Green Forest

Alberta, Canada

I was watching a mother black bear ( Ursus americanus ) play fighting with her cub. A second cub jumped up on a log to get a better look for a few seconds. These bears have quite the vocabulary, and use a variety of grunts, hums and vocalizations to communicate with each other. Some researchers, having overheard these conversations, say they can be surprisingly 'human-like'.
