BIRDS OF THE SOUTHERN CALIFORNIA ISLANDS 
With the above I have included all those birds which come to us after breed- 
ing, even though some of them reach us in the middle of the summer months. 
SUMMER VISITANTS 
Chordeiles acutipennis texensis 
Aeronautes melanoleucus 
Calypte costae

Of this list, I deem it extremely improbable that Chordeiles a. terensis is a 
Empidonax difficilis difficilis 
Icterus cucullatus nelsoni 
Hirundo erythrogastra 
regular breeder in the region; a few individuals of Aeronautes melanoleucus may 
possibly spend the winter.

whether it would not be better to label them ‘‘Casual”’.
