Bill's niece Sarah created a BirdWalker shop at Etsy. We've got a great set of postcards for sale there, please take a look!
Birding photos and trip reports by Bill Walker and Mary Wisnewski, California birders based in Santa Clara County. We've been collecting our trip reports since 1996.
Some of our favorite places to go birding include Charleston Slough and the Duck Pond in Palo Alto, Sacramento National Wildlife Refuge, and the Rio Grande Valley in Texas.
You can also see these sightings at Bill's eBird profile.
