A classic Gouldii Song Sparrow. Obvious Heermanni group. Not Cleoensis of the north by face color. Faint yellowish mash on upper back used to seperate from Heermanni subspecies, but those wouldn't come up here anyways
Another good example of Gouldii. I have attached two photos. First one shows all characteristics of the coastal California 'Herrmanii Grouo" In the second photo looks at the back of the neck better and shows classic Gouldii Charecterisitcs. Even though Herrmannii subpsieces don't get up close to Marin
