Overview

About Oklahoma

Oklahoma is a wildlife crossroads where dry Great Plains prairies meet the Cross Timbers oak woodlands and then the greener hills and forests of the east. This west-to-east change brings prairie animals like pronghorn and prairie chickens and grassland birds, plus forest animals like white-tailed deer, wild turkey, and woodland songbirds. Major migratory flyways and rivers and reservoirs make the state a year-round place for birders and big-game watchers. Shortgrass and mixed-grass prairies support prairie chickens, raptors, and mammals that travel far. The Cross Timbers—patches of post oak and blackjack oak—shelter deer, bobcats, and many woodland birds. In the east, the Ouachita foothills add an Appalachian feel. Riparian corridors along the Cimarron, Canadian, and Red rivers act as green highways for migrating waterfowl and songbirds. Sharp habitat shifts let you see western and eastern species in one trip.

Physical Features

Geography

Oklahoma has west–east rain and elevation changes that create different habitats. Shortgrass prairie and the High Plains in the Panhandle support prairie specialists like grassland birds and pronghorn. More rain eastward feeds cross-timbers oak woodlands and bottomland and upland forests with white-tailed deer and forest birds. Rivers and reservoirs form riparian, wetland, and aquatic corridors for migration, breeding, and dispersal.

Animals

Wildlife

Oklahoma sits at a crossroads where Great Plains short‑grass and mixed‑grass prairies meet Cross Timbers oak woodlands, tallgrass prairie, and the Ozark/Ouachita uplands. Moisture rises from west to east, and rivers like the Arkansas, Canadian, Cimarron, and Red create varied habitats. Panhandle prairies and playa wetlands, sandhills and riparian cottonwood forests, the granite Wichita Mountains, and forested hills with clear streams are found. The west has prairie big game and grassland birds; the east has deer and woodland species, and Oklahoma is rich in freshwater fish and migratory birds.

Wildlife Viewing

Oklahoma offers varied wildlife viewing across prairie, cross-timbers woodlands, wetlands, and forests. Shortgrass and mixed-grass prairies host pronghorn, prairie chickens, and raptors. Riparian corridors and reservoirs draw migrating waterfowl and wintering eagles. Eastern Ouachitas and Ozarks hold white-tailed deer, black bear, and many songbirds. National Wildlife Refuges, state parks, wildlife management areas, and lakes support strong birding.

Best Seasons

Spring (Mar-May)

Peak migration and breeding activity: warblers, shorebirds, and waterfowl move through wetlands and reservoirs; prairie grouse display at dawn; wildflowers bring pollinators; amphibians call after rains. Great time for birding at refuges and for prairie drives in the west.

Summer (Jun-Aug)

Early mornings and evenings are best. Look for nesting/feeding behavior in herons and egrets, butterflies and dragonflies around wetlands, and night sounds (frogs, insects) along riparian trails. Bison and elk viewing remains strong at protected areas; lake country offers waterbird photography.

Fall (Sep-Nov)

A second major migration pulse: hawk and falcon movement increases, sandpipers and ducks gather, and rut activity begins for deer. Cooler temps make longer hikes comfortable in eastern forests; prairie sunsets plus raptors over open country are a highlight.

Winter (Dec-Feb)

Best season for bald eagles and large concentrations of waterfowl on rivers, lakes, and refuges. Visibility improves after leaf-drop in the east for deer and forest birds. Ideal for crisp photography days and scenic wildlife drives.

