The Amazing Story of 27-Year Old Grizzly Bear 399

The Amazing Story of Grizzly #399

When a grizzly bear appears in Wyoming's Grand Teton or Yellowstone National Park, traffic comes to a grinding halt. Hundreds of cars get stuck in a traffic jam that can go on for miles - adequately called a bear jam - and everyone's heart rate goes up in the hopes of spotting this legendary predator. Seeing a wild grizzly is the highlight of many family vacations.

Among the estimated 730 grizzlies that live in the Greater Yellowstone ecosystem, one has become nothing less than an international celebrity: a bear identified as "399," otherwise known as the Queen of the Tetons.

399 was born in the winter of 1996.  She was given her name, "number 399," in 2001 by the Interagency Grizzly Bear Study Team, group of scientists and biologists responsible for long-term monitoring and research efforts on grizzly bears in the Greater Yellowstone Ecosystem (GYE).  Seeing that grizzlies have an estimated life span in the wild of 20 to 25 years, 399 can be considered a senior citizen: she is set to turn 27 in a few days! (bear cubs get born typically in January) 
Will she make it through another cold Yellowstone winter? Or, will she defy all expectations and emerge from her winter den in the spring of 2023 with new cubs in tow?

It wouldn't be the first time grizzly 399 surprised the world.  In 2020, at the old age of 24, after a long and brutal winter during which the Greater Yellowstone Ecosystem received 11 feet of snow and temperatures dipped down to minus 25 F (minus 31 C), she emerged from her den with no less than four new cubs in tow! An impressive feat, especially since the federal Interagency Grizzly Bear Study Team had never seen a litter of four at 399's age.  But what's more: the oldest known grizzly in the area to have cubs was 27 years old, and that's the age 399 will be in 2023.


Why is Grizzly 399 so Famous?

Whereas a typical grizzly chooses to live its life in the back country, far away from human activity, 399 has chosen to spend at least part of her life being close to humans. Some believe this is a deliberate strategy to keep her cubs safe: 399, like some other grizzly sows in the area, raises her cubs near roadsides and developed areas to keep them safe from male grizzlies, who are known to kill cubs. Male grizzlies ("boars") kill cubs in order for the grizzly sow to stop lactating and go back into reproduction mode. That relative easy visibility near park roads makes her and similar bears nothing less than tourist and photographer magnets.

In her life span so far, she is believed to have produced at least 22 descendants, including the cubs that her offspring have birthed over the years. That's impressive were it not that this isn't as rosy as it sounds. About half of her offspring is believed dead. There is the sad story of her daughter, grizzly 615, who was shot by a poacher. Some have been killed by cars, like her only 2016 cub, "Snowy." Others still are believed to have been killed by male grizzlies. Did you know that an estimated 85% of grizzlies never make it to 399's age? All of this to say that life isn't easy and guaranteed, even when you're at the top of the food chain in the animal kingdom.


Grizzly 399, Celebrity Mother and Grandmother

Her most famous offspring is a grizzly sow identified by the federal Interagency Grizzly Bear Study Team as 610, is also regularly seen in Grand Teton National Park. Born as one of 399's triplets in 2006, grizzly 610 is currently caring for three cubs born in 2022 and, as if in a fairy tale, is actually close to her mother. In June of 2020, 399 with her four cubs and 610 with her -at the time - two cubs were seen meeting each other in Grand Teton National Park. Contrary to popular beliefs that grizzly sows with cubs are aggressive towards other adult bears, both bears recognized each other and the six cubs even played together.  In fact, back in 2011, when 399 had triplets and 610 had twins, 610 willingly adopted one of her mother's cubs: 610 ended up raising triplets while 399 raised her two remaining cubs!


399 guides her four cubs in the spring of 2022, shortly after coming out of hibernation.  The cubs were 2.5 years old this year and, shortly after, were 'kicked out' by 399 to live on their own.


Celebrity 399, Queen of the Tetons

Things occasionally get crazy during a bear jam. We all love to experience the bears (and other wildlife) but some of us seem to forget at times that these are in fact wild animals and that the National Park is not a petting zoo.  These bears are wild animals and are, at last check, stronger and faster than any human alive.

To keep everyone safe, since 2007, Grand Teton National Park enrolls a special group of volunteers called the "Grand Teton Wildlife Brigade." In fact, it was due to the popularity of grizzly 399 emerging from her den with three cubs back in 2007 that the brigade was formed. Their mission is to keep the wildlife and the tourists safe, for example, by enforcing the minimum required distance of 100 yards from bears and wolves, and 25 yards from the park's other animals. When talking to some of these volunteers, it becomes clear that managing the wildlife isn't the problem ... it's managing the people.

Grizzly 399, estimated to be weighing in at 350 pounds and standing 7 feet tall on her hind legs, has had one close encounter with a visitor so far. Or at least, one during which she made contact; little doubt she has had other surprise encounters with (sometimes reckless) visitors. Back in 2007, a school teacher set out on a walk near Jackson Lake Lodge in the park and inadvertently surprised 399 and her cubs while they were feeding on an elk carcass. 399 charged and bit the teacher before retreating. Luckily, 399 was spared because she acted as nature intended in defense of her cubs.


Shortly after 399 killed an elk calf in Grand Teton National Park, the elk cow returned to where she had left her calf.
The elk approached while calling out for her calf. A heartbreaking (but necessary) moment in nature.


Will She Appear with New Cubs in 2023?

If you are planning to visit Grand Teton National Park in the spring of 2023, expect a crowd.  Wildlife lovers around the world will be waiting for the news: will 27-year old 399 appear with new cubs?

After kicking out her four 2.5 year old cubs in late spring of 2022, grizzly 399 was seen on several occasions with a male grizzly boar.  The boar persistently stayed with her during mating season.  If successful, the new babies will be born sometime in January 2023, weighing one pound each!  Drinking their mother's milk, they grow rapidly and all emerge from the winter den sometime in May.

What Will the Future Bring for 399?

The future is by no means guaranteed for these extraordinary creatures. Other than the 'regular' danger of colliding with a car, there is the risk of running into trouble in human neighborhoods as happened to one of 399's four cubs in the spring of 2022: Wyoming's Game & Fish department killed the cub for reportedly seeking food in human settlements outside of National Park borders.  And, there is the ever looming threat of trophy hunters getting their way in turning these magnificent bears into a wall ornament or a living room rug. In early 2022, Wyoming's governor Mark Gordon asked the Federal Government to delist the grizzly from the Endangered Species List. If and when approved, this could see the hunting of grizzly bears, as evidenced by the recently proposed draft grizzly management plan in Montana - part of the Greater Yellowstone Ecosystem lies in Montana - that mentions a grizzly bear hunting season if Endangered Species Act protections were to be removed.  The harsh reality is that, were it not for one judge who halted the trophy hunt in 2018, 399 and other celebrity bears may well have ended up killed by now.

With the millions of dollars streaming into the coffers of the state of Wyoming thanks to Grand Teton and Yellowstone National Parks, a substantial part due to the popularity of the grizzlies, you may consider it mind boggling why the Wyoming Game & Fish Commission voted unanimously to approve the grizzly hunt.  Is the 'joy' of one trophy hunter (and the measly hunting license fee) really equal to the countless hours of joy that a bear like 399 provides to millions of park visitors annually, not to mention the economic impact those millions of visitors provide to the Greater Yellowstone ecosystem?

For now, all is well.  399 Is safely asleep in her winter den, not knowing that her plight is being followed by millions around the world.  And that her life, even after she will be long gone, will continue to play a big part in protecting grizzly bears from senseless human politics forevermore.
