Bears are not known as being the most active creatures in zoo environments. They may wander around sniffing for food or take a dip but they are just as likely to be sleeping as anything. Getting some more activity is, therefore, a reason for some celebration. The reason was that the enclosure had two Grizzlies that are brothers. Put two tough brothers together and guess what happens. They start fighting.
Nothing dramatic. None of this was serious. Just the sort of sparring that boys will do if no one stops them. Of course, they do fight behind some branches so you don’t have quite as clear a view as would be ideal. Even so, watching them wrestle and bare their teeth at each other was a lot of fun.
