Idaho, in the United States, has forests, mountains, marshes, farmlands, and rivers in its landscape. So, it’s no surprise that the state is home to a diverse wildlife population. There are more than 300 animal species living in Idaho forests. In addition, there are around 100 species of fish living in the Idaho rivers and streams.
Just a few of the most well-known wild animals living in Idaho include grizzly bears, bighorn sheep, wolverines, wildcats, Cooper’s hawks, native white sturgeons, and prairie rattlesnakes.
The Official Animal of Idaho
With its large collection of wildlife, Idaho has more than one animal representing the Gem State.
Official State Bird of Idaho: Mountain Bluebird
The mountain bluebird (Sialia currucoides) was made the official state bird of Idaho back in 1931. This bird can’t help but stand out with a layer of sky-blue feathers on its back and light blue feathers on its breast. These birds are able to endure cold (but not freezing) temperatures. Many of them live in tree hollows in forests located in the Idaho mountains. If they can’t find a tree hollow to serve as their nest, these birds can live inside holes located in cliffs or hillsides.
Official Fish of Idaho: Cutthroat Trout
In 1990, the cutthroat trout (Oncorhynchus clarki) became the official state fish of Idaho. These notable fish are named for the slash of reddish/orange scales beneath their mouth. There are two species of cutthroat trout living in Idaho. One is the Westslope cutthroat trout and the other is the Yellowstone cutthroat. They live in many of the state’s clean, cold streams.
Official Domestic Mammal of Idaho: Appaloosa Horse
The Appaloosa horse became the state domestic mammal in 1975. These horses are known for their patterns of brown, white, silver, and black spots. They were first seen hundreds of years ago in Idaho near the Palouse River. At that time, they were known as Palouse horses. But, over time, the word Palouse slowly transformed into Appaloosa.
Official State Raptor of Idaho: Peregrine Falcon
The Peregrine falcon (Falco peregrinus) became the state raptor of Idaho in 2004. This majestic bird can be seen soaring above Idaho fields and forests. It claims the title as one of the fastest birds in the world. They live along rivers, in the mountains and sometimes can be seen nesting on buildings in urban areas. Their conservation status is Least Concern.
Where to Find the Top Wild Animals in Idaho

The desert horned lizard and the Great Basin collared lizard are other reptiles living in rocky areas on the prairie.

The Most Dangerous Animals in Idaho Today
Most states have some animals that could be considered dangerous. Idaho has a few of its own. Keep in mind that many animals have the potential to become dangerous if they feel threatened or if they feel their young are being threatened. Consider some of the most dangerous animals in Idaho.
- Grizzly bears are well-known predators and some of the most dangerous animals in this state. An adult grizzly bear can grow to a height of five to eight feet tall and weigh up to 800 pounds! They are incredibly strong mammals and have been known to turn aggressive especially when their cubs are being threatened. Fortunately, grizzly bear attacks on humans are rare. There have been only 18 reported deadly attacks of people by grizzly bears in and around Yellowstone Park over the last 130 years.
- The Great Basin rattlesnake is another dangerous animal in Idaho. This is a venomous snake that can be seen sunning itself on rocks and near roads. Adult Great Basin rattlesnakes can grow to be more than five feet long. These snakes have a rattle on their tail that serves as a signal to humans and animal predators to stay away. This snake would rather avoid conflict and go about the business of hunting shrews, pocket gophers and other common rodents. If a person is bitten, medical attention is necessary. However, death is the rarest outcome of a Great Basin rattlesnake bite. In fact, only one in 500 people die from the bite of a rattlesnake.
- Bison also make the list of dangerous animals in Idaho. This makes sense considering the sheer size of these mammals. Male bison can weigh around 2,000 pounds and grow to a height of six or seven feet. These animals can be territorial so a person wandering through their habitat is at risk for injury or death. These mammals are unpredictable and can charge at speeds of up to 35 mph. Though there have been many attacks resulting in injuries (to the human), there have been just two deaths in Yellowstone over the past 20 years.
- The gopher snake is another dangerous animal in Idaho. Though these are not venomous snakes like the Great Basin rattlesnake, their bite is known to be very painful. These snakes are classified as constrictors, so they squeeze prey including amphibians and rodents instead of biting them. Adult gopher snakes can grow to a length of three to four feet. They can sometimes be mistaken for rattlesnakes because they shake their tail in a similar way. They can also flatten their head in a strange way making their head appear triangular like a rattlesnake’s!
- Black widow spiders are also dangerous animals living in Idaho. Females are black with a bright red hourglass design on their abdomen. They are venomous spiders, but only cause death in the rarest circumstances. Normally, these spiders bite when a person mistakenly reaches into an area where the spider has made a web. The person may not even know the web is there. The spider bites to defend itself against predators. Approximately, 4 to 8 people die each year from this spider’s bite, but other health issues may be involved in those deaths. Medical attention is needed for a black widow’s bite because it can cause a person to become ill. Nausea, sweating, abdominal pain, headache and swelling of the bite area are all symptoms of a black widow bite.
Endangered Animals in Idaho
Endangered (or Vulnerable) animals in Idaho include:
- Northern Idaho ground squirrel – These squirrels have a population of approximately 1,000 mature individuals. They are experiencing loss of habitat due to expansion of farmland. Also, they must compete for food with other species of ground squirrel in their region.
- Kootenai River white sturgeon -The population of this native fish has been at risk since 1969. They are Endangered due to habitat loss. Through the decades dam and dike construction have caused the Kootenai River’s water level to drop. A lower water level affects the egg laying activities of this fish.
- Woodland caribou – This mammal has a conservation status of Vulnerable with a decreasing population. They are at risk due to changes in their mountain habitat. These changes include road construction and other land development that affects their natural migratory habits.
- Columbia River tiger beetle – This beetle is one of the rarest sights in Idaho and its population is unknown. Changing water levels in the Columbia River are responsible for the decline in its population. The water level changes that are occurring naturally affect the egg-laying habits of this beetle.
- Pinyon Jay – The estimated population of this bird is 500,000 to 999,999 mature individuals. However, biologists believe their population is decreasing. Loss of their habitat via deforestation is the reason these birds are Endangered.
Native Plants in Idaho
With syringa as the state flower of Idaho, the state has the right environment for different plants to grow. From shrubs to tall trees, The Gem State has a diverse array of flora to boast of. Native plants in Idaho have advantages that should be discovered.
