not record it from northern California north of Shasta County. 

 Miss Kellogg in "Mammals and Birds of Northern California" 

 (University of California Publications in Zoology, Vol. 12, 

 1916), mentions it as having been taken only twice in the sum- 

 mer time by the Alexander expedition. On the other hand, we 

 found it more or less common at nearly every station where 

 we collected, at some places associated with Cassin's Finch. 



The song sparrow of this region, so far as we could make 

 out, is the Modoc Song Sparrow. This race appears to be a 

 comparatively recent one, and not so well established as many 

 others. This is shown in the wide variation of its markings, 

 some specimens being practically without black centers to the 

 dorsal feathers, while others have this black well developed. 

 This species was common about Weed but did not appear to be 

 especially numerous. 



We found the Wright's Flycatcher quite common where the 

 firs and yellow pines were of fair size and more scattered. They 

 appeared to have just come into the region. No other Empi- 

 donax was recorded at Weed. 



The Sacramento Towhee was fairly common in the vicinity 

 of Weed, but the Northern Brown Towhee was extremely rare. 

 While I was fairly sure of having caught a glimpse of one at 

 Weed, the identification was not sufficiently positive to record 

 it. However, as it is found only a few miles away and at but 

 little lower elevation, the chances are that my guess was correct. 



For some reason the Western Warbling Vireo seems to have 

 been scarce during the visits of the Townsend and Merriam 

 field parties, but we found it common enough this season, hav- 

 ing met with it at each of our stations, except one in the heart 

 of the coniferous forest. Miss Kellogg records it from three 

 stations only. 



While we found Audubon's Warbler, Black-throated Gray 

 Warbler, Macgillivray's Warbler, and the Golden Pileolated 

 Warbler more or less common in suitable places in this vicinity, 

 we had no direct evidence of their nesting here, yet there was 

 good reason to suppose that they would do so, or at least not 

 far away. 



The region immediately around Weed, at the altitude of 

 3000 to 3500 feet, has approximately the same forms of bird
