ingly on the mesas and lowlands. I have taken specimens near Pasa- 

 dena on March 31 ('96), and April 17 ('97). In the fall H. S. Swarth 

 noted good-sized flocks in San Fernando Valley, Sept. 22, '97, and 

 took an immature male in Los Angeles, Sept. 5, '95. 



215 — 5(55. Spizella atrigularis (Cab.). 



Black-chinned Sparrow. 

 Common in .summer on brushy mountain sides. I have noted it 

 in the breeding season from the base of the foot-hills up to 7000 feet, 

 where the environment was suitable. In July ('97), I found this bird 

 numerous in the vicinity of Pine Flats, and secured full-grown juve- 

 niles, July 3. During the migrations this sparrow occurs sparingly on 

 the mesas along the foot-hills. The earliest spring record is that of a 

 specimen taken by H. S. Swarth at Cahuenga Valley April i ('96); the 

 latest in the fall, an immature male, taken by me near Pasadena, Sept. 

 10 ('97). 



216 — 56^. Junco hyemalis (Linn.). 



Slate-colored Juqco. 

 This bifd, usually considered as "accidental" in California, is ap- 

 parently of pretty regular occurrence in this vicinity, especially so as 

 compared with some other winter visitants which are expected to ap- 

 pear regularly. I took a female near Pa.sadena Nov. 14 ('96). H. S. 

 Swarth took a male at Los Angeles, Feb. 8 ('97). H. A. Gaylord took 

 a female at Pasadena, Feb. 27 ('97). F. S. Daggett took a male near 

 Pasadena, March 4 ('97), and saw at least seven others in a flock, 

 which had also been seen a week before in the same locality'. F. S. 

 Daggett took a male near Pasadena, March 15 ('93), from a flock of 

 fifteen, all apparently of the same species. 



217 — 56'ja. Junco hyemalis oregonus (Towns.). 



OregoQ JuQco. 

 A single specimen was taken by F. S. Daggett at Pasadena, Nov. 

 24, '96. This subspecies can at most be but a rare winter visitant. 



218 — 56JC. Junco hyemalis thurberi Anthon}'. 



Thurber's Junco. 

 Abundant in summer in the coniferous forests on the mountains. 

 In the winter there is a partial movement to lower elevations, and it 

 appears in small flocks down to the mesas and even further. In the 

 vicinity of Pasadena I have noted it as early as Oct. 3 ('94), and as 

 late as April 13 ('95). Breeds exclusively in the mountains, mainly 

 above 5000 feet. I noted fully fledged young in the mountains north 

 (if Pasadena on May 19 ('95). This is extremely early, as the usual 

 nesting time is the latter part of May. The latest set reported is of 5 

 slightly incubated eggs taken by R. Arnold on Mt. Wilson," June 12 

 ('92). Full sets consist of 3 to 5 eggs. 



219 — ^6g. Junco caniceps (Woodh.). 



Gray-t)eaded Juqco. 

 A single specimen, a female, was taken by W. B. Judson near Pas- 

 adena, Oct. 26, '94. This is our only record.
