A Model Example of Bat Recovery Potential

By Merlin Tuttle
9/25/19

 

Long Cave, in Kentucky, like many others, has a long history of human occupation with little record of prior use by bats. It was mined for saltpeter, a key ingredient of gun powder, during the war of 1812 and was subject to commercial tourism, probably beginning at about the turn of the century, ending by the 1930s.

Huge passages trapped cold air and remained cool year-round, offering major opportunities for bat hibernation. Roost stains from past bat use were widespread, and the cave clearly had potential to shelter millions. As recently as 1947 some 50,000 bats, presumed to be largely the now endangered Indiana myotis (Myotis sodalis), continued to return in winter. Nevertheless, entrance barriers built to exclude non-paying tourists, increasingly restricted air flow, eventually culminating in a concrete wall and a nearly solid door. (more…)

Doug Gimesy ranks among the very best when it comes to wildlife photographers. His numerous awards include winning the Wildscreen Panda Photo Story Award in 2018 and selection as the Australian Geographic Nature Photographer of the Year in 2019. But most importantly he is changing the way the world thinks about nature, having a heart for Australia’s much maligned flying foxes. He explains, “My hope is that the images and information I share will inspire people to stop, think, and treat the world a little more kindly.”

Doug is persuasively teaching the world about Australia’s flying foxes, from his story, “Night Gardeners” in the BBC Wildlife Magazine to “Urban battler” in Australian Geographic. View more of his flying fox photos on his site. (more…)

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.

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.”

Thank You For Your Voice – Editors are Listening and Bats are Benefiting

By Merlin Tuttle
6/27/19

A reminder that our members DO make a difference! Leading news media outlets are changing tack, publishing more positive, and fewer negative, stories about bats as a direct result of MTBC members’ ongoing support and actions.

Your vigilance brings misleading articles to our attention. Your support enables us to carefully document and explain issues of concern. Your personal, diplomatic comments to editors influence their further actions. Media portrayal of bats cannot be ignored. It is key to broad public understanding and support, without which conservation progress could prove impossible.

The intermediate horseshoe bat (Rhinolophus affinis) ranges from northern India to southern China. It is one of the horseshoe bats speculated, but still unproven to have caused the SARS epidemic.

Since 2014, we’ve prepared and distributed 15 blog posts and 18 Bat Flashes providing counterpoint documentation in response to exaggerated, misleading, and often completely wrong speculation attempting to link bats to rare, but scary diseases. Widely distributed publications included “Give Bats a Break” in Issues in Science and Technology (subsequently translated into French and Chinese), “Fear of Bats and its Consequences” in the Journal of Bat Research and Conservation, and “Humans Shouldn’t Be So Scared of Bats” in Slate. Additionally, the science journal, Nature, published a co-authored response in its correspondence section, titled “Don’t misrepresent link between bats and SARS.” (more…)

Bat Flash! New York Times Misrepresents Rabies Facts

 

Merlin Tuttle’s Response
6/25/19

For at least the second time this year, The New York Times has published facts involving bats and disease in a misleading manner. At a time when bats are in special need of conservation, scary speculation is extremely counterproductive. In February of this year, we issued a Bat Flash, and members contacted Times authors and editors to caution them about the negative impact of premature disease speculation.

Now bats need you to speak up again. On June 14, 2019, I responded with the following communication to The New York Times Editor:

I read with interest the recent article, “Bats, Not Dogs, Are the Most Common Source of Rabies,” by James Gorman. As a biologist who has studied and photographed hundreds of species of bats worldwide, I have personally documented instances in which thousands, even millions of bats have been burned in their caves due to misleading warnings that incite needless fear. In fact, fear of bats is often the single greatest impediment to their conservation.

I’m deeply concerned because bats are essential to whole economies and ecosystems upon which we, ourselves, depend. Their loss threatens our future, far more than any possible disease transmission. Education regarding the benefits of conserving bats is urgently needed. (more…)

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…)