Top Wildlife Experiences

  • Dawn prairie-grouse viewing: visit Lesser Prairie-Chicken country in Oklahoma's northwest/panhandle prairies and arrange a local lek-viewing opportunity where permitted (best in spring, at first light).
  • Bison-and-prairie wildlife drive at Wichita Mountains Wildlife Refuge (near Lawton): scan open grasslands for bison, elk, prairie dogs, and raptors; add short hikes like Mount Scott area overlooks for wide-angle wildlife photography (year-round; sunrise/sunset best).
  • Winter bald eagle loop at Lake Tenkiller and the Illinois River corridor (near Tahlequah): watch eagles perched in shoreline trees and hunting over open water, especially after cold fronts (Dec-Feb).
  • Waterfowl and shorebird day at Salt Plains National Wildlife Refuge (near Jet): bird the flats and pools for migrating shorebirds and large waterbird numbers; pair with sunset photography on the wide-open landscape (spring/fall; check conditions).
  • Black bear and forest-wildlife watching in the Ouachitas: explore the Talimena Scenic Drive area and nearby trails for chance sightings and sign, plus excellent songbird and raptor viewing along ridgelines (best fall for comfortable hikes; bears more active spring-fall).
  • Wetland birding and photography at Sequoyah National Wildlife Refuge (near Vian): drive the refuge roads and use pullouts/short walks to view herons, egrets, ducks, geese, and winter eagles (strong fall-winter; good spring migration).
  • Prairie night-sky + nocturnal wildlife listening walk: choose a state park or refuge with open habitat (e.g., western prairie parks/refuges) for owls, coyotes, frog choruses, and night insects-bring a red light and stay on established areas (late spring-summer nights).

Wildlife Watching Types

Birding hotspots (migration, waterfowl, warblers, grassland birds) Bald eagle viewing (winter concentrations on lakes/rivers) Prairie wildlife drives (bison, elk, pronghorn in the west; raptors statewide) Wetland and shorebird watching (refuges, mudflats, reservoir edges) Big-game viewing (white-tailed deer statewide; black bear in parts of southeast) Raptor watching (hawks, falcons; wintering and migratory movements) Butterfly/dragonfly watching (late spring through summer near wetlands and wildflower-rich prairies) Nocturnal wildlife listening and stargazing pairings (owls, coyotes, frogs)

Guided Options

  • U.S. Fish & Wildlife Service (USFWS) programs at National Wildlife Refuges: check event calendars for guided bird walks, photo-friendly auto-tour days, and seasonal interpretive programs (e.g., Sequoyah NWR, Salt Plains NWR).
  • Oklahoma Department of Wildlife Conservation (ODWC) resources: wildlife-watching guidance, WMA access info, and seasonal recommendations; some areas host educational events and viewing weekends.
  • Wichita Mountains Wildlife Refuge interpretive programs: ranger-led talks/walks and visitor center information that can help visitors plan ethical bison/elk viewing routes and timing.
  • State park naturalist programs (varies by park/season): evening programs, guided nature walks, and birding outings-especially in larger parks in eastern hills and lake regions.
  • Local birding organizations and Audubon chapters: often run scheduled field trips during spring and fall migration (good for visitors who want up-to-date hotspot intel and ID help).
  • Outfitter-led nature photography or birding trips (regional operators): private or small-group outings around major lakes/refuges for sunrise waterfowl, eagle photography in winter, and spring songbird walks (availability varies; book ahead in peak seasons).
Habitats

Ecosystems

Oklahoma lies where the Great Plains meet eastern woodlands and southern forests. It ranges from semi-arid shortgrass and mixed-grass prairies in the west, through Cross Timbers oak woodlands, to wetter deciduous and pine-oak forests in the east. Rivers (Canadian, Cimarron, Arkansas, Red) and reservoirs create riparian corridors, floodplains, and wetlands that support migratory birds, grassland species, and forest wildlife.

Biomes

Temperate Grassland

Prairie-dominated landscapes ranging from shortgrass and mixed-grass prairie in the west to tallgrass prairie remnants (notably in the Flint Hills/Osage Hills) and mixed prairie/old-field grasslands across much of the state.

Widespread; dominant in western Oklahoma and common across central areas, with tallgrass strongest in the northeast/Flint Hills region.

Temperate Forest

Broadleaf and mixed forests, including oak-hickory forests in the east/northeast (Ozark margin) and pine-oak/shortleaf pine systems in the southeast (Ouachita and South Central Plains). Cross Timbers forms a forest-grassland mosaic in central Oklahoma.

Concentrated in eastern and southeastern Oklahoma; patchy woodland/forest mosaics extend into central Oklahoma (Cross Timbers).

Freshwater

Large river networks, oxbows, and a high density of reservoirs/impoundments support fish, mussels, riparian wildlife, and waterfowl migration stopovers.

Statewide along major basins (Arkansas, Red, Canadian, Cimarron) and hundreds of lakes/reservoirs.

