I have made some bird houses out of PVC trim boards they sell. The idea was no painting, no rot, and easy to clean out.
However the local squirrel didn't get the message about these being a long term use item thus lowering the cost of materials over time.
No idea why but this winter the squirrel decided to taste the PVC and found a nice place to chew, right at the entrance. Maybe it thought there would be something worth while inside to eat or thinking it could fit inside to stay warm???
In this next image you can see the nesting materials and the cavity where the actual birds reside. This is a wren nest so the hole is only 1-1/8" and the cavity is as far from the opening as possible. Trying to keep safe from prying paws and beaks of other birds that few inches isn't much....
It is nice to see that they, the wrens still have not gotten into putting bits of scrap plastic in their nests. They do like to bring in spider webs which seems odd to me???
I didn't feel like setting up a router for the cross hatching so I just went with a plain front. I can change that later if I want.
