GENERAL ACCOUNTS OF THE BIRDS 



1. Aechmophorus occidentalis (Lawi-pnee) 



Western Grebe 



Aechmophorus occidentalis (1) Howell and van Rossem, Condor, xiii, 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 (1) noted a single 

 bird at Santa Cruz Island the latter part of April, 1911. 



2. Colymbus auritus Linnaeus 



Horned Grebe 



Colymhus auritus (J) Dawson, Condor, xvii, 1915, p. 204. 



W. L. Dawson (1, MS) 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. 



3. Colymbus nigjicoUis calif ornicus (Heermann) 



Eared Grebe 



Colymbus nigricollis calif ornicus (1) Grinnell, Pasadena Acad. Sci., ii, 1898, p. 5. 

 Am[erican]. Eared Grebe (2) Grinnell, Bull. Cooper Orn. Club, i, 1899, p. 19. 

 Colymbus californicus (3) Linton, Condor, x, 1908, p. 82. (Jt) Linton, Condor, x, 1908, 

 p. 125. 



Common in winter about all the islands. C. B. Ijinton {MS) 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 (1) 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. 



5. Gavia immer (Briinnich) 



Loon 



Gavia immer (1) Dawson, Condor, xvii, 1915, p. 203. 



While at Santa Cruz Island during April, 1915, W. L. Dawson (i) saw sev- 

 eral of these birds at close range. This species undoubtedly occurs about the isl-
