Speaking of pilated woodpeckers we have them here also as well as smaller ones. There's another bird (nuthatch?) that's pretty small but pecks in a circle around the tree...like connect the dots.......
Correct me if I'm wrong but I thought if you just take, say, a pocket knife and cut around a healthy tree it can die since you're cutting the living growing part off all the way around.
I understand woodpeckers going after food insects in a diseased tree, but to me the pecking around a healthy tree would cause damage, even killing it.
Am I right?
Thanks...
Pileateds main diet is carpenter ants in dead or dying trees. In general they do not harm healthy trees.

Behavior and ecology
Male drilling for food
Pileated woodpeckers mainly eat insects, especially
carpenter ants and wood-boring beetle larvae. They also eat fruits, nuts, and berries, including
poison ivy berries.
[15] Pileated woodpeckers often chip out large and roughly rectangular holes in trees while searching out insects, especially ant colonies.
[12] They also lap up ants by reaching with their long tongues into crevices. They are self-assured on the vertical surfaces of large trees, but can seem awkward while feeding on small branches and vines. They may also forage on or near the ground, especially around fallen, dead trees, which can contain a variety of insect life. They may forage around the sides of human homes or even cars, and can be observed feeding at suet-type feeders. Although they are less likely feeder visitors than smaller woodpeckers, pileateds may regularly be attracted to them in areas experiencing harsh winter conditions.
Usually, pileated woodpeckers excavate their large nests in the cavities of dead trees. Woodpeckers make such large holes in dead trees that the holes can cause a small tree to break in half. The roost of a pileated woodpecker usually has multiple entrance holes. In April, the hole made by the male attracts a female for mating and raising their young. Once the brood is raised, the birds abandon the hole and do not use it the next year. When abandoned, these holes—made similarly by all woodpeckers—provide good homes in future years for many forest songbirds and a wide variety of other animals. Owls and tree-nesting ducks may largely rely on holes made by pileateds in which to lay their nests. Even mammals such as raccoons may use them. Other woodpeckers and smaller birds such as wrens may be attracted to pileated holes to feed on the insects found in them. Ecologically, the entire woodpecker family is important to the well being of many other bird species. The pileated woodpecker also nests in boxes about 4.6 m (15 ft) off the ground.
