17 The Bat Facts: Unveiling the Mysteries of These Flying Mammals

Bats, in several instances, have a bad reputation and are seen as scary, blood-sucking creatures that carry rabies and live in caves only celebrated during Halloween. However, these flying mammals are essential to the ecosystems in which they live.

With over 1,400 species of bats, they make up a significant portion of all mammals and are the only mammals capable of flight. Discover the secrets behind their pointy ears and veiny wings, making them one of Earth’s most crucial animals.

Facts About The Bats:

Bats: A Diverse And Widespread Species Across The Globe:

There exist more than 1,400 bat species across the globe, except in extreme deserts and Polar Regions. Bats come in various sizes and shapes, ranging from Kitti’s hog-nosed bat, which weighs less than a penny and holds the record for the world’s smallest mammal, to the flying foxes that boast wingspans of up to 6 feet.

The United States and Canada host around 45 bat species, while other species are present in American territories in the Pacific and Caribbean regions.

Size Matters: Adaptations and Prey Selection in Bats:

Kitti’s hog-nosed bat, or the bumblebee bat, holds the title for the smallest bat species measuring only 29-34 mm long with a wingspan of 150 mm and weighing 2-2.6 g. In contrast, the giant golden-crowned flying fox can weigh up to 1.6 kg and have a wingspan of 1.7 m.

The size of a bat can affect its echolocation abilities and prey selection, with larger bats using lower frequencies and smaller bats relying on higher frequencies to detect prey.

Bats Conserve Energy to Survive:

During hibernation, bats experience a significant decrease in metabolic, heart, and respiratory rates, enabling them to survive extended periods without sustenance. Typically, a bat’s heart rate decreases from 200-300 beats per minute to merely ten beats per minute, and it may even pause breathing for several minutes.

Depending on the bat’s surroundings, its body temperature can drop to near freezing. Additionally, other bodily functions slow down, reducing energy costs by about 98%. Thus, bats are experts in high energy efficiency during this state of “torpor.”

Bats Survive the Cold Months:

Bats can enter torpor to conserve energy for a few hours on a cold day, or they may remain in torpor for an extended period, up to a month, during hibernation over winter. During hibernation, bats go through cycles of torpor, with brief periods of arousal when their body temperature returns to normal for several hours.

Some species, like the little brown bat, hibernate for more than six months, awaiting the return of insects in the spring. Bats prefer locations such as caves, mines, rock crevices, and structures with ideal temperature and humidity for hibernation, which are known as hibernacula.

White-Nose Syndrome: The Deadly Disease Decimating Bat Populations:

Bats are not preyed upon by many natural predators, but diseases like the white-nose syndrome have emerged as significant threats, causing millions of bat deaths. This disease affects hibernating bats and has been found in several US states and Canadian provinces.

It decimates the populations of certain species, like the northern long-eared, little brown, and tri-colored bats, which have seen over 90% of their population wiped out in under a decade. Researchers are trying to understand the disease, and one can help by avoiding hibernation sites and disinfecting gear when visiting underground areas.

Surprising Facts About Their Longevity and Speed:

With a lifespan of over 30 years, bats can achieve incredible speeds while flying, reaching up to 60 miles per hour or more.

A study conducted by the University of Tennessee revealed that the Mexican free-tailed bat could soar at speeds up to 100 mph, making it the fastest mammal on Earth.

Bats: Master Hunters of the Night:

Bats have the capability to locate their food in complete darkness. While not all bats are nocturnal, those that rely on a process known as echolocation to locate their prey. They emit high-pitched sounds, usually between 10-20 beeps per second, which are inaudible to human ears, and then listen for the echoes that bounce back from objects in their surroundings.

This process helps them determine their prey’s location, size, and speed, even in complete darkness. With the ability to navigate in the dark, bats are expert hunters and play a vital role in maintaining a balanced ecosystem.

Breaking the Rule of Longevity: Bats Can Live for Over 40 Years:

Bats are often considered to have a shorter lifespan due to their small size. However, they have proven to break the rule of longevity, as the longest-living bat on record is 41 years old.

