WNS: Can a Cure Be Effective?

7/12/2019
By Merin Tuttle

 

Amid media announcements that the fungus that causes white-nose syndrome in bats has spread to California, and growing public concern, The Wildlife Society announced the most recent attempt to find a cure. On July 9, an article titled “Bacteria treatment helps bats survive white-nose syndrome,” suggested progress toward a cure. However, there is no evidence that human intervention can slow the spread or cure the disease. As I’ve reported, the best available studies from the Northeast indicate that population recovery at key sites is exceeding expectations, and that a cure is unnecessary, impractical to implement, and risks unintended negative consequences.

Skybridge Academy is doing something new! While many school administrators might panic at the sight of a bat in the yard, Ariel Miller, founder of the school in Dripping Springs, Texas, recently invited us to install two bat houses in her schoolyard. She hopes to attract hundreds of Brazilian free-tailed bats (Tadarida brasiliensis) and use them as teaching aids across Skybridge’s custom-made curriculum.

 

To put it mildly, the school is innovative! The yard includes a pair of pigs, a beehive, a vegetable garden, and now deluxe housing for bats. Students choose their own subjects and learn practical skills, completely omitting standardized testing. Skybridge alumni have an outstanding track record of achievement regardless of whether they opt to pursue higher education or another career path. (more…)

Bats: An Illustrated Guide to All Species Gains Top Reviews and Sales

7/1/19
By Merlin Tuttle

The American version of BATS: An Illustrated Guide to All Species, published by the Smithsonian Institution, sold its first print run of over 5,000 copies in just three months. It also received high accolades from the science journal Nature and a prestigious Star Award from the Library Journal. The Library Journal verdict? “Far beyond the practical value of a guidebook, this is an important update to bat literature and one to savor, containing a wonder on nearly every page and proving that bats are indeed ‘intelligent, curious, comical, even essential animals.'”

The science journal Nature reported, “This guide by writer Marianne Taylor and bat conservationist Merlin Tuttle shines a light on the order Chiroptera, from the wee Kitti’s hog-nosed bat (Craseonycteris thonglongyai, a candidate for world’s smallest mammal) to the ‘megabats’ of the Pteropodidae family. Meshing deft scientific text with Tuttle’s sumptuous images, it’s a superb introduction to the baroque morphologies and flying prowess of these beguiling beasts.”

Cave Management Workshop with Bat Survey Solutions

5/22/19
By Merlin Tuttle

Merlin explains “chimney-effect” air flow and its key importance in providing cave-dwelling bats with cold roosts for hibernation and warm ones for rearing young.

Loss of essential roosts, especially those in caves, appears to be the most important cause of North American bat decline and endangerment. Millions of bats have been lost from single caves, initially due to saltpeter extraction for gun powder, and later when they were further altered for tourism. Some caves were even burned due to exaggerated fear of bats.

In recent decades, there have been numerous opportunities to recognize mistakes from the past as well as opportunities for the future. One way to address these issues is through cave management training.
Bat Survey Solutions held a workshop in San Marcos, Texas from May 7-9, where attendees were provided with examples of a variety of case histories and what they’ve taught us.

Member Night Bat Cruise

4/12/19
By Merlin Tuttle

This year’s member night bat cruise was, as usual, a fun event and included MTBC members from as far away as the United Kingdom. Due to unusually frequent spring showers, the bats have been waiting till sundown to emerge, but are still attracting large crowds of viewers.

Our April 12 cruise participants enjoyed a large, three-column emergence that began soon after sundown. If our August 16 cruise is equal to those of the past three years, the emergence will begin before sundown and include four great columns, a truly spectacular event, the best of the year. Leadership and above members receive first-priority bookings for these free nights with me and our staff. Space is limited. Make your reservations early. Don’t miss out!

Millions of tourists have watched free-tailed bat emergences from the Congress Avenue Bridge in Austin, Texas over the past 35 years without anyone ever having been harmed.

Bat Flash! Step Two to Help Cairns’ Flying Foxes

(Scroll down for action links!)

We want to thank each of you who contacted Mayor Bob Manning in response to our Bat Flash in March on behalf of an urgent threat to Australia’s now critically endangered spectacled flying foxes. We appear to be having important impact, as just reported by Sera Steves, Secretary, Bats and Trees Society of Cairns.

“The mayor and council are visibly and vocally struck by the amount of email responses they’ve gotten, good work! However, they continue to hide behind the false idea that a dispersal is for the good of the bats. The welfare argument needs to be shot out of the air and the focus needs to be on tourism potential. The feedback from tourists proved valuable in response to an article in the Cairns post about dispersing the bats with pool noodles, pyrotechnics, gas guns, stock whips and air horns.”

Another step is still needed…

Bat Association at Texas State Lecture

The Bat Association at Texas State University (BATS) in San Marcos is only a few months old, but already boasts more than 150 members. Its mission is to raise awareness and concern for these long neglected, but essential animals.

Merlin Tuttle speaking to the Texas State Bat Association at Texas State University.

The organization’s three main goals are to share hands-on opportunities to learn about bats, network with professionals, and spread awareness of bat values and needs. It is led by Jacob Rogers (President) and Danielle Cordani (Vice President), under the supervision of Assistant Professor, Sarah Fritts. They’re planning a wide variety of special events to raise interest and concern, including field trips, invited lectures, bat house building projects, and opportunities for graduate students to share their experiences.

