Overview

About Kentucky

Kentucky's wildlife comes from a mix of lands: rolling Bluegrass, Appalachian ridges and plateaus, and wide river valleys with intact temperate forests. These places are home to white-tailed deer, wild turkey, black bear, many migratory songbirds, and rich freshwater life in clean streams and rivers. Karst areas like Mammoth Cave and other caves give bats and cave-adapted invertebrates important roosting and hibernation homes. Sinkholes, springs, and underground streams link surface forests to hidden waters. The Appalachian Plateau and Cumberland Mountains hold large oak-hickory forests for interior-forest birds and many mammals. Along the Ohio, Green, Kentucky, Cumberland, and Tennessee rivers, backwaters, sloughs, and riffles support diverse fish and mussels. Kentucky is known for how quickly the wildlife mix changes over short distances—from Bluegrass hedgerows and grasslands to cave country, ridge forests, and river-bottom wetlands with herons and amphibians.

Physical Features

Geography

Kentucky's wildlife reflects a shift from the forested, rugged Appalachian and Cumberland highlands in the east to rolling, limestone-based Bluegrass hills and karst plains in the center, then to broad river floodplains and wetlands in the west. Large hardwood forests, cave and spring systems, and big rivers support forest animals, cave animals, and many freshwater fish and mussels.

Endemic & Rare Species

Kentucky Cave Shrimp

Palaemonias ganteri

Federally Endangered (U.S.); extremely restricted cave-range

A globally rare crustacean confined to a small area of the Mammoth Cave region; highly sensitive to groundwater quality and hydrologic changes.

Kentucky Cavefish

Amblyopsis spelaea

Range-restricted cave specialist; conservation concern in parts of its range

A signature cave-adapted fish of central Kentucky karst systems; an important indicator of groundwater ecosystem health.

Indiana Bat

Myotis sodalis

Federally Endangered (U.S.); heavily impacted by white-nose syndrome

Kentucky caves and forests support critical habitat (hibernation and summer roosting); the species' steep regional declines make remaining sites especially important.

Gray Bat

Myotis grisescens

Federally Endangered (U.S.); cave-roosting specialist

Kentucky's cave country includes significant roosting/hibernation habitat; protecting cave entrances and surrounding foraging waters is key to recovery.

Fanshell (freshwater mussel)

Cyprogenia stegaria

Federally Endangered (U.S.)

A highly imperiled mussel of larger rivers (historically in the Ohio and tributaries); emblematic of Kentucky's exceptional but vulnerable mussel diversity.

Northern Riffleshell (freshwater mussel)

Epioblasma rangiana

Federally Endangered (U.S.)

Once widespread in river shoals; now restricted to a few systems. Kentucky is part of the species' remaining stronghold landscape in the Ohio River basin.

Cumberland Darter

Etheostoma susanae

Vulnerable/imperiled (regional); Species of Greatest Conservation Need in Kentucky

A small, colorful fish tied to clean, flowing tributaries of the Cumberland River system; threatened by sedimentation, impoundments, and habitat fragmentation.

Eastern Hellbender

Cryptobranchus alleganiensis

Declining across much of its range; state conservation concern

A large, fully aquatic salamander that requires cold, clean, rocky streams-an iconic Appalachian indicator species sensitive to siltation and water quality changes.

Notable Populations

  • One of the largest elk populations in the eastern United States (reintroduction begun in the late 1990s; centered in eastern Kentucky).
  • Globally significant cave biodiversity centered on the Mammoth Cave karst system, including rare groundwater shrimp and cavefish, plus major bat use of cave habitats.
  • Nationally important freshwater biodiversity in the Ohio-Cumberland-Tennessee-Green river networks, with high richness of fish and imperiled freshwater mussels in the Ohio River basin context.
  • Strong bald eagle nesting and wintering presence along large reservoirs and major rivers (notably Kentucky Lake/Lake Barkley and the Ohio River corridor).
  • Regionally significant migratory and wintering bird concentrations on western Kentucky wetlands, refuges, and reservoirs within the Mississippi Flyway influence zone.

