Th) Aechmophorus occidentalis (Lawrence) 
WESTERN GREBE 
Synonyms—Podiceps occidentalis; Podiceps  clarku; Aechmophorus 
clarkii; Aechmophorus occidentalis clarkvi; Clark Grebe. 
Status—Common during fall, winter, and spring along the seacoast, on the 
bays, and on the larger bodies of water inland throughout the state. Remains 
through the summer on Buena Vista and Tulare lakes, where it may breed, as 
it does certainly on Eagle Lake and Tule Lake in the northeastern part of the 
state (Townsend, Proc. U. S. Nat. Mus., x, 1887, p. 190; Sheldon, Condor, rx, 
1907, p. 186; V. Bailey, Condor, tv, 1902, p. 64). According to Belding (MS), 
the species formerly bred in Sutter County and in the vicinity of Stockton, be- 
fore so much of the tule land was reclaimed. Noted casually through the sum- 
mer on the ocean'near Santa Barbara (Torrey, Condor, xt, 1910, p. 204), and 
on salt sloughs near San Diego (Belding, MS). 
2 (2) Colymbus holboelli (Reinhardt) 
HOLBOELL GREBE 
Synonyms—Podicipes holboelli; Podiceps coopert; Podiceps cristatus; 
Crested Grebe; Red-necked Grebe. 
Status—Fairly common as a midwinter visitant along the seacoast. Beck 
(Condor, rx, 1907, p. 58) found it of regular occurrence in small numbers on 
Monterey Bay from November to February; also, as observed more recently, 
remaining until May (Proce. Calif. Acad. Sci., 4th ser., m, 1910, p. 58). Other 
record stations are: San Francisco Bay—Presidio and Oakland (Kobbe, Auk, 
xvii, 1901, p. 270) ; Pacific Grove (Loomis, Proe. Calif. Acad. Sci., 2nd ser., v1, 
1896, p. 14) ; Santa Barbara (Heermann, Pac. R. R. Rep., x, 1859, p. 76) ; Elsi- 
nore Lake (Nordhoff, Auk, x1x, 1902, p. 212) ; Lake Tahoe, September 6 (Beld- 
ing, MS). 
3 (3) Colymbus auritus Linnaeus

casually inland. Recorded from: Humboldt Bay (Townsend, Proe. U. 8. Nat. 
Mus., x, 1887, p. 190) ; San Francisco Bay (Kobbe, Bailey’s Handbook Bads., 
1902, p. xtvi); Monterey Bay (Loomis, Proe. Calif. Acad. Sci., 2nd ser., v1, 
1896, p. 14) ; Los Baftos, Merced County (Mus. Vert. Zool.); Santa Barbara

ton, Condor, 1x, 1907, p. 110) ; Lake Tahoe, September (Belding, MS) ; Hype-
