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 andselection 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…)
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.
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…)
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…)
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.”
CairnsMayor, 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.

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!
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…)
Today’s issue of TheScientist contains another outstanding example of how MTBC is making a unique, but critical difference for bats. This article [by Merlin Tuttle] was originally submitted as an email to the editor. On January 13, I explained the harm done by biased portrayal of bats. The editor promptly requested permission to publish my communication as an op-ed. We encourage our members to share it broadly. Nothing can threaten bats more than the fear and intolerance created by misleading disease stories.
Rousette fruit bats are essential pollinators and seed dispersers. They form colonies of many thousands in caves and abandoned mines where they are extremely vulnerable to extermination. Tens of thousands were killed at a single site in Uganda by humans overreacting to fear of Marburg virus.
Speculation linking bats to scary diseases has become lucrative, both in generating research grants and media readership. As historically documented, it can have devastating impact in fostering intolerance and even massive bat eradication. It also threatens the credibility of scientists and publishers and diverts critical public health funding from far higher priorities.
Many authors and publishers of such counterproductive speculation are well intended, just misinformed. If kindly approached with sound documentation of the harm being done, they are appreciative and can be extremely helpful as we have repeatedly demonstrated.
Lena Sun’s article, “On a Bat’s Wing and a Prayer,” in the December 13, 2018 edition of The Washington Post, though well intended, contains misinformation that can threaten both conservation and public health. It leads with two false premises: bats are “some of the most dangerous animals in the world” and the rare Marburg virus is an important threat to world health. (1)
This basic discovery was covered by several news media, each with a slightly different slant. We responded to this one because it contained the worst misrepresentations. It was the only one seen that claimed bats to be “some of the most dangerous animals in the world” in addition to exaggerating the seriousness of its threat to world health.
Since its discovery in 1967, Marburg virus has caused a dozen outbreaks, killing fewer than 400 people. All the so-called “emerging diseases” speculated to be associated with bats worldwide, have killed fewer than 20,000 people in the past 40 years.
By comparison, HIV from chimpanzees has killed more than 39 million people,(2) yet these more popular animals consistently escape being labeled as dangerous. Among other viral killers in Africa, the World Health Organization reports more than 70,000 children die annually from vaccine-preventable roto virus infections.(3) It also warns of geometric growth in obesity, that according to the National Institutes of Health causes 300,000 preventable deaths annually in the U.S. alone.(4) And by extremely conservative estimate, the U.S. Centers for Disease Control and Prevention reports more than 23,000 Americans die annually from antibiotic-resistant bacterial infections.(5)
So why are we focusing limited public health resources disproportionately on the rarest threats? And why are rare risks from bats often exaggerated? The answers are simple. Bats are little known, widely feared, easy to sample, and have few defenders. Also, new viruses can be found wherever we look. These combined facts make bats uniquely vulnerable to a seemingly perfect storm. Speculation linking them to equally little known, but scary viruses has proven extremely lucrative in gaining unprecedentedly large grants and media readership, while diverting limited public health funds from far higher priorities.(6)(7)
Historically, bats have one of our planet’s finest track records of living safely with humans. Millions live in cities from America to Africa, Asia, and Australia, and have not caused even one of the world’s great pandemics. Diseases associated with bats are easily avoidable, mostly by simply not handling them.(7) Until more is known about Marburg, African caves where the virus may exist should be avoided.
For those visiting Africa, risks from mosquito-transmitted malaria or dog-transmitted rabies are orders of magnitude higher than those from any of the so-called “emerging,” but ancient, diseases speculated to be associated with bats. Our real fears should focus on preventing further loss of these already alarmingly declining, but ecologically and economically essential animals.(7)
“Thank you so much for your concern, and for reading the bioGraphic story about Nipah virus. I really appreciate it. I assure you that I am a strong proponent of bats and the tremendously important ecological roles they play. I also think that bats are simply amazing creatures in their many forms and functions. (When you have time, please take a look at bioGraphic‘s other bat stories as evidence of that appreciation: Glimmers in the Dark, Battling Disease, Bat Ballet, and Agave Whisperers.)”
He went on to explain it is never his intention to vilify or advocate killing of bats and hopes he is being clear.

Dear Steven,
“I do not doubt your concern for bats or your good intentions. As I’ve commented, most of your article was just fine. My complaint lies in labeling bats to be the most dangerous disease-spreading mammals. Our background experiences are apparently strikingly different. Mine regarding the impact of public fear have been summarized recently. I’d be delighted to learn more about whatever experiences led you to your apparently differing concerns. However, I’d much prefer to simply share our perspectives over the phone.”

Dear Merlin,
“Thank you for your reply. I look forward to the opportunity to speak with you. I first heard of your research when I was an undergrad studying zoology and ecology at Colorado State in the late 80’s, so it would be an honor to “meet” by phone.”
He further notes that he extensively interviewed disease experts and explains, “You will see in the article that I chose my words very carefully. I did not say that ‘bats are the most dangerous disease-spreading mammals.’ Humans hold that dubious distinction. What I wrote is that, ‘Among mammals, bats rank number one in terms of their role in spreading zoonotic diseases.’ That statement is most certainly true, according to my sources, as well as published research such as this Nature paper published in June 2017.
He also noted, “Some of your followers have expressed concern that if people in Bangladesh understand where the virus is coming from that they will begin to persecute bats.”
[Merlin’s thoughts—That is a serious misunderstanding. Scientists and conservationists have a responsibility to inform the public of disease sources, locations, and how to avoid them. We also must condemn sensational speculation and exaggeration, either of which can seriously harm both public health and bats.]
12/21/18 Merlin response
Dear Steven,
As per your suggestion, I’ve read your recent stories from bioGraphic and congratulate you on some very fine promotion of bat values. In fact, your “Glimmers in the Dark” article is the best I’ve seen on WNS. Given your clear concern for bats, I’m especially looking forward to speaking with you by phone when you return early in the New Year. When ready, simply suggest a time and phone number, and I’ll be happy to call.

We’ve likely had rather different experiences on the impact of exaggerated disease fears. Unlike you, I’ve had the misfortune of repeatedly seeing the results first hand.
During my early research in Tennessee, I met cave owners who burned many thousands of endangered gray bats by lighting kerosene in their roosts due to exaggerated rabies warnings. In Mexico, I took the attached photo of a few of the estimated 250,000 skeletons of insect-eating bats we found on reopening a roost where a fearful owner had sealed the bats inside. And, while photographing bats for my 2014 National Geographic article, I found a major bat cave recently sealed (with the bats inside) due to disease fears in a Cuban national park. In my experience, people seldom tolerate and often kill animals they fear. In fact, the free-tailed bat colony speculated to have been the source of the 2014 Ebola outbreak was burned in its roost.
Seeing how well intended you are, I hope you will read my 2017 report on fear-motivated bat killing and its impact on conservation. I am quite familiar with the Nature paper reporting that bats harbor a significantly higher proportion of zoonotic viruses than any other mammal group and look forward to discussing it with you.
[Note that Merlin has rebutted the aforementioned Nature article, read his response HERE.]
