GENERAL ACCOUNTS OF THE BIRDS 
i; Aechmophorus occidentalis (Lawrence) 
WESTERN GREBE 
Aechmophorus occidentalis (1) Howell and van Rossem, Condor, x11, 1911, p. 209. 
Probably a regular and not uncommon winter visitant. C. B. Linton (MS) 
has noted this species at different times during the winter months in the vicinity 
of San Clemente and Santa Barbara islands. A. van Rossem (7) noted a single 
bird at Santa Cruz Island the latter part of April, 1911. 
2. Colymbus auritus Linnaeus 
HorNnED GREBE 
Colymbus auritus (1) Dawson, Condor, xvit, 1915, p. 204. 
W. L. Dawson (1, WS) saw and photographed two of these birds at Prison- 
er’s Harbor, Santa Cruz Island, April 22,1915. He says that in the photographs 
the species is recognizable, as the birds were approaching high nuptial plumage. 
ae Colymbus nigricollis californicus (Heermann) 
EARED GREBE 
Colymbus nigricollis californicus (1) Grinnell, Pasadena Acad. Sci., 11, 1898, p. 5. 
Am[erican]. Eared Grebe (2) Grinnell, Bull. Cooper Orn. Club, 1, 1899, p. 19. 
Colymbus californicus (3) Linton, Condor, x, 1908, p. 82. (4) Linton, Condor, x, 1908, 
p. 125. 
Common in winter about all the islands. C. B. Linton (ZS) has found the 
species at San Nicolas in winter, and (3) recorded large flocks near the north 
end of San Clemente from December to March, 1907. He also reports (4) one 
specimen taken at Santa Cruz during November of the same year. During the 
latter half of April, 1911, A. van Rossem and I found the birds to be rather com- 
mon in the latter locality. One taken April 25 was in the midst of the spring 
molt. J. Grinnell (7) found them to be numerous at Catalina during the last 
week in December, 1897, and I have noted them there repeatedly throughout 
April. 
4. Podilymbus podiceps (Linnaeus) 
PIED-BILLED GREBE 
The only record of this species from the islands seems to be that of a female 
taken by H. Wright at San Clemente, August 26, 1908, and now in my collection. 
Dd: Gavia immer (Briinnich) 
Loon 
Gavia immer (1) Dawson, Condor, xvi, 1915, p. 208. 
While at Santa Cruz Island during April, 1915, W. L. Dawson (1) saw sey- 
eral of these birds at close range. This species undoubtedly oceurs about the isl-