Recent Changes

  • Elk reintroduction (starting 1997) succeeded, establishing a large, widely viewed herd and expanding wildlife tourism in eastern Kentucky.
  • Bald eagles have rebounded and expanded nesting following DDT-era declines, with increasing occupancy along major waters.
  • River otters were reintroduced (1990s) and have reestablished in many watersheds where habitat and water quality support them.
  • American black bears have increased and expanded their range in eastern Kentucky, with more frequent reports in and near Appalachian forests.
  • White-nose syndrome has driven major declines in several cave-hibernating bat species (including Indiana bat), making cave protections and disturbance management more urgent.
  • Chronic Wasting Disease (CWD) has been detected in Kentucky in recent years, prompting expanded monitoring and management actions for cervids.
  • Freshwater mussels and some sensitive stream fishes continue to face localized declines from legacy and ongoing stressors (dams/impoundments, sedimentation, altered flows, and water quality impacts).

Wildlife Viewing

Kentucky offers wildlife viewing across Bluegrass farmland, hardwood forests, Appalachian ridges, wetlands, and karst caves. Expect good birding at migration, big bat emergences in summer, and elk in the east. Rivers, lakes and the Ohio River hold otters, beavers, turtles and waterfowl. Many spots are in state parks, national recreation areas, and wildlife management areas with trails and overlooks.

Best Seasons

Spring (Mar-May)

Peak songbird migration (warblers, vireos, thrushes) and wildflower season in forests and gorges. Wetlands and lake edges fill with waterfowl and wading birds. Amphibians are active after rains, and dawn birding is especially productive in western Kentucky's river bottoms and in the Red River Gorge region.

Summer (Jun-Aug)

Best time for iconic bat viewing at Mammoth Cave (evening emergence programs when scheduled). Forest wildlife is active at dawn/dusk; look for deer, wild turkey, and reptiles near rocky glades. Lakes and rivers offer reliable sightings of herons, kingfishers, turtles, beavers, and occasional river otters. Night walks can add owls, whip-poor-wills, and fireflies.

Fall (Sep-Nov)

Prime season for elk viewing during the rut in the Appalachian coalfield region (bugling and herd activity). Excellent fall raptor and songbird migration along ridges and open country. Mast (acorns) draws turkey and deer into hardwood forests. Cooler temperatures make long hikes in Red River Gorge, Big South Fork, and Daniel Boone National Forest more comfortable.

Winter (Dec-Feb)

Best waterfowl season in western Kentucky-large concentrations of ducks and geese on lakes, refuges, and flooded fields. Bald eagles are more likely near major rivers and reservoirs. With leaf-off conditions, woodland birding (woodpeckers, sparrows) improves and wildlife is easier to spot along edges and open habitats.

Top Wildlife Experiences

  • Watch an evening bat emergence (seasonal programs) at Mammoth Cave National Park-arrive early for ranger-led interpretation and stay for dusk flights.
  • Go elk-watching at dawn or dusk in the Kentucky Elk Viewing Area (southeastern Kentucky) during September-October for rut activity; use designated pull-offs and viewing sites.
  • Bird the wetlands and lakes around Land Between the Lakes National Recreation Area (western KY) for waterfowl, shorebirds, and raptors; plan sunrise at a bay or marsh edge.
  • Scan for bald eagles and wintering waterfowl along the Ohio River corridor-especially near large reservoirs and backwaters in western Kentucky during Dec-Feb.
  • Hike to overlooks in Red River Gorge Geological Area (Daniel Boone National Forest) for raptors, forest songbirds, and chances at deer and turkey; pair with early-morning trailheads for best activity.
  • Paddle or take a quiet shoreline walk at Lake Cumberland State Resort Park or Barren River Lake State Resort Park to look for herons, kingfishers, turtles, beavers, and signs of river otters.
  • Take a guided cave tour in Kentucky's karst country (Mammoth Cave region) to learn about cave-adapted ecosystems and view cave formations while connecting the underground landscape to surface wildlife habitats.

