Your go-to spot to learn about nature


Why do opossums play dead?
Rolling over and playing dead might not seem like the best protective strategy, but for some animals it's just right.


Not your average plant: The bug-eating spoonleaf sundew
The spoonleaf sundew is a small carnivorous plant found in Will County. It lives in wet, acidic soil and supplements its diet by trapping and digesting insects with sticky, dew-like drops on its leaves. Though it looks delicate, this plant is a fierce predator and a great example of nature’s adaptability.


Duck diet: Why bread should be off the table
Feeding ducks bread may seem kind, but it’s harmful to their health. Bread lacks the nutrients ducks need and can lead to malnutrition, especially in ducklings. Instead of bread, offer healthy treats like corn, veggie scraps, or fruit — or better yet, let ducks find their own natural food to stay strong and thrive.


Prairie pride: Discover Illinois’ flower, tree and more
Illinois is nicknamed the Prairie State for its wide open landscapes and native plants. Keep an eye out for state symbols on your next visit: the violet, our state flower, blooms in many colors; milkweed supports monarchs as our wildflower; big bluestem, the tallest prairie grass, grows up to 8 feet tall; and the mighty white oak, our state tree, feeds wildlife and lives for centuries.


Meet the fast and fierce peregrine falcon
Peregrine falcons are rare but incredible birds found on six continents. Known as the fastest-diving bird, they can reach speeds up to 200 mph when hunting. They mainly eat other birds and can migrate up to 9,000 miles. Once nearly gone from the U.S. due to DDT, conservation efforts helped their recovery. Today, they’re thriving with a global population of 340,000.


Spin into summer with fun pinwheel craft
Make a fun, colorful pinwheel using paper, scissors, a tack, and a straw or pencil. Cut a square, mark the center, draw and cut lines from corners to the middle, fold in every other corner, and secure with a pin. Attach it to a straw or pencil, then watch it spin in the summer breeze!


Beyond ducks and geese: Cormorants rule the water too
The double-crested cormorant is a sleek, black water bird known for expert diving and fishing. Found across the U.S., it dives underwater to catch fish using webbed feet and sharp-hooked beaks. After fishing, they spread their wings to dry. You can spot them nesting in colonies at preserves like Lake Renwick. Once hunted, their population has since rebounded and is now stable.


Team of pollinators more than just bees, butterflies
Pollinators like bees and butterflies get the spotlight, but moths, beetles, and flies play vital roles too. Moths work the night shift, beetles have been pollinating since dino days, and flies help early blooms. Each has unique ways of spreading pollen, keeping nature thriving. So next time you see one, say “Thanks, pollinators!”


The secret underground life of moles
Moles are expert diggers that spend most of their lives underground. The eastern mole, common in Illinois, digs in soft, moist soil using strong, shovel-like front feet. They build shallow tunnels to hunt insects and deep tunnels for rest and raising young. Though rarely seen, moles help improve soil health by aerating and turning it over. Despite poor vision, their adaptations make them perfectly suited for life below ground.


Fishing is a peaceful way to spend the day
Fishing is full of surprises so pack light stay patient and enjoy nature. Be quiet near the shore to avoid scaring wildlife. Look for fish near weeds rocks or logs. If you get snagged stay calm and try different angles to free your hook and always clean up your line. Switch techniques if fish are not biting and remember the real win is spending time outside even if you do not catch a thing.


Robin's egg blue: Where does the color come from?
Robin’s egg blue comes from a pigment called biliverdin in the female’s blood, not from food. Many birds lay blue eggs, and egg color comes from two pigments: biliverdin (blue or green) and protoporphyrin (reddish-brown). Egg colors may offer camouflage or sun protection. Robins lay 3 to 5 eggs and incubate them for 12 to 14 days. Hatchlings fledge about two weeks after hatching and learn to fly shortly after.


This sweet native plant bears a familiar fruit
Hi I’m the wild strawberry also called Virginia or common strawberry found across Illinois in prairies meadows and woodlands I bloom in late spring with white flowers and grow sweet heart-shaped berries if conditions are right Loved by wildlife and pollinators I am one of the parent plants of the grocery store strawberry and part of the fragrant rose family.


Bright blue indigo buntings are a star of summer
The indigo bunting is a small, bright blue songbird seen in Illinois during breeding season. Only males are a vibrant blue, and their color comes from light scattering, not pigment. They sing sweet, repetitive songs and migrate up to 1,200 miles, using the stars to navigate. Females build low nests and raise the young. Though their population has declined, they remain common and can be found in shrubby areas across the eastern U.S.


Let's go fishing: A beginner's guide to casting a line
Fishing is a fun way to enjoy nature. Beginners need some fishing line, a rod and a reel with a bobber, small hooks, a weight, nail clippers and bait in your tackle box. Practice by learning to tie a Palomar knot and casting gently. Watch the bobber for bites, then lift the rod to hook the fish. Use wet hands to handle the fish and remove the hook carefully. Be patient and enjoy the outdoors.


Wild relatives: the desert-dwelling fennec fox
Fennec foxes, the world’s smallest foxes, live in the Sahara Desert and stay cool with large ears that release heat and with their fast-breathing rate. Weighing 2 to 3 pounds, they are nocturnal, hunting insects, rodents and plants at night. Their sandy-colored fur acts as camouflage, helping them hide from predators. Fennec foxes are monogamous and raise kits in burrows. Though often near others, they are solitary and rely on adaptations to thrive in harsh environments.


A frog's life: How these creatures transform
Frog and toad eggs in Will County are laid underwater in jelly-like clusters to stay moist. Each egg has a yolk that feeds the growing tadpole. Tadpoles hatch with a tiny tail, mouth and gills, later growing legs and switching from algae to meat as they become froglets. The numbers of eggs laid and the time it takes to grow into adults depends on the frog’s species.


These endangered herons are creatures of the night
The black-crowned night heron is a short, stocky, mostly nocturnal wetland bird. Once common in Illinois, it’s now endangered in the state due to habitat loss. These herons hunt at night, except during breeding season where they hunt during the say. They breed in colonies and care for their young together. Though rare locally, they live on every continent except Antarctica and Australia. A large colony now lives at Chicago’s Lincoln Park Zoo, helping scientists learn how to p


Spring sightings: Turtles return at Isle a la Cache
As spring commences, turtles begin to emerge from winter brumation. Isle a la Cache lagoon is a great place to spot species like painted turtles, snapping turtles, red-eared sliders and map turtles. Walk quietly and use binoculars to see them basking in the sun. Watch for nesting turtles crossing roads in May and June during breeding season. Rare Blanding’s turtles, with bright yellow necks, can also be seen at Isle a la Cache Museum. It's always a good day when you see a tur


Get to know the chubby-cheeked chipmunk
Eastern chipmunks are small ground squirrels found in eastern North America’s forests. Active during the day, they don’t fully hibernate but rest in burrows and emerge to forage on milder winter days. They use their cheek pouches to carry food and store it in underground caches. Chipmunks eat fruits, seeds, insects and more. They communicate with high-pitched calls and prefer to stay near their burrows to avoid predators.


Can you spot the spots? All about the spotted turtle
Spotted turtles are tiny, hand-sized turtles with yellow spots on their top shell. They live in the eastern U.S.’s wetlands, including parts of Illinois. They eat insects, frogs and plants, and often bring their food into water to eat. These turtles like to bask on logs but hide from extreme heat. Spotted turtles are endangered in Illinois, so if you see one in spring, you’re lucky – just be careful as they may cross roads, especially during mating season.
