I wholeheartedly applaud Atlantic Monthly’s defense of bats at a time when so many other publications are spreading grossly exaggerated stories attempting to link bats to some of the world’s rarest but also scariest diseases. Bats have never needed help more, nor have we needed them more! As the one who persuaded the citizens of Austin to protect instead of eradicating its now world-famous colony, I’m proud to report that none of millions of tourists who come to enjoy their spectacular emergences has ever been harmed. By simply leaving bats alone (not attempting to handle them), we have exceedingly little to fear and much to gain. Our bats eat tons of crop and yard pests every summer night and attract millions of tourist dollars each year.
Thanks to people who increasingly understand and help bats, even those species most devastated by WNS are gradually beginning to recover. The only cure will come from improved protection and restoration of key bat habitats, especially their hibernation caves. It’s far too late, as well as impractical, to find a cure for WNS. Going forward, all resources should be devoted to recovery.
While leading news media, from The Wall Street Journal to Time magazine, were maligning bats with an unprecedented flood of scary stories threatening terrible disease pandemics, Merlin was busy setting the record straight.
At the annual banquet of the National Speleological Society, in New Mexico, he thanked members for their invaluable service to bats over the past 40 years, especially mentioning their volunteered help in reporting key bat caves in need of protection, designing and building the world’s finest protective gates at hundreds of locations, and helping educate cave owners regarding bat values and needs. He also credited them with leadership essential to recovery of the federally endangered gray bat (Myotis grisescens) and thanked them for their generous help during the white-nose syndrome (WNS) crisis.
Merlin has since agreed to collaborate with National Speleological Society leadership on behalf of improving management policies to better protect important caves for both bats and cavers.
As the featured speaker for the Association of Medical Illustrators 2017 annual conference, Merlin was asked to share his “Win friends, not battles” conservation philosophy. Of course, they also enthusiastically learned a lot about bats as well! The group’s real mission is medical education, making them an ideal audience at a time when there are so many gross exaggerations linking bats to disease.
Many stayed to ask questions for an extra 45 minutes. At a time when so many disagreements become too confrontational to permit reasoned progress, Merlin’s positive approaches struck a special cord.
Once again, bats are plagued with a rash of sensational bat-attack and bat-disease stories, promoted by clever, but unscrupulous persons who know better. The motivation remains the same—greedy competition for public health funding. As noted by Mexico’s leading bat biologist and conservationist, Dr. Rodrigo Medellin, “unsupported statements and partial truths have been cleverly interwoven to present a picture that bats are the most dangerous, filthy, pathogen-harboring organisms on earth.” So-called virus hunters are linking already feared bats with deadly, but rare diseases, misleading governments to invest billions of dollars in projects of questionable value in saving human lives (USCDC 2015).
The current article in The Independent, is typical, first the scary headline that leaves a lasting impression on readers, despite later qualifiers, most of which go unread. The subtitle says, “Diseases in bats have been around for a long time and historically have not been a problem. Now, there is cause for concern.”
Those promoting this international campaign of fear are clever wordsmithers. They know just enough about bats and diseases to almost imperceptibly distort the truth, scaring people about potential, but unlikely events. Extremely low risks are made to seem imminent and possibly disastrous. And since neither bats nor viruses are well understood, they are ideal victims for such manipulation.
The article claims bats have been attacking humans in increasing numbers because their natural habitats are being destroyed through deforestation. This is a commonly propagated myth in recent scare stories. It appears to be an attempt to look like the writer isn’t anti-bat, but is simply attempting to be helpful. Bats nearly everywhere are in decline, and a growing proportion of the human population now lives in cities where there is less, rather than more likelihood of contact with bats. A veterinary college professor is quoted as saying that expanding cities are causing increasing contact—just the opposite of reality. The professor sounds like a reliable source, though he likely has no personal experience with bats.
It is reported that more than 40 people were bitten by vampires in just three months, with one death from rabies. But that’s in all of northeastern Brazil. This is likely one of the rarest causes of mortality that could have been reported for such a large area. Far more deaths likely occurred from bicycle accidents or dog attacks, though no one is likely to advocate ridding the area of bicycles or dogs!