Habitats

Ecosystems

Kentucky includes the Appalachian Plateau (east), rolling Bluegrass (center), knob-and-ridge belts, and the Mississippi Embayment/Jackson Purchase (west), giving high ecosystem diversity. Most land is temperate broadleaf forest and a mix of forests and farms. It has karst landscapes like Mammoth Cave, major river habitats (Ohio, Kentucky, Cumberland, Tennessee), and wetlands and bottomland forests in the west.

Biomes

Temperate Forest

Dominant biome statewide, largely oak-hickory and mixed mesophytic hardwood forests with rich coves in the east and oak-maple/beeches and riparian hardwoods elsewhere; includes scattered pine and hemlock components on drier or cooler sites.

Primary natural biome across most of Kentucky; most continuous in eastern and south-central uplands, fragmented by agriculture in the Bluegrass and western lowlands.

Temperate Grassland

Occurs mainly as anthropogenic grasslands (pastures/hayfields) plus small remnants of native prairie/grassland communities (e.g., barrens/old fields and glades) in drier, open sites.

Patchy; most extensive as managed pasture in central Kentucky and portions of the west; native remnants are small and localized.

Freshwater

Large river systems (Ohio, Cumberland, Kentucky, Green, Licking, Salt, Big Sandy, and others), reservoirs (e.g., Kentucky Lake, Lake Barkley, Laurel River Lake), plus springs/seeps strongly influenced by karst hydrology.

Statewide along major river corridors and reservoir basins; dense stream networks in the Appalachians and karst regions.

Wetland

Bottomland hardwood wetlands, oxbows, sloughs, floodplain marshes, and cypress-tupelo swamp pockets primarily in the Jackson Purchase and along the Ohio and Mississippi floodplains; also beaver wetlands and emergent marshes around reservoirs.

Concentrated in far western Kentucky and major floodplains; smaller scattered wetlands elsewhere (often along rivers, impoundments, and beaver complexes).

Habitats

Forest

Extensive temperate forest cover including upland oak-hickory, mixed mesophytic forests in the Appalachians, and riparian forests along major rivers; major blocks in Daniel Boone National Forest and surrounding uplands.

Deciduous Forest

Hardwood-dominated stands (oak, hickory, maple, beech, tuliptree) common across uplands and rolling hills; rich cove forests in the east support high plant diversity.

Coniferous Forest

Localized pine (e.g., shortleaf/virginia pine) on dry ridges and reclaimed lands; eastern hemlock pockets in moist gorges where not impacted by hemlock woolly adelgid.

Woodland

Open-canopy oak woodlands and savanna-like barrens/glades occur on dry slopes and thin soils, especially in parts of south-central Kentucky and the Knobs region.

Grassland

Widespread managed pasture and hayfields (notably the Bluegrass region), with small native grassland remnants and old-field successional grasslands.

Shrubland

Early-successional shrub thickets on disturbed lands, old fields, utility corridors, and edge habitats; important for some songbirds and pollinators.

Mountain

Rugged, dissected terrain of the Cumberland Plateau/Appalachian region in eastern Kentucky, with steep forested ridges, hollows, and high-gradient streams.

Cliff/Rocky Outcrop

Sandstone cliffs, rockhouses, and gorges especially in the Red River Gorge/Daniel Boone region; provide nesting ledges and unique cliffline plant communities.

Cave

World-class karst and cave systems (Mammoth Cave and extensive karst statewide), supporting specialized subterranean fauna, bat roosts, and unique groundwater ecosystems.

River/Stream

Major navigable rivers (Ohio, Cumberland, Tennessee/Lower Tennessee, Kentucky, Green) and many smaller rivers/creeks; critical habitat for diverse freshwater fishes and mussels.

Lake

Large reservoirs (Kentucky Lake, Lake Barkley, Rough River Lake, Barren River Lake, Laurel River Lake) and natural floodplain lakes/oxbows in western lowlands.

