New film highlights importance of rattlesnakes to the Southern Appalachian environment

Timber rattlesnakes have been demonized for centuries, perhaps to the extent humans are incapable of understanding the snake’s importance to the world. 

The Orianne Society determined the apex predator is of vital importance to the Appalachian region, yet the snake is facing tremendous challenges to its survival.

The film “Rattled: Conserving Rattlesnakes in Appalachia — A Conservation Documentary.” introduced those sentiments when it premiered in Atlanta and other locations in Georgia and North Carolina.

Researcher Dr. Chris Jenkins, CEO of the Orianne Society, is behind the story for the film.

Jenkins said timber rattlesnakes are declining across their range from Maine to Texas. Wildlife biologists attribute the decline to “low recruitment,” meaning reproductive rates that fail to replace their population.

A female rattlesnake may live 50 years, though most live only to 30 or 40. Maturity usually requires 10 years, and snakes may only produce young every other year. The broods are small and the mortality rate is high among young snakes. Rattlesnakes that encounter humans are often killed, leaving no successors.

What city birds around the world have in common

This story was originally published by The Revelator.

Why do some bird species seem to flourish alongside humans, eating our crumbs and nesting in our backyards, while others prefer to live as far as possible from dense human populations?

Monte Neate-Clegg began to ponder the question while attending the American Ornithological Society’s 2019 conference in Anchorage, Alaska. “I was staying at an AirBnB and two of the birds I wanted to see in Anchorage, white-winged crossbills and boreal chickadees, were just in the yard,” said Neate-Clegg, at the time a Ph.D. student at the University of Utah. Although new and beautiful to him, the species are common in Anchorage and so omnipresent they’re typically ignored by residents.

“I started thinking, what is it that makes these ‘trash birds’ here, and not elsewhere?”

Neate-Clegg sounds sheepish about using the pejorative-sounding term “trash bird,” but it’s a phrase commonly used by birdwatchers to refer to species ubiquitous to a given location they cease to become interesting and can become irritating. Classic examples include pigeons in city centers and snack-stealing gulls on beaches.

One man’s trash bird is another’s research query. Neate-Clegg wondered if specific traits make certain species more able to thrive in cities around the world. After joining ornithologist Morgan Tingley at his lab at UCLA as a postdoctoral researcher in 2021, he proposed a lab-wide project in an attempt to answer the question.

The research drew on data providing clues which may eventually reveal a roadmap making our cities more bird friendly.

TWRA wants you to help build research on USA’s second bird

NASHVILLE — Benjamin Franklin only joked (we think) about making the wild turkey the national bird, but this summer you can help Tennessee with research on the turkey’s national history and renaissance.

Turkeys and bald eagles both grace the state and Southeast and have a notably parallel history of climbing from dire straits nationwide. 

The bald eagle became the national symbol on the U.S. seal in 1782

Declaration of Independence signer Franklin said he would have preferred a different bird. While he may have been joking, he never lobbied for it publicly. His comments in a letter to his daughter, Sarah, have become infamous.

“For my own part I wish the bald eagle had not been chosen as the representative of our country. He is a bird of bad moral character. He does not get his living honestly. You may have seen him perched on some dead tree, where, too lazy to fish for himself, he watches the labour of the fishing hawk; and when that diligent bird has at length taken a fish, and is bearing it to his nest for the support of his mate and young ones, the bald eagle pursues him, and takes it from him … the turkey is in comparison a much more respectable bird, and withal a true original native of America.”

TDOT joins with Tennessee Aquarium to pollinate our pathways

CHATTANOOGA — With their distinctive orange and black patterns, gossamer wings and harrowing 3,000-mile migrations, few insects are as charismatic or beloved as the monarch butterfly. 

Just imagine how tragic it would be if they disappeared.

So it was with alarm in 2022 that the world received news that the International Union for Conservation of Nature (IUCN) had declared the monarch an endangered species, citing population numbers that had fallen 80 percent since the 1980s. 

Similar anxiety met reports in the mid-2000s of colony collapse disorder. This sudden phenomenon dramatically imperiled the survival of European honey bees, whose activity directly or indirectly affects roughly one of every three bites of food we eat, according to the U.S. Department of Agriculture.

Pollinators are undoubtedly critically important to plants and humans alike, whether they’re investigating our Irises, calling on our Columbine, or buzzing our Blueberry bushes. This week, June 19-25, the world celebrates Pollinator Week, which recognizes the wondrous, vital contributions of butterflies, bees, moths, bats, and other pollinators.

