BIRDS OF THE PACIFIC SLOPE OF SOUTHERN CALIFORNIA 



1. (1) iEchmophorus occidentalis (Lawrence). Western Grebe. 



Common winter visitant to the ocean and salt lagoons along- the coast. Occa- 

 sional on bodies of water inland. Arrives about September and leaves generally 

 by the latter part of April, but may be seen occasionally during the summer. 

 A single Western Grebe was noted by Bradford Torrey on the ocean near 

 Santa Barbara on several occasions during the months of June, July and 

 August, 1910 (Condor xn. 1910, 204). 



2. (2) Colymbus holboelli (Reinhardt). Holboell Grebe. 



Rare winter visitant. Observed at Santa Barbara by A. L. Heermann (Pac. 

 R. R. Rep. x, 1859, 76), and C. B. Nordhoff records finding the remains of an 

 immature bird at Elsinore Lake, Riverside County, in February, 1902 (Auk. 

 xix, 1902, 212). 



3. (3) Colymbus auritus Linnaeus. Horned Grebe. 



Probably a fairly common winter visitant on the ocean, less plentiful on 

 inland bodies of water. C. P. Streator took a specimen at Santa Barbara in 

 1885 (Orn. & Ool. xi, 1886, 90). I have taken specimens at Hyperion, Los 

 Angeles County, as follows: Adult female, March 10, 1911; adult male, Jan- 

 uary 3, 1912; and adult male, January 8, 1912. C. B. Linton took an immature 

 female at Alamitos, Los Angeles County, January 14, 1907, and an adult 

 female at San Diego Bay, November 4, 1906 (Condor ix, 1907, 110). E. 

 Heller took a specimen near Riverside in the winter of 1893 (Condor in, 

 1901, 100). 



4. (4) Colymbus nigricollis californicus (Heermann). Eared Grebe. 

 Common breeding bird on some of the lakes of higher altitudes, less common 



on ponds in the lower country, south to San Diego County. In winter may 

 be found plentifully on ponds of the lower country, on the salt lagoons along the 

 coast, and on the ocean. Breeds at Elizabeth Lake, northern Los Angeles County, 

 and abundantly at Bear Lake in the San Bernardino Mountains. At the latter 

 place I took fresh sets of eggs on June 22. 1907, at which date most of the nests 

 contained incomplete sets. 



According to Alphonse and Antonin Jay, a few pairs of these birds nest 

 every year at Railroad Lake, a small lagoon near Wilmington, Los Angeles 

 County, a short distance from the ocean. H. J. Lelande found a colony of 

 about fifteen pairs nesting at Nigger Slough, Los Angeles County, July 8, 1911. 

 All of the nests contained eggs at this date. 



A colony of more than a hundred birds was found by A. M. Ingersoll and 

 W. B. Judson at San Jacinto Lake, Riverside County, in 1897. On June 8, 

 they examined upwards of forty nests containing eggs. C. S. Sharp found a nest 

 of the Eared Grebe, containing seven partly incubated eggs, in the San Pasqual 

 Valley, near Escondido, San Diego County, April 22, 1906 (Condor ix. 1907, 85). 



5. (6) Podilymbus podiceps (Linnaeus). Pied-billed Grebe. 

 Common breeding species on fresh water ponds and lakes of the lower
