No they don't. They peck the holes looking for bugs to eat. They chip away sections of the bark and tree hunting for insects that live in the tree.

It contains a description of how and why woodpeckers drill the holes.
Pileated Woodpeckers live in The Temperate Forest
The pileated woodpecker, Dryocopus Pileatus, nests in cavities in trees it digs out with its chisel like beak.
No, the wood has to be already diseased or insect infested for them to even have anything to do with it.
The pileated woodpecker usually escavates several nest holes. They will roost in these holes, and nest in another close by.
No. Pileateds are permanent residents throughout their range.
Woodpeckers are looking for food. They are looking for insects in the bark/tree.
Trees provide food, shelter and a nest site for Woodpeckers.
Various kinds of woodpeckers tap on trees. They do it to advertise their presence, claim territory, excavate cavities to nest in and to obtain or store food.
The more oak trees there are means that there will be more squirrels living in the park because they use the holes in the trees to store food for the winter.
They make holes so they can store their food during the migration time and come back and be able to have food without "hunting" for food. Also so after the migration time they can come back and continue or if they made a big enough hole before the migration they can have a home and will not have to "search" for a empty hole in a tree to live in.
No, they peck wood/trees looking for insects.
It makes holes so that it can use its barbed tongue to grab bugs inside the tree.
All species of woodpeckers have strong beaks. They also have a head structure that enables them to constantly and very rapidly to bash their beak into wood in search of grubs - without damage to their brain!

Pecking wood is how woodpeckers extract food from trees. Though that is the primary purpose, they also use drumming and hammering of their bills for breeding rituals and communicating.
