Front cover photo by © Tom Greer of Sacramento, California: Yellow-billed Magpie (Pica nuttalli), Florin area, Sacramento County, California, 10 July 2003. Analyzed by habitat, the results of surveys in 2007 and 2008 imply a population of about 400,000 birds and substantial retraction of the range in the San Joaquin Valley.

Back cover: “Featured Photo” by © Vic Murayama of Chula Vista, California: Mangrove Yellow Warbler (Setophaga petechia, possibly of subspecies castaneiceps), near the mouth of the San Diego River, San Diego County, California, 13 January 2009, representing the second record of the Mangrove Warbler for California and third for the western United States of these subspecies normally restricted to mangroves along tropical coasts north to Baja California Sur and Sonora. The entirely chestnut head and a single generation of feathers in the wings indicate a definitive-plumaged male.