Wetland

Floodplain forests, sloughs, marshes, wet meadows, and managed wetlands occur along major rivers and lowlands, especially in the east and southeast; playa-like seasonal wetlands also occur locally in the west.

Patchy but important statewide; most extensive along large river floodplains and in wetter eastern/southeastern lowlands.

Habitats

Grassland

Mixed-grass and shortgrass prairies dominate the west; native grasslands support prairie birds, pronghorn (west), and grassland raptors.

Prairie

Tallgrass prairie remnants and large intact tracts occur in the Flint Hills/Osage Hills region; mixed prairie occurs broadly in the central/western portions.

Steppe

Drier mixed-grass/shortgrass steppe-like conditions in far western Oklahoma (High Plains and adjacent tablelands), with sparse tree cover and strong wind/temperature extremes.

Shrubland

Sand sagebrush and other shrub-dominated communities occur in sandy or drought-prone western sites (including parts of the Cimarron/Canadian basins).

Woodland

Cross Timbers oak woodland (post oak/blackjack oak) forms a classic mosaic of woodland and grassland across central Oklahoma, influencing fire regimes and habitat connectivity.

Deciduous Forest

Oak-hickory forests and bottomland hardwoods in eastern Oklahoma (including the Ozark edge) and along riparian corridors statewide; important for deer, turkey, and songbirds.

Coniferous Forest

Shortleaf pine and pine-oak communities in southeastern Oklahoma (Ouachita Mountains and adjacent South Central Plains), often managed for timber and fire-dependent structure.

Forest

Mixed upland and bottomland forests increase eastward; forested ridges and valleys in the Ouachitas and eastern uplands provide diverse microhabitats.

River/Stream

Major river corridors (Arkansas, Red, Canadian, Cimarron) with sandbars, cutbanks, and wooded floodplains; key migration and dispersal routes for wildlife.

Lake

Numerous reservoirs (e.g., Eufaula, Texoma, Tenkiller, Grand) support fisheries, waterfowl, and shoreline wetland complexes.

Pond

Farm ponds and small impoundments are common statewide, providing amphibian breeding habitat and supplemental water for wildlife and livestock.

Wetland

Seasonally flooded bottoms, wet meadows, and managed marsh units (especially along major rivers and in southeastern lowlands) support waterfowl and wading birds.

Swamp

Localized forested wetlands and sloughs in eastern/southeastern floodplains, often dominated by water-tolerant hardwoods.

Marsh

Emergent marshes along reservoir margins and river backwaters; important for rails, bitterns, amphibians, and nutrient filtration.

Cave

Karst and cave habitats occur in parts of northeastern Oklahoma (Ozark margin) and some limestone areas, supporting bats and specialized invertebrates.

Cliff/Rocky Outcrop

Rock bluffs and escarpments occur in eastern uplands and river valleys, providing nesting/roosting sites for raptors and cliff-dwelling species.

Mountain

The Ouachita Mountains in the southeast and the Wichita and Arbuckle Mountains in the south-central region create rugged uplands with distinct plant communities and microclimates.

Agricultural/Farmland

Extensive cropland and pastureland (wheat, sorghum, hay, cattle) create a patchwork with remnant prairies, shelterbelts, and riparian buffers.

Urban

Urban habitats around the Oklahoma City and Tulsa metros and smaller cities, with parks, reservoirs, and riparian greenways that provide secondary habitat.

Suburban

Expanding suburban matrices around major metros, often retaining fragmented woodlands (Cross Timbers/eastern forests) and small wetlands/ponds.

