When I lived down near Vista, CA I used to note this westward migration
in early summer of all the species you mentioned plus some Scott's
Orioles. Also the late phainopeplas did nest over on the "west" side.
Another species that seemed to become more abundant at the same time was
the cactus wren, but whether this was due to actual movement to the west
or if they just became more obvious after nesting was never answered.
