As the seasons change and warmer weather arrives, I always feel a little lighter and my smile becomes a bit brighter. With trees awakening and the sounds of more birds outside my window, I’m grateful for the extra moments of sunshine and I enjoy watching the furry friends in my neighborhood. Springtime welcomes back life with migrating birds, the birth of young mammals, and the mating calls of amphibians. As we experience springtime once again, here are a few animals to be on the lookout for.
Wood-warblers
Wood-warblers are small migratory birds, and there are nineteen wood-warbler species known to breed in Illinois. They are brightly colored, specifically in shades of yellow, with variations in head and wing coloration that help distinguish between various species. Catching a glimpse of these vibrant birds is a special treat during spring migration. They depend on forests for their habitat and migrate south in the winter when food sources become scarce due to a decrease in insects. Pine warblers, yellow-rumped warblers, and the common yellowthroat are just a few of the wood warblers you may see this spring. Wood warblers are also known for their unique calls.

River Otters
Young river otters are born between February and May. At around one month old, they open their eyes, and by four months, they can swim and dive to catch their own food. River otters are active both during the day and at night. They move more easily in water than on land as they are quick swimmers, and their tail helps them maneuver underwater. Families of otters can often be found in rivers, streams, and lakes, where they feed on fish, crayfish, and other creatures such as frogs, snakes, and aquatic invertebrates. Watching young river otters play in the water or along the bank is a fun springtime sight.
American Toads
American toads are a distinctive sound of spring across Illinois, except for in the southeastern corner of the state. These toads are nocturnal and breed in the spring. The males call out with a high musical trill to attract mates from mid-April to early May but may continue calling through late summer. This call can be heard from almost every aquatic habitat. Female American toads lay several thousand eggs, which hatch within a week. The tadpoles then transform into toads within 40 days.
The sights and sounds of wildlife in the spring bring excitement to the changing seasons. Step outside, explore, and experience the return of life this spring season.
