I just heard the loud, resonant call of a pileated woodpecker at my house and was able to locate it near the top of a redwood tree on Heartwood. It just flew south toward Shepard Canyon so if you live nearby open your windows and listen a bit.
A new yard bird for me, although it's the third one I've seen in northern CA.
