Meet Gracie: The Resident 'Bark Ranger' at Montana's Glacier National Park

Gracie isn't like the other park rangers at Glacier National Park in Montana: She’s not afraid to run after bighorn sheep and mountain goats in order to keep them at a safe distance from visitors. And while she doesn’t earn a salary, she’s content to work for belly rubs.

That’s because Gracie is a trained border collie who became the first employee-owned dog to become a “bark ranger” at a U.S. national park. She was accepted into Glacier’s wildlife shepherding program in July 2016 and has been protecting both humans and wildlife alike ever since.

One of Gracie's main duties is to keep sheep and goats away from areas with high foot traffic, like the Logan Pass parking lot. Through habituation, many of the park’s native species have begun to feel comfortable around humans, and sometimes even approach them. This is problematic for a couple of reasons.

“When closely approached or provided with human food, bighorn sheep and mountain goats can become aggressive; each has the ability to kick, bite, gore, or trample when feeling threatened,” the National Park Service (NPS) writes on its website. “This can cause injury—or in rare cases, death—to people and can cause the animal to be lethally removed from the population.”

In the winter, Gracie also helps shepherd deer out of highly populated areas in an effort to keep predators—namely mountain lions—away from people. Gracie completed a 10-week training program in Florence, Montana, where she learned how to control her direction and speed. She also knows when to retreat at the command of her owner, Mark Biel, who works as the park's natural resources program manager.

Gracie’s hard work has not gone unnoticed either. Her Instagram account, which chronicles the life of a #WorkingDog, has more than 17,000 followers. Check out some of the photos and videos below to see this very good girl in action.

Every time Gracie moves wildlife, Ranger Mark records how many animals were moved, how long it took to move them, where they went, and how long they stayed out of the area. This helps us evaluate the effectiveness of the program and learn about wildlife habits. The data show that in the park headquarters area, the deer have four established “escape routes” they favor when heading into the woods. Watch as this deer stops to decide which way to go, then heads to the left, toward the woods and one of those routes. Turning to the right would have taken it away from Gracie, but further into the housing area. This is an example of the program working as it’s intended. When pressured from a distance, the deer decides that the more comfortable place to be is in the woods, instead of further inside the populated area. 🐾🦌 #parkscience #barkrangergracie #barkranger #whitetail #keepwildlifewild​ @glaciernps @glacierconservancy @wind_river_bear_institute #workingbordercollie #workingdogsofig #glaciernationalpark #glacier

Meet LiLou: The World's First Airport Therapy Pig

There's a new reason to get to the airport early—you might run into a therapy pig who's there to make your trip a little easier. As Reuters reports, LiLou the Juliana pig is a member of San Francisco International Airport's "Wag Brigade," a therapy animal program designed to ease stress and anxiety in travelers.

Aside from her snout and potbelly, LiLou can be recognized by her captain's hat and red "hoof" polish. She spends the day with guests who are happy to take a break from the pressures of traveling. She might comfort them by posing for a selfie, playing a song on her toy keyboard, or offering them a head to pet.

After bringing joy to people's day, LiLou goes home to her San Francisco apartment where she lives with her owner, Tatyana Danilova. In her free time, she goes on daily walks and snacks on organic vegetables. She even has her own Instagram account.

Airports around the world are embracing the benefits therapy animals can bring to customers. The Wag Brigade program at San Francisco includes a number of dogs, and earlier this year, the Aberdeen Airport in Scotland debuted its own "canine crew" of dogs trained to make travelers feel safe and happy. Therapy miniature horses have even been used at an airport in Kentucky. According to the San Francisco Airport, LiLiou is the world's first airport therapy pig.

Sssspectacular: Tree Snakes in Australia Can Actually Jump

Ophidiophobia, or fear of snakes, is common among humans. We avoid snakes in the wild, have nightmares about snakes at night, and recoil at snakes on television. We might even be born with the aversion. When researchers showed babies photos of snakes and spiders, their tiny pupils dilated, indicating an arousal response to these ancestral threats.

If you really want to scare a baby, show them footage of an Australian tree snake. Thanks to researchers at Virginia Tech, we now know these non-venomous snakes of the genus Dendrelaphis can become airborne, propelling themselves around treetops like sentient Silly String.

That’s Dendrelaphis pictus, which was caught zipping through the air in 2010. After looking at footage previously filmed by her advisor Jake Socha, Virginia Tech Ph.D. candidate Michelle Graham headed for Australia and built a kind of American Ninja Warrior course for snakes out of PVC piping and tree branches. Graham observed that the snakes tend to spot their landing target, then spring upward. The momentum gets them across gaps that would otherwise not be practical to cross.

Graham next plans to investigate why snakes feel compelled to jump. They might feel a need to escape, or continue moving, or do it because they can. Two scientific papers due in 2020 could provide answers.

Dendrelaphis isn’t the only kind of snake with propulsive capabilities. The Chrysopelea genus includes five species found in Southeast Asia and China, among other places, that can glide through the air.
