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

Turn Your LEGO Bricks Into a Drone With the Flybrix Drone Kit

Now more than ever, it’s important to have a good hobby. Of course, a lot of people—maybe even you—have been obsessed with learning TikTok dances and baking sourdough bread for the last few months, but those hobbies can wear out their welcome pretty fast. So if you or someone you love is looking for something that’s a little more intellectually stimulating, you need to check out the Flybrix LEGO drone kit from Fat Brain Toys.

What is a Flybrix LEGO Drone Kit?

The Flybrix drone kit lets you build your own drones out of LEGO bricks and fly them around your house using your smartphone as a remote control (via Bluetooth). The kit itself comes with absolutely everything you need to start flying almost immediately, including a bag of 56-plus LEGO bricks, a LEGO figure pilot, eight quick-connect motors, eight propellers, a propeller wrench, a pre-programmed Flybrix flight board PCB, a USB data cord, a LiPo battery, and a USB LiPo battery charger. All you’ll have to do is download the Flybrix Configuration Software, the Bluetooth Flight Control App, and access online instructions and tutorials.

Experiment with your own designs.

The Flybrix LEGO drone kit is specifically designed to promote exploration and experimentation. All the components are tough and can totally withstand a few crash landings, so you can build and rebuild your own drones until you come up with the perfect design. Then you can do it all again. Try different motor arrangements, add your own LEGO bricks, experiment with different shapes—this kit is a wannabe engineer’s dream.

For the more advanced STEM learners out there, Flybrix lets you experiment with coding and block-based coding. It uses an arduino-based hackable circuit board, and the Flybrix app has advanced features that let you try your hand at software design.

Who is the Flybrix LEGO Drone Kit for?

Flybrix is a really fun way to introduce a number of core STEM concepts, which makes it ideal for kids—and technically, that’s who it was designed for. But because engineering and coding can get a little complicated, the recommended age for independent experimentation is 13 and up. However, kids younger than 13 can certainly work on Flybrix drones with the help of their parents. In fact, it actually makes a fantastic family hobby.

A Prehistoric Great White Shark Nursery Has Been Discovered in Chile

Great white sharks (Carcharodon carcharias) may be one of the most formidable and frightening apex predators on the planet today, but life for them isn’t as easy as horror movies would suggest. Due to a slow growth rate and the fact that they produce few offspring, the species is listed as vulnerable to extinction.

There is a way these sharks ensure survival, and that is by creating nurseries—a designated place where great white shark babies (called pups) are protected from other predators. Now, researchers at the University of Vienna and colleagues have discovered these nurseries occurred in prehistoric times.

In a study published in the journal Scientific Reports, Jamie A. Villafaña from the university’s Institute of Palaeontology describes a fossilized nursery found in Coquimbo, Chile. Researchers were examining a collection of fossilized great white shark teeth between 5 and 2 million years old along the Pacific coast of Chile and Peru when they noticed a disproportionate number of young shark teeth in Coquimbo. There was also a total lack of sexually mature animals' teeth, which suggests the site was used primarily by pups and juveniles as a nursery.

Though modern great whites are known to guard their young in designated areas, the researchers say this is the first example of a paleo-nursery. Because the climate was much warmer when the paleo-nursery was in use, the researchers think these protective environments can deepen our understanding of how great white sharks can survive global warming trends.
