Got them up on solid, old utility poles; going to add raccoon guards next trip out. Barred owl house is insulated. The other is a Great Crested Flycatcher house. Not a common bird here but had one nest in a screech owl house a few years ago, and I wanted to offer appropriate housing.
They look really great @Jesse. Good luck with attracting birds. Hopefully they will fill up and be used. @cathyb I think it would be fun to have a bat house too. I see bats in summer around my house so they have to be roosting around here somewhere.
OMG @David That’s a real throwback pic.
You’re right, a bat house doesn’t really need to be that fancy, unless the Joker or any of those types is lurking somewhere nearby.
