Why Bats Are Ecological Superheroes

Why Bats Are Ecological Superheroes


Bats are generally feared and significantly misunderstood. They’ve been significantly vilified within the wake of the COVID-19 pandemic, as many are falsely pushing the narrative that bats, and the sale of bats and different animals in moist markets, are guilty for the outbreak. We now have proof that’s merely not true. For extra info, remember to try tomorrow’s interview with virologist and molecular biologist Jonathan Latham, Ph.D.

In that interview, he presents proof exhibiting SARS-CoV-2 is extremely unlikely to have a pure origin, and stresses that we should not blame the wildlife commerce. It’s merely a ruse to cowl up compelling proof exhibiting it’s a lab-created virus that in some way escaped the confines of the laboratory.

So, please, depart bats alone, each figuratively and actually. Keep away from them, don’t eat them, don’t maintain them — and let scientists know we don’t want them to reap them for culturing and manufacturing new viruses.

What many individuals do not realize is that bats serve an necessary function, each to people and the setting. Bats are ecological superheroes that pollinate lots of our favourite meals. In addition they feed on agricultural pests that injury meals crops, saving farmers tons of of hundreds (if not tens of millions) of {dollars} every year.

The featured movie, “Rising a Greener World: Bats — Unsung Heroes,” explores the advantages bats have on the environment, their position in meals manufacturing, and what some scientists are doing to guard this necessary species.

The movie begins out in San Antonio, Texas, at Bracken Cave, a significant vacationer attraction that’s dwelling to the world’s largest bat colony. The cave supplies shelter for about 15 to 20 million Mexican free-tailed bats, based on the movie. Every night time at sundown in the course of the hotter months, the bats gracefully fly out of the collapse lots to start their nightly hunt.

Bracken Cave was bought by Bat Conservation Worldwide (BCI) in 1991. It now owns almost 1,500 acres of former ranchland surrounding the cave, which is within the strategy of being restored to its pure state.

The land misplaced a few of its unique plant and animal variety when it was being utilized for different functions resembling ranching. However due to the conservation work executed by BCI, the realm is now additionally dwelling to many chicken species, together with endangered golden-cheeked warblers.1

Bats Are the Solely True Flying Mammal

Within the movie, Fran Hutchins, director of Bracken Cave Protect, reveals that bats are the one true flying mammal. Mexican free-tailed bats weigh simply half an oz., or the equal of holding 50 cents in your hand, says Hutchins.

Regardless of being in the identical genetic class as people, bats are sometimes lumped in with animals like snakes and sharks, a few of the creatures we concern essentially the most. However when you begin to take a better have a look at bats and their distinctive habits, it is clear there may be nothing to concern about these helpful animals.

There are numerous enjoyable details about bats it’s possible you’ll not know. For instance, regardless of what you might have heard, bats are usually not blind. They’ll see very effectively. In addition they have wonderful flying skills and a formidable vary of movement.

Bats can fly as much as 50 to 60 miles per hour, and journey distances of as much as 30 to 50 miles in radius earlier than returning again to their dwelling. Bats are extra maneuverable than birds. They use a mix of echolocation and sense receptors that permit them to simply navigate via the night time sky.

Their echolocation skills work by emitting a sound out of their mouth, which bounces off an object. When it returns, it’s obtained and processed by their ears and different facial options. This echolocation method is what helps bats hunt for meals.

Bats emit sounds slowly and repetitively, as they navigate via the setting. Nonetheless, when bats dwelling in on an insect, the sound will increase in frequency proper up till they attain their prey. They then use their wings to grab up the insect earlier than consuming it.

With out Bats, We Would not Have Tequila

Bats as a species are extremely various. There are an estimated 1,400 species of bats worldwide. They reside on varied components of the planet and vary in dimension. For instance, the Kitti’s hog-nosed bat, additionally referred to as the Bumblebee Bat, weighs lower than a penny, making it the world’s smallest mammal subsequent to the flying fox, based on the U.S. Division of the Inside.2

Whereas bats are professional hunters, they’re additionally necessary pollinators. Identical to birds, butterflies and bees, bats pollinate many necessary meals crops, however as a result of they achieve this at night time underneath the duvet of darkness, they do not get as a lot recognition.

Greater than 300 species of food-producing crops rely on bats for pollination. A few of these embody guavas, bananas, mangos, figs, dates, cashews and peaches. Bats additionally pollinate different flowering crops together with agave, the important thing ingredient in tequila.

With out bats, we’d not have tequila. Bats are the primary pollinator of agave, which blooms at night time in Desert Southwest, based on the movie. Agave crops are a significant meals supply for bats. Sadly, in an effort to maximise income, some big-time tequila producers are reducing down agave stalks earlier than they’ve an opportunity to flower.

This can be a large downside for bats. Fortunately, some producers are being a bit extra accountable in the best way they develop agave and produce tequila. They’re permitting a few of the agave crops to flower in order that bats have a meals supply alongside their migratory pathway.

