      HI EVERYONE-

      I found a Large-billed Savannah Sparrow at Caesar Chavez Park,
      West Berkeley during a waterbird survey (one of 72 over a 3 year period)
      in the winter of 2008.

      BHARATI MANDAPATI also observed the bird but I'm not sure she was duly
      impressed. No photos.

      THANKS, RICH

      All,

      Kerry Ross photographed the Abbotts Lagoon bird on 18 December. Photo on
      the WFO web site:

      There is at least one previous record of LARGE-BILLED SAVANNAH SPARROW from
      San Mateo County. A bird found at Princeton Marsh by Ron Thorn. Ron may
      be able to supply the date.

      The latest issue of BIRDING has an authoritative article on the status and
      identification of the Savannah Sparrow group by Jim Rising. It's a two-part
      article, "The Many Savannah Sparrows," in the Nov. 2010 issue.
