Grizzly bear mom's have to be alert if they have cubs with them. Big males would take advantages and possibly even eats her babies. This is one of the reasons why we see mom's standing up once a while, especially when they can smell something they don't like.
I photographed this photo on one of my Wildlife & Scenery Photo Tour in the Great Bear Rainforest along the beautiful British Columbia coast. I ran my photo tours from my B&B "The Artists Point" which is located on Northern Vancouver Island close to Port McNeill.
