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.

BAT FLASH! Countering Irresponsible Speculation that Threatens both Bats and Public Health

What’s going on?
The October 26, 2016 issue of ScienceDaily published an especially misleading story that poses a direct threat to both bats and public health. In this story, a fragment of an influenza A-like virus was discovered in a Latin American fruit-eating bat. The initial conclusion was that it posed “little, if any, pandemic threat to humans.”

A little yellow-shouldered bat (Sturnira lilium), an invaluable seed disperser, now prematurely speculated to be dangerous.

A team of lab scientists then used this new influenza-like material to bio-engineer a new influenza virus. To do this, they analyzed cells from over 30 different viral species for their capacity to become hosts. Then the cell that was most susceptible to the engineered virus was tested and found capable of infecting a variety of cells, including those of humans.

The resulting publication ends with this self-serving justification. “Bats are natural hosts for several highly pathogenic viruses. In the past, Ebola and rabies virus were repeatedly transmitted from bats to humans and caused deadly diseases. The new observation that human cells can be infected with bat influenza A-like viruses is a hint that these viruses could also potentially be transmitted to humans. Although there is no evidence yet for such transmissions, the new findings are a wake-up call for more research.”

The claim that Ebola has been repeatedly transmitted from bats to humans is false, completely lacking in scientific documentation, and the authors fail to admit that bat-transmitted rabies is one of our planet’s rarest human disease threats. It’s time to focus on real threats, like cancer and obesity. (more…)

BAT FLASH! Countering Delta Airlines Promotion of Bat-Eating

What’s Going On?
In its October 2016 issue, Sky Delta, Delta Airlines in-flight magazine, published a particularly offensive article titled Dare-to-Eat-Foods, sub-headed “Looking to up your culinary fear factor? Give one of these five uncommon-in-the-U.S. items a try,” by  Andrew Zimmern. The article recommends hunting and eating bats, animals that are being over-hunted to the verge of extinction, some having already become extinct due to too many being eaten.

What To Do
Please contact their editorial department (click here) and let them know that you strongly disapprove of their story promoting bat-eating, that most species being eaten are already in alarming decline, some already extinct from too many having been eaten.

What are Friends For?
Reinforcement! So, use them. Talk about it. Tweet about it. Tell all your pals. The bigger our voice, the bigger our muscles!

Until next time, Bat Fan…Thanks for being there!

Progress for bats via New Scientist – a call to action! 11/5/15

Lasionycteris noctivagans, U.S.In its February 8, 2014 issue, New Scientist published one of the worst scare stories ever titled, Contagion: Hordes of deadly diseases are lurking in bats and sometimes jumping to people. Can we prevent a major pandemic, asks Carrie Arnold.” Merlin and leading colleagues wrote rebuttals, and we asked our Bat Fan friends to join in the protest. Now we’re asking just the opposite!

Please thank them for much appreciated progress (no need to mention the past, just thanks for recently positive portrayals). Leave your comments in the Message Box, selecting Editorial/Content.

In their February 18, 2015 issue New Scientist collaborated with Merlin to publish a story on woolly bats living in pitcher plants that stated, “Contrary to common misconceptions, bats in general are gentle, highly intelligent and trainable.” On October 14, 2015 they published an extensive review of Merlin’s new book, The Secret Lives of Bats that included a strong presentation of bat values, debunked needless fears and showcased 11 portraits of cute bats.

We deeply appreciate all our colleagues and Bat Fans who are participating in making so much progress possible. Together, we can indeed change the future!