Some sustainable tequila producers have even branded their merchandise “bat-friendly.” Bat-friendly tequila will be discovered at varied specialty bars and eating places across the U.S., together with San Antonio’s Esquire Tavern, which serves a spicy cocktail referred to as the “Batman of Mexico.” It is made with Tequila Ocho, which will be discovered at some U.S. liquor shops for about $45 a bottle.3

Austin’s South Congress Bridge Is Residence to 1.5 Million Bats

The following cease within the movie is Austin, Texas. The capital metropolis is finest identified for its laid-back ambiance, tasty tacos and its “Preserve Austin Bizarre” slogan. It is also identified for its bats, which reside underneath the South Congress Bridge.

The bridge was constructed utilizing cast-in-place concrete to expedite the development. Little did they know the design would create tiny areas beneath the bridge that function the proper bat home.

An estimated 1.5 million Mexican free-tailed bats migrate north to Austin and name the bridge dwelling in the course of the hotter months of March via October.4 Like they do on the Bracken Cave, tens of millions of bats descend from underneath the bridge at sundown, swirling in a mesmerizing tornado-like form.

Mylea Bayless, senior director of Networks & Partnerships Bat Conservation Worldwide, says within the movie that the bats keep collectively like a faculty of fish in an effort to keep away from predators. They fly downstream alongside the tree line out to the corn and cotton fields the place they primarily feed on agricultural pests. The viewing attracts hundreds of people that line up alongside the bridge every night time, ready to observe the bats.

Bats Save Natural Pecan Farm in Texas

Whereas bats get quite a lot of recognition in a few of Texas’ largest cities, they’re equally as honored within the Texas Hill Nation. The featured movie visits John Byrd, a pecan orchardist and proprietor of King’s Crossing Farm, an natural farm situated in San Saba, Texas.

The 109-acre farm was established by Byrd’s grandfather in 1944, who was additionally one of many founders of the Texas Pecan Growers Affiliation. Texas is one in every of few states the place pecans are indigenous.5

Byrd’s 1,200 pecan timber are a part of the household legacy. However they’re additionally an attraction for pests. Within the movie, Byrd explains that the most important pest risk to his pecans is the casebearer moth, which might lay 100 eggs at a time. Every egg makes a bit caterpillar that goes right into a pecan nut and kills it.

If all 100 eggs are in a position to efficiently make their approach right into a cluster of pecans, they’ll kill 100 pecans, says Byrd. That is about 1 pound, which prices about $1.50. So, for each moth, the farm stands to lose $1.50. Byrd makes use of natural rising strategies on his farm,6 which suggests pesticides are usually not an possibility for coping with the moths.

Bats Are Nature’s Exterminator

“I’ve 400-year-old pecan timber which have been doing effectively with out chemical substances or folks, and so they produce pecans,” he says. “There’s a option to do it with out pesticides. I wish to promote life, not loss of life, in my orchards.”

In an effort to take care of the moths naturally, Byrd began constructing bat homes in hopes of attracting the animals to his orchard. He began out with a small bat home, which was shortly full of bats. He then constructed a bat home 3 times the scale as the primary. It too crammed nearly instantly with bats.

Lastly, he constructed one of many largest bat homes obtainable, which might maintain as much as 30,000 bats. It took some time longer, however it too, finally grew to become full. Byrd says the big bat home now holds about 20,000 bats. They’re doing their job, too, he says. DNA evaluation discovered the bats have been actually consuming the casebearer moths. Byrd now has fewer pests and extra pecans.

Bats are one in every of nature’s finest exterminators. The bats that reside in Bracken Cave outdoors of San Antonio eat an estimated 147 tons of bugs per night time, most of that are agricultural pests, based on the movie. In consequence, bats save farmers within the Texas Hill County about $750,000 a 12 months in crop injury and pesticides. Within the U.S, bats are estimated to save lots of farmers wherever from $3.7 billion to $53 billion per 12 months.7

Bats Are Threatened Worldwide

Regardless of their significance, bats worldwide are in danger for plenty of causes together with habitat loss, local weather change, illness, deforestation and the bushmeat commerce.8 Scientists report a lack of 50% of the world’s bugs since 1970,9 a disastrous estimation that is predicted to have an effect on all varieties of wildlife, together with bats.

One other main risk to bats is white-nose syndrome, a fungal illness that eats away the tissue of North American bats. The pathogen will get its identify from the looks of a fuzzy white materials that grows on the bats’ snout, ears, wings or ft.

The pathogen prefers chilly temperatures, which suggests bats are most prone when they’re hibernating and their physique temperature is decreased, explains Chris Cornelison, Ph.D., a analysis assistant professor at Kennesaw State College.

“From a wildlife illness standpoint, we’re experiencing a few of the most precipitous, severe-associated declines of wildlife which have ever been recorded,” says Cornelison within the movie. “In a few of the worst instances, we have noticed over 99% declines in these populations.”

The excellent news is that scientists are working arduous on options. One answer includes the usage of naturally occurring VOCs that can be utilized along side a nebulizer to supply an aerosol volatilized fuel to spray on the bats. This represses the expansion of the fungus whereas they hibernate.

That is generally difficult, as bats hibernate in caves which can be inaccessible to people. For instance, on the Black Diamond Tunnel in North Georgia, scientists needed to develop the infrastructure to mount a nebulizer on a ship in an effort to ship it autonomously into the cave to distribute the antifungal fuel.
