The hoary wattled bat (Chalinolobus nigrogriseus) is a fascinating small bat. It belongs to a group called vesper bats. You can find these bats living in the northern parts of Australia and in Papua New Guinea.
Scientists recognize two slightly different types, or subspecies, of the hoary wattled bat:
- C. n. nigrogriseus, first described by John Gould in 1852.
- C. n. rogersi, identified by Oldfield Thomas in 1909.

Discovering the Hoary Wattled Bat
Have you ever wondered who names animals? The hoary wattled bat was first officially described by a famous English ornithologist, or bird expert, named John Gould. He documented this species in 1852. Later, in 1909, another scientist, Oldfield Thomas, identified a second subspecies. These scientists help us understand the amazing diversity of life on Earth.
What Makes a Vesper Bat Special?
The hoary wattled bat is part of the Vespertilionidae family, commonly known as vesper bats. This is one of the largest bat families in the world! Vesper bats are known for their small to medium size. They also have simple faces without leaf-like nose structures. Most vesper bats use echolocation to find their way and hunt.
What Does the Hoary Wattled Bat Look Like?
This bat gets its name "hoary" from its fur. "Hoary" means grayish or frosted, like old hair. The hoary wattled bat has dark fur, often with lighter, frosted tips. This gives it a grizzled or "hoary" appearance. It is a relatively small bat, perfect for zipping through the night sky.
Understanding Its Unique Features
The scientific name, Chalinolobus nigrogriseus, tells us more. Chalinolobus refers to the "wattles" or fleshy lumps found on its face. These are usually near the corners of its mouth. Nigrogriseus means "blackish-gray," describing its fur color. These wattles might help the bat sense its surroundings or even communicate.
Where Do Hoary Wattled Bats Live?
These bats call the tropical and subtropical regions of northern Australia and Papua New Guinea home. They prefer warm climates with plenty of trees. Their habitat stretches across various states in Australia, including Queensland, the Northern Territory, and parts of Western Australia and New South Wales.
Preferred Habitats and Roosting Spots
Hoary wattled bats often live in woodlands, open forests, and areas near water sources. They need these places to find food and shelter. During the day, they rest, or roost, in safe, hidden spots. These can include tree hollows, under loose bark, or sometimes even in abandoned buildings. Roosting sites protect them from predators and the heat of the day.
What Do Hoary Wattled Bats Eat?
Like most bats, the hoary wattled bat is an insectivore. This means its diet consists mainly of insects. They are expert hunters of flying insects. They catch their prey while flying through the air.
How They Hunt in the Dark
These bats are nocturnal, meaning they are active at night. They use an amazing ability called echolocation to hunt. Echolocation is like having built-in sonar. The bat sends out high-pitched sounds. These sounds bounce off objects, creating echoes. The bat then listens to these echoes to create a detailed sound map of its surroundings. This helps them find tiny insects in complete darkness. Their diet includes moths, beetles, and other small flying insects.
Bat Behavior and Lifestyle
Hoary wattled bats are generally solitary creatures. Sometimes, you might find them in small groups. They emerge from their roosts at dusk to begin their nightly hunt. Their flight is fast and agile, allowing them to chase down quick-moving insects.
Social Habits and Daily Routine
During the day, these bats sleep soundly in their roosts. They hang upside down, a common bat behavior. This position helps them launch quickly into flight when it's time to hunt. Their social interactions are not as complex as some other bat species. They mostly focus on finding food and raising their young.
Life Cycle and Reproduction
The reproduction of hoary wattled bats is an important part of their life cycle. Female bats usually give birth to one or two pups at a time. This typically happens during the warmer months when food is plentiful.
Raising Young Bats
Baby bats, called pups, are born tiny and helpless. They rely completely on their mother for milk and protection. The mother bat cares for her pups in the roost. She feeds them until they are old enough to fly and hunt on their own. This period of growth and learning is crucial for the young bats' survival.
Protecting Hoary Wattled Bats
The hoary wattled bat is currently listed as "Least Concern" by the International Union for Conservation of Nature (IUCN). This means their populations are stable for now. However, it's still important to protect them and their habitats.
Why Bats Are Important
Bats play a vital role in their ecosystems. By eating vast numbers of insects, they help control insect populations. This is good for agriculture and reduces the spread of insect-borne diseases. Protecting bats means protecting a healthy environment for everyone. We can help by preserving their natural habitats and reducing pesticide use.
