What Is the Age of the Oldest Brown Bear in Yellowstone That Has Ever Been Documented?

Scientists discovered one of the world's oldest grizzly bears — a 34-year-old specimen in the southwest corner of Wyoming. They were able to identify him quickly because of a characteristic mark on the lip that had been developed by scientists in 1989. The fact that scientists have not been able to tag or identify the majority of the animals inside the Yellowstone region means that there is no indication that there are any other elder grizzly bears in the area other than this one. In this article, we'll discover more about the grizzly bear that has lived in Yellowstone Bear World for the longest time.

  • The Bear's Historical Background

Researchers have established that Grizzly 168 was taken for the first time when he was roughly three years old, based on previous documents collected. This was also the year that biologists gave him his unique tattoo, and it was also the year when scientists seized him for the second time, this time in Fremont County, Wyoming, in 1996.

The loss of his radio collar over the next year prevented scientists from conclusively determining exactly what was going on with Grizzly 168. However, some DNA testing have shown that he may have fathered three children later in his life, during the mid-2000s. The tests also revealed that he had more children when he was 23 years old, and that the number of children grew when he was 31 years old.

One of the most well-known brown bears in the Yellowstone area is bear 399, a 24-year-old grizzly female who subsequently became the world's oldest grizzly bear mom at the age of 27. Bear 399 is one of the most well-known brown bears in the Yellowstone region. Grizzly 168, on the other hand, had only three teeth remaining when he was originally captured, which was an indication of his advanced age.

His teeth were badly grounded, which is a clear indication of why he preferred to hunt for easier food such as calves. Aside from being underweight, the grizzly weighed just 77 kilos (170 pounds), which is much less than the average weight of a grizzly bear.

  • The Bear's Physical Condition

Yellowstone scientists often rate a bear's physical health on a scale of 1 to 5, with 1 representing the bear in the poorest condition and 5 representing the bear in the best condition. Whenever the Grizzly 168 was initially seized, he was given a zero rating, mostly because of his malnourished state of health. This ultimately compelled scientists from the Fish and Game Service to make the decision to put him out of his agony rather than relocating him to an isolated region of Yellowstone National Park.

"It was terrible that we'd have to euthanize him," Dan Thompson, a scientist with Wyoming Fish and Game, told the Grand Hole News and Guide. "But there was nothing more we could have done ethically."

  • The Amazing Story of Grizzly 168'S Longevity

The Greater Wyoming Ecosystem still faces dangers, including hunting and habitat degradation, despite the fact that there are only 700 grizzlies living in the area. Climate change has also had a significant impact on bear diet and winter hibernating, which makes Grizzly's 168-year life span a near miracle in comparison to other bears.

  • Grizzlies at Yellowstone National Park Have Reason to Be Hopeful

Grizzly bear populations have steadily expanded since federal protection was granted to them in the 1970s, despite the fact that they pose a significant threat to human health. Grizzly bear populations, for example, grew by 100 percent in the Yellowstone area between 1970 and 1980, according to the National Park Service. Grizzly 168's children, hopefully, have a wonderful future ahead of them.
