The male grizzly bear's hibernation ends in early to mid-March, while females emerge in April or early May. [53] In preparation for winter, bears can gain approximately 180 kg (400 lb), during a period of hyperphagia, before going into hibernation. [54] The bear often waits for a substantial snowstorm before it enters its den: such behavior ...

By the time hibernation starts in October and November, males may weigh up to 1,200 pounds (540 kg). [9] These bears are known to consume as much as 120 pounds (54 kg) of salmon in a single day, sometimes catching as many as 30 fish daily. [10] Fish can help them gain up to 4 pounds a day, throughout the entirety of the season. [citation needed]
Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. [3] Hibernation may last days, weeks, or months—depending on the species, ambient temperature, time of year, and the individual's body-condition.
In addition to the fall season, bears are most likely to be observed in the spring after hibernation when they need to feed again and at the peak of breeding season, typically in July.
Overall, grizzly bear were eliminated from 98% of their original range in the contiguous United States during a 100-year period. [ 17 ] Prior to Anglo-American colonization in 1820, black bear were widely distributed throughout all major eco-regions in Texas.