Protection

Conservation

Primary Threats

  • Native tallgrass and mixed-grass prairie have been reduced and fragmented by cropland conversion, improved pastures, and parcelization; remaining grasslands are often broken by roads, fences, and energy infrastructure, reducing habitat quality for prairie-chickens, grassland songbirds, and pronghorn.
  • Row-crop expansion (often enabled by irrigation in the west) and pasture intensification replace diverse native plant communities with monocultures, simplify vegetation structure needed for ground-nesting birds, and increase sediment/nutrient runoff into creeks feeding major reservoirs and rivers.
  • Fire suppression and altered grazing regimes drive woody encroachment (e.g., eastern redcedar) into prairies and savannas, converting open grassland into shrub/woodland and degrading habitat for prairie specialists; channelization, reservoirs, and altered flow regimes modify riverine habitats for mussels and fishes.
  • More frequent/intense drought and heat stress reduce forage and water availability in western rangelands and can depress recruitment of grassland birds; heavier downpours increase flash flooding and erosion in watersheds, stressing aquatic species and increasing turbidity/sedimentation.
  • Nutrients, pesticides, and sediments from agriculture and urban stormwater degrade streams and reservoirs; localized contamination risks include legacy and active oil/gas activities and abandoned sites that can contribute brines/hydrocarbons to soils and waterways if not properly managed.
  • Eastern redcedar encroachment is a landscape-scale issue; invasive grasses (e.g., Old World bluestems in some areas) and feral hogs degrade habitat and water quality. Aquatic invasives (e.g., zebra mussels in some reservoirs) can disrupt food webs and infrastructure and complicate native mussel conservation.
  • White-nose syndrome threatens Oklahoma's cave- and bridge-roosting bats; chronic wasting disease risk requires continued surveillance and carcass movement controls to protect deer/elk management and hunting economies.
  • Road networks, expanding wind/solar development, transmission lines, and fencing can fragment habitats and create collision risks (birds/bats) and movement barriers; river crossings and small dams can impede fish passage and alter stream connectivity.
  • Historic and legacy mining impacts persist in parts of northeastern Oklahoma (e.g., lead/zinc mining districts), where contaminated sediments and floodplain soils can affect aquatic life and riparian food webs; remediation is ongoing in some areas.
  • Recreation pressure on lakes/rivers and off-road vehicle use in some areas can disturb nesting birds and accelerate erosion; cave visitation can disturb bat colonies, especially during sensitive seasons.
  • Conflicts include crop depredation and fencing issues with expanding deer/elk populations, feral hog damage, and occasional predator-livestock concerns; increasing urban/suburban interfaces can elevate vehicle collisions and nuisance wildlife issues.
Fun Facts

Did You Know?

Oklahoma has "seabirds" nesting far from any ocean: interior least terns regularly nest on the salt flats at Great Salt Plains NWR-an inland, high-glare, salty environment that looks nothing like a beach.

The state bird, the scissor-tailed flycatcher, is built for aerial stunts: its tail streamers can be as long as (or longer than) its body, and it's famous for aggressively mobbing larger birds like hawks during nesting season.

In one day's drive you can cross ecosystems that support pronghorn on the western shortgrass prairie and black bears in the forested Ouachita region of southeastern Oklahoma-two iconic species that most people associate with completely different parts of North America.

Wichita Mountains Wildlife Refuge is "prairie meets granite": collared lizards-bright green/blue, rock-loving reptiles-live on sun-baked granite boulder slopes rising out of the surrounding plains.

Some Oklahoma shorebirds choose salt over sand: snowy plovers also nest on the Great Salt Plains, using open, salty flats that can resemble a lunar landscape more than typical bird habitat.

The Tallgrass Prairie Preserve (Osage County) protects about 39,650 acres-widely cited as the largest protected remnant of tallgrass prairie in the world-and it's managed with a free-ranging bison herd.

The alligator snapping turtle-North America's largest freshwater turtle-lives in southeastern Oklahoma (Red River drainage). Adults can exceed 100 lb, with exceptional individuals much heavier.

American bison are the largest native land mammal in Oklahoma; mature bulls commonly reach 1,500-2,000+ lb. You can see conservation herds at places like the Wichita Mountains Wildlife Refuge and the Tallgrass Prairie Preserve.

The Great Salt Plains National Wildlife Refuge has a huge inland salt flat—about 11,000 acres when dry—one of the largest in the interior United States. This rare habitat affects which birds can nest there.

The bullsnake (a subspecies of gopher snake) is among the longest snakes found in Oklahoma; verified individuals can approach ~8 feet, making it a "biggest-by-length" contender in the state's snake lineup.

Oklahoma’s humid subtropical climate and different geographic zones allow it to have a great variety of wildlife. Because of this, there are wild creatures that range from the most common to the rarest, from the familiar to the strange, from the beautiful to the homely. Here are some of Oklahoma’s wild animals and where they can be found:

The Official Animals of Oklahoma

Official State Mammal: American Bison

The American bison, was nearly hunted into extinction in the 19th century, so this is an ironic choice.