Pond

Farm ponds and small impoundments common in agricultural landscapes; provide amphibian and waterfowl habitat but vary in water quality and connectivity.

Wetland

Floodplain wetlands, emergent marshes, wet meadows, and beaver wetlands; strongest wetland complexes in the Jackson Purchase and along major river bottoms.

Swamp

Cypress-tupelo and backwater swamp habitats occur in far western Kentucky (Mississippi Embayment influence), especially in protected lowlands and slough systems.

Marsh

Emergent marshes around river backwaters and reservoir margins (notably western Kentucky) that support waterfowl, wading birds, and amphibians.

Bog

Rare and localized acidic seep/bog-like wetlands and fens (often small), occurring where hydrology and soils allow; much more limited than in northern states.

Urban

Urban habitats centered around Louisville, Lexington, Northern Kentucky/Cincinnati metro fringe, and smaller cities; includes riverfront corridors and urban parks.

Suburban

Expanding suburban matrices around major metros, creating fragmented forest patches, edge habitats, and altered stream hydrology.

Agricultural/Farmland

Extensive cropland and pasture (corn/soy/hay, tobacco historically) especially in the Bluegrass and western lowlands; interspersed with woodlots and riparian strips.

Ecoregions

EPA Level III ecoregions (Kentucky): Central Appalachians; Southwestern Appalachians; Western Allegheny Plateau; Interior Plateau; Interior River Valleys and Hills; Mississippi Alluvial Plain; Southeastern Plains WWF terrestrial ecoregions (present in Kentucky): Appalachian mixed mesophytic forests; Central U.S. hardwood forests; Western Allegheny Plateau forests; Mississippi lowland forests
Protection

Conservation

Primary Threats

  • Fragmentation of hardwood forests and loss of riparian buffers from development, road building, and some timber conversion reduces interior-forest habitat and degrades stream shading/structure; wetland and floodplain habitat loss along river corridors affects waterfowl, amphibians, and fish spawning/nursery areas.
  • Fertilizer and soil runoff from row crops and pasture in the Bluegrass and western Kentucky cause algae blooms and murky water. Old and active mining in eastern Kentucky adds sediment and metals. City stormwater and sewage overflows harm at-risk mussels and sensitive fish.
  • Coal mining (including legacy impacts) in Appalachian headwaters can bury/alter streams, increase fine sediment loads, and change water chemistry; valley fills and degraded headwater networks reduce habitat for stream salamanders, darters, and mussels downstream.
  • Dams, impoundments, channelization, and altered flow regimes in major rivers and reservoirs (e.g., navigation and flood-control systems) disconnect floodplains, change temperature/oxygen patterns, and simplify habitat-key drivers of mussel and migratory fish declines in the Ohio and Cumberland/Tennessee systems.
  • Aquatic invasives such as zebra mussels and Asian carp affect food webs and compete with native mussels/fishes in large rivers and reservoirs; terrestrial invasives like bush honeysuckle and kudzu alter understory structure and regeneration in forests and edges, reducing habitat quality for native birds and pollinator communities.
  • White-nose syndrome has severely reduced hibernating bat populations in Kentucky's extensive cave systems; because Kentucky hosts major hibernacula, disease impacts can be regionally significant and complicate cave-management decisions (gating, access restrictions, decontamination).
  • More intense rainfall events increase flashiness and erosion in karst and Appalachian headwaters, stressing mussels and spawning fishes; warmer winters can disrupt bat hibernation energetics and shift species ranges; hotter, drier late-summer periods can reduce baseflows, shrinking habitat in small streams and springs.
  • Conversion or intensification of pasture and cropland reduces native grasslands/early successional habitat and increases pesticide/nutrient inputs; removal of streamside vegetation for grazing access accelerates bank erosion and directly degrades mussel and fish habitat.
  • Growth around Louisville, Lexington, Northern Kentucky (Cincinnati metro), and regional hubs increases impervious cover, traffic mortality, and stream 'flashiness'; suburban expansion fragments forest patches and increases human pressure on nearby wildlife areas and caves.
  • Roads, pipelines, and utility corridors fragment forests and create chronic sediment sources at stream crossings; bridge/culvert barriers can limit fish passage in smaller tributaries; expanded navigation/river infrastructure can further simplify big-river habitats used by imperiled fishes and mussels.
  • While much forestry is managed, poorly timed or poorly buffered harvests can increase sediment delivery to headwater streams and reduce mature-forest structure important for roosting bats and forest interior birds, particularly in portions of the Cumberland Plateau and adjacent regions.
  • Recreation pressure in caves and on sensitive clifflines/river corridors can disturb bats during hibernation or maternity periods and affect nesting raptors; off-road vehicle use in some areas increases erosion and direct habitat damage, especially on fragile karst and steep Appalachian soils.
  • Expanding black bear populations in eastern Kentucky and suburban-adjacent areas can lead to conflicts (garbage, feeders, small livestock), increasing calls for removal; deer-vehicle collisions and localized crop damage create pressure for higher harvests and can affect public tolerance for wildlife.
  • Kentucky's regulated hunting is generally sustainable, but localized overharvest risk or misaligned harvest goals can affect deer structure and ecosystem impacts (browse pressure on forest regeneration); illegal take remains a periodic concern for certain species.
  • Localized over-collection pressure can affect baitfish, crayfish, and herpetofauna in sensitive streams; chronic habitat degradation also reduces 'biological resources' (e.g., mussel recruitment), effectively depleting native aquatic communities even without direct harvest.
Fun Facts

