Originally posted by JimB: I'm a taxidermist that does a lot of blacks,grizzlies and brown bears.Regardless of what you read,all bears have rounded ears.You can take the cartilage out of a black bear ear and lay it beside that of a grizzly and you can't tell one from the other.What is different,is that the grizzlies and browns have much longer hair on their ears which often makes the ears look much more like a puffball than black bear ears.This is why black bear ears may look less round to some.Grizzlies also never have a distinctly lighter muzzle like many black bears do-but not all.I think your bear has a lighter tan muzzle which would be a contrast to his otherwise brown/black color.This is why I say it is a black bear.It has enough crease in his head that I believe it is older than 4 1/2 but hard to pin down and impossible to tell gender.You may get more pictures of it.Places like water troughs where bears can dunk themselves are very important in hot weather.Find a place like that and you should get multiple bear pictures.Go back and look at your grizzly and black bear pictures again and look at those features.Hopefully you can see what I mean.If you do a search for MT FWP (our game department)they have a grizzly test for hunters.It is interesting to take and it helps you understand that when dealing with color phase black bears,you sometimes have to look close to tell them from grizzlies.
