This may, perhaps, be explained by the fact that the former is not migratoiy, ''"""''''"'""'' "â¢"â '"^'"⢠but. resident even in the most northern part of its range ; while the Califor- nia one is also resident, and an inhabitant of oidy tlie southern portion of the coast region, not reaching nearly so .far north as the race of the interior.
