There's a large birch snag in Paulik Park, which was intentionally left standing when the park was created from several large residential lots. It is falling apart, shedding bark, branches and heartwood. Yesterday it was falling apart a little more, and quite audibly.
Here is the reason, a Pileated Woodpecker working away. It is also one of the reasons the snag was retained. Next to a pond, nothing attracts birds like a good snag.
