Today the bats are very active.  Some years we have a lot, others years less.  I haven't seen many this year, but there are several out tonight. Probably they are chasing insects roused by the rain.  I couldn't hear them, though, because the crickets and cicadas are making an almighty racket out there.

Illinois has 13 native bat species. While it's impossible to identify them whirring overhead, I suspect these are big brown bats because they are pretty large for insectivores.
