Cubs, usually two, are born in late January. They weigh 8 ounces when born. Cubs remain with their mothers for about 18 months. Mothers with cubs will remain in their dens until early May. July starts the mating season. Young males often travel more than a 100 miles to find a mate.
Fertilized eggs lie dormant until denning.
Once awake the search for food begins. Spring foods are scarce, so bears conserve their energy. Berries ripen in July and cherries in August. If the crop is good, these fruits provide ample food. Acorns provide a source of winter fat.