 

Merlin was their invited speaker on February 26. His topic, “Planning a Career—Why Bats?” His mission was to introduce bats as a too-long overlooked gold mine of research need and opportunity and to provide tips on how to succeed as a scientist. His advice–Follow your passion. Address issues most relevant to humans. Practice strong science. Seek mentor opportunities. And learn to entertain. Of course, the message was well illustrated with “How to” examples, including photography and public sharing.

The response was overwhelming. Following his formal presentation, he was peppered with enthusiastic questions for another hour.

Atlas Obscura’s SXSW Bat Watching Evening with Merlin

By Teresa Nichta
3/15/19

Atlas Obscura features travel, exploration and hosts a collaborative guide to worldwide locations of special interest. Bats seem a perfect fit with a publication featuring the world’s hidden wonders! This week, they hosted their first Austin bat watching event, an armada of more than 50 kayakers, led by organization co-founder Dylan Thuras and Merlin Tuttle and sponsored by SXSWGore-Tex and Congress Avenue Kayaks.

Merlin provided a brief dockside introduction to the Congress Avenue Bridge’s famous free-tailed bats and an introduction to the diversity and importance of bats worldwide. Participants came from as far away as Australia and Brazil and peppered Merlin with enthusiastic questions. The event was so popular that an unfortunately large number of hopeful registrants had to be turned away.

It was a beautiful spring evening, and some 200,000 overwintering bats emerged prior to sundown. Hundreds of thousands more are expected to arrive soon, migrating north from overwintering caves in Mexico. Unusual entertainment was provided by two small falcons, extraordinarily determined to feast on bats. Fortunately for viewers rooting for the bats, these two hawks turned out to be the least competent bat catchers Merlin has ever seen. We counted more than 20 failed chases! (more…)

Bat Flash! Australian Flying Foxes Urgently Need Immediate Help

Cairns Mayor, Bob Manning, wants to force flying fox survivors to leave his city. This is planned for the near future, making it an urgent issue. Recent heat stress and starvation have killed 1/3 of the flying foxes in his city. Survivors remain in grave danger. One simple, impactful thing we can do is email this Australian mayor, b.manning@cairns.qld.gov.au, politely asking him to stop all planned efforts to chase endangered flying foxes from their traditional homes in Cairns. They’re already desperate, and many more may die if forced to move.

We must learn to live in harmony with nature! Please visit the link in our bio for more about climate change and flying foxes. Also, follow @sera_loves_crocs on Instagram as well as BATSOC (Bats and Trees Society of Cairns) @batsandtreessocietyofcairns, on Instagram and Facebook for further updates and details.

 

 

TAKE ACTION!

Our combined voices can make a difference. Send an email to Mayor Bob Manning to politely make him aware of international concern for Australia’s flying foxes. Cairns is a major tourist destination where potential visitors have extraordinary influence. He just needs to know you like flying foxes and hope to see them protected as some of his country’s most valuable and fascinating wildlife. It’s numbers that count. Australia’s flying foxes need all of you!

Bat Flash! Scientific Credibility Under Siege—Sound Data Versus Premature Speculation

By Merlin Tuttle
2/21/19

Just as we enter a period of exceptional need for reliable science to protect and restore a healthy planet, too many traditionally prestigious science journals and institutions are rewarding bad science. (1) (2) “Scientists are supposed to relentlessly probe the fabric of reality with the most rigorous and skeptical of methods.” (3) Yet traditionally credible journals like Nature and Science are increasingly publishing sensational speculation, particularly studies attempting to link bats to deadly diseases. (4)

Growing numbers are attempting to prove rather than test hypotheses, sometimes based on a sample of just one viral fragment from a single bat. (5) Kai Kupferschmidt’s article titled, “This bat species may be the source of the Ebola epidemic that killed more than 11,000 people in West Africa,” exemplifies the problem. It is based on a highly questionable sample from one bat, though it appeared in the online news site of the journal Science (January 24, 2019).

The common bent-winged bat lives in caves and cave-like locations from southern Europe to Japan and Southeast Asia to China, the Philippines and Solomon Islands, most of Africa and eastern Australia. It is insectivorous, often feeding on small beetles, and forms large colonies, some exceeding 100,000 individuals.

As is typical in such stories, it begins with a scary question that will grab readership and media attention. That Science title is followed by a emboldened quote stating that “This is an important new lead and it should be followed up extensively.”

Later quotes, less emphasized, admit that only a small viral fragment was found, and that it may have come from an infected insect eaten by the bat. In other words, this bat may have simply eaten an Ebola-carrying insect, completely changing the bat’s role from implied source to controller. Perhaps if virologists weren’t so focused on proving that Ebola comes from bats, they might have found the true source by now.

A growing number of leading virologists are warning that virus hunting, promoted by such articles, is a costly waste. The unsupportable public health promises being made are likely to demean the credibility of science. (6) Scientists need incentives for finding the right answer rather than for simply getting published. (1)

Kupferschmidt’s article ends with a warning that bats shouldn’t be killed. However, as already documented, people seldom tolerate and often kill animals they fear, especially bats. (7) (8)

The New York Times ran a similar account of the same story, authored by Denise Grady. It was titled “Deadly Ebola Virus Is Found in Liberian Bat, Researchers Say.” The author admits “It feels premature scientifically” but fails to admit that the small viral fragment may have come from an infected insect eaten by the bat, making the bat a potential aid in limiting the spread of Ebola. They too, belatedly and ineffectively, admonish not to kill bats.

Sensational and premature reports like these are clearly irresponsible and risk great harm to both scientific credibility and the environment. (more…)