Official State Game Animal: White-tailed Deer

This deer, which is so numerous that it’s considered a pest in some places, is a favorite of hunters.

Official State Bird: Scissor-tailed Flycatcher

This pretty, insectivorous bird is identified by its very long, forked tail.

Official State Raptor: Red-tailed Hawk

This bird is one of the most common hawks in North America and can be found in many habitats, from farms and forests to cities.

Official State Game Bird: Turkey

The wild turkey was once in the running to be the national bird of the United States. Like the white-tailed deer, it is a favorite of hunters.

Official State Flying Mammal: Mexican Free-tailed Bat

This fast-flying, high-flying little bat is one of the most common bats in the Americas. It can form colonies of tens of thousands of individuals.

Official State Reptile: Collared Lizard

This colorful lizard is named for the bands of black around its neck. Males are rainbow-colored.

Official State Amphibian: Bullfrog

The bullfrog is common in Oklahoma’s lakes, ponds, and swamps.

Official State Butterfly: Black Swallowtail

The males of this large, beautiful butterfly are mostly velvety black with blue, red, and yellow spots on the hind wings. The wings of the females are bluer.

Official State Insect: Honeybee

Known for its industriousness, this insect is a crucial pollinator of food crops.

Official State Fish: White Bass

A freshwater fishnative to North America, the white bass is a popular game fish found in lakes and rivers. This fish has a silver-white body with dark vertical stripes. It eats smaller fish, insects, and crustaceans.

Official State Amphibian: Bullfrog

The bullfrog is a semi-aquatic frog, primarily know for the loud call sounds it makes. They are the largest frogs that naturally exist in North America

Where To Find The Top Wild Animals in Oklahoma

Though few animals are actually confined to Oklahoma’s wildlife and nature areas, they are the best places to see the larger creatures such as bison. Some of these places also allow hunting and fishing.

Visitors to these and other areas in the state can also find:

Insects

Insects are of course the most common type of animal in Oklahoma as they are the most common animals just about everywhere. Besides its many varieties of butterflies and moths, the state is home to honeybees, which are the state insect, wasps, hornets, beetles, and true bugs. It also has cockroaches, cicadas and cicada killers, grasshoppers, katydids, dragon and damselflies, weevils, ants, termites, and fireflies.

Other Arthropods

Other arthropods include spiders, wolf spiders, black widows, brown recluse spiders, orb weavers, and cat-faced spiders, tarantulas, ticks, millipedes and centipedes, and the striped centroides scorpion. There are also crayfish, including the Delaware County Cave crayfish. This is one of the rarest crayfish as it’s only found in three caves in the aforementioned county.

Reptiles and Amphibians

Reptiles of Oklahoma include the common alligator. Alligators are actually native to Oklahoma but uncommon. They are mostly found in the Little and Red Rivers and their tributaries down in the state’s southeastern corner.

Other reptiles found in Oklahoma are skinks and other lizards, including the colorful collared lizard and the Texas horned lizard, a creature with a strange habit of spurting blood out of its eyes when it’s upset. The western slender glass lizard is legless and looks just like a snake but is not. You can tell because it has eyelids and earholes.

Turtles include the three-toed box turtle, the stinkpot, and the snapping turtle. Among the great variety of snakes are the speckled kingsnake, the western worm snake, the rough green snake, coachwhips, racers, milk snakes, garter snakes, and bull snakes. Oklahoma also has a good number of venomous snakes including the copperhead, the cottonmouth, and several species of rattlesnake.

Because they require lots of moisture, amphibians are mostly found in eastern Oklahoma. One of the rarest and most unusual is the three-toed amphiuma, which looks like an eel but is actually a 30-inch long nocturnal salamander. It appears legless at first but has legs that are so tiny that it can’t support the animal’s weight. Because of that, amphiuma is aquatic. Another strange amphibian is the siren, another eel-like nocturnal creature that spends the day in the muddy bottoms of torpid streams. More familiar amphibians include species of salamanders, toads, and frogs including the Kiamichi slimy salamander, the bird-voiced tree frog, and the Cajun chorus frog.

