Do you every see these??/
I got a pump house that get new guests trying to get in every night,,,,... and it is nov....

Vinke,

We get a ton of calls where they all drop by on their way to "parts unknown."

It is the source of many calls that go like this.

"This morning I walked out in my shop (or barn) and there were 500-1000 bats on my ceiling that weren't there
yesterday!"

I've got a church that I excluded last spring and the migrating colonies of Mexican free-tailed bats are stopping over
under the eaves (not part of exclusion, just open space to night roost), so of course they are calling wondering why
this is happening.

These make good educational moments though as we know most just want them to move!

If bats could figure out a way to not leave urine streaks on stucco, I believe most folks would just keep throwing mouse
poison and bait out, as most of my clients first believe they have rodents, not bats.

The project we've been running this year that we started last spring looking at thermal dynamics of bat roosts for highway
bridges, has us watching our various species closely every week. About 4 weeks ago, nearly all of our myotis species (yuma
and little browns) bolted and left the bridge, while our free-tailed bats are still hanging in there, but they really cluster more
when the temps drop, makes for interesting data.

We have a few stubborn myotis that haven't left those spots yet within the bridge, but other than that, things are really dropping
fast.

One of our last to hibernate is the pallid bats, they can be active far more even during winter months here, but most are out and
around till very late october and even into november long after the aerial hawking bats have headed for caves and other countries.

Really enjoy bats and bat work because there is always something new to learn and even though there are great bat biologists and
researchers out there with decades of experience and work, so much is still unknown, compared to critters you can easily collar
and track, and those that have always been deemed more financially worth the research for our purposes.

What kind of bats are you seeing in the pump-house?

Justin

Not only are you west coast people crazy but now your bats have caught it!

I see the same thing in the spring. Since I go statewide on bats I can chart my calls and south Georgia always rings first and quite a few of those are here today gone tomorrow and almost always free tails.