If you see this vanishing snake alert the state

Pine snake notice

Help TWRA save our pine snakes

NASHVILLE — If you see a vanishing northern pine snake, biologists with the Tennessee Wildlife Resources Agency (TWRA) want to know.

One subspecies of the pine snake, (Pituophis melanoleucus melanoleucus), lives in Tennessee. The snake is considered “threatened” by TWRA due to habitat loss and fragmentation, road mortality, and humans who kill the snakes because they mistake them for timber rattlesnakes.

Brian Flock, biodiversity coordinator for TWRA, said the reports will help the agency find out about the threatened snakes’ habitat and behavior.

“For years we’ve tried to find them. Because of their secretive nature, they’re hard to find,” he said. “We don’t know in Tennessee where they live, how they move around, those kinds of things.” He said they mostly seem to exist in West Tennessee but have been spotted as far east as Knoxville. TWRA, he said, may use the public’s information to add radio tracking devices to the snakes.

The State of Bats: Grim news for our winged mammals

Little Brown BatThe big brown bat feeds on beetles, flies, moths, and true bugs, which it catches and eats while in flight. It is widespread across the Southern Appalachians and forages for food by flying slow, straight courses over water, forest canopies, wooded clearings, and around city lights.  J. Scott Altenbach via Georgia Department of Natural Resources

North America’s first State of the Bats report gives a sobering outlook for the winged mammals. According to the North American Bat Conservation Alliance report:

  • More than half of the 154 known bat species on the continent could face severe population declines over the next 15 years.
  • During that time, up to 82 percent of bat species will be negatively affected by climate change, especially extreme drought and temperatures.
  • The scope and severity of threats — including habitat loss, wind turbines and the deadly bat disease white-nose syndrome — are increasing.

The news isn’t all bad. The report outlines ways to help and emphasizes the wide-ranging benefits of bats, from improving crop yields to eating insect pests. It also highlights the promise of focused, collaborative conservation efforts.

Case in point, the lesser long-nosed bat was once endangered in Mexico and the U.S. But thanks to international efforts, it is now delisted and recovered in both countries.

The North American Bat Conservation Alliance is another example. The coalition involving the U.S., Mexico and Canada created the 2023 State of the Bats report with Bat Conservation International and others.

“Bats face many challenges and the conservation landscape is increasingly complex,” said Dr. Jeremy Coleman, alliance co-chair and white-nose syndrome coordinator for the U.S. Fish and Wildlife Service. “While there is more to do, the level of international collaboration we have achieved for bat conservation in North America is a bright spot and a cause for optimism going forward.”

Researchers quantify the effects of feral hogs on Smokies salamander populations

GATLINBURG — A recent study investigating the relationship between Great Smoky Mountains National Park’s beloved salamanders and its hated hogs concluded that the rooting of feral pigs decreases the abundance and diversity of Smokies salamanders.

Alexander Funk of Eastern Kentucky University said the effects of feral hogs on salamanders from the family plethodontidae were mixed and varied depending on the season.

Generally, across seasons and especially in the summer, the hogs’ foraging seemed to hurt salamander abundance and diversity. Funk is a student under Eastern Kentucky University’s Director for the Division of Natural Areas Stephen Richter but had help from Benjamin Fitzpatrick of the University of Tennessee at Knoxville. The study involved Funk going out late at night on Balsam Mountain in the spring, summer and fall of 2022.

Foundational ecology moves from before times to nowadays in the Smokies

GATLINBURG — In the Middle Ages, salamanders were thought to come from fire. A log set on the hearth would send them scurrying out of the rotten wood, startling those who had gathered around for warmth. We now know that salamanders, of course, come from water — even the European fire salamander with its flame-like yellow markings.

Over the last 20 years of getting my boots soggy in Great Smoky Mountains National Park, I know these creatures to thrive in the clean, shallow streams and trickles of this temperate rainforest, where annual precipitation is higher than anywhere in the U.S. save for the Pacific Northwest.

One way to become acquainted with the park is through the water that veins through the hills and is transmuted into vapor that floats on the air in misty silence. After a rain, you can slake your thirst from the pools formed in the creases of broad rhododendron leaves. Sit by a shallow, fishless stream for long enough and you might spot the quick movement of a salamander tail, maybe a flash of orange or brown, or notice a tiny black amphibian face peeking out from behind a smooth stone in the creek.

Judge rules that Tennessee Wildlife Resources Agency grossly overstepped its bounds following citizen complaint

This story was originally published by Tennessee Lookout.

NASHVILLE — Holly Lamar, a master falconer and owner of a Nashville “bird experience” business, has a story to tell about each one of her 13 captive-bred birds of prey.

