Bears normally stock up on food then hibernate in their dens during the coldest winter months. Bear hibernation is “strongly tied” to weather patterns and food availability, according to a ...
In the state's history there is only one documented fatality from a bear attack when a 22-year-old Rutgers University student was killed by a bear in West Milford in 2014.
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 ...
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.

Today, it is more common for hunters to use dogs to track a bear. Often riding in the back of a truck to catch a scent, the dog will start to bark when there is a track. Dogs will then follow the track showing the way for the hunters. [23] Modern bear hunters use hounds of mixed breeding to tree bear. [24]
A grizzly bear at Maryland Zoo was captured on CCTV struggling to stay awake as hibernation season approaches. During their long winter sleep, the body temperature of a bear dips to about 30-35C ...
Although naturally-made dens are occasionally used, most dens are dug out by the bear. [68] During their time in hibernation, an American black bear's heart rate drops from 40 to 50 beats per minute to 8 beats per minute, and the metabolic rate can drop to a quarter of the bear's (nonhibernating) basal metabolic rate. These reductions in ...
