Watchful by Cheryl Strahl Via Flickr: A sow with her cub will sometimes look like she is smacking her lips when she senses another bear approaching them. Her body language basically conveys her expressions of fear, nervousness and apprehension. She will usually retreat after she demonstrates this behaviour. We witnessed this several times as the bears came and went from the bend in the creek. Funnel Creek, Katmai National Park and Preserve, AK. Seen during the Sockeye Salmon run this past summer.
Watchful Mother Bear by David & Shiela Glatz Via Flickr: First time we've seen this mother bear at Silver Salmon Creek. She had her first litter of cubs this January or February. Here she's being a dutiful and watchful mom, keeping her eyes on the strange group of humans while her two cubs feed on grass. Haven't seen Brown Bears feeding on the grass during salmon run - this little family did it quite often. Mom was an excellent fisher, though, so she and the cubs won't be relying solely on grass to get them through the winter. Don't think that would work out so well. Lake Clark National Park, Alaska.
