PREFACE: 
Through the generosity of Mr. Hulett C. Merritt, and others of its mem¬ 
bers, the Pasadena Academy of Sciences was enabled to send a scientific exploring 
party to the southern Santa Barbara Islands during the past spring. 
The party consisted of Joseph Grinnell, who had the immediate charge of 
the expedition, and gave especial attention to the ornithology and entomology of 
the islands; Horace Gaylord, who collected mammals; and Harry Gaylord and 
James Brittan who devoted their time to archaeology. The party left San 
Pedro harbor May 11 in a large fishing schooner, fully equipped for the work 
previously mapped out, visiting the islands of Santa Barbara, San Nicolas and San 
Clemente in turn, making as complete investigation and collecting as many speci¬ 
mens as their time would permit. 
It is the intention of your Executive Committee to publish, under separate 
cover, reports on the birds and mammals observed and Secured by this party, and 
in accordance with this plan we append herewith the report of the ornithologist.
