INTRODUCTION 
The need for a publication of some kind embracing all possible information 
in regard to the avifauna of the islands off the coast of southern California first 
came to my attention in 1908. At that time I began compiling lists of the birds 
of each of the islands, for my own use only; but, at the suggestion of a few 
friends, I began four years ago to get these notes into shape for publication. This 
was undertaken, not because I have worked the islands more thoroughly than 
anyone else, which is not the case, but because of the special interest I have in the 
region. 
The present contribution was completed and delivered to the Editors in 
October, 1915, but for various reasons the Club has been long delayed in its pub- 
lication. During this delay, I have taken the opportunity of bringing the paper 
up to date, with the beginning of 1917. 
The territory covered in the present paper consists of the Santa Barbara 
Islands as properly restricted: Anacapa, Santa Cruz, Santa Rosa and San Mig- 
uel, with certain outlying rocks; the more southern group, popularly included 
under the same general term: Santa Barbara, San Nicolas, Santa Catalina, and 
San Clemente; and Los Coronados Islands. The last mentioned group does not 
lie off the coast of southern California, being Mexican territory and pertaining 
to Lower California, but is included in this report because of location nearby, 
and because of faunal similarity to the other islands named. 
TI regret that I have been unable to spend more time myself in field work— 
some weeks, at least, on each island. There seems no prospect of this in the near 
future, and further delay of publication for this reason seems unwise. As a 
matter of fact, there has been comparatively little work done upon these islands 
by anybody, and a visit of several weeks to any one of them is almost sure to add 
one or more new migrants or winter visitants to the list. 
The scope of this paper, as originally planned for my own use, has necessar- 
ily been amplified. I have endeavored to cite every publication relating to the 
island avifauna that could be deemed of importance, and to gather all unpub- 
lished notes relating to the subject, though I suppose it is useless to hope that I 
have uncovered every one of either. As a matter of general convenience, the 
nomenclature and order of the third edition of the American Ornithologists’ 
Union Check-List (1910) has been followed, except where modified by the one 
supplement since published. There are several island races belonging to groups 
which have lately been monographed, and which have been accorded standings 
different from those in the Check-List. In such eases, while I personally accept, 
for the most part, the opinions of the men who have done this work, Ff have in
