Ursus arctos horribilis
Silvery-tipped hairs
The outer hairs give this bear both a "grizzled" appearance and its name.
Large hump
The large hump on the back is made of muscle and fat and is one way to distinguish it from its close cousin, the black bear.
Habitat/Range
Forests of upper North America
Wild Diet
Vegetation, Carrion (dead animals), Fish, and Small mammals
Predators
Wolves (cubs) and Humans (adults)
Reproduction
Breeding occurs in June and July, but pregnancy is "put on hold" for 3 months (delayed implantation); once it begins, fetal development takes 2 months. Cubs stay with the mother for 2-1/2 years and are fully grown at 5 years.
Conservation Status
THREATENED
Threatened in the lower 48 states. Their numbers are greater in Alaska and Canada where there are still large areas of land uninhabited by humans.
