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
If 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.

Freshwater jellyfish: Here one year, gone the next.
KNOXVILLE — Paddling along the still water of Mead’s Quarry Lake you notice the air bubbles created by your oars. They are all around your canoe near the surface.
It’s a hot early September afternoon and the nearly transparent bubbles seem to take on a life of their own. You slow to watch and yes, they undulate, rising and falling in the pristine water of the abandoned marble quarry.
Air bubbles do not undulate!
Taking a clear plastic cup, you lean over the gunwale and scoop up one of the penny-sized bubbles to get a closer look.
Tentacles? Air bubbles do not have tentacles. What you are looking at is a freshwater jellyfish and the heat of late summer is its mating season. It’s a blossom of jellyfish as hundreds gather together near the water’s surface. They are commonly known as peach blossom jellyfish.

GATLINBURG — Great Smoky Mountains National Park is celebrating the success of a community science project led by nonprofit partner Discover Life in America (DLiA) called Smokies Most Wanted. The initiative encourages visitors to record life they find in the park through the iNaturalist nature app. DLiA and the park use these data points to map species range, track exotic species, and even discover new kinds of life in the park.
“iNaturalist usage in the Smokies has skyrocketed from just four users in 2011, to 3,800 in 2020, to now more than 7,100 users,” said Will Kuhn, DLIA’s director of science and research.
In August, the project reached a milestone, surpassing 100,000 records of insects, plants, fungi, and other Smokies life submitted through the app. Among them are 92 new species not previously seen in the park.
Smokies researchers make a formal acquaintance with a familiar salamander
Great news from the Smokies via Instagram!
The “salamander capital of the world” just gained a new member! Meet our 31st species: the Cherokee black-bellied salamander, or Desmognathus gvnigeusgwotli. Its species name means “black belly” in the Cherokee language. Scientists used genetics to find out that it is different from the other black-bellied salamander in the park.
Dramatic monarch declines mean the bell tolls for we
KNOXVILLE — Monarch butterflies are ephemeral by nature. The orange and black dalliances that flitter through our lives, our yards, and our countryside like motes of dust are here one minute and gone the next. We pause for a few seconds to watch the “flutter-bys” and then move on.
For about all of the Lepidopteran family, where they come from, where they go, their raison d'être, we don’t ask. They are winged wisps that pass through our busy lives. But that is not true with this orange and black butterfly, named to honor King William III of England, the Prince of Orange. But two people did ask.
Norah and Fred Urquhart lived in Southern Canada and in the late 1930s they noticed that the monarch butterflies seemed to all be fluttering south this time of the year. Could they possibly be migrating and if so, where did they go? The notion that a butterfly might migrate south for the winter seemed hard to fathom. Yes, broad-winged hawks migrate. But a flimsy butterfly?

Discovery of ancient ambush predator is one of few large carnivores found at East Tennessee paleontological site
JOHNSON CITY — Overseen by the Don Sundquist Center of Excellence in Paleontology at East Tennessee State University, researchers have studied the Gray Fossil Site for over 20 years. They have identified many extinct animal and plant species of the Pliocene epoch that lived there some 5 million years ago. While large herbivores are well known from the site, large predators are relatively uncommon, so far including only alligators and scarce remains of at least one sabertooth cat.
Now, there’s a new predator on the scene.
A recent study published in the Journal of Paleontology describes a single right humerus (upper arm bone) of an animal named Borophagus, a member of an extinct group more commonly called bone-crushing dogs. The animal is so named for its powerful teeth and jaws. This is the first evidence of any animals in the dog family from the Gray Fossil Site.
The research was conducted by Emily Bōgner, a doctoral student at the University of California, Berkeley, and alumnus of ETSU’s paleontology master’s program, and Dr. Joshua Samuels, associate professor in the ETSU Department of Geosciences and curator at the Gray Fossil Site and Museum.
Charles Henry Turner concluded that bees can perceive time and develop new feeding habits in response
This story was originally published by The Conversation. Edward D. Melillo is a professor of history and environmental studies at Amherst College.
On a crisp autumn morning in 1908, an elegantly dressed African American man strode back and forth among the pin oaks, magnolias and silver maples of O’Fallon Park in St. Louis, Missouri. After placing a dozen dishes filled with strawberry jam atop several picnic tables, biologist Charles Henry Turner retreated to a nearby bench, notebook and pencil at the ready.
Following a midmorning break for tea and toast (topped with strawberry jam, of course), Turner returned to his outdoor experiment. At noon and again at dusk, he placed jam-filled dishes on the park tables. As he discovered, honeybees (Apis mellifera) were reliable breakfast, lunch and dinner visitors to the sugary buffet. After a few days, Turner stopped offering jam at midday and sunset, and presented the treats only at dawn. Initially, the bees continued appearing at all three times. Soon, however, they changed their arrival patterns, visiting the picnic tables only in the mornings.

Smokies officials say euthanized bear was overweight and seeking human food
GATLINBURG — Great Smoky Mountains National Park wildlife biologists and park rangers responded to Elkmont Campground on Sunday (June 12) after a peculiarly large black bear injured a toddler and her mother sleeping in a tent.
Wildlife biologists captured the responsible bear, and it was euthanized Monday, June 13, according to a news release from the park service.
“The bear weighed approximately 350 pounds, which is not standard for this time of year, suggesting the bear had previous and likely consistent access to non-natural food sources,” said Lisa McInnis, resource management chief.
Please don’t feed or get attacked by the animals

Millions of Americans enjoy observing and photographing wildlife near their homes or on trips. But when people get too close to wild animals, they risk serious injury or even death. It happens regularly, despite the threat of jail time and thousands of dollars in fines.
These four articles from The Conversation’s archive offer insights into how wild animals view humans and how our presence affects nearby animals and birds — plus a scientist’s perspective on what’s wrong with wildlife selfies.
Please don’t wage chemical warfare on these busy bees
KNOXVILLE — Old George Harvey lived two houses upstream from where I grew up on Baskins Creek in Gatlinburg. He had a strange obsession. Using empty jars, Old George would catch bees he found on the flowers and gardens around his house, screw on the lid and line the jars up on a ledge inside his screened-in porch. He’d then watch the bees die.
We kids thought it was odd and cruel. We’d plot slipping into his porch and freeing all the bees like Elliot freed the frogs from the classroom in the movie “E.T. The Extra-Terrestrial.”
