I joined the Audubon Morning Birdsong Walk at Pittock Mansion Friday morning. The cold damp weather kept most birds hunkered down out of sight, but this Red-breasted Sapsucker put on a nice show. He would fly to the concrete light posts and drum on the metal light fixtures to declare his territory. Several woodpecker species, flickers in particular, are known to drum on metal.
