Breeds usually in April. A nest was found near Pasadena on March 

 25 ('97) > which contained young about two-thirds grown; this was un- 

 usually early. The latest set was of five fresh eggs taken by H. A. 

 Gaylord, May 25 ('95). This is undoubtedly the form to which our 

 Aphelocomez are referable, for they are not the same as the true A. cali- 

 fornica found further north. The habitat of A. c. obscura, which was 

 described from the San Pedro Martir Mountains, Lower California, 

 probably extends north, though less and less typically, as far as 

 Tehachapi. 

 179 — 486. Corvus corax sinuahis (Wagl.). 



American Raven. 

 Common resident in the lower parts of the County, principally in 

 the hill country. Frequently seen fljdng over the valleys from one 

 range of hills to another, but as a general thing very shy and not ven- 

 turing into settled regions. Lee Chambers took a set of three slightly 

 incubated eggs near Santa Monica, May 9, '96. 

 1§0 — 48'j. Corvus cryptoleucus Couch. 



White-QecKed Raven. 

 F. S. Daggett found the partly decomposed remains of one of these 

 birds under a tree in San Fernando Valley, April 18, '97. Possibly 

 the ravens which are common in that section are of this species. 



181 — 488. Corvus atnericanus Aud. 



flnjerican Crow. 

 Abundant resident in the lowlands. Breeds commonly in the 

 willow regions in April. Earliest set, of five fresh eggs, taken by M. 

 L- Wicks, Jr., near Santa Monica, April i ('93). Latest, of five consid- 

 erably incubated eggs taken in San Fernando Valley by R. Arnold, 

 May 17 ('94). Sets are of four or five eggs, mostly the latter number. 



182 — 491. Nucifraga columbiaiia (Wils.). 



Clarke's Nutcracker. 

 Common resident in the coniferous forests above 6000 feet. In 

 the vicinity of Mt. Waterman they are very numerous, and I secured 

 full-grown juveniles there in July C'97). 



183 — 4g2. Cyanocephalus cyanocephalus (Wied). 



PinoQ Jay. 

 Irregular visitant in the County, mostly in the higher mountains. 

 In the fall of '95, from Sept. i to 21, good-sized flocks were seen every 

 day or two in the vicinity of Pasadena flying northwest over the mesas 

 and along the foot-hills. A small flock alighted in some eucalyptus 

 trees in the heart of Pasadena, and remained several minutes before 

 continuing their flight. 



184—4^5)7. Xanlhocephalus xanlhocephaliis (Bonap.). 

 Yellow-headed Blackbird. 

 Occurs in large wandering flocks in the lowlands. The adult 

 males are usually seen in bands by themselves, not mixing with the 

 larger flocks which are made up of females and immature males. H. 

 S. Swarth found this species nesting in small numbers in the tule beds
