During two trips to the San Francisco Bay Area I found two great places to spot the lively Acorn Woodpecker. The first good spot is at Stanford University at the Main Quad in front of the Stanford Memorial Church. There the Acorn Woodpeckers live in the tall palm trees. The second spot that you can usually spot them is at the Bear Valley Visitor Center in Point Reyes. Just off to the right of the parking lot in front of the visitor center is a nature trail where you can hike up to see the Miwok Village. The Acorn Woodpeckers are often in the trees and fences of this area. There are additional trails to bird at this location including a very long trail all the way to the ocean.