The story behind Faith, a 7-year-old peregrine falcon, is tied to a particularly rough patch for Lamar, who experienced success as a Grammy-nominated songwriter, then lost nearly everything. The 20-day-old chick arrived just after Lamar fell victim to a financial scam that wiped out earnings from her music career.

She picked the name “Faith” to symbolize the feelings of trust she was trying to regain in her life — and as a nod to Faith Hill, the country singer who recorded “Breathe,” a 1999 megahit co-written by Lamar. 

Faith, the falcon, is now dead — one of 13 falcons seized by officers with the Tennessee Wildlife Resources Agency in a sweeping August search of Lamar’s home and property that a Nashville judge later characterized as “egregious,” an “abuse of the law” and a violation of Lamar’s constitutional rights.

Beyond festivals, sandhill cranes pass through Southeast in increasing numbers

BIRCHWOOD — Every year in mid-January, a few thousand people gather here for The Sandhill Crane Festival because the cranes have returned. The community center at Birchwood is filled with vendors selling wildlife art or promoting conservation. The nearby Cherokee Removal Memorial at Blythe Ferry offers a chance to celebrate Cherokee culture and learn the story of indigenous people who were taken from their homes and sent on a long journey to Oklahoma.

Meanwhile, there are opportunities to see and appreciate these amazing birds through February in East Tennessee and beyond.

At least 20,000 cranes gather or pass through Hiwassee Wildlife Refuge, having come from their nesting grounds in southern Canada and the upper Midwest to winter here in the American South. Many spend the winter there, but some will continue southward to Okefenokee Swamp in Georgia and the Gulf Coast.

As yellow cardinals proliferate, are we watching evolution unfold in real time?

HARRIMAN — During the pandemic, when isolating at home became a necessity, birdwatching and bird feeders soared in popularity. Watching our avian friends come and go is entertaining, and sometimes quite surprising.

When it comes to songbirds, especially at this time of year, the northern cardinal is perhaps the most recognized and beloved.

It is the state bird of no less than seven states: Illinois, Indiana, Kentucky, North Carolina, Ohio, Virginia and West Virginia.

It’s also the nickname of more sports teams than any other icon. There are the St. Louis Cardinals in baseball, and the Arizona Cardinals in professional football. In the NCAA, there are the Louisville Cardinals and 17 other colleges that sport the red mascot, as well as a gaggle of high school teams across the country.

Since we were children, we have all known what a male northern cardinal looks like. He’s bright red. Right? Yes, unless he’s bright yellow!

Finding a golden treasure usually requires a long arduous quest through terra incognito.

Research from Kimberly Sheldon at the University of Tennessee suggests insect behavior is adjusting for climate change

The ConversationIf the TV series “Dirty Jobs” covered animals as well as humans, it would probably start with dung beetles. These hardworking critters are among the insect world’s most important recyclers. They eat and bury manure from many other species, recycling nutrients and improving soil as they go.

Dung beetles are found on every continent except Antarctica, in forests, grasslands, prairies and deserts. And now, like many other species, they are coping with the effects of climate change.

I am an ecologist who has spent nearly 20 years studying dung beetles. My research spans tropical and temperate ecosystems, and focuses on how these beneficial animals respond to temperature changes.

Bog turtles raised for resurrection at Zoo Knoxville’s ARC

KNOXVILLE — Zoo visitors might overlook the collection of critters behind a small, unremarkable window. But amid the showier gila monster, reticulated python, king cobra and Cuban crocodiles, there’s a regional species on the brink of extinction that’s worth a closer look.

Behind the glass, tiny juvenile bog turtles poke their heads out from underneath sphagnum moss at Zoo Knoxville’s Clayton Family Amphibian Reptile Conservatory (ARC).They are mostly brown, with splashes of gold on their heads. When they mature, they will move to the Bern Tryon Turtle Propagation Bog just outside. Eventually, the zoo will release the heartiest of the bunch. This process, called head-starting, involves raising the turtles from eggs and feeding them well in captivity so they’ll be bigger and have a better chance to survive after returning to the wild.

UT Arboretum event reminds us to love and care for the butterflies among us

OAK RIDGE — With an orange flutter, a cluster of painted lady butterflies took to the sky.

It was a timed release, coming toward the end of the seventh annual University of Tennessee Arboretum’s Butterfly Festival last month. 

Earlier, other live painted lady butterflies were available to watch in mesh tents. Visitors got a chance to touch Madagascar hissing cockroaches and look at preserved insect collections with butterflies and other creatures from around the world. Children ran around the event with butterfly face paint, butterfly masks and butterfly wings. But the event was also a chance to buy butterfly-friendly plants and learn about butterflies and their relationships with other species.
