Ash tree and pileated woodpeckers
My neighbor has an ash tree which she's having treated for ash borer. The woodpeckers have made numerous holes in the tree trunk's bark, and now a swatch of bark is gone, adjacent to the holes, about 4' long and 3-4 inches wide at the widest part. Could the birds have loosened the bark? It looks as though the tree is shedding its bark.
