tions a typical female as having been taken by C. P. Streator on Catalina in 
April, 1892, and I shot a specimen on Santa Cruz Island, April 27, 1911. These

Casual on the islands. H. Linton told G. Willett (ZS) that he had seen a 
robin on San Nicolas during the winter of 1912. While we were preparing 
breakfast on San Clemente, April 7, 1915, a single bird flew close above D. R. 
Dickey and myself, and lit on a rock a hundred yards away. By the time I had 
secured my gun it had disappeared. W. L. Dawson (7) noted a few on Santa 
Cruz Island during the first part of April, 1915.

another on the following day, on Santa Cruz.
