Grizzly bear cubs nurse for up to three years, with weaning often timed by their mother's readiness to mate again. They start eating solid food early, quickly becoming less dependent on milk.
Adult grizzly bears can be surprisingly small. In places like Alberta's eastern slopes, they can weigh as little as 250 lbs in spring, smaller than local black bears!
Grizzly front claws can reach up to 4 inches in length—longer than human fingers! Avoiding these claws is highly advisable.
The hump on a grizzly bear's shoulders is a massive muscle used to power their forelimbs during daily activities. It aids in their extensive digging and den-building in steep, rocky terrain.
They are primarily found in British Columbia, western Alberta, Yukon, Northwest Territories, and Alaska, with an additional 100,000 in the former Soviet Union.
Grizzly bears can consume up to 90 lbs of food daily, equivalent to about 360 quarter-pounders from McDonald's—an astonishing feat necessitating diverse habitats free from human food sources.
Grizzly bear populations face significant threats from hunting, logging, development, and mining. Despite documented declines, legal trophy hunting continues in Canada, posing a threat to their survival.
