Falco richardsoni in Southern California

In a list of birds noted at the Annual Outing Meeting of the Southern Division of the Cooper Ornithological Club which was held in the San Fernando Valley, Los Angeles CO., Cal., October 31st to November 2nd 1903 (see CONDOR, vol. VI, No. 1, page 22), I noted the taking of a specimen, October 3Ist, of Falco columbarius. At the time Mr. Grinnell called attention to its light color,and other members thought it might prove to be Falco richardsoni, but several hawks taken heretofore in the same locality were all typical Falco columbarius, and there being no richardsoni in southern California collections for comparison, it was, for the time being labeled columbarius. Through the kindness of Dr. Dearborn, the skin has recently been compared with the Field Columbian Museum series under his care, and at once pronounced Falco richardsoni. It is evidently a bird of the year in fresh fall plumage, with the light colored tail bands somewhat narrower than in the adult. The only previous California record (see Grinnell’s Check List of California Birds, page 33.) is that of Henshaw who records a specimen secured at Walker Basin, August 28, 1875.
