 took a female on San Clemente, March 28, 1897, and two males on Catalina, De- 

 cember 24 and 28, respectively, of the same year. H. C. Oberholser (4) men- 

 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 

 are all the island specimens which I can locate.

Casual on the islands. H. Linton told G. Willett {MS) 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 {!) noted a few on Santa 

 Cruz Island during the first part of April, 1915.

Visits the islands in limited numbers during the winter months. Several 

 specimens were taken by C. B. Linton (i) on San C-lemente Island from January 

 to April, 1907, and W. L. Dawson (4) noted a single bird, April 5, 1915, and 

 another on the following day, on Santa Cruz.
