A Pileated Woodpecker, taking full advantage of the new suet block. At one point he sticks a bit on the frame, then takes it off. He drops a little, and looks down to see if it's worth going after. Nope, it's not, back to work. The raspy hollering in the back is a Stellar's Jay being about as melodic as they ever get, and the hammering is a neighbour.
