Black backed wood pecker (Picoides arcticus), Lake Tahoe, California
No photo. It came to it's recorded call and was a sharply-marked male, with solid dark back and a distinct white jugal line. The habitat was an open ponderosa pine stand with a grass understory (pinegrass). The forest also had mature larches as a sub-dominant tree. Sapling grandfir and dougfir indicated the next succession. The Whitman National Forest has marked spaces in the area as "old growth" and "Managed for Woodpeckers".
Cruddy pics, but you can see the yellow forehead.
