While cutting some trees, I found some that were hollow. I set them back thinking I might use them. I later rebuilt a fence, and found a post that was hollow. Inside the post, I found left over bird nests. This gave me the idea. Use these as owl houses. I will show the way I built the small owl house. The large hollow logs are going to take a little more effort, but I think they will work. I'm not sure if owls will build, or some other critter may move in. Nevertheless, some creature should make use of the home.
Step 1: Materials
To build a recycled owl house, you have to find logs or posts that are hollow. The following is a list of items I used:
2 x 8 board ( I had some laying around)
1 x 4 board ( this should be about a foot longer than the cut post for mounting)
8-12, 3" wood screws
3' piece of all thread
4 nuts and washers to fit the all thread
