State wildlife officials estimate the state's black bear population has remained stable for the past 10 years at 50,000 to 81,000 to animals. Bears can hibernate under decks, in crawl spaces
As bears wake from their extended slumber, they’re following their hunger. Hungry bears are coming out of hibernation, Yellowstone rangers say. How to stay safe
They go into hibernation when the temperatures start to drop or when food is hard to come by. Like bears do, they "bulk up" for their hibernation before they choose to do it. Their heart rates ...
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.
Many of the physiological changes an American black bear exhibits during hibernation are retained slightly post-hibernation. Upon exiting hibernation, bears retain a reduced heart rate and basal metabolic rate. The metabolic rate of a hibernating bear will remain at a reduced level for up to 21 days after hibernation. [92]
In particular, adult male bears can gain up to 500 pounds (230 kg) or more. [9] 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]
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.
[110] [111] During hibernation, the bear's metabolism slows down, its body temperature decreases slightly, and its heart rate slows from a normal value of 55 to just 9 beats per minute. [112] Bears normally do not wake during their hibernation, and can go the entire period without eating, drinking, urinating, or defecating. [47]
