After torpor and hibernation diverged from a common proto-hibernating ancestor of birds and mammals, the ability to hibernate or go through torpor would have been lost in most larger mammals and birds. Hibernation would be less favored in larger animals because as animals increase in size, the surface area to volume ratio decreases, and it ...
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
A hibernaculum (plural form: hibernacula) (Latin, "tent for winter quarters") is a place in which an animal seeks refuge, such as a bear using a cave to overwinter.The word can be used to describe a variety of shelters used by many kinds of animals, including insects, toads, lizards, snakes, bats, rodents, and primates of various species.
Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This is known as hibernation if it occurs during winter or aestivation if it occurs during the summer. Daily torpor, on the other hand, is not seasonally dependent and can be an important part of energy ...
The Jersey Hedgehog Preservation Group encouraged people to leave out dishes of water and bowls of dry cat food since the food would remain fresh for a few nights and benefit the teeth of the mammals.
[46] [47] To survive the winter, they are at their maximum weight shortly before entering hibernation. [48] When the groundhog enters hibernation, there is a drop in body temperature to as low as 35 degrees Fahrenheit (2 °C), heart rate falls to 4–10 beats per minute and breathing rate falls to one breath every six minutes.

Some mammals hibernate, and reptiles enter brumation. But in some cases, animals aren't as capable of surviving the harsh conditions. Here's what Texas wildlife rehabbers suggest for animals in ...
Bears use shelters, such as caves and logs, as their dens; most species occupy their dens during the winter for a long period of hibernation, up to 100 days. Bears have been hunted since prehistoric times for their meat and fur; they have also been used for bear-baiting and other forms of entertainment, such as being made to dance .
