Bats' echolocation strategy: How dense colonies avoid mid-air collisions
https://phys.org/news/2025-03-echolocation-strategy-dense-colonies-mid.html paper: https://www.pnas.org/doi/10.1073/pnas.2407810122
"When exiting the cave, #bats experience a cacophony of calls, with 94% of echolocations being jammed. Yet, within five seconds of leaving the cave, bats significantly reduced the #echolocation jamming... they fanned out and they emitted shorter and weaker calls at higher frequency... to gain detailed information about their near neighbors... to avoid collisions."

26/03/2025 - Slow-mo bat flight
Evening walk after work. Nice to see the bats back out round sunset. It was still quite light, normally more into twilight before we see them. Bats are so magic to watch fly.

A Surprisingly Simple Solution to Protect #Birds From #WindTurbines Gets its Biggest Test Yet
Painting one turbine blade black has shown promise for preventing collisions. Now researchers are seeing if it can work in #Wyoming.
By Kylie Mohr, Summer 2024
"A year ago, a Golden Eagle approaching the Glenrock/Rolling Hills wind farm in Wyoming might have seen a dangerous optical illusion: A turbine’s blades, spinning at more than 150 miles per hour, would appear not as solid objects to be avoided, but as a blur the bird could fly through. Scientists believe this disorienting visual phenomenon, known as motion smear, contributes to the collisions that kill an estimated 140,000 to 679,000 birds per year at #WindFarms in the United States.
"The same eagle soaring over the area’s scrubby sagebrush today will see warning signs. Those once indistinct and innocuous-seeming blurs will present clearly as physical masses, signaling to birds that they should steer clear.
"Such is the hope, anyway, of a study now testing a surprisingly simple tool for making wind farms less hazardous to birds: black paint. This summer, PacifiCorp, which owns the facility, aims to finish painting one blade on each of 36 turbines there. Over the next several years the company and its partners, including the federal government, will keep track of how many eagles and other daytime-flying birds those turbines kill compared to their previous toll and to the remaining 100 or so that have not been painted. Search teams will look for eagle carcasses, while specially trained dogs will sniff out other birds and #bats. 'We’re trying to have as little impact as possible while also trying to provide electricity to customers,' says Jona Whitesides, a spokesperson for PacifiCorp."

6 Ways to Protect #Bats and #Birds From #WindTurbines
By Russell McLendon
Published October 22, 2019
"Wind turbines are an important source of clean, #renewable energy. They're one of the fastest-growing power sources in the U.S., outpacing even natural gas. Unfortunately, they also sometimes kill birds and bats.
"That may sound like an environmental Catch-22, but it doesn't need to be. From new designs and smarter locations to high-tech tracking systems and ultrasonic 'boom boxes,' many American #WindFarms are experimenting with various ways to make their turbines safer for flying #wildlife. "

Aujourd'hui je vous présente la Barbastelle d'Europe ! Une petite chauve-souris au physique plutôt atypique avec des oreilles très larges "attachés" au sommet du crâne, un pelage très sombre, assez long. La Barbastelle est une espèce plutôt forestière, elle aime particulièrement les écorces décollées des arbres pour s'y cacher

Book review: The Secret Lives of Bats: My Adventures with the World's Most Misunderstood Mammals - Merlin Tuttle
www.goodreads.comRamon van Dam's review of The Secret Lives of Bats4/5: What a lovely, informative and interesting book about the fascinating world of bats. Merlin Tuttle is clearly one of the top experts on the field, and his photographs are nothing less than amazing. I did have a small gripe with the writing style: all chapters begin with an anecdote to reel you in, but personally I don't think that's needed every single time. Just tell us the stories, they are great as they are. That's just a minor smudge though, I thoroughly enjoyed this and learned quite a lot.
The #bats are out! Thought I saw one yesterday but definitely here tonight.
None in the picture though.
My latest article about bats in Japanese folklore and art has just been published. Amazingly I've also just passed 1000 subscribers to my free newsletter in just over five weeks. I'm SO grateful for the support. Link to the article is below, I hope you enjoy it.
