Last night, right after sunset, my housemate Anita was gazing out the windows of our Austin house. She turned to me and said, “Hey, I see swallows coming out of our chimney.”
“It’s not swallow time,” I replied. “It’s BAT time.” I then briskly went out to see what was going on at the ole chimney.
Sure enough, two sturdy-looking bats emerged from the flashing around the chimney…right where we’d been noticing “mouse turds” for a couple of weeks. I immediately googled “bat guano–images.” Yep, that’s it, all right.

Anita then mentioned that the next-door folks had just erected some kind of wire barrier all around their chimney. Hmm. Maybe the bats just moved one house down.
