Herons in Illinois: Where to See Them and How to Identify Them

Where in Illinois are herons most likely to be seen?

Herons show up in every Illinois county, but the best places are large wetlands and major waterways. The Illinois River backwaters around Starved Rock State Park are reliable, as are the Emiquon Preserve and the Cache River Wetlands in the south. Along Lake Michigan, Montrose Harbor and the Chicago lakefront can turn up herons during migration. Smaller ponds and farm drainage ditches also hold them, especially Great Blue Herons. For a full guide to top spots, see ourIllinois wildlife page.

What is the best season and time of day to see herons?

Spring and summer are prime time for most species. Great Blue Herons arrive in March and stay through October, and some linger near open water all winter. Green Herons and night-herons come in April and leave by September. Early morning and late afternoon give the best light and most active feeding. On hot summer days, herons often rest in the shade at midday, so plan your trip around dawn or dusk.

How can you identify the different heron species in Illinois?

Start with size and color. Great Blue Heron stands about 4 feet tall with a gray-blue body, long neck, and a black stripe that extends from the eye to the back of the head. Green Heron is much smaller (about the size of a crow) with a dark cap and reddish chest. Black-crowned Night-Heron is stocky with a black back and red eyes; Yellow-crowned Night-Heron has a pale yellow crown and gray body.

What habitats do herons prefer in Illinois?

Herons need shallow water to hunt. They use marshes, swamps, flooded fields, lake edges, and slow-moving rivers. Great Blue Herons will also stalk crayfish in farm ditches and pond edges. Night-herons prefer dense brush along shorelines. For the best odds, look for areas with a mix of open water and emergent vegetation like cattails and bulrushes.

Are there any rare heron species to look for in Illinois?

Yes, a few less common herons appear each year. Little Blue Herons show up in spring and fall, usually in the southern half of the state. They look all dark as adults, white as juveniles. Tricolored Herons are slender with a white belly and can be seen along the Mississippi River. Reddish Egrets are very rare, but a few have been spotted at Lake Michigan beaches. Check eBird for recent reports before heading out.

What behaviors should you watch for when spotting herons?

Herons are patient hunters. They stand still or walk slowly in shallow water, then stab fish or frogs with a quick thrust of their bill. When flying, they fold their necks in an S-shape and beat their wings slowly. Great Blue Herons often nest in colonies called rookeries, usually in tall trees near water. If you find a rookery, watch from a distance to avoid disturbing them.

How can you photograph herons in Illinois?

A telephoto lens of at least 300mm helps you keep distance without scaring them. Wear dull colors and move slowly. Early morning light gives warm tones. If you see a heron feeding, stay put and wait for it to come closer. Many public wetlands have blinds or viewing platforms that let you get close without being seen.
