Bat Flash! Respond to Sensationalized Bat Attack Report

By Merlin Tuttle
6/12/17

Bats are currently facing the most harmful media campaign seen in more than 30 years. The latest outrage is an article titled “Bat attacks on humans increasing due to urbanization and deforestation,” published in the British online newspaper, The Independent, on June 3, 2017.

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.

Common vampire bats (Desmodus rotundus) are found only in Latin America. They appear to have been relatively rare prior to the arrival of modern humans who brought livestock that these bats now feed on. Though they have become a problem for ranchers, vampire saliva is reported to contain a “treasure trove” of molecules that one day may be used to save human lives. They are highly social animals that adopt orphans and share meals with less fortunate colony members.

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.

New Bat House Research Project

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 Inappropriate Coverage of Bats and Ebola in Smithsonian Publication

Response to Smithsonian story, “Can Saving Animals Prevent the Next Deadly Pandemic?”
Merlin Tuttle
5/9/17

 

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.

Hundreds of thousands of Straw-colored fruit bats (Eidolon helvum) beginning their evening departure from a city park in Ivory Coast, Africa. Cities often provide the only homes safe from commercial hunters who sell them for people to eat. Despite such large numbers having lived in close association with humans throughout recorded history, they have not caused disease outbreaks. Their remarkable safety record casts grave doubt on recent speculation of their being dangerous carriers of disease.

Return of “Batgirl” Alexis

Alexis won 1st place & Grand Champ, the 2017 SASEF Regional Science Fair.

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.

New Publication in Defense of Bats

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.

Praise for Speaking Up for Neglected Bats – BAT FLASH

Praise for Speaking Up for Neglected Bats
By Merlin Tuttle

Many thanks to Anthropocene for their timely alert, Wind energy is tough on bats—but it doesn’t have to be that way, by Brandon Keim in their March 15, 2017 issue.

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.

Merlin Tuttle and Jessica Kern examine bats killed by wind turbines in West Virginia, where Merlin led early efforts to minimize bat kills.

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.

BAT FLASH! Sensational NPR Story Threatens Bats

Sensational National Public Radio Story Threatens Bats
By Merlin Tuttle
2/14/17

 

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.

Australian Flying Foxes Need Help

By Merlin Tuttle
1/10/17

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.

Gray-headed and other flying foxes are essential pollinators and seed dispersers for Australian forests. However, they are killed in massive numbers during occasional droughts when native trees fail to flower, forcing them to resort ot orchard fruit which could be protected with netting.

However, they are killed in massive numbers during occasional droughts when native trees fail to flower, forcing them to resort to orchard fruit which could be protected with netting.

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 Australiagrey-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.

Response to long-term oil & gas draft permit proposal

Merlin has been asked to comment on the U.S. Fish and Wildlife proposal to prepare a draft of a 50-year environmental impact statement that will affect bats and humans.

Proposal Summary–The U.S. Fish and Wildlife Service, announces their intent to prepare a draft environmental impact statement (EIS) for proposed issuance of an incidental take permit (ITP) under the Endangered Species Act (ESA) for the draft Oil & Gas Coalition Multi-State Habitat Conservation Plan (O&G HCP). The O&G HCP is being developed to streamline environmental permitting and compliance with the ESA for nine companies in conjunction with their respective midstream and upstream oil and gas exploration, production, and maintenance activities in Ohio, Pennsylvania, and West Virginia over a 50-year period. The companies have indicated that they intend to request ITP coverage for five bat species: The endangered Indiana bat (Myotis sodalis), the threatened northern long-eared bat (Myotis septentrionalis), the little brown bat (Myotis lucifugus), the eastern small-footed bat (Myotis leibii), and the tri-colored bat (Perimyotis subflavus).

For more information and details about the intended proposal, click HERE.

Merlin has provided his statement below after discussing the proposal with a U.S. FWS representative.

We invite you to leave your comments as well via this link. The deadline for comments is December 27th.
