Like many senior citizens, she is having trouble seeing and hearing, so the DNR is urging hunters who encounter her to show respect.
The world’s oldest known wild bear — a 39½-year-old black bear that has roamed the woods near the Bigfork-Marcell area of northern Minnesota — might be running out of time and luck.
The elderly female bruin, simply called No. 56 because of the numbered tag she was given when radio-collared by researchers in 1981 at age 7, has trouble hearing and seeing and navigating the thick woods. So the bear is using roads and trails, and is more frequently encountering area residents.
Because of those factors, researchers say she is now more vulnerable to being hit by a car or shot as a nuisance bear or by hunters — and they are asking residents for patience.
They would like No. 56 to die of natural causes.
“We’ve never seen a wild bear die of old age,’’ said Karen Noyce, Department of Natural Resources research biologist in Grand Rapids who has been monitoring No. 56 since she first tranquilized and attached a radio collar to the bear 32 years ago. “It’s just extremely rare. We’re not going to crack any secrets, but it’s so rare to get an opportunity to watch a wild animal age normally.
“We’re trying to get the word out to everyone in that area. A lot of people already know about her.’’
Jayson Hansen, DNR conservation officer in Bigfork, said people are seeing the bear on roads and sometimes near their homes. “She’s been sighted numerous times this spring,’’ he said. He asked residents to treat the bear with respect, and said it likely will run off once it senses a human.
How rare is a 39-year-old black bear?
• The average age of a bear killed by a Minnesota hunter is less than 4 years old.
• About 80 percent of No. 56’s estimated 26 cubs died by age 6. (She last gave birth at age 26.)
• Of the hundreds of bears that have been radio-collared and studied by the DNR over the past 32 years, the longest any survived was 23 years.
“Some bears in zoos have made it into their 40s,’’ Noyce said. “But in terms of a wild bear, one whose age has been documented and studied, no one has had a study bear over age 35.’’
Bear isn’t drunk
Noyce and other researchers have located No. 56 every three years to tranquilize her and attach a new radio-collar. They last did that in 2010, but Noyce recently used the radio-tracking device to find the bear to see how she was doing.
“She doesn’t hear much, and can’t see much,’’ Noyce said. “I got to within about 10 feet from her, downwind, and she was sound asleep. I moved upwind of her, about 20 feet away, and she immediately got up and made a beeline away from me. She was definitely aware of me.’’
Added Noyce: “Her gait is a little unsteady. When people see her they think she looks drunk. That’s because no one ever sees an old, old, old bear like that. But she doesn’t seem to be in any pain.
“Her teeth have been terrible for six years, but she still has teeth,’’ Noyce said. The bear was nearly 200 pounds when last weighed three years ago. “She’s thin now,’’ Noyce said.
Though the bear’s days are numbered, Noyce said she has no idea how long the old gal might live, adding: “I can’t predict. She could lie down and die tomorrow, or keep going.’’
But residents shouldn’t assume the old bear is safe to approach just because it doesn’t run off as younger bears usually do.
