Bill Chen found and photographed a FIELD SPARROW this evening at Gomes Park in Fremont, a small park due east of Lake Elizabeth in Fremont. This may be a first county record for Alameda. (I see no previous eBird records, but i didn't do any other research.) His excellent photos were posted to the Fremont Birding Circle group on Facebook a short time ago:
