Today I listened to a radio program about bats. There was lots of information, such as some bats are pollinators, and some eat their body weight in insects, such as mosquitos, every night. What they didn't say was how to attract or support bat populations. Apparently, some are in decline (like most things in nature). I looked at various articles, and most had nothing I could do - like keep old dead trees standing as nesting places, and keeping wetlands growing with lots of cottonwoods. Batboxes seem expensive. They need to be installed at least 12 feet above the ground. I might be able to do that ONCE. However, the article I read said they should not be installed on trees, because cats and raccoons can climb and eat them. My neighborhood has a lot of feral cats, and some racoons. I don't know that there is anything I can do. Any experiences to share? Thanks for reading. This reminds me of when I read about barn owls. I put up a nesting box ten years ago, It's never been used by barn owls!