Did You Know?

Kentucky has "fish that are born into darkness": the Northern cavefish (Amblyopsis spelaea), found in Kentucky's karst groundwater, is blind and pale-and females brood eggs/young in a protected chamber rather than scattering eggs like most fish.

Mammoth Cave shelters species found essentially nowhere else, including the endangered Kentucky cave shrimp (Palaemonias ganteri), a translucent crustacean adapted to permanent darkness and nutrient-poor subterranean streams.

Far western Kentucky's swamps and big rivers support animals many people don't associate with the state at all-such as the alligator snapping turtle (Macrochelys temminckii), one of North America's heaviest freshwater turtles.

Kentucky's "underground rivers" create above-ground wildlife effects: sinkholes, springs, and disappearing streams can move nutrients and organisms between surface creeks and cave waters, linking forest, river, and cave food webs in ways that don't happen in most landscapes.

You can hear the state's modern "wild comeback" in fall: elk bugles now echo across southeastern Kentucky-an experience that would have been impossible for most of the 20th century after elk were extirpated from the region.

Mammoth Cave National Park contains the world's longest known cave system-over 426 miles (686+ km) of mapped passages-creating one of Earth's largest continuous habitats for cave-adapted wildlife.

Kentucky supports the largest elk (wapiti) population east of the Mississippi River; since reintroductions began in 1997, the herd has grown to roughly 10,000+ animals centered in the state's Appalachian coalfields.

Kentucky is a national freshwater hotspot: it's commonly ranked among the top U.S. states for native freshwater fish diversity (roughly 240-250 species), boosted by the Ohio River corridor and multiple Appalachian/Mississippi-draining watersheds.

The state is also a freshwater mussel stronghold-Kentucky has 100+ native mussel species, placing it among the top few states for mussel diversity, with the Green River system recognized as one of North America's richest temperate mussel rivers.

Carter Caves State Resort Park's "Bat Cave" is recognized as one of the larger bat hibernation sites in the eastern U.S., highlighting how Kentucky's karst landscape concentrates huge numbers of cave-roosting bats in winter.

Kentucky located in the United States has a diverse landscape that includes mountains, lakes, rivers, wetlands, forests, and even caves. So, it’s not surprising that the state is home to a variety of mammals, insects, birds, reptiles, and amphibians.

