Bats are often associated with Halloween and relegated to roles in scary movies, but they are so much more. Bats are very diverse and fascinating creatures that play an invaluable role in our ecosystem. I love the fact that more people seem to be recognizing this and wanting to do things like put up bat houses and make their yards more bat friendly.
In this episode, I talk with Reed Crawford. Reed is a PhD student in Ecology, Evolution, and Conservation Biology at the University of Illinois at Urbana-Champaign. He is studying bats and how they thermoregulate. His research has lots of implications for how we can make our bat houses safer for and more attractive to bats.
Reed and I start out talking about some of the common myths we hear about bats and the many threats that bats face. We then move on to discuss how bats need roosting spots with different conditions depending on factors like the time of year and the reproductive stage of the bat. The temperature of the site throughout the day and night is one of those important conditions, especially for moms and their young (pups).
Unfortunately, sometimes our bat houses can provide nice, warm, attractive conditions for mother bats to raise their young, but on our really warm summer days can get too hot and potentially kill the bats. Part of Reed’s research is looking at different modifications we can make to bat houses to make them safer for the bats. We talk about many of those modifications including a different style of bat house called a rocket box, that doesn’t look like the flat boxes that are commonly sold as bat houses.
In addition to Reed’s research, we talked about suggestions for putting up a bat house and improving the bat habitat around our homes. One of the questions Reed and I both commonly get in regards to bat houses, is “Why aren’t bats using the bat house that I put up?” Unfortunately, there isn’t a simple answer to that question. It often depends on a number of different factors. But, hopefully Reed’s research and those of others pursuing similar questions, will help us give more solid answers to that question in the future.

Backyard Ecology: Creating Space for Pollinators and Wildlife
Nature isn’t just “out there.” It’s all around us, including right outside our doors. Hi, my name is Shannon Trimboli, and I am the host of Backyard Ecology. I live in southcentral Kentucky and am a wildlife biologist, educator, author, beekeeper, and owner of a nursery specializing in plants for pollinators and wildlife conservation. I started Backyard Ecology as a way to share my love of exploring nature and learning about different plants and animals. I invite you to join me as we ignite our curiosity and natural wonder, explore our yards and communities, and improve our local pollinator and wildlife habitat.
