Bat and Owl houses

[Holladay]

Has any one ever tried to attract them?

My Dad made a Bat house and I tried for a few years...no go.

I live out in the country and I do have bats and owls around. I thought it would be fun to have a house around the place so I can watch them better.

I know placement is important, from what I have read. Both ~12' up and be on a pole.

Bats facing s/se for the sun, open area with no branches.

Owls can be in a tree, I guess. Open area next to a field.

That is about all I got...
