White-Tailed Deer
In southern Illinois, these iconic deer species are often seen in both urban and rural landscapes in Illinois. These deer family members are grazers and usually eat twigs, leaves, grass, and vegetables.
The white-tailed deer is named after their physical feature, which includes its white tail. They have a keen sense and impressive agility, which helps them to survive in the wild.

This important species went extinct once due to overhunting and habitat loss in Illinois. But, wildlife conservationists are focused on increasing and protecting the gray wolf population.
The gray wolf has thick gray fur and looks like a German Shepherd dog. These amazing wild animals are highly adaptable and inhabit diverse natural habitats, like dense forests, open grasslands, tundra, taiga, and mountains.
They are the apex predators and play a crucial role in maintaining the balance of the ecosystem. Their absence from nature can cause an increase in the population of grazers (animals that are herbivores).
Red Foxes
Red foxes are one of the interesting Illinois animals. They are often seen stealthily navigating in the forests and grasslands in search of their prey. These foxes are usually active from dawn to dusk.
How to recognize the red fox if spotted?
The upper side of their fur is mostly reddish brown, with white underparts and a bushy tail. Additionally, you might spot them on the campground. But there is a lesser chance of it.

River Otters
These charismatic aquatic mammals are popular for their playful behavior and excellent swimming skills. With their streamlined bodies and webbed feet, they are perfectly adapted to aquatic life.

Despite facing habitat loss and pollution threats, conservation efforts have helped some populations recover. Presently the IUCN Red List of Threatened Species listed otters as “Least Concern.”
Eastern Gray Squirrel
Eastern grey squirrels are expert climbers, easily scampering up trees to search for nuts, acorns, and seeds. These agile and curious rodents have bushy tails and gray fur. Their fur color ranges from dark brown to black, with white underparts.
Squirrels are highly adaptable and thrive in diverse habitats, from urban parks and suburban backyards to deciduous forests. Eastern gray squirrels are crucial for the forest ecosystem, as they help in seed dispersal.
Black Bears
It is the only species of bear native to Illinois. Despite their name, their fur can range from black to dark brown. Although sightings are rare, black bears have been observed in the southern parts of the state.
Black Bears are omnivorous and feed on fruits, nuts, insects, and occasionally small mammals (depending on the season). Their natural habitats are urban and suburban areas. They are excellent climbers and swimmers, which helps them in foraging for food and escaping from potential threats.
Brown Rat
It is also called the Norway rat and is one of the most interesting animals in Illinois. These invasive species are inhabitants of many parts of Europe and North America. Their reproductive capabilities have contributed to their widespread distribution.
These rats have a distinctive appearance with a stout body, short ears, and a scaly tail. Their fur color can vary from brown to gray, and they have a lighter-colored belly.
Brown rats are highly adaptable and thrive in a variety of habitats, including urban areas, farmlands, and natural environments. They are opportunistic feeders, consuming a wide range of foods, including grains, fruits, insects, and scraps left by humans.
Due to their scavenging behavior and ability to reproduce rapidly, brown rats have become pests in many urban areas, which cause damage to property and pose health risks as they carries various diseases.
Raccoons
These medium-sized mammals are native to North America and can be found in a variety of habitats, including forests, wetlands, and urban areas. Their adaptability helped them to thrive in both urban and suburban areas.
Raccoons are omnivores, meaning they have a diverse diet that includes fruits, nuts, insects, and small mammals. They have a strong sense of smell and sharp claws that help them to search for food. During the colder months, raccoons do not truly hibernate.
Despite their adaptability and abundance, raccoons face challenges from human interactions, such as habitat loss, vehicle collisions, and conflicts with pet animals.
Thirteen-lined ground squirrel
The name of the thirteen-lined group squirrel derives from the thirteen stripes that adorn their backs. Thirteen-lined ground squirrels primarily inhabit grasslands, open fields, and prairies. In their natural habitats, they construct complex burrow systems for shelter and hibernation.
How do they survive in the wild?
These burrows serve as crucial protection against predators and extreme weather conditions. They are important prey for many predators, such as birds and snakes.
Do these squirrels hibernate?
During the winter months, they undergo a period of hibernation to conserve energy. Their quick movements and agility make them skilled at escaping potential threats.
Bobcats
Bobcats are one of the most interesting animals in Illinois. When it comes to their appearance, these large cats have tufted ears and stubby tails. One of the interesting facts about these wild cats is they change their fur color seasonally.
Their fur remains reddish brown in summer, and it turns grayish brown in winter. They do this for better camouflage and their survival in the wild.
Bobcats are skilled hunters, preying on rabbits, rodents, and birds, playing a crucial role in maintaining ecological balance by controlling rodent populations.
The occasional sightings of the bobcats near human settlements are evidence that they have the ability to coexist. However, these wild cats are reclusive in nature.