The story verifies our worst concerns, reporting that authorities are “trying to control the bats, poisoning them and removing their roosting sites.” Highly beneficial species form the largest, most conspicuous colonies so they are the ones most easily found, becoming innocent victims of mass killing. In the current article, a doctor stresses that “Brazilian authorities must take the threat seriously.” And an accompanying photo shows an insect-eating bat, looking exceptionally vicious because it is snarling in self-defense.
Not until the next to last paragraph is it admitted that “Bats in the UK do not pose a threat to the human population.” This nearly universally repeated approach gives authors a disclaimer, but it appears deliberately located where it is least likely to be noticed.

Loss of natural homes in caves and old-growth forests is one of the greatest causes of bat decline worldwide. Unfortunately, many former roosts can never be replaced, leaving an increasingly urgent need for alternative shelter. Wildlife Biologist, Steve Barlow, was one of the first to test the suitability of extra large designs, and he has been experimenting for nearly 20 years. Recently he has supplied his Big Bat House design to nature centers, city parks, wildlife refuges, farmers and private landowners.
Last October, Merlin met with Steve and they agreed to collaborate in developing a new, design that they hope will be even more attractive to bats. Their research proposal was generously funded by MTBC members, Joe and Sharon Goldston, with additional help from Steve. In early April Merlin spent two days with Steve and his construction crew in Kansas brainstorming anticipated improvements.
The result is a new modular design that is much less costly to build and lighter in weight. We also anticipate it’s being even more attractive to bats. It can be mounted on just two instead of four poles, and when a first module fills, more can be added, each one housing up to 4,000 bats. Based on past experience it is quite likely that, at some locations tens of thousands can be attracted, as ability to expand will be unlimited.
In early May, the first modules were installed on three farms in Florida, under Steve’s supervision. Test sites were each surrounded by a different kind of agricultural use in anticipation of a second research phase to investigate the bats’ impact on crop pests. Assuming bat acceptance, this should be a big step.
Two additional modules of the same design will be shipped for testing in Panama, hopefully to be installed by July. The first will be in a lowland rice-growing area, the second in a mountainous nature reserve. We believe all five sites have excellent potential to attract colonies in their first year, but we’ll have to be patient! Merlin’s first extra large roost, built at the University of Florida in Gainesville, took three years to attract bats. However, the colony rapidly grew to roughly 250,000!
Response to Smithsonian story, “Can Saving Animals Prevent the Next Deadly Pandemic?” Merlin Tuttle
Lorraine Boissoneault’s story, Can Saving Animals Prevent the Next Deadly Pandemic?, is clearly well intended. However, when it comes to fruit bats and Ebola it is based on outdated speculation that threatens serious harm to a group of mammals that is already in alarming decline. For a summary of current knowledge of bats versus Ebola and other rare, but so-called emerging diseases, and their speculated association with bats, I refer you to my article in the current edition of Issues in Science and Technology, titled “Give Bats a Break.”
Diseases that are millions of years old, but that are just now being discovered due to their rarity, are being referred to as “emerging” as an apparent public relations ploy to make them sound more dangerous. And speculating associations with bats makes them even more scary, since many people already fear bats. This has proven unprecedentedly effective in gaining hundreds of millions of dollars in grants to support so-called virus hunters, who must continue speculating about potentially dire threats from bat diseases to keep their grants flowing.
Bats historically have one of the world’s finest records of living safely with humans, first in caves and thatched huts, then in log cabins.
I have a very special treat, especially for those of you who have wondered what our bat prodigy, Alexis Valentine, has been up to lately. We met Alexis following one of Merlin’s lectures in 2014. She had been winning science fair prizes for her work with bats and speaking annually at the local Rotary Club since the third grade. She also had begun her own research on bats in the Great Smoky Mountains National Park. (Read past blog posts, Letters from a Young Scientist 1 – 10) Alexis still keeps in touch, and we are very proud of Batgirl! She’s still competing and winning in science fairs, speaking at professional bat conferences, conducting continuing bat research in the Great Smoky Mountain National Park, and enlightening folks about the many benefits of bats to people. I hope you enjoy reading about Alexis’ most recent activities in her own words as much as I do. Please join me in giving her a big “atta(bat)girl”! For young people interested in starting their own early careers in science and conservation, Merlin has just posted a new resource, titled Advice for Young People Interested in Science and Conservation.
