not sure of ID, had thought maybe it was a female Red-winged Blackbird but the breast markings are not striped enough...
Savannah looks most likely to me, which undoubtdlymeans its a Song, or someother species entirely.
2-4 seen on lawn area.
San Benito savannah sparrow, Passerculus sandwichensis sanctorum
San Diego County, California, US
I think this is Lincoln's, but I'm not certain...