Some of the most well-known wild animals in Kentucky include the little brown bat, black bear, sandhill crane, Kentucky warbler, copperhead snake, eastern box turtle, and largemouth bass.

The Official Animal of Kentucky

Kentucky has a few different official state animals that help to represent the wide variety of wildlife there. Check out some of the official animals of Kentucky.

Official Mammal of Kentucky: Thoroughbred Horse

The thoroughbred horse is Kentucky’s state animal

Though these are not wild animals, they are considered treasures in the state of Kentucky. The state is home to many thoroughbred farms and breeding programs. This horse became the official mammal of the state in 1996. Since 1875, this midwestern state has hosted the Kentucky Derby horse race on the first Saturday in May every year.

The Kentucky Derby attracts racing fans and horse owners from across the globe. One of the most famous horses to win the Kentucky Derby was Secretariat. Secretariat won the Derby in 1973 when the 99th running of the race took place.

Official State Bird of Kentucky: Northern Cardinal

Northern Cardinal in flight

It is the male Northern Cardinal which is known for its beautiful scarlet plumage. The female’s on the other hand happens to be a drab brown with a few touches of red

Back in 1926, the northern cardinal became the state bird of Kentucky. They are a familiar sight at backyard bird feeders and birdbaths all over the state. The bright red feathers of a male northern cardinal along with the distinctive mask of black feathers on its face make this bird hard to overlook! The female cardinal bears a resemblance to the male with the tuft of feathers on its head.

However, the female is duller in color with brownish-gray feathers and a few splotches of red. This bird has a distinctive song that sounds similar to the words, ‘cheer, cheer, cheer’ or ‘birdie, birdie, birdie.’ As a note, the popularity of this memorable bird has earned it the honor of being the state bird of 7 states in the U.S.!

Official Fish of Kentucky: Kentucky Spotted Bass

Spotted Bass

The spotted bass has a lifespan of about six years

In 1956, Kentucky spotted bass became the official fish of this state. These fish are a common sight in clear streams, lakes, and reservoirs throughout Kentucky. They seem to have a preference for water which their smallmouth counterparts would find too warm for comfort. They have a lifespan of about six years and can mate with smallmouth bass as evidenced by the hybrids which have been spotted.

A female can lay up to 47,000 eggs at one time. The male swims around the eggs to keep watch over them until they hatch. With all of those eggs hatching in streams and rivers, it’s not hard to believe that the conservation status of this fish is Least Concern. The spotted bass is far from the only variety of this highly popular fish to be found in the Bluegrass State. Additional varieties include largemouth, smallmouth, striped, and white.

Where to Find the Top Wild Animals in Kentucky

Little brown bats can be admired in Mammoth Caves

Visitors to Kentucky have the opportunity to see lots of different types of wildlife. Naturally, the types of wild animals a person sees depend on where they travel in the state.

People who visit Mammoth Caves in Kentucky can see unique wildlife such as little brown bats, cave salamanders, and Kentucky cave shrimp. The strange eyeless fish is another cave-dwelling animal in Kentucky. Some visitors may be lucky enough to catch a glimpse of the endangered Indiana brown bat.

The forests of Kentucky are home to white-tail deer, rabbits, American toads, coyotes, opossums, squirrels, skunks, and foxes. Rodents including mice, pine voles, and eastern woodrats are other forest dwellers.

Rivers in Kentucky are home to flathead catfish, spotted bass, white bass, walleye, and bluegills among others. The variety of fish in the rivers and lakes of Kentucky makes it a popular state for amateur and seasoned fishermen alike.

Kentucky’s wetlands serve as the habitat for common snapping turtles, alligator gar, swamp darters, masked shrews, Kirtland’s snake, and the heron.

Mountains in Kentucky such as the Appalachian Mountains are home to elk, black bears, whitetail deer, beaver, weasels, and chipmunks.

What Does a Copperhead Snake Look Like

In spite of their venom, copperheads are not aggressive and prefer to blend in with their environment when they feel threatened

As with most states, Kentucky has some wild animals and native wildlife that are considered dangerous. Discover a few of the most dangerous animals in Kentucky.

