1917 BIRDS OF THE SOUTHERN CALIFORNIA ISLANDS 43 
there April 10, 1915. J. Grinnell (3) found it very numerous at Catalina dur- 
ing December, 1897, and I have noted it in abundance there throughout April. I 
have also seen a few near Santa Barbara Island the first of May. C. B. Linton 
(4) found adults and immatures tobe common at Santa Cruz Island, November 
and December, 1907, and A. van Rossem and | saw them from time to time in the 
same locality during the latter part of April, 1911. G. Willett (6) recorded them 
as common at San Miguel Island, the middle of June, 1910, and C. P. Streator 
(1) stated that he saw immature birds there and was under the impression that 
they bred in the locality, which supposition is, of course, extremely unlikely. 
Willet (7) also saw a male at Santa Rosa Island, June 8, 1910. All of our sco- 
ters prefer the ocean in the vicinity of sandy beaches, and so are not nearly as 
common at the islands as they are along the neighboring mainland.

Chen hyperboreus hyperboreus (1) Dawson, Condor, xvii, 1915, p. 204. 
While on Santa Cruz Island in April, 1915, W. L. Dawson (7) saw a pair 
of these birds that were kept in captivity at the ranch house. They were winged, 
of course, and had been taken from flocks numbering several thousand which 
visited the island during the winter of 1914. 
49. Anser albifrons gambeli Hartlaub 
WHITE-FRONTED GOOSE 
Anser gambeli (1) Linton, Condor, x, 1908, p. 126. 
C. B. Linton (7) found this goose abundant on Santa Rosa Island in Novem- 
ber, 1907, and he (MS) informs me that the fishermen at Santa Cruz Island are 
in the habit of running over to Santa Rosa to get them for Christmas. I have 
been told by several fishermen that a goose, probably this one, is found on Ana- 
capa in flocks during part of the winter.

Fairly common about all of the islands but evidently breeding on only a few 
of them. I have seen these birds all through the spring and early summer stand- 
ing on the kelp beds in the vicinity of the Coronados. 
From San Clemente, H. C. Oberholser (177) has described a subspecies, the
