1917 BIRDS OF THE SOUTHERN CALIFORNIA ISLANDS 93 
Abundant winter visitant. Arrives in October and leaves in April. A. van 
Rossem (7) found this species very common on the Coronados the first week in 
April, 1909, and we noted it on San Clemente up to the same time in 1915. It 
was very numerous on Catalina during my several visits in April, especially so 
in 1911, while during December, 1897, J. Grinnell (10) says that it was even on 
the beaches, busily engaged in flycatching within a few feet of the surf. On 
Santa Cruz, A. van Rossem and I (8) found a few still present the last week in 
April, 1911.

ual may spend the winter. On San Clemente Island, C. B. Linton (3) shot a 
Townsend Warbler while it was flying along the beach, in December, 1908. H. 
Gaylord and J. Grinnell (7) each shot a female on Santa Barbara Island, May 
16, 1897, and Linton (2) secured a bird on Santa Cruz, December 13, 1907.