Fish

Oklahoma is a landlocked state, but it is known for the bounty found in its rivers and lakes. There are more than 177 types of fish in Oklahoma, and they include bass, shiners, chubs, gars, sturgeons, shads, minnows, buffalos, darters, madtoms, catfish, sunfish, perch, and trout. Both the rainbow trout and the brown trout were introduced and aren’t native to the state.

Bats

Examples of these mostly nocturnal animals, the only mammals capable of true flight, are the little brown bat, the hoary bat, the western and eastern pipistrelle, the Seminole bat, and the Yuma myotis.

Rodents

Some of the most common creatures in Oklahoma are rodents. Besides the ubiquitous house mouse, mice include the hispid pocket mouse, the plains pocket mouse, and the meadow jumping mouse. Other rodents are kangaroo rats, woodrats, brown rats, and black rats. Voles, squirrels, chipmunks, ground squirrels, prairie dogs, and groundhogs call Oklahoma home. Larger rodents are the North American beaver and the North American porcupine as well as gophers and nutria, and introduced large rodent that has become invasive in some areas. The marsupial Virginia opossum is also found in Oklahoma.

Small Mammals

Small mammals found in the refuge, parks, farms, pastures, and sometimes backyards of Oklahoma are rabbits including the eastern cottontail and the swamp rabbit. Others are armadillos, skunks, raccoons, weasels and ferrets, the American mink, and the American badger. The ringtail cat, a nocturnal cousin of the raccoon, can also be spotted in the canyons and other rocky areas of Oklahoma. There are several species of shrews and moles.

Large Mammals

Among the large mammals that live in Oklahoma are the American bison and the plains bison. Deer are the white-tailed deer, the mule deer, and the elk. Pronghorn antelope are found in the prairies of the panhandle, and hunters seek out the wild boar.

Birds

Many birds come to Oklahoma to spend the winter or to raise a family before they move on. Other birds are permanent residents. Many of these birds are waterfowl and include swans, geese, ducks, cranes, stilts, avocets, gallinules, pelicans, storks, and coots. Though sandpipers, curlews, godwits, and knots are considered shorebirds, the ranges of these birds include Oklahoma. Even seabirds such as gulls, terns, and skuas overwinter in Oklahoma. They can be found near lakes and rivers as well as trash dumps.

Songbirds of Oklahoma include the blue and rose-breasted grosbeak, buntings, cardinals, tanagers, and a cardinal relative called the pyrrhuloxia, whose female is blue instead of red. Other birds are warblers, wrens, starlings, orioles, blackbirds, crows, ravens, grackles, and meadowlarks, sparrows and juncos, finch, and thrushes, including the robin and all three species of bluebird. There are also waxwings, thrashers, nuthatches, hummingbirds and woodpeckers, swallows, jays, chickadees, shrikes, vireos, and flycatchers. Birds of prey include ospreys, eagles, kites, falcons, hawks, vultures, and owls.

Predators

Oklahoma does have its share of predators. Besides the birds of prey mentioned, there are the common alligator and other reptiles. The bobcat is the only largish cat left in Oklahoma after the extirpation of the cougar, as the coyote and the gray, red, and swift foxes have taken the place of the gray and Great Plains wolf. The former has been extirpated from Oklahoma while the latter is extinct. The American black bear is Oklahoma’s other large predator. Smaller predators include bats, amphibians, certain fish, and shrews. The armadillo preys mostly on insects but will eat other small animals if it must.

Zoos in Oklahoma

Those who don’t want to trek into the wilderness to see Oklahoma’s wild creatures can always visit its zoos, with its displays of beasts native and exotic. They include the Oklahoma City Zoo and Botanical Garden, the Tulsa Zoo, the Lost Creek Safari in Stillwater, the Greater Wynnewood Exotic Animal Park, and the Pawsitively Wild Animal Encounters and Education Center. Aquariums includethe Blue Zoo, the Oklahoma Aquarium, and the Medicine Park Aquarium and Natural Sciences Center

Wild Animals in Oklahoma

Other wild animals to be found in Oklahoma are the eastern or common mole, a strange-looking little beast with naked outsized hands made for digging, tiny eyes, and a long, twitching snout. The southern flying squirrel doesn’t fly but glides from tree to tree due to a membrane attached to its four legs. The little stinkpot turtle gets its name because it has glands that release a nasty odor to put off predators.

