Regional Differences

The three subspecies of Pacific-slope Flycatcher differ very slightly. A brightly colored subspecies (insulicola) breeds only on the Channel Islands in California; it has a different song and might some day be considered a separate species. Another, paler subspecies (cineritius) inhabits the mountains of southern Baja California, Mexico.
