couuty, Colorado, where it is common, while Mr. Henshaw, the naturalist 

 of Lieutenant Wheeler's expedition, found it abundant in Southern Utah. These 

 Rocky Mountain specimens are much grayer and somewhat larger than those from 

 California. 



Parus rufescens (I, 104). Nests and eggs of a Parus which undoubtedly 

 belong to this species were found by Mr. William A. Cooper, at Santa Cruz, Cal. 

 One of these nests, sent to the Smithsonian Institution, was found about four 

 miles from Santa Cruz, April 22, 1873. The nest was composed of moss and fine 

 bark, largely intermingled with the fur of rabbits and other small quadrupeds. It 

 was built in a hole in the branch of a tree about ten feet from the around. The 

 branch was about half a foot in diameter and was partially decayed. The cavity 

 was about a foot in length from the nest to the place where the bird gained an 

 entrance, which was a small hole about an inch and a quarter in diameter. The 

 eggs were seven in number and contained partially formed embryos. They 

 measure .64 of an inch in length by .52 in breadth, resemble the eggs of the 

 atricapillus, but are more sparingly marked with spots, rather more minute and 

 of a lighter shade of reddish-brown, on a white ground. 



Sitta pygnicea (I, 120). This bird is probably a geographical form of S. pu- 

 silla, as suggested by Mr. Allen (Bull. Mus. Comp. Zool., Vol. Ill, No. G, 

 p. 115).
