34 species, over a third of Panama’s 100+ bat species have been captured by our intrepid bat enthusiasts in just three nights!
Merlin and Daniel Hargreaves, co-founder of Trinibats, have teamed up to co-lead two weeks of bat workshops at the Cocobolo Nature Reserve in Panama. The reserve is over 1,000 acres located about halfway between the Pacific and the Caribbean on the narrow Isthmus of Panama, about 35 miles wide.

While the public continues to be pummeled with scary claims of dire threats of disease from bats, Merlin has been rallying crucial leadership collaboration from within the international research community. In September, he provided an hour lecture, followed by an enthusiastic hour-long discussion, for virologists and epidemiologists at Brazil’s Oswaldo Cruz Foundation in Rio de Janeiro. And several days later he provided the keynote address for a joint annual meeting of Brazil’s Bat and Mammal Societies, with special attention to helping conservation-minded students.
In November, Merlin presented the inaugural address for a joint meeting of the Biology and Ecology Societies of Chile. A key concern there involved how to prevent bat killing due to irresponsible warnings of disease. Amazingly, even in a country where only one person in all history had died of a bat disease (rabies), fear of bats due to exaggerated media stories reportedly is posing a serious threat to conservation progress. Concerned attendees at the conference were delighted to learn of our disease resources and other information and photos available for their use. They were also most appreciative for advice on expanding threats from wind energy and pesticides. Merlin additionally agreed to provide photos for the bat section of a new book on Chilean mammals.
We first met Alexis Valentine and her mother Amy, when Merlin spoke at an annual Discover Life in America conference in Gatlinburg, Tennessee in 2014. We’ve kept in touch ever since, encouraging her research and competition in local and regional science fairs. We were thrilled to hear that she had been awarded a full scholarship to represent the U.S. at the 14th Annual Jr. Foresters Science/Research Competition in Moscow, Russia. Forty-five participants from 28 countries and five continents presented projects, September 2-10 and Alexis won second place out of 40 awards. At 15, she was the youngest competitor to win an award, and also was the highest ranking American contestant in the competition’s history.
Last week, she did a fine job of presenting her research on the impact of white-nose syndrome on bats in the Great Smoky Mountains National Park at the annual teacher’s workshop held in conjunction with the NASBR 47th Annual Symposium on Bat Research in Knoxville, Tennessee.
Knowing Alexis had long dreamed of owning her own ultrasonic bat detectors for her research and public presentations, Merlin took the opportunity to introduce her to Ian Agranat, President of Wildlife Acoustics, the worlds’ largest producer of wildlife monitoring devices. Their Echo Meter Touch 2 Pro bat detector is one on Merlin’s favorite tools for introducing the public to bats, and he was delighted when Ian made Alexis’ long-time dream of owning her own equipment come true through his generous gifts which covered all her needs.
Keep it up, BatGirl, we’re proud of you!
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.

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.
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.

Book Review: Conservation and Ecology of Pennsylvania’s Bats
By Merlin Tuttle
Conservation and Ecology of Pennsylvania’s Bats, edited by C.M. Butchkoski, D.M. Reeder, G.G. Turner, and H.P. Whidden. 2017, is a publication of the Pennsylvania Academy of Science. Twenty-eight contributors cover a wide variety of conservation-relevant topics. It summarizes the key ecological and economic roles of bats and traces the history of bat research and conservation efforts in Pennsylvania, which has one of America’s finest records of conserving bats.
A Wind Energy Voluntary Cooperation Agreement is reported to have gained beneficial results. However, the environmental review process does not cover most of the state’s species. And at least one of the state’s largest companies has refused to participate. The potentially serious, yet inadequately documented wind energy impacts on bats remain as unresolved threats. (more…)

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.
