Bats, man!

When I think of bats, I think of Louisville Sluggers, but there is the other kind, the flying kind that eats mosquitoes and menaces the general public.

And then I have to tell you about a friend who had a bat problem (as opposed to a Ratt problem) in her attic a few years ago, and called a licensed exterminator, who told her that the bats "must be laying eggs in the attic."

Egg-laying mammals, in the land of the free!

Bats don't reproduce that way, and you'd think they would have mentioned that during the extensive afternoon-long training that man received.  But meanwhile, down Texas way...

A large bunch of bats - a "swarm" in Bat-talk - caused a ripple on the weather radar as they flew away from a thunderstorm.

Chris Suchan, meteorologist for WOAI-TV in San Antonio, reported that a batswarm flew out of Frio Bat Cave in Uvalde County not long ago.

There were millions of them, Mexican free-tailed bats! And they got to be on live TV on May 20, and the radar footage shows the millions of encountering a thunderstorm.

A powerful mighty wind - a gust front, in weather parlance, caused by heavy rain pushing pushing downdrafts out of the way - collided with the bat brigade, sending them toward Utopia, Sabinal, and points east.

"Dual-Pol radar works beautifully to distinguish these bats from rain when storms and the bats are on radar," Suchan told his audience.

"[It's] easy to identify the ring signature, but on occasion, when they're starting to come out, it can look like a storm core until you see the ring show itself as they fan out."

If you can't tell a storm core from a ring show, Chris Suchan is there to help you, in case you don't mind living near some literal hellhole called the Frio Bat Cave, which bills itself as the second-largest bat colony in the world.

I don't even want to know what is the first.
