Briones Regional Park--Bear Creek Staging Area, Contra Costa, US-CA

Golden Gate Audubon Society Second Friday Birdwalk, 10 May 2013, meeting at the Bear Creek staging area of Briones Regional Park, and walking to the scout camp/Archery Range/ acorn woodpecker trees. Sylvia Hawley joined us (and left to meet Phila Rogers, who is convalescing from a broken shoulder- we all wish her a speedy recovery!). Bob Brandrieff attended, again. Sue Morgan from Tuesday for the Birds came, too.

Butterflies were pipevine swallowtail, tiger swallowtail, Lorquin's admiral (many), buckeye, Edith's chalcedon checkerspot, Sara's orange tip, alfalfa, and cabbage white.

We started with a bang: Lazuli Buntings in copulo ! (twice !) FOS Ash-throated flycatcher for me and several others. eBird shows this was the week that Ash-throateds arrived (May 3 thru today May 10), but few Chipping Sparrows have been seen yet (and none today, by us).
