Thanks for posting that link. It appears the bats I think we have - little brown bats (seriously) - will roost in caves, as well as trees and structures. I would think the caves likely to have a moderated temperature relative to the black painted bat boxes I've built so perhaps temperature is not the deciding variable.

Thanks again!
