[EBB Sightings] ID question at Hayward Shoreline

Can anyone help me with an indentification?  I'm
stumped with the sparrow shown in the first two
pictures of this slide show of pictures from Hayward
Regional Shoreline.

I keep trying to make it fit grasshopper sparrow, or
female house sparrow, or female blue grosbeak... but
nothing quite fits.

Last weekend, I found these sparrows in the sage brush
along the flood control channel between the Winton Ave
parking lot and Hayward's landing.   The rest of the
pictures are of the shorebirds and raptors in the
marshes north of Winton Ave. (aka "Frank's Dump").
Sightings included:

Savannah Sparrow
Chestnut-backed Chickadee

Thanks for your help -

P.S.  It's not exactly Alameda county, but you are
welcome to checkout my pictures from my trip to
Florida in August.  Yes, you can see birds there
off-season.
