We love this photo of a mother (sow) grizzly watching over her cub of the year (CoY). On average, grizzly bear cubs stay with their mothers for two years before being chased off to survive on their own, with females usually carving out their territory near where they were raised.
Though not common, it’s also not rare for a grizzly sow to keep their young for three years, including a bear family we’re documenting in BC for Nature Labs. Of course, Yellowstone’s ‘Raspberry’ raised her 2015-born cub, ‘Snow’ (so nicknamed by Jill due to the cub’s light colouration and the name stuck…much to Simon’s chagrin who has never named a bear!), until late this spring and we are aware of at least one grizzly that kept two cubs until age four.
