If you’ve ever heard someone calling out in the woods, “Who cooks for you?” there’s probably a barred owl nearby. These distinctive-looking owls are best known for their hard-to-miss call, which sounds like they are calling out: "Who cooks for you? Who cooks for you all?"

Boa constrictors are among the most well-known snakes in the world thanks to how they are portrayed in popular culture. If the movies were to be believed, boa constrictors are a major threat to people. The reality is a little different.

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.

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.

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.
