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!

Slate Magazine Goes to Bat for Bats

Countering a huge, international disease scare campaign against bats is extremely challenging, but thanks to the loyal support of our uniquely dedicated members the truth is being heard, as seen in this week’s issue of Slate magazine. We are unfortunately still the only conservation organization brave enough to counter this international campaign backed by hundreds of millions of dollars. Promoters of fear are increasingly portraying themselves as bat conservationists attempting to help bats. They say bats are valuable and shouldn’t be killed, but their grossly exaggerated disease warnings remain deadly, no less than back in the 1970’s and early 1980’s when nearly everyone in America was led to believe that most bats were rabid. The impact on conservation efforts was devastating. States with the most indefensibly large rabies budgets led the propaganda, aided by unscrupulous pest control companies. However, states where health departments intensely publicized bats as dangerous achieved no reduction in human rabies compared to states that simply advised evaluation of all animal bites.

Too few of us today remember that, after Rachael Carson got DDT outlawed for general use in America, our CDC insisted on obtaining a special exemption so it could continue to use DDT to kill bats in buildings. Even now, our CDC has a policy that Canada and the State of Oregon have rejected, based on independent scientific evaluation.

A large proportion of remaining bats have had to take refuge in buildings​, having lost their traditional roosts in caves and old growth forests​. Yet I’m seeing a gradual return to the days of big bat business for exterminators. Now, they try to look like conservationists by including mention of how beneficial bats are and ​advising that they should not be killed while simultaneously attempting to scare people into hiring their eviction services, which less conspicuously still kills bats. With all the devastation already wrought by WNS in the U.S., the timing for intolerance couldn’t be worse.

That’s why we urge you to compliment Slate on setting the record straight. Leave a comment on the article, call (212) 445-5330 or email slateoffice@slate.com.

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.

Updated Wind Energy Resources

Updated Wind Energy Resources

By Merlin Tuttle
4/3/17
Next to irrational fear, wind power production now poses the greatest threat to bats, especially in industrialized countries. The full impact of this exponentially growing industry remains largely unmeasured and unreported, but available evidence is alarming. Wind production companies, widely viewed as “green,” have not lived up to their reputation, and too many conservationists have remained silent for far too long. Bat researchers have worked diligently to help wind energy producers become truly green. However, only a small proportion of companies have implemented even the most cost-effective measures. 
As Merlin reports in his updated resource documents, it’s difficult to explain how we can know so much about cost-effective solutions, yet do so little. He suggests it’s time for cooperation among responsible energy producers and leading conservation organizations to simply rank companies on a true green scale and share these rankings with energy investment advisers, providing incentives for progress before it’s too late.

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.

Bat Knowledge Shared at the Vatican

 

Bat Knowledge Shared at the Vatican

Merlin was invited to participate in a roundtable discussion of Pope Francis’ Encyclical, “On Care for Our Common Home,” at the Vatican, on November 2. The meeting was hosted by the Pontifical Academy of Sciences, the Renewable and Appropriate Energy Lab of University of California, Berkeley and REIL, an interdisciplinary experts group.  The purpose was to extend the influence of this historic document promoting care of the environment. Thirty leaders from various fields were invited, including law, policy, finance, science, and religion.  The goal was to collaborate in promoting care of nature as essential to human wellbeing.  Merlin presented his experiences documenting values of protecting even such traditionally unpopular animals as bats, and benefited from lively discussions.

Algerian Bat Group Workshop Success

Les Chauves Souris D’algerie, ALGERIAN BAT GROUP recently held a bat workshop in Algeria, hosted by Professor Mourad Ahmim of the University of Bejaia. The workshop focused on the importance of bats and their impact on the national economy.

Merlin was asked to provide this 8-minute video introduction for workshop participants, giving them an overview of bat values and exhorting them to protect the bats of Algeria.

 

The workshop resulted in the first protection of a cave in Aokas, Algeria. The Cave of Aokas is now officially protected by a communal decree in memory of a former leader in European bat conservation, and much valued friend of Merlin’s, the late Professor Jiri Gaisler who discovered the cave and first studied its bats.

The Power of Bat Photos

img_8174

Stellaluna was brilliantly written and beautifully illustrated by one of our first Bat Fans, Janell Cannon. It’s the story of a baby fruit bat who gets separated from its mother. Since publication in 1993 this book has been translated into 30 languages. Stellaluna is a classic that significantly helped to endear kids, big and small, to if not love bats, at least appreciate them better, much the same as Merlin’s photographs.

 

In fact, Janell credits Merlin’s 1986 National Geographic article “Gentle Flyers of the African Night,” about epauletted fruit bats, for inspiring Stellaluna.

Janell recently emailed Merlin to share one of her community presentations, explaining how much she appreciated free use of his website photos. We love, love, love this kind of feedback! It Illustrates one of the many ways our website photos are making a difference for bats. As Bat Fan numbers grow, we’re happy to see the wide variety of creative uses individuals and institutions are making of our website gallery. Please share with us how you’re using our photos in your corner of the world to make it better for bats and people. (more…)
