One of the things we saw on our trip to the Big Woods in AR was some unusual scaling of tree bark. This was patches of bark peeled off by chiseling sideways rather than digging straight in, and the work done on trees that are declining but still alive. In one case this was done in a swath several feet wide completely girdling a tree. Yes, yes theres a picture, still in the film camera. Doing more reading online it appears that this is exactly the sort of sign that has been seen in the area that is believed by many to be attributable to the Ivorybills. We may well have actually laid our hands on wood that the Phantom him/herself had touched... wow.
