PechaKucha with Batman

PechaKucha [ or ペチャクチャ translated as “chit-chat”] is a series of 6-minute talks from presenters in the creative industry including artists, musicians, architects, filmmakers, writers, entrepreneurs, and local personalities. Each presenter showed 20 images, each lasting for just 20 seconds. PechaKucha events foster the art of concise presentations.  This year’s PechaKucha Night Austin #32 was held in Austin on October 11, 2018. Merlin was honored to be invited by Austinites DJ Stout and Lana McGilvray, the hosts of PK ATX.
The following ten speakers each had 6 minutes to promote a subject in their area of expertise. Merlin, of course, promoted bats with emphasis on those in Austin and had an outstanding response. Watch his presentation!

Counting Free-tailed Bats in Bridges

9/10/18
By Merlin Tuttle

Merlin inspects Brazilian free-tailed bats (Tadarida brasiliensis) moments after removing them from their bridge crevice roost for counting.

For many years we’ve wondered just how many Brazilian free-tailed bats (Tadarida brasiliensis) could cram into a single 18-inch-deep bridge crevice. Accurate counts of large colonies are difficult no matter how they’re made. However, when estimating bridge colonies, it would help if we knew the number, using an average horizontal foot of crevice.

The solution seemed easy. Two years ago, Glen Novinger, an MTBC member and I, inserted two, three-quarter-inch-thick wooden frames, each encompassing a square foot of interior space, into bridge crevices of the same width while the bats were out feeding. The idea was to later slowly remove them, forcing those roosting inside to exit into a cloth-lined bag from which we would count them.

However, the bats were full of surprises. The first night we waited patiently till half an hour after we’d seen the last ones leave—or at least that was what we thought! But when we approached to install our devices, roughly half remained inside. I couldn’t help but wonder how many emergence counts had missed those that, for whatever their reasons, didn’t emerge at sundown. (more…)

Texas Department of Transportation Celebrates Bats

8/28/18
By Merlin Tuttle

 

The Texas Department of Transportation (TxDOT) has set world records when it comes to helping bats, and that special help is paying big dividends for Texans and for countless visitors. Thanks to the enthusiastic early leadership of Supervising Bridge Engineer, Mark Bloschock and the continuing efforts of Stirling Robertson, now in charge of Strategic Projects, and John Young, an Environmental Specialist, TxDOT is taking great pride in its accomplishments.

On August 21, Stirling and John organized a special bat evening for 30 of TxDOT’s most important media and public information officers. They each received a copy of Department’s new guide to bat watching at state bridges, attended my 20-minute presentation at TxDOT headquarters, then joined me for a special Congress Avenue Bridge bat watching evening. We were delighted when we learned that Mark, who is now retired, would be able to join us.

The bats performed beautifully, and Stirling reported, “There has been overwhelming positive response to your talk and the whole event. Good stuff!” A big thank you to Stirling for making this event possible! We look forward to future collaboration and many more bats in Texas bridges.
