They seem to share a lot of characteristics with bats:
- Natural roosts are large, dead trees
- Natural roosts are disappearing or completely gone in many areas
- Cannot perch on a branch or the ground - must hang
- Eat tons of insects that bug humans
An interesting experiment would be to hang bat houses on a swift tower. I guess hanging a bat house on a chimney would be the same.
Anyway, just wondering if anyone has tried building one.
