March, iS<)S. Birds of the Pacific Slope of Los Angeles County. 31 



174 — 46Q.T. Empidonax griseus Brewst. 



Gray Flycatcher. 



Apparently to be found in some portion of our County throughout 

 the year. In fall, winter and spring it occurs in the vicinity of Pasa- 

 dena and El Monte in small numbers. Scarcely a dozen specimens 

 have been secured though they have been looked for with special 

 interest. The earliest specimen in the fall was taken by H. A. Gay- 

 lord in the San Gabriel River bottom near El Monte, Nov. 7 ('96), 

 and the latest in the spring, by me near Pasadena, May 4 ('97). Al- 

 though I have pretty well explored the mountainous parts of the 

 County, I have found the Gray Flycatcher in summer only in one 

 limited locality, on the slopes of Mt. Waterman (7500 to 8500 feet). 

 There, in July, this bird is not uncommon, though very shy, keeping 

 in the tallest pines on the mountain sides. I secured full-fledged j uve- 

 niles as early as July 11 ('97). Specimens of this species were iden- 

 tified by Wm. Brewster, its original describer, to whom I sent them 

 for determination. 



175 — 47 J^. Pyrocephalus rubineus mexicanus (Scl.). 

 Verroillion plycatcher. 

 Rare winter visitant in the lowlands. A female was taken by G. F. 

 Morcom in Los Angeles, Oct. 17, '95. H. A. Gaylord took specimens 

 at EI Monte, Oct. 17, '96 (immature male), Dec. 8, '95 (adult male) 

 and Feb. 8, '96 (adult female). Besides these specimens actuallj' taken, 

 others have been occasionally seen in winter in the San Gabriel River 

 bottom. 



176 — ^7^1?. Otocoris alpestris chrysolcema (Wagl. ). 

 Mexican liorned Larl^. 



Abundant resident over most of the lowlands and mesas. Espec- 

 ially numerous on the alkali pasture lands a few miles inland from the 

 coast. In fall and early winter, large flocks gather on newly planted 

 grain fields, and at that season do some damage. Begins breeding 

 early, and continues well into the summer. 1 have found nearly 

 fledged young the last week in March. I took sets of 3 and 4 fresh 

 eggs on April 17, '95, at Pasadena. G. F. Morcom took an incom- 

 plete set of -2 fresh eggs in the San Fernando Valley, June 5, '95. 



177 — 478a. Cyanocitta stelleri frontalis (Ridgw.). 



Blue-froQted Jay. 



Common resident of the coniferous regions in the mountains. 

 During severe winters this Jay appears in the foot-hills along with the 

 Belding's Jay, and sometimes even in the oak regions at lower eleva- 

 tions on the mesas. Breeds late. I took a set of 4, considerably incu- 

 bated, on June i, '95, and C. E. Groesbeck took a set of three fresh 

 eggs, on June 4, '96. Both were in the mountains a few miles north 

 of Pasadena. I secured an adult female of this species in perfect albino 

 plumage on Oct. 10, '96. 



178 — 4'iib. Aphelocoma califoniica obscura Anthony. 



Belding's Jay. 



Common resident of the scrub oak regions of the foot-hills a-id 

 mesas. I,ess common on the brushy mountain sides up to 6000 feet.