Snakes in Kentucky

Cottonmouths unlike copperheads are aggressive and will respond to any encroachment of their territory; their venom is pretty potent and dangerous to humans

There are more than 30 types of snakes found in Kentucky, of which four are venomous.

The copperhead snake is one of the most dangerous animals in Kentucky. It is one of several venomous snakes living in the state. Copperhead snakes get their name from the copper-colored pattern of their scales. As an adult, this reptile can reach a length of up to four feet. Keep in mind that they are not known to be aggressive and usually remain still in order to blend in with their forest habitat when they detect a threat.

A common reaction of this snake is to vibrate its tail to warn predators or other threats to move away. It uses its venom to kill rodents and other prey. Fortunately, its venom is not strong enough to kill a human. But this doesn’t mean its bite is not painful! Anyone who is bitten by a copperhead snake should seek medical treatment as soon as possible.

The cottonmouth is another snake that makes the list of Kentucky’s most dangerous wild animals. This snake gets its name from the white interior of its mouth. It has a strange habit of allowing its mouth to gape open when threatened by predators. This bright white (along with its fangs) are meant to scare away the threat. Unlike the copperhead, the cottonmouth snake is aggressive to wildlife and people who walk into its territory. Of course, most people don’t know when they are walking into this snake’s territory!

These snakes grow to a length of three to four feet. The venom of a cottonmouth is very powerful and is potentially deadly to a human. Fortunately, cottonmouth snake bites aren’t common and account for less than one percent of all the snake bites recorded in the United States each year. Keep in mind that medical attention is needed right away after being bitten by a cottonmouth snake.

Bears in Kentucky

Black Bear Population by State

Black bears can be particularly aggressive if they happen to be caring for cubs

Black bears are also known as some of the most dangerous animals in Kentucky today. Though it’s common for these mammals to stay away from people, they can become aggressive especially when their cubs are in the area. They are very protective animals. These are strong bears; they have sharp claws and can weigh up to 600 plus pounds. Fortunately, black bear attacks are really rare. These mammals are more likely to get into a fight with a domesticated dog they meet in the woods than attack a human.

Spiders in Kentucky

Deadliest Animals in America

Black widow venom can cause breathing difficulties, pain, nausea, and sweating and always requires medical attention

Kentucky is home to many species of spiders from jumping spiders, to orb weavers, to spiders with dangerous bites that contain venom.

Black widow spiders are among some of the most dangerous wildlife in Kentucky. The female black widow spider is black with a distinctive design in red or yellow on its abdomen. It’s venomous and lives under porches and in corners of garages and sheds. They normally make their web in places where they aren’t likely to encounter people.

Though their venom is powerful enough to kill their prey of flies, grasshoppers, and beetles, human death is the rarest result. In fact, there have been no recorded deaths from a black widow’s bite since the 1980s. However, they are most likely to bite someone when they reach into a dusty corner of a garage or shed without realizing the spider and its web are there. This spider’s bite can make a person ill causing swelling, pain, difficulty breathing, nausea, sweating, and other symptoms. Medical treatment is necessary for anyone bitten by this venomous spider.

The Largest Animal in Kentucky

bison

Bison once roamed North America in their numbers until they were hunted to extinction. Today, they can be admired in Kentucky in Big Bone Lick State Park

The title of largest animal in the Bluegrass State, goes to the bison. The massive herbivore known for its large shaggy head is a case of deceiving appearances. The towering bovine is actually a gifted athlete and is not only a strong swimmer but is also capable of reaching speeds of 35 – 40 mph. Most surprising of all is its ability to defy gravity and clear 6 feet in a single leap.

Those abilities become all the more impressive given the fact that bison are capable of reaching 6 feet in height, and tipping the scales at 2,000 lbs. They once roamed the region in their numbers until they were hunted to extinction. The last native bison was seen in Kentucky in the 19th century.

