234 — 597a. Guiraca ccerulea eurhyncha Coues. 



Western Blue Grosbeak. 

 Tolerably common in summer; found mainly in the mesa regions, 

 and very local even there. Earliest seen near Pasadena, April 25 

 ('96). Extreme nesting dates: Set four, slightly incubated, taken by 

 M. L. Wicks, Jr., near I,os Angeles, May 18 ('89); and set four, 

 slightly incubated, taken by H. Robertson near I^os Angeles, June 

 24 ('93 ) • 

 235 — 599- Passeriyia ainoena (Say). 



Lazuli Bunting. 

 Common summer resident of the foot-hills and mesas. Extreme 

 dates of arrival and departure according to my notes are respectively, 

 April 4 ('96), and Sept. 17 ('97). This species becomes very scarce 

 after July, and I have only two records for September, including the 

 one quoted above and an earlier. Broods mainly in the latter part of 

 May. Extremes: Set three fresh taken by E. D. Parker near Pasa- 

 dena, April 30 ('95); and a slightly incubated set taken by A. I. Mc- 

 Cormick near Los Angeles, June 23 ('95). Full sets are of two to 

 five, in only one instance of the latter number, usually of four eggs. 



23ti — doy. Calamospisa melaiiocorys Stejn. 



Lark Bunting. 



Casual visitant. An adult male was taken by Ed. Simmons at 

 Newhall, May 3, '97, and two others were seen. 

 287 — 6oy. Piranga ludoviciana (Wils.). 



Louisiana Tanager. 



Common summer resident of the mountain canons and coniferous 

 forests from 1500 to 7000 feet altitude. Extreme dates of arrival and 

 departure are respectively, April 19 ('96) and Sept. 30 ('95). During 

 the spring migrations, in the larter part of April and early May, tan- 

 agers occur numerously on the mesas and lowlands, feeding on fruit 

 and berries. Breeds ordinarily about the first week in June. Ex- 

 tremes: Set three, fresh, taken by R. Arnold, May 5 ('95); and set 

 three, slightly incubated, taken by Ed. Simmons, June 30 ('95); both 

 in the canons north of Pasadena. Sets are of three or four, and in one 

 case, noted by R. Arnold, of five eggs. 

 238 — 6iia. Progne subis hesperia Brewst. 



Western Martin. 



Common in summer mostly in the mountains where they nest in 

 holes in the tall dead firs. Frequently seen flying over the mesas in 

 spring and late summer. A few breed in the oak districts to the west 

 of San Fernando Valley. R. Arnold has found them nest-building 

 there by April i. As yet no eggs of this bird have been taken in the 

 County. 



239 — 612. Petrochelidon lunifrons (Say). 



Cliff Swallow. 



Abundant in summer in the lower portion of the County. Earliest 

 arrival in the spring, noted at Pasadena by H. A. Gaylord, March 8 

 ('96); latest in the fall, seen by me at Long Beach, Sept. 7 ('95).
