94 . PACIFIC COAST AVIFAUNA No. 12 
Accidental on the islands. While on the Coronados, June 11, 1910, I (2) 
encountered two yellowthroats on a dry hillside. They were not at all wary and 
I had an excellent opportunity of observing them, but was at the time without a 
gun. When I recorded this I stated the opinion of another to the effect that they 
probably were not arizela, but I now feel no hesitation in referring them to that 
race. On San Clemente, in a canyon thickly overgrown with succulent vines, 
I clearly saw a male yellowthroat, March 23, 1915, as it flitted before me and be- 
came lost in the thick growth. It was probably this form.

Rather uncommon migrant. J. G. Cooper (1) recorded what was probably 
this subspecies from Catalina Island in October, 1863. On Santa Barbara Isl- 
and, May 14, 15 and 16, 1897, J. Grinnell and H. Gaylord (2) noted several 
each day in the weeds of a small ravine. Two males and three females were 
taken.

Common resident of San Clemente, Santa Catalina and Santa Cruz islands. 
Occurs also on Anacapa. On San Clemente, during 1903, G. F. Breninger (7) 
found this species breeding sparingly, about half a dozen pairs being on the isl-
