feet elevation in the mountains. Breeds principally in April. Incom- 

 plete set of 2 fresh eggs, taken March 14 ('96) by C. E. Groesbeck; set 

 3, incubation advanced, taken by myself June 5 ('95), both near Pa.sa- 

 dena. Sets are ordinarily of 3 to 5 eggs, but Evan Davis reports as 

 many as 8 in a set. 



134 — 375c. Bubo virginianus pacificus Cass. 



Pacific Horoed Owl. 

 Tolerably common resident in the mesa and foot-hill regions, but 

 becoming scarcer every year. Breeds in February and March. A. M. 

 Shields took a set of three fresh eggs in San Fernando valley, Feb. 15, 

 (■95). A. I. McCormick found a nest April 4 ('97), containing two 

 young just hatched and one addled egg. Full sets are of two or three, 

 usually the latter number. 



135 — jy8. Speotyto ciuiicularia hypogasa (Bonap.). 



BurrowiQg Owl. 

 Abundant resident on the lowlands and mesas. On the fields 

 around Bixby and South Clearwater, this bird is particularly numer- 

 ous. Nesting begins early in April. Latest set, 4 fresh, taken by me 

 near Pasadena, June 3 ('93). Sets 6 to 11, usually 9. 



136 — 3jg. Glaucidium gnoma Wagl. 



Pygmy Owl. 

 Quite a number of specimens have been taken in midwinter in the 

 mountains north of Pasadena. They undoubtedly breed in the higher 

 ranges, and are driven to lower altitudes by the winter storms. 



137 — j8^. Geococcyx calif ornianus (Less.). 



F^oad-runner. 

 Common resident of the brush and cactus-covered washes and 

 mesas, though scarcer now than formerly. Nests principally toward 

 the latter part of March, though I have taken fresh eggs in the vicinity 

 of Pasadena from March 12 ('92) until June 12 ('93). There is appar- 

 ently no such thing as a full set of Road-runners' eggs, as they are laid 

 at intervals of several days, and incubation begins with the first egg. 

 Thus I have found fresh and variously incubated eggs in the same nest 

 with good-sized young. The largest number of eggs I have ever found 

 in a nest at one time was seven. 



138 — sSya. Coccyzus avtericanus occidentalis Ridgw. 

 California Cuckoo- 

 Tolerably common summer resident in the willow regions of the 

 lowlands. This bird, shy and of secretive habits, I have found easily 

 overlooked. If carefully watched for, it will probably be found corn- 

 common where it is now seldom or not at all noticed. Breeds late. M. 

 L. Wicks, jr., took a set of four slightly incubated eggs, a few miles 

 east of Santa Monica, June 7, '89. 



139 — jgo. Ceryle alcyon (Linn.). 



Belted Kingfisher. 

 Occurs in considerable numbers during the migrations in suitable 

 localities from the coast to the foothills, and a few are found at all sea-
