Bats face significant challenges during the cold season, primarily because their food sources become scarce. Insects, which make up the majority of a bat’s diet, are not readily available during this time. So, how do bats survive the winter? The answer lies in their remarkable ability to adapt through two main strategies: hibernation and migration.

Hibernation is the most common survival method for bats in colder climates. During hibernation, bats undergo dramatic physiological changes. They significantly reduce their metabolic rate, lower their body temperature, and slow their heart rate from about 300-400 beats per minute to just 10 beats per minute. This allows them to conserve energy and live off the fat reserves they’ve accumulated during the warmer months. Hibernation is crucial for their survival, enabling them to endure long periods without food.

How Do Bats Survive the Winter

Interestingly, not all bats hibernate. Some species migrate to warmer areas where food remains abundant. These migratory bats can travel substantial distances to find suitable climates and food supplies. Even more fascinating, some bat species employ a combination of both strategies – migrating to locations where they can safely hibernate.

It’s worth noting that in some warmer climates, bats may neither hibernate nor migrate, remaining active year-round if food sources are available.

The choice between hibernation, migration, or staying active often depends on the species and geographic location. For instance, in our work at Skedaddle in Victoria, we encounter hibernating bats, as many local species prefer to stay closer to their normal habitats rather than undertake long migrations. However, this can vary depending on the specific region and the bat species present.

Understanding these survival strategies is crucial for wildlife control professionals and homeowners alike. It helps us anticipate bat behaviour and implement appropriate, humane measures to manage bat populations in urban areas while respecting their important role in our ecosystems.

Dietary Needs During Hibernation

During the winter, the question on many people’s minds is, what do bats eat when there are no insects around? The simple answer is, they don’t eat much at all. Before winter arrives, they consume large quantities of insects to build up a reserve of body fat. This fat is what sustains them throughout their hibernation period. Unlike other animals that may forage occasionally during hibernation, bats rely entirely on these fat reserves. 

In regions where the climate remains relatively mild throughout the winter, some bats may occasionally emerge from hibernation if temperatures rise unexpectedly. During these brief periods of activity, bats might search for any available food sources. However, such occurrences are rare and not typical behaviour for hibernating bats. 

At Skedaddle, we understand that bats are part of a unique ecosystem and play a vital role in controlling insect populations. Their feeding habits during the active months help keep mosquitoes and other insects in check. This natural pest control is one reason why it’s important to appreciate and protect bat populations, even as we work to ensure they don’t make homes inside human structures during the colder months.

The Role of Fat Reserves

The amount of fat a bat accumulates before winter is directly related to its survival chances. Bats need to eat a considerable amount of insects to build up these reserves. In fact, during peak feeding times in the late summer and early autumn, bats can consume up to their body weight in insects each night. This intense feeding period is essential for their winter survival strategy. 

Without adequate fat reserves, bats may not survive the winter. This reliance on fat storage also makes bats extremely vulnerable to any disruptions during hibernation. If disturbed, a bat can quickly burn through its fat reserves as it attempts to wake and escape. This is why it’s crucial for bats to find safe, undisturbed places to hibernate, such as caves or unused attics.

In my work with Skedaddle, I often emphasize the importance of ensuring that bats have access to natural habitats. When bats enter human structures, it can lead to conflicts, especially if they are disturbed during their hibernation period. Our role at Skedaddle is to humanely handle these situations, ensuring that bats are relocated safely and that their entry points are sealed to prevent future incursions.

Migration as an Alternative

While many bats hibernate during winter, some species opt for migration as their survival strategy. These migratory bats head to warmer areas where insects are still plentiful. This journey is no small feat and requires careful preparation.

Unlike birds, bats don’t bulk up significantly before their trip. Research shows that bats only increase their body mass by 12% to 26% through fat storage. In contrast, birds can pack on up to 50% more weight before migration. To make up for this, bats use a clever approach to fuel their journey. They burn both their stored fat and catch insects along the way, allowing them to save energy for both the migration and the hibernation that follows.

The distances these bats cover can be impressive. Take the Nathusius’ bat, for example. These tiny creatures have been known to travel up to 2000 km between their summer homes and winter hideouts. That’s like flying from Toronto to Florida!

At Skedaddle, we’re fascinated by these migratory patterns and behaviours. Understanding them helps us in our mission to protect both the bats and property owners. We always aim to find solutions that keep everyone safe and comfortable, whether dealing with local bats or those just passing through on their long journey.
