Bats
When it gets too cold or there isn’t enough food, bats enter a decreased hibernation condition called torpor, which lasts all night. Some species go one step further and hibernate through the winter. Typically, those residing in regions with fewer insects are found there. Bats cluster together from cave ceilings or walls and can slow their pulse rates to 10 beats per minute while they are in torpor or hibernating. Bats normally start hibernating in October or November when the cold weather drives the insects away and comes out of hibernation in March. Based on regional variances in seasonal temperature, bat hibernation habits can differ.
Common Poorwill
A nocturnal member of the nightjar family Caprimulgidae is the common poorwill. The majority of birds do not hibernate, which is why you don’t hear much about it. The only one does so because wintertime insect food is scarce, and that is the common poorwill. The birds wait out the winter by slowing their metabolic rate and hibernating in a hollow log rather than migrating. As the first bird species known to hibernate for weeks or even months in the wild, the Common Poorwill has garnered notoriety. During the 1947–1948 season, one was known to hibernate for at least 85 days.
Wood Frogs
When it comes to hibernation, wood frogs go one step farther than the majority of animals by fully ceasing to breathe and having a beating heart. They actually become so cold that ice crystals start to develop in their blood. For the winter, they hibernate in logs, burrows, or heaps of leaves, where they stay until the summer when they warm up and reactivate their breathing. The approach taken by wood frogs is different. They burrow beneath the lush undergrowth on the forest floor to hibernate. Shielding the frogs from extreme cold are the leaves, litter, and overlaying snow.
Hedgehogs
Depending on how cold the winter is, hedgehogs can hibernate for a few weeks or several months. Hedgehogs’ heart rates can fall by up to 90% while they are hibernating, yet if it becomes too cold, they may briefly awaken. When they awaken, their hearts beat faster, warming them up a little before they fall back asleep. Typically, hedgehogs hibernate from October/November until March/April. Each individual is switches nesting locations at least once throughout this time. According to research, this means you will see them occasionally out and about.
Box Turtles
The number of turtles that hibernate varies by species and geographic area. Box turtles hibernate three to five months each year. They create an underground burrow for themselves, slow their heart rate to 5 to 10 beats per minute, and cease breathing entirely. They do not, however, lack oxygen because they absorb it via their skin. Three-toed box turtles can hibernate for up to five months out of the year due to a lack of food, the cold, and dry circumstances.
Garter Snakes
In contrast to the solitary hibernation of many other species, garter snakes prefer to spend the winter with their own kind. Snakes can number in the hundreds or even thousands, and their den is where they all spend the winter together. For cold-blooded animals, closeness is a boon because heat retention is so important. Hibernation is necessary for the red-sided garter snake to survive Manitoba, Canada’s -40 degree C winters.
Bears
Bears are perhaps the first animal that comes to mind when you think about hibernation, but they don’t truly do it, at least not in the genuine sense. Torpor, however comparable to hibernating in bears, is a distinct state. Bears’ breathing and heart rates slow down while they are in torpor, and their body temperatures drop, though not as much as those of species that hibernate.
Marmots
There are 15 species of giant ground squirrels known as marmots, which are found in Asia, Europe, and North America. These herbivores can frequently be spotted in groups throughout the summer when they are active, but they are not visible in the winter when they are hibernating underground.
Bumblebees
Although not all bees hibernate, for the bumblebee, at least for the queen, it is an essential aspect of existence. When the temperature drops, every male and worker bee perishes, leaving the queen to locate a suitable location to spend the winter.
Snails
Although you might not think of snails as the first animal to hibernate, some do. Snails hibernate inside their shells, sealing the opening with mucus to retain moisture inside and prevent drying out. They also defend themselves from hot weather, albeit this is known as aestivation, not simply in cold weather.