Read Merlin’s article, Give Bats a Break, in the Spring 2017 edition of Issues in Science and Technology. This report is based on Merlin’s review of thousands of scientific papers and popular media stories. And it is the first to expose how sensational speculation is fostering bad science in a self-perpetuating cycle of misdirected public health funding that threatens the future of bats. This is an issue that we cannot ignore.
Over the past decade a growing number of peer-reviewed research publications have reported likely-to-be-unsustainable bat kills at wind turbines, also reporting that kills could be reduced by 44-90% by slightly delaying turbine cut-in speeds (the wind speeds at which turbines are activated to begin rotating to produce energy) during the bats’ fall migration.
The best available calculations indicate that by implementing these changes, annual power output would be reduced by less than 1%. Yet only a few companies have acted on even these economically feasible recommendations, despite repeated warnings that whole species could be threatened with extinction without prompt action. Keim raises the obvious question, “how people already know so much about solving the problem, yet do so little.” The answer seems obvious—Too many people still don’t know, and too many of us who do have remained silent for too long.
Please take a moment to thank author, Brandon Keim, and the editorial staff at Anthropocene for reminding readers that alarming and growing numbers of ecologically essential bats are being killed needlessly by carelessly operated wind turbines.

Sensational National Public Radio Story Threatens Bats By Merlin Tuttle
Unfortunately, the normally objective and reliable NPR, in its broadcast interview titled, Why Killer Viruses Are On The Rise, has joined in spreading irresponsibly sensational fear of bats. The interview with a “virus hunter” is set in a Bornean rainforest. In the preamble, the announcer notes that, “It’s where deadly viruses hide out, waiting their chance to leap into a person and then spread around the world.”
At a time when bats and rainforests are both in alarming decline, and in desperate need of protection, the program goes on to portray them in the scariest of terms. The reporter notes that rainforests “have lots of crazy animals” that “have lots of crazy viruses” and explains that what the virus hunter “really wants is to catch a bat.”
When the first bat is caught it is described as cute, but the reporter quickly points out that, “bats are arguably one of the most dangerous animals in the world. They triggered the Ebola outbreak in West Africa, the pandemic of killer pneumonia back in 2003, that was called SARS, and they’re behind one of the viruses scientists think could cause the next big one, Nipah.” This is unproven speculation reported as fact. But it gets even worse.
As one who in 1985 played a lead role in convincing the New South Wales (NSW) Minister for the Environment and Planning, Bob Carr, to provide statewide protection for flying foxes, I am extremely disappointed to see such progress reversed decades later by a predecessor. Grey-headed flying foxes are essential pollinators and seed dispersers upon which many of Australia’s unique plants and animals rely.
Nevertheless, their numbers have declined dramatically over the past hundred years. They first were massively exterminated by fruit growers, because during periodic droughts, when forests failed to flower, starving bats would invade orchards. Thanks to excellent research, orchards can now be protected. However, the bats’ traditional roosting habitats often have been overrun by urbanization. Once again these bats are in trouble, often with few options remaining. In small numbers, they may be enjoyed. But during unpredictable spikes in gum tree flowering, these sophisticated commuters can be attracted long distances. When bats weighing up to two pounds and having wingspans of more than three feet suddenly increase by as much as 10-fold, noise and odor can become a serious problem.
Excellent means of protecting fruit orchards have been developed, but urban nuisances have not yet been studied sufficiently to find viable solutions. As flying fox experts, Justin Welbergen and Peggy Eby recently explained in their insightful article, Not in my backyard? How to live alongside flying foxes in urban Australia, grey-headed flying foxes can travel thousands of kilometers in a single year and quickly respond to changing conditions far beyond the boundaries of any one state. To resolve nuisances without loss of essential services, we must learn much more about what attracts them to specific roosts and how best to provide suitable alternatives when their choices create nuisances.
