Iowa is a midwestern state famous for its corn and its yearly state fair. More than 85% of Iowa’s land is dedicated to agriculture. It borders Minnesota to the north, Wisconsin, and Illinois to the east, Missouri to the south, and Nebraska to the west. Its major rivers are the Mississippi, Big Sioux, and Missouri.
Although much of Iowa is flat farmland, it has some gently rolling hills. Iowa’s weather is continental, which means it gets harsh, cold winters and hot, humid summers. Thunderstorms and tornadoes are common events in Iowa.
Wild Animals in Iowa
Iowa has over 1,100 species of fish and wildlife. The state’s forested areas are home to many common forest animals, including white-tail deer, gray foxes, red foxes, coyotes and bobcats. Its native small mammals include opossums, otters, muskrats and the strange but adorable eastern mole.
Iowa has many lakes, rivers and streams. It is the only U.S. state completely bordered by two major rivers. Its river shorelines and lakes contain walleye, catfish and crappies. You will find river otters, turtles, bullfrogs, ospreys and swans. Iowa is home to several species of waterfowl, including blue-winged teals, mallards and cranes.
One of Iowa’s famous birds is the bobolink. This grassland prairie bird has striking black and white coloring. It is the only North American land bird with this plumage color, and it is one of the rarest birds in the country.
The state’s chief predators are bobcats, foxes and coyotes. Although mountain lions and moose have been seen in many parts of Iowa, they are not resident species. Biologists say they cross over from neighboring states.
Iowa’s native rodents include the eastern chipmunk, white-footed mouse, eastern squirrel and deer mouse. Its small mammals include the northern short-tailed shrew and the prairie vole. The state has nine bat species, including the little brown bat, which is one of the rarest bat species in the U.S.
The Official State Animal of Iowa
Iowa’s state animal is the American goldfinch (Spinus tristis). This lovely, bright yellow bird lives in open woods, orchards, suburban areas and marshy areas. The goldfinch nests in the late summer. It eats seeds and insects.
The state flower is the wild rose, and the state tree is the burr oak.
Where To Find the Top Wild Animals in Iowa
- Pike’s Peak State Park: Iowa’s first state park is a hiking and wildlife viewing area situated where the Mississippi and Wisconsin rivers meet. With spectacular river views, it is an ideal place to see fish, waterfowl and wildlife.
- Manawa Lake State Park: This park protects one of Iowa’s largest lakes. It is an excellent location to see pelicans, ducks and geese. The lake is also a favorite nesting site for bald eagles.
- Goose Lake Wildlife Area: This public park is a 1,300-acre public park that is an ideal location for birders and wildlife watchers. Among the birds you’ll see are sandhill cranes, wild turkeys and pheasants. You can also spot rodentss and small mammals, including muskrats, otters and opossums.
- Wapsi Flats Wildlife Area: Like other midwestern states, Iowa has focused on turning unused cropland into tallgrass prairie ecosystems. These ecosystems once covered most of the midwestern states. Now, only a small percentage remains. Wapsi Flats is a protected tallgrass prairie that is home to pheasants, eastern meadowlarks, bobolinks, northern harriers, grasshopper sparrows, partridges and wild turkeys.
The Most Dangerous Animals in Iowa
Although it has several native predators, these animals rarely attack humans.
Iowa has four species of venomous snake. Like the predators, they almost never attack humans.
- Timber rattlesnake: This large pit viper can reach 4 feet. The bite of the timber rattlesnake (Crotalus horridus) can be fatal if it’s left untreated. Timber rattlesnakes live in forests and marshy areas.
- Copperhead: The most common snake in the U.S., the copperhead (Agkistrodon contortrix) lives near streams and waterways. Its venom is not strong enough to kill an adult human, but it can cause intense pain.
- Eastern Massasauga Rattlesnake: This small, secretive snake has strong venom, but attacks are extremely rare. This snake is endangered.
- Prairie Rattlesnake: This snake (Crotalus viridis) has the largest range of any rattlesnake species in the U.S. Like the eastern massasauga, it is threatened by habitat loss.
Endangered Animals in Iowa
- Trumpeter Swan: These swans (Cygnus buccinator) were once common on Iowa lakes, but hunting and wetlands drainage wiped them out in 1883. In 1993, a program to reintroduce these swans began with just one nesting pair. There are now more than 100 nesting pairs of trumpeter swans in Iowa, and conservation efforts continue.
- Osprey: These water raptors (Pandion haliaetus) were once prevalent in Iowa, and they were of great cultural importance to the Omaha Nation. Ospreys were greatly harmed by pesticides in the 1950s. With the banning of certain pesticides, their numbers have improved. In recent years, conservation groups have reintroduced ospreys to Iowa’s waterways.
- Bald Eagle: Like ospreys, bald eagles suffered population losses from pesticides and illegal hunting. In 1995, the bald eagle was moved from endangered to threatened by the U.S. Fish and Wildlife Service. Today, the Mississippi River is home to the country’s highest concentration of bald eagle nests. The giant birds spend the winters hunting on the river.
- Eastern Massasauga Rattlesnake: This small snake lives in wet prairies, grasslands and wetlands. This rattlesnake (Sistrurus catenatus) is considered an indicator species because its health depends on the health of its primary ecosystem. The eastern massasauga is threatened by hunting and habitat loss.
Snakes in Iowa
Iowa is home to 28 different snake species. While the vast majority are non-venomous, four different snakes in Iowa have venom and deserve more attention.
