Herons in Kansas: where to see them and how to identify them

Herons in Kansas gather around shallow water with good fishing. Cheyenne Bottoms, a major inland wetland, hosts large numbers. Quivira National Wildlife Refuge is another stronghold. Smaller marshes and farm ponds across the central and eastern part of the state also attract them. Look for them along the Arkansas River and at state fishing lakes.

Spring and fall migration bring the most herons through Kansas, from March to May and September to October. Early morning and late afternoon are the best times, when herons are actively feeding. In summer, they breed in colonies, so dawn patrols near rookeries can be very productive.

Great Blue Herons are the largest, with a gray-blue body, long legs, and a yellow bill. They stand still in water, then strike quickly. Smaller Green Herons have a chestnut neck and greenish back. Black-crowned Night Herons are stockier with red eyes and a black crown. Compare size and plumage to tell them apart.

Besides the Great Blue Heron, look for the Little Blue Heron (dark with a two-toned bill), the Cattle Egret (often in fields with livestock), and the Great Egret (white with black legs and yellow bill). The American Bittern, a secretive heron relative, also lives in Kansas marshes.

Move slowly and listen for loud, raspy calls. Scan the edges of reeds and cattails where herons stalk fish. Use binoculars to pick out the long neck and dagger-like bill. Many herons freeze when they sense movement, so pause often. A scope helps at large wetlands like Cheyenne Bottoms.
