pretty much everyone that see's a bear says THAT"S A BIG ONE LOL
as most folks see them very seldom and to be honest bears ARE the hardest animal to judge, as every different angle you view than at can make them look larger or smaller than they really are
I am exposed to bears very very often, almost daily 6 months out of the yr!

IMO
and its just THIS< as I find it very hard to give weights on bears from pictures, doe to again, things that you can use to judge are unknown

BUT, IMO< that is a male, in the 350-400 lb range, nothing HUGE, by black bear standards of what BIG one's can weight(some are near 900's in the record books)
and I would not say he is that old of a male either , maybe 5-6 yrs old or so IMO

be a very nice bear for anyone hunting them to get for sure,
but its no monster black bear!
