Red Car Canyon: Northern Flicker In Dead Eucalyptus Tree

Photo: Diane Edwardson, December 9, 2015.  While walking through Red Car Canyon, I heard a bird singing a tune I didn't recognize.  It was the only bird in the canyon who did not seem to care about the Great Horned Owl sitting in a pine tree, 50' away.  Unfortunately, this was the best shot I could get of the Northern Flicker, a large species of woodpecker.  (Click on photos to enlarge.)
