When temperatures warm up and food is available, brown bears slowly begin to leave their dens. After 4-5 months of sleep and limited activity, male bears emerge first, usually from early to mid-March, followed by solitary females and females with yearlings or two year olds. The last to leave their dens are females with newborn cubs. Spring greens and winter carrion are first on the menu for these hungry bears.
