Well, the simple answer would be in the woods.
The FBI didn't report the most crime-ridden cities.
They didn't do it.
They eat a lot of berries, yeah, depending on what area of their range we're talking about.
But in some areas, their diet is really dominated in the fall, especially by berries.
That's correct.
Yeah.
I mean, their whole life history in a way is driven by the fact that they spend five, six, sometimes seven months, depending on what area we're talking about, in hibernation.
So their whole strategy throughout the active season is to accumulate fat to prepare for hibernation.
And so the fall period is what we refer to as the hyperphagia period.
That is the
period of hyper consumption of foods and just getting the calories.
That means that some bears will spend upwards of 20 plus hours a day looking for food.
You see that number, or there's also numbers of over 200,000, so somewhere in the range of 200,000 to 250,000.
You see that number quoted quite often.
There is this report from a Canadian wildlife biologist by the name of Arthur Pearson.
And it's a report on what I consider kind of a classic bear study, in this case on grizzly bears in the Yukon territory.
It's a classic study because it's really one of these naturalist studies where people spend a lot of time in the field studying bears, observing bears, radiocoloring them, capturing and radiocoloring them.
What they did, they counted the number of berries in bear scat.
And you can imagine that's quite an endeavor.
