The snow melts and bears leave their dens. Adult males leave their dens first while mothers with cubs are the last to leave their dens. Food is very scarce. Adult males begin to roam. All bears lose weight at this time of year.
Green plants begin to grow and trees begin to sprout leaves.
They begin to eat sprouting grass, emerging herbs and young aspen leaves. Cubs taste what their mother eats, but swallow very little or it. They still rely on their mother s milk. Mother bears that are nursing young cubs continue to lose weight. Other bears slowly begin to gain weight.
