Where are all the bats?

I've had no bat rescues this summer. Aparently all the learner-flyers got their full licenses without my help, and the adults are being especially careful of cats, pools, and houses.

They're still around. At nights I can hear the metallic TING of the white-striped freetails and the ultrasonic jack-hammer-to-the-head of the wattled bats. I hope the drought hasn't knocked them around too much.