Even though most bats in the wild live for less than 20 years, six species have been documented to live for over 30 years. In 2006, a Siberian bat set a new world record for the longest-living bat at 41 years, proving that these fascinating creatures can live longer than we initially thought.

Baby Bats and Their Nursing Mothers:

Did you know that baby bats are also called pups and that, like other mammals, they are nourished with breast milk?  While dogs aren’t the only ones with pups, most bats give birth to just one pup, though there is one species, the eastern red bat, that commonly has twins.

Mother bats form nursery colonies in caves, dead trees, and rock crevices to care for their pups in the spring. These colonies are essential for the survival of the young bats, as they provide warmth, protection, and a sense of community.

The Nature Conservancy’s Mission to Protect the World’s Largest Bat Colony in Texas:

The Bracken Bat Cave in Texas is a vital habitat for the world’s largest bat colony. Every year between March and October, millions of Mexican free-tailed bats roost in the cave.

Unfortunately, their home is under threat due to the expansion of nearby cities and development. The Nature Conservancy is working hard to protect this species by securing 1,521 acres of land around the Bracken Cave.

The Valuable Resource of Bat Guano: A Rich Fertilizer:

Bat droppings, or guano, are among the most nutrient-rich fertilizers available. Earlier, the guano trade was a significant industry, with Texas exporting large volumes of the same. Today, Austin is home to one of North America’s largest urban populations of Mexican free-tailed bats, with about 1.5 million residing beneath the Congress Avenue Bridge.

The accumulation of bat guano in this area has created a valuable resource to nourish crops and improve soil quality. The trade may no longer be as lucrative as it was, yet bat droppings remain a vital resource for farmers.

Unexpected Discoveries: Rhodococcus Rhodochrous and the Preservation of Fruit:

The researchers at Georgia State University initially focused their research on Rhodococcus rhodochrous, a common bacterium, to investigate the efficacy of VOCs in delaying fruit ripening. Little did they know that their study would eventually uncover the unexpected role of this bacterium in preserving fruit and potentially benefitting the food industry.

The study focused not on bats or fungi but on the chemical signals fruit emits during ripening, which can lead to spoilage during long-distance transportation.

Magnetoreception in Microbats: Understanding their Sensitivity to Earth’s Magnetic Field:

Microbats, similar to birds, possess a heightened sensitivity to the Earth’s magnetic field, utilizing magnetoreception.

Unlike birds, microbats rely on a polarity-based compass to differentiate between north and south rather than the strength of the magnetic field, which is beneficial for short-distance navigation. Although the mechanism for this sensitivity is not yet understood, it is believed that magnetite particles may play a role.

Thermal Strategies of Bats: Balancing Heat Loss and Energy Conservation:

Bats employ several thermal strategies to maintain a stable body temperature. Although most species are homeothermic, including vesper bats, horseshoe bats, free-tailed bats, and bent-winged bats, they rely on heterothermy to regulate their body temperature.

 Bats have a high thermal conductivity compared to other mammals due to the blood vessels in their wings. However, at rest, they can wrap their wings, covering themselves to trap a layer of warm air. Smaller bats have a higher metabolic rate than larger bats and require more food to maintain their body temperature.

The Comfortable Life of Upside-down Bats:

Bats have a natural aptitude for hanging upside down. Unlike us, their bodies find this position comfortable. Their tiny feet can lock into place, preventing them from falling tired.

In contrast to humans, the blood flow in their bodies does not rush to their heads when they hang upside down, as it would if we were to hang from monkey bars in a playground. This ability to hang upside down is advantageous for bats, as they can rest, sleep, and mate while protected from predators.

The Vital Role of Irish Bats in Controlling Insect Populations:

Bats have adapted very well to life in Ireland. They remain active during the warm months when insects are abundant but hibernate during the winter when food is scarce. One of the key benefits of having bats around is that they are excellent at consuming insects that humans find bothersome, such as biting midges and mosquitoes.

In fact, a single pipistrelle bat can consume up to 3000 of these insects in one night, so the more bats that exist, the more they can help us control insect populations.
