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.
