These hibernating dens are likely to be built in hollow trees, hillsides, crevices of rocks, caves, under leaves and bushes or even under the deep roots of trees. Especially bears in warmer climates like the Andian Bear, where they can find plenty of food all year round, so they have little reason to hibernate.īut the bears that do hibernate, choose to hibernate in dens.
Bats can actually fall into a deep sleep for up to six months or more, making them true long-term hibernators.Ī bat’s hibernation period usually starts in late fall and ends toward the middle part of March.Īlthough bears are famously known for hibernating, like many hibernators not all bears hibernate. However, unlike many other animals that hibernate, bats store up their food for winter and fall into a deep sleep. The heart rate drops mainly because of the dipping body temperature and immensely slow metabolism rate that bats go through when hibernating during winter. A bat’s heart rate can drop so low, that bats may not breathe for up to an hour at a time during hibernation – on and off. When hibernating a bat’s heart rate drops down from a huge 400 to 25 beats per minute.
Not all bats hibernate, some species of bats do choose to hibernate, whereas some choose to migrate to warmer places.īats that choose to remain in cold places to hibernate are most likely to hibernate in dark wall spaces or quiet and/or remote caves.īats will generally not mind sharing spaces with humans during winter, they may even hibernate near houses, or hibernate in barns, old wells, hollow trees, old and abandoned mine shafts, and even in people’s attics.
