Spring Means Endangered Species Busy Prairie Chicken Boom Means Economy Booms as Well

Jasper County—Spring is the time when young birds’ biological clocks sound the need to reproduce, and the future of many endangered species brightens. People interested in bird watching are fascinated by the sometimes elaborate mating rituals, and many drive hundreds of miles to observe those rituals. One of the most popular locations among bird watchers is the Prairie Ridge State Natural Area in Jasper and Marion Counties, which recently expanded by 226 acres. The area is home to 36 species classified of “special concern,’ including 17 state endangered and 9 threatened species.

“We are fortunate in Illinois to have built up an area that is ideal for the birds,” said Illinois Department of Natural Resources Director Joel Brunsvold. “Significant species flourish at Prairie Ridge State Natural Area, and that is attracting tourists and filling hotel rooms.”

One of the most unique of the species at Prairie Ridge State Natural Area is the Prairie Chicken. The natural area is the most eastern spot inhabited by the species in the United States. In 1860, 14 million of the birds populated Illinois. As settlers developed the state, the birds’ habitat was destroyed. The current Illinois Prairie Chicken population numbers approximately 200.

“The prairie chicken mating ritual is known as ‘booming’ because that’s the noise the male makes to attract females. On a clear day, the boom can be heard for miles. The males also have a dance, they stomp their feet, they puff out orange air sacs and they fluff their tufts of feathers,” said Scott Simpson, site superintendent at Prairie Ridge State Natural Area. “We expect the prairie chicken boom to peak this year between April 7th and 10th.

The prairie chicken requires a large area bare of vegetation as its breeding ground, which IDNR staff prepares by disking the soil. Twelve wetland areas have also been created to provide inviting species habitat. Recent land acquisitions have brought the land area used by all of the species to approximately 3800 acres.

In addition to the Prairie Chicken, species flourishing in the natural area include the North Harrier, short-eared owls, Henslow Sparrows, and the King Rail.

Prairie Ridge State Natural Area is located along Route 70. The birds can be observed from the office area and from the highway, although the site itself is closed because of its classification as a refuge. Birders also can take advantage of the Robert Ridgeway Grassway, which is maintained by the Illinois Audubon Society. The private organization maintains trails and a viewing stand for those interested in observing the birds.

The U.S. Fish and Wildlife Service reports 638,000 people take time to observe wildlife away from home annually in Illinois.
