Glacier Bay National Park is home to brown/grizzly bears (Ursus arctos) and black bears (Ursus americanus). Black bears are found primarily in the forested regions of the lower bay, including Bartlett Cove, while brown bears live mainly in the open, recently deglaciated regions of the upper bay.

Brown bear is another name for grizzly bear and is used to differentiate the coastal residents from the interior-dwelling grizzly. Brown bears can be any shade from honey blonde to black.
