10 Types of Bats in Kentucky

What are the most common bats in Kentucky?

Kentucky hosts around 16 bat species, each playing a vital role in the local ecosystem. The big brown bat (*Eptesicus fuscus*) is the most frequently encountered, often roosting in buildings and barns with a wingspan of 12 to 16 inches and reddish brown fur. The little brown bat (*Myotis lucifugus*) is smaller, with a wingspan of 8 to 11 inches and glossy brown fur, though its numbers have faced challenges recently. Evening bats (*Nycticeius humeralis*) are also common, particularly in the western part of the state where they inhabit forest edges. The hoary bat (*Lasiurus cinereus*) stands out as the largest species in the state, featuring beautiful frosted fur and a wingspan that can reach up to 16 inches.

How can I tell bats apart from similar looking animals?

Bats are the only true flying mammals, which makes them unique among Kentucky's wildlife. Their wing membranes, known as the patagium, stretch from elongated fingers to the body and legs, unlike birds which rely on feathers for flight. Flying squirrels glide but do not actually flap their wings to gain altitude. Swifts and nighthawks fly differently as well. Bats have an erratic, fluttering flight pattern as they hunt insects, while birds generally glide more steadily. Bats also have visible ears and a short tail that is often tucked into the tail membrane. For more on lookalikes, see ourKentucky wildlife page.

Where in Kentucky do people usually spot bats first?

Bats are most often seen near water sources like lakes, rivers, and streams where insects are plentiful. Mammoth Cave National Park is a major bat roost and offers some of the most famous viewing opportunities in the world. However, many bats also forage in state parks such as John James Audubon, Natural Bridge, and Cumberland Falls. Bridges, barns, and even old silos are common day roosts for various species. Urban areas with streetlights often attract insects, which in turn attract bats at dusk. Start atMammoth Caveor any wooded trail near water for the best odds of a successful sighting.

What time of year is best for bat watching in Kentucky?

Bats typically emerge from hibernation in mid April and remain active through October. The best sightings usually occur from May to August when maternity colonies are active and young bats are learning to fly. Evening is the prime time for observation. It is best to start looking 15 to 30 minutes after sunset on warm, calm nights. In the fall, particularly during September and October, bats swarm near cave entrances before heading into hibernation, which can offer concentrated viewing of multiple species at once.

What field marks should I rely on for identification?

Key field marks include forearm length, which measures 38 to 50 mm for big brown bats and 35 to 40 mm for little brown bats. Fur color and texture can also be helpful, as can ear shape and the presence of a tragus, which is the fleshy projection inside the ear. The calcar, a small bone or cartilage that supports the tail membrane, helps separate certain species. Flight patterns are another useful indicator. Big brown bats tend to fly straight and fast, while little brown bats flutter more erratically. Using a headlamp with a red filter and binoculars can provide better views without disturbing the animals.

Are there any endangered bat species in Kentucky?

Yes, Kentucky is a critical habitat for several endangered species, including the Indiana bat (*Myotis sodalis*) and the gray bat (*Myotis grisescens*). The Indiana bat is known for forming large hibernating clusters in caves during the winter. Gray bats are unique because they use caves year round for both roosting and raising young. These species are highly sensitive to disturbance and habitat loss. White nose syndrome, a fungal disease, has also severely impacted many populations. Conservation efforts in Kentucky focus on protecting cave entrances and preserving the forested areas where these bats forage for insects during the summer months.

How do Kentucky bats spend the winter months?

During the winter, most Kentucky bats enter a state of hibernation called torpor to survive the cold and the lack of insects. They seek out hibernacula, which are usually caves or abandoned mines where temperatures remain stable and above freezing. Caves like those found in the karst regions of central Kentucky provide the perfect environment for species like the big brown bat and the tri colored bat. Some species, like the hoary bat and the silver haired bat, may migrate south to warmer climates instead of hibernating locally. It is vital to avoid entering caves during the winter to prevent waking bats from their torpor, which can cause them to burn through their fat reserves too quickly.

What should I do if I find a bat on the ground in Kentucky?

If you find a bat on the ground, it is important to remember that it may be injured, sick, or simply exhausted. Never handle a bat with your bare hands. If the bat is in a safe place, it is often best to leave it alone. If it needs to be moved for its safety, use a thick pair of gloves or a small box to gently relocate it to a nearby tree or elevated surface where it can take flight. If the bat appears sick or is in a high traffic area, contact a local wildlife rehabilitator or the Kentucky Department of Fish and Wildlife Resources. Protecting yourself and the bat is the priority in these situations.

Can I attract bats to my backyard in Kentucky?

Yes, you can attract bats by installing a bat house on a pole or a building at least 10 to 15 feet high, preferably facing south or southeast to catch the sun. Bat houses offer safe roosting sites for bats that in turn help control insect populations in your yard. It is also helpful to provide a nearby water source and to avoid the use of pesticides, which can reduce the food supply for bats. Planting night blooming flowers that attract moths can also make your backyard more appealing to foraging bats. For more setup tips, see ourbat conservation resources.

Frequently asked questions about Kentucky bats

**Are bats in Kentucky dangerous?** Bats are not aggressive and will generally avoid humans whenever possible. However, you should never handle a bat, as a small percentage can carry rabies. If you find one on the ground, it is best to contact a wildlife rehabilitator.

**Do all bats in Kentucky eat insects?** Yes, all 16 species of bats found in Kentucky are insectivores. They play a crucial role in controlling populations of mosquitoes, moths, and beetles that can damage crops and gardens.

**How many bats live in Mammoth Cave?** Thousands of bats use Mammoth Cave and the surrounding cave systems seasonally. This includes several species of conservation concern, making the area one of the most important bat habitats in the eastern United States.

**Can I see bats during the day?** It is rare to see bats active during the day unless they have been disturbed from their roost. You might spot them hanging in buildings, under bridges, or in the rafters of barns, but they are most active after sunset.

**What should I do if a bat flies inside my house?** If a bat enters your home, open all exterior doors and windows and turn off the indoor lights. This allows the bat to use its echolocation to find its way back outside without further stress.