The citrine forktail is a delicately beautiful damselfly. There’s a population of this insect in the Azores that reproduces through parthenogenesis. They’re the only members of the Odonata order that does this. The loggerhead shrike, another of Oklahoma’s predatory birds, is fond of killing prey by twisting its neck around then skewering it on barbed wire or thorns.

While the copperhead is listed below among the most dangerous animals, we could have also listed the prairie rattlesnake, the Western diamondback rattlesnake, the pygmy rattlesnake, or the Western cottonmouth (water moccasin).

The Most Dangerous Animals In Oklahoma Today

Most of the truly dangerous animals, such as the grizzly bear, were extirpated from Oklahoma a while ago, so there are few animals that are really dangerous to humans. They are:

  • Black bears. The American black bear has been known to attack humans, especially if it’s used to being fed by them. Mother bears are fiercely protective, and it’s a bad idea to come in between a mother bear and her cub.
  • Copperhead snake. The problem with the copperhead is that it doesn’t warn you away with a rattle or a gaping mouth like the cottonmouth. It freezes, and since it has the same coloration as fallen leaves, it is too easy to step on it and get bitten.
  • American bison. It’s best to watch this magnificent beast at a safe distance. Though not nearly as vicious as an African buffalo, it can charge for what seems like no reason, especially during the summer rut.
  • Striped centroides scorpion. This is a little scorpion, so it is easy to overlook. It likes to hang out in cords of lumber and sometimes makes its way into the house, where people come into contact with it accidentally. Its venom is powerful and a person who is stung should seek a doctor’s attention.
  • Mountain lion. A large, tan-colored cat species, the mountain lion (AKA puma, cougar, panther) lives in more geogrphies than any other Western Hemisphere mammal besides humans.
  • Black widow sppider. Their reputations are fierce, but in reality, black widow spiders — aka Latrodectus — are calm, loner pacifists that only unleash venomous bites when they’ve exhausted all other defensive options.

Endangered Animals In Oklahoma

A few of the endangered animals in Oklahoma are:

  • Oklahoma cave crayfish. This crustacean, which is nearly colorless thanks to its cave habitat, is critically endangered. It presumably feed on roots, stems, and leaf fragments found within its range.
  • Arkansas River shiner. Once abundant from Arkansas to Texas, this bright little fish is now only found in parts of the Canadian River, which passes through New Mexico, Texas, and Oklahoma. It is classified as vulnerable.
  • Ozark big-eared bat. This bat with its enormous ears that connect to its forehead is now only found in a few caves in Oklahoma, Arkansas, and Missouri.
  • Texas kangaroo rat. This little rodent is considered vulnerable, as its population is decreasing due to habitat destruction.
  • Neosho mucket. Hstorically found throughout the Verdigris, Caney, Neosho, Spring, and Illinois rivers in Oklahoma, this mussell now resides mostly in the Illinois River.
  • American burying beetle. Known to occur in at least 29 counties in the state, mostly in eastern areas with open, oak-hickory forests with native grass cover. It gets its name from its practice of eating only carcasses and burying them.

Native Plants in Oklahoma

Oklahoma’s wildflower is the Indian Blanket, a short-lived flowering plant that produces daisy-like inflorescences of bright red, yellow, and orange coloration! Almost a quarter of the state is covered in forests that serve as a natural habitat for various trees, shrubs, and ferns. Some native plants in Oklahoma are the swamp rose mallow, willow oak, American smoke tree, American lotus, Jack-in-the-pulpit, Meadow Flower, Prairie Shoestring, Blue Wild indigo, and Wild Berganot. Use the link above for full descriptions and pictures of each of these wildflowers.

Rarest Animals

For rare and exotic species, there are a number of sanctuaries, like the Safari Sanctuary in Broken Arrow, but not all are open to the public and most are run by private foundations. For example, the Endangered Ark Foundation is dedicated to ensuring the future of Asian elephants in North America, providing a retirement ranch for circus elephants, and educating the public about this endangered species.

Largest Animals

The five largest animals in Oklahoma are described here. They include the American bison as the largest mammal, the Alligator Gar as the largest fish, the Bald Eagles as the largest bird, the Cottonmouth as the largest snake, and the Iron Worm as the largest insect. An amazing group!
