Nest Hole in Tree

This woodpecker hole in a dead tree looks like it should still be serviceable to nesting birds. Woodpeckers usually make a new hole each season, but other cavity nesters will readily take possession of an old hole.

The top of the tree has been lost. This doesn’t necessarily make the nest hole unusable.

Pileated Woodpeckers have been working on the back side of the tree. They’ve excavated quite a few large cavities in their search for food.

It looks like the back side of the woodpecker nest cavity has been compromised. I’ve never known a woodpecker to include a back door in its nest design.

This nest cavity may have been used more than once. The original layer of wood chips used as a base by the woodpecker is partially covered by a layer of shredded cedar bark. There’s probably not much chance of it being used again.
