![]() Short states of torpor are an energy-saving survival strategy just like hibernation. The best way for bats to save energy is not to use up what they already have available to them. The lack of a food source means less energy. That’s because there is less insect activity during poor weather conditions. If the temperature drop below 50☏ (10☌) for a few days then a bat will go into a state of torpor. ![]() Reduce their heart rate to 4-80 beats per minuteĭuring Torpor a bat won’t drop their temperature as they do when in hibernation mode.Ī bat will normally use periods of torpor at any time of the year when weather conditions are poor.Going into torpor means bats can reduce the energy consumption from body functions, but not as severely as with hibernation. Think of torpor as a less extreme version of hibernation. This may lengthen or shorten depending on when the daily temperatures rise above 50☏ (10☌). Bats will usually go into hibernation mode from November through to March. The change in temperatures and lack of insects will trigger a bat’s hibernation behaviors. Bat hibernation will last for around 6 months of the year. Going into a state of hibernation helps bats to survive over the winter months. They know that food supplies during the winter are scarce. Lower their respiratory rate to 5 breaths per minuteĪ bat’s ability to slow all these essential body functions helps them to save as much energy as possible.Lower their body temperature to around 35.6☏ (2☌).Drop their heart rate to as low as 4 beats per minute.Hibernation is an extreme state of dormancy that bats use during the winter months.īy going into a state of hibernation bats will: Let’s take a look at what each dormant state is and when bats use it. Bats can do both depending on their environment. Hibernation and torpor are both states of dormancy and can be used interchangeably. This guide will take you through everything you need to know about what bats do during the winter. Bat hibernation lasts for 6 months (183days) to allow them to survive harsh winter conditions. This type of hibernation allows bats to lower their heart rate, metabolism, and body temperature. They will go into a dormant state known as extended torpor. Some bat species do hibernate in the winter months. Do bats hibernate? You may be asking yourself this is you haven’t seen any bats during the autumn or winter nights.
