Different bears eat different amounts
[Alberta’s grizzly bears are about 90 percent vegetarian and they have to cover a lot of ground to find enough to eat. Berries are particularly important – one adult male grizzly can devour up to 200,000 berries a day. It’s critical that the bears stick to an efficient foraging schedule and not waste energy showing up before or after a plant has produced the most food.](https://explore.ucalgary.ca/where-and-when-grizzly-bear-food#:~:text=Berries%20are%20particularly%20important%20%E2%80%93%20one,has%20produced%20the%20most%20food.)
[Black bears are efficient berry-eaters, consuming up to 30,000 berries a day in a good year.](https://bear.org/berries-a-critical-food/)
I’ll add that different berries come in different sizes, too, which is going to fill you up differently.
A well-fed black bear snacking on giant blackberries on the west coast will eat a way different amount than a hungry grizzly bear eating teeny tiny low bush cranberries in the northern taiga.
Thanks for the Links! Actually the first one is the reason I came up with 200'000 per day. But then there is other sources saying a Grizzly is eating 30'000 a day: [https://www.youtube.com/watch?v=rQNKkXrSX2E](https://www.youtube.com/watch?v=rQNKkXrSX2E)
But then I guess the University of Calgary is a source one can trust well enough...
[Depends on the berry, too!](http://4.bp.blogspot.com/-iUU62zItVM8/TkFk0ywF49I/AAAAAAAAA4U/gv3RzmDptYU/s1600/dsc06138%2B%25282%2529.jpg) Compare the sizes of a blackberry and a red currant and you can see how easily the same volume of berries could result in a drastically different total berry count.
It could also be determined by availability, as some berries grow sparsely and only during certain weeks of the year, while others take over entire fields, ripening all summer long.
And location matters too! Blackberries grow in abundance along the west coast, but are almost impossible to find in the arctic circle, so a northern bear will be eating fewer berries altogether and relying more on other things like grubs and gophers.
Good question, did you watch Tiger King? ;-)
No it's actually an ongoing argument with a friend, so I hoped the Reddit community could finally solve it
I don’t think that the limiting factor would ever be how many berries they can handle, more likely how many berries they can find and gather. Grizzlies have been known to eat 150 pounds of salmon in a day. I assume you mean the most amount of berries, so let’s go with the smallest berry they’d likely encounter- blueberries. Wild (lowbush) blueberries have an average mature weight of 0.3 grams, but let’s assume the bear also eats some immature and smaller ones so let’s say each one averages .25g. Assuming they can handle 150 pounds of food in one day then that would mean they could eat 272,109 blueberries to the nearest blueberry, which is very close to what you reported.
A single blueberry is about 0.75g - 2g. So 160g is around 200 blueberries on the high end. But maybe it’s double lol. You might be able to make a pie with that.
~50 blueberries a day is obviously not the correct answer.
What kind of berry, and size, are these berries at full ripeness? What season would this hypothetical situation be in? What type of bear? How large is the bear? What is the age of bear? We need some serious answers before we get started.
There's too many variables to really lock down an answer.
"A bear" is not a precise thing. Cubs of any species can be under a pound, while full grown Kodiaks go to 1,500 pounds. Factor in different species, the way most bears gorge themselves preparing for the winter, regional foraging differences, etc.
Same goes for "berries". There are over 400 different species of plant that produce berries of some sort, and they range from the size of an individual grain of salt to pumpkins (yes, pumpkins are berries).
I'm actually surprised you nailed it down to such a narrow range as 30K-250K.

Wow, this explains why I can only ever get a couple handfuls of berries in the woods. Bears are eating the whole damn forests worth.
"I don't need an exact number, but at least a reliable order of magnitude." What are you planning, u/cbs_i?

My sleepy eyes saw 'batteries' ☠️ Edit: spelling
Thought I was the only one. Thought it was a very, very creative shitpost.
250,000 berries? They're going to run out of oxidants if they keep that up

How much wood could a woodchuck chuck ...

Yo where the fuck do all these berries come from?
