March, 1898. Birds of the Pacific Slope of Los Avgetes County. 29 



took juveniles near Mt. Waterman on July 14, '97. A few have been 

 taken in April and early May, evidently in migration, on the lowlands 

 and mesas, usually near the base of the mountains. 



163 — 4.^4.. Tyrannus tyrajinus (Linn.). 



Kit^gblrd. 

 Only one record: An immature male taken by W. B. Judson at 

 Santa Monica, Aug. 31, '95. 



164 — 44.J. Tyrannus verticalis Say. 



Arkansas Kiogbird. 

 Abundant in summer throughout the lowlands and mesas. My 

 earliest and latest records are, respectively, March 17 ('96) and Sept. 

 14 ('97)- Breeds mainly toward the last of May, in the vicinity of 

 ranches and along country roads. Earliest set, of three fresh eggs, 

 taken May 7 ('93), by H. A. Gaylord in San Fernando Valley. 

 Latest set, of three eggs, incubation about one-half, taken by me June 

 28 ('92) near Pasadena. Full sets in this vicinity consist of three to 

 seven eggs, usually four or five. 



165 — i).ij.8. Tyrantius vociferans Swains. 



Cassin's KiQQbird. 

 Common in winter in the lower parts of the county. I have noted 

 it in the vicinity of Pasadena from Sept. 16 ('95) until May i ('97). 

 A few remain through the summer and probably breed in the western 

 part of the county. H. Robertson saw a pair west of Los Angeles, 

 June 9 ('97), which he has no doubt had a nest near by. I found sev- 

 eral nests containing young in July ('93) in Simi Valley, just over the 

 line in Ventura Countv, and I saw adults on this side at Chatsworth 

 Park.

Ash-throated Flycatcher. 

 Common summer resident from the oak regions of the lowlands 

 up to 6000 feet in the mountains. Earliest arrival in the spring noted 

 by H. A. Giylord, April 4 ('96); and I have seen a very few as late as 

 September, the last, Sept. 14 ('95). Breeds most commonly in the 

 last week of May. Extremes: Set five fresti, taken by W. B. Judson, 

 May 16 ('97) in the West Fork, north of Mt. Wilson; and a set of four 

 fresh eggs, taken in the same locality by H. Leland, June 8 ('96). 



167 — 4.57. Sayornis saya i^QWAi^.').

 H('95)-

 especially about barns and stockyards. Eggs usually laid toward the 

 last of April. Extremes: Set four, slightly incubated, taken by C. E.
