Mummy bear and her cubs

My father recently went to the piece of forest land owned by his brothers. He discovered from the surveillance cameras that a few minutes before he went there, they've had visitors: this black she bear and her two cubs. I must say that I was a bit scared when I found out: female bears can be very aggressive when they fear for their youngs. I asked my dad to be careful. That being said, I love black bears and I can't help but find the pics of this family very cute.