Today these bovine giants can be admired at Big Bone Lick State Park where they are hailed as being the only living connection to the Ice Age.

The Rarest Animal in Kentucky

About 500 whooping cranes exist in the wild in the United States

Kentucky’s rarest animal is pretty heavy and is capable of weighing 16 pounds. It’s also pretty tall, too and has been known to reach heights of 5 feet 3 inches. Known as the whooping crane it is actually the tallest bird in the United States. It can be recognized by its white plumage, a dark slender beak, and a red cap which seems to extend from its beak.

The United State’s eastern population which is made up of about 100 birds, tends to pass through western Kentucky on journeys between Wisconsin and Florida. The national population of whooping cranes is believed to be about 500. Hunting these large, majestic avians is prohibited.

Endangered Animals in Kentucky

Myotis grisescens, gray bat

The gray bat is currently threatened as a result of habitat loss

Kentucky Endangered animals include:

  • Cumberland Darter – This fish grows to be about two inches long and is a member of the perch family. It’s found in streams and in shallow pools. They are threatened by water pollution and habitat loss in Kentucky.
  • Whooping Crane – This is the tallest bird in North America and has a seven-and-a-half-foot wingspan. Though this bird’s population is increasing, it is still one of the rarest sights in the Bluegrass state. There are just 50 to 249 mature individuals in existence. Loss of their wetland habitat is one reason why these birds are categorized as Endangered.
  • Blackside Dace – This fish grows to a length of three inches and is found in the Cumberland River system. It has green and gold scales with bright yellow fins. Habitat loss and water pollution have contributed to the decreasing population of this fish.
  • Rusty Patched Bumble Bee – These bees get their name from the rusty-colored patch of hair on their back. Their habitat is the grasslands and prairies. Unfortunately, these bees are one of the rarest sights in the state. Their population is decreasing in Kentucky and elsewhere due to habitat loss, the use of pesticides on vegetation and farming activity. They have a conservation status of Critically Endangered.
  • Gray Bat – Their name refers to the layer of dark gray fur they have all over their bodies. These bats live in caves over the course of the entire year. This is different than many other species of bats that live in barns, attics and under bridges. They are a federally endangered species due to habitat loss. When caves flood naturally or because of the presence of a nearby reservoir these bats lose their only shelter. If a gray bat loses its cave habitat (especially during the cold weather months) it has to expend a lot of energy looking for new shelter. This can cause a bat to become ill or even die.
  • Indiana Bat – Though it is named after another state, this bat lives in caves and trees in Kentucky. The reason it is categorized as Endangered in Kentucky is mostly due to loss of habitat. When an entrance to a cave is blocked for the winter, these bats have fewer places to take shelter. Another threat to the Indiana bat is known as white-nosed syndrome. It’s a deadly disease caused by a fungus that thrives in the cold temperatures of caves. This syndrome affects bats and other animals that hibernate in caves in North America.

Native Plants in Kentucky

Willow Oak

Kentucky is home to several native tree and shrub species including willow oak

Trees native to Kentucky include black cherry, black walnut, blue ash, bur oak, green ash, Kentucky coffeetree, pin oak, red maple, sassafras, sycamore, and willow oak. Shrubs include bluestar, fragrant sumac, spice bush, wild hydrangea, winterberry.

The Flag of Kentucky

Flag of Kentucky

The flag of Kentucky was designed by Jesse Cox Burgess an art teacher

Kentucky’s state flag has rich blue background against which its seal stands. The seal itself depicts two men, one a frontiersman (on the left) and the other a statesman (on the right), greeting each other warmly. The words “United We Stand”, are placed above the men, while the words, “Divided We Fall”, are placed below them.

The lower half of the seal itself is framed with the golden rod which itself is the official state flower of Kentucky, while the upper half is framed with the words “Commonwealth of Kentucky”, in yellow uppercase lettering. The flag was designed by art teacher Jessie Cox Burgess and subsequently adopted by the State General Assembly in 1918.
