Montana is located north of Wyoming and situated just below the southern border of Canada. Much of the state of Montana is sparsely populated with people, but it has a diverse array of common native wildlife, including the rarest mammal in North America, the Black-footed Ferret. The state is home to over 100 other species of mammals as well, ranging in size from tiny rodents to huge predators. There are also some 440 different bird species, dozens of reptile and amphibian species, and plenty of wild game animals.

Montana has a few strange native species that may be surprising to find so far north, such as the Pygmy Rabbit, the Northern Scorpion, and the Rubber Boa. Its diversity is due in part to its unusual climate, which varies widely across the state due to its topography and proximity to the Pacific Ocean and Canada.

The Official State Animals of Montana

Because it is less populated than most other states, Montana is rich in wildlife and has several state animals.

The Official State Animal of Montana: Grizzly Bear

The Grizzly Bear (Ursus arctos horribilis) was given the honor of the official state animal and mammal in 1983. Over 55,000 students assisted in helping choose the state animal, and the Grizzly Bear was the winner out of 74 total mammals, including the Elk, which came in second.

The Official State Bird of Montana: Western Meadowlark

Montana’s state bird, adopted in 1931, is the Western Meadowlark. Though it may seem strange, these beautiful black, white and bright yellow birds are part of a subfamily of the blackbird. It is said that Meriweather Lewis was the first to describe this bird in writing, calling it similar to the eastern variety, but with a “richer and more varied” song.

The Official State Fish of Montana: Blackspotted Cutthroat Trout

The Blackspotted Cutthroat Trout (Oncorhynchus clarki) became the official state fish in 1977. This native Montana species is also sometimes called Yellowstone cutthroat trout or the west slope cutthroat trout. It was chosen because it requires a quality habitat to survive, just as the people of Montana desire a certain quality and way of life.

Where To Find The Top Wild Animals in Montana

All across Montana the climate changes due to its geography and topography. Because of this, at different locations, you may see birds, rodents, bison, ticks, elk, bighorn sheep, grizzly bear, lynx, moose, wolverines, coyotes, and wolves, or even beavers, badgers, porcupines, otters, mink, and bats. The best place to see them is by visiting the many parks and reserves.

The Most Dangerous Animals In Montana Today

The state of Montana is number one in animal-related deaths, according to the Center for Disease Control. Many of the animals that cause those deaths are not even predators!

  • Grizzly Bear – Though they are ferocious and can be deadly when they attack, bear attacks are among the rarest animal attacks in Montana.
  • Western Rattlesnake – Though they mostly prey on rodents and small mammals, their bite can be fatal to humans. Montana is home to 10 different snakes in total, but the western rattlesnake is the only venomous species in the state.
  • Deer – While it may seem strange for these mostly gentle creatures to make the list, more than one in 60 people are estimated to experience a deer-related car accident in Montana, the second highest such rate in the whole country.
  • Black Widow Spiders – These arachnids are responsible for about seven human deaths per year.

Endangered Animals In Montana

In the state of Montana, all of the following species are listed as threatened or endangered:

  • Black-footed Ferret – It probably comes as little surprise that the rarest mammal in the whole of North America is endangered.
  • Whooping Crane – These feathered predators are the tallest bird in North America, and migrate through Montana each year in smaller numbers.
  • Pallid Sturgeon – These large prehistoric fish, alive in the time of dinosaurs, are found in the Yellowstone and Missouri rivers, but their numbers are dwindling.
  • White Sturgeon – These fish are predators, once commonly found feeding on smaller fish and crustaceans in the Kootenai River Basin, their only known habitat in the state.
  • Grizzly Bear – Yes, even the state animal has a status of threatened. Human encroachment and habitat loss are the biggest threats to grizzlies.
