Learn about the only mammals that can truly fly: what they eat, how they find their food, and where and when they sleep. Then build a bat house to provide them with a place to live!
The Challenging Part
The most challenging requirement of this honor is probably this:
16. Build or purchase a bat box, know the best place to put it and install it at a home, church, or your school. Record for 3 months what kind and how many bats have made it their home.
