It will thus be observed that the general fucks of the avlan-fauna of 

 the two remote regions is so similar that out of a total of 54 species noted 

 at Sacramento, only 4 are unrepresented in the eastern locality !' 



2. From the Sacramento River to the foot-hills of the Sierra Nevada (July 

 4-5). — This route lay across a rolling plain, of a character similar to 

 that described before, except that the monotony of the dusty landscape 

 was more frequently relieved by groves of low, spreading oaks, while occa- 

 sional spots near springs or along ruiniing streams were quite refreshing 

 from the cool shade they afforded. Such places were u.sually the site of a 

 ranche, and called to mind a country-place in one of the less-thickly wooded 

 portions of the Eastern States, the oak trees which, almost exclusively, 

 composed the groves being exceedingly similar in size and general appear- 

 ance to the white oak (Quercus alba). Among these trees sported the 

 California and Nuttall's Woodpeckers (Melanerpes formicivorus and Picus 

 nuttaUi), whole troops of chattering Yellow-billed i\Iagpies (Pica nuttalli), 

 and an occasional screeching Valley Jay {Cyanocitta californica). The other 

 species seen in these groves were the Ash-throated Flycatcher {Myiarchus 

 cincrascens), Lewis's Woodpecker {Melanerpes torquatus), Black-capped 

 Chickadee {Parus occidentalis), House Wren (Troglodytes parkmanni), Com- 

 mon Crow {Corvns americanus), Barn Owl (Strix pratincola), Mottled Owl 

 (Scops asio), and Red-breasted Hawk (Butco elegans); while on the plains, the 

 Horned Lark (Eremophila chrysolcema), Burrowing Owl (Speotyto hypoycea), 

 and Turkey Buzzard (Bhinogryphus aura) were observed. Nearly all these 



' The winter fauna would, of course, be considerably different from that observed 

 by us, on account of accessions from the r.inks of species which spend the summer in 

 the mountains or fartlier northwaiil, as well as by the absence of some of the summer 

 visitors. An esteemed correspondent, Mr. (^^iibert It. Lansin;,', of San Francisco, has 

 furnished a list of birds collected by him at Sacramento in March, 1873, which includes 

 the following species not in our enumeration of summer birds: — 



1. Chamasa fasciata. March 23. 



2. Ilesperiphona vespcrtina. March IG 



3. Junco oregonus. 



4. Corvus carnivorus. 



5. Cyanocitta californica. 

 0. Zouotrichia intermedia. 



7. Zonotrichia corouata. March 23. 



8. Melospiza guttata. March IG. 



Of the above, specimens were sent of Nos. 1, 2, 6, 7, and 8.
