The past two evenings I’ve been walking Mystery in Heller Park. On occasion in the dusk sky I’d see creatures flitting around like bats, but couldn’t positively ID them as bats. They are pretty small. They are bats it’s just hard to even make out the silhouette against the sky to say, “Yep, that’s a bat.” I managed to go early enough where there was still enough light to ID them.

I got out my handy new Stoke’s Beginner’s Guide to Bats. It breaks them down by color code and there is a list for each state and which ones are common and which are uncommon. Based on the description. It looks like the are Evening Bats. I also heard a chirping noise which the book doesn’t describe them making. Since they only emit ultrasound I can’t hear that. Even the low end is still too high. I wonder if some other creature was making that noise? But the sound was coming from the general direction of the bats. I’ll see if I can take a picture with my new camera, but I don’t hold out much hope.
