Tried again to get Bats in flight at the guzzler. This year the guzzler was full of water all summer. Partly because there was a major flash flood that almost wiped the whole place out. However, I got very few triggers from the Infra-red sensor set up this year. Not as many bats this year and they seemed to be coming in much higher, possibly because a mound of dirt at the end of the guzzler that changed the flight pattern. So eventually turned the infra-red off and did this by timing with the cable release plugged in. Didn't get a lot of shots, but managed a few nice ones.
