I led the first of three bat walks last night. It went well, although the bat activity was a little low. It was about 20 degrees cooler than it has been lately, plus it was a little breezy so I think that is why there weren't many bats out. But we did see and hear a few. We did not see many birds (owls) which was a disappointment.
I put a Y connector from the bat detector output so I could record the bat detector as well as send it to a speaker for the group to hear. I'll see if I can post some snippets.
While we were walking along the detector picked up something on the ground, making a lot of loud ultrsonic noise. It was some kind of creature (probably insect) because it would stop when we were looking for it, then start again. But we never did see what it was, even though we picked through the grass pretty carefully. So it must have either been something really small, or something underground. Bizarre.
I asked everyone to leave their flashlights off which made it pretty neat to be out there with no lights. The trail is very flat so there is no tripping hazard. Last summer when I helped lead, the leader gave everyone a flashlight, which was a mistake. Every time we saw or heard something, all 25 people shined their flashlights on it causing it to immediately fly away. So I asked people not to use their flashlights.
