The Greater Prairie ChickenA Wisconsin Wildlife Success Story
In the April dawn, when the morning air is crisp and the sky lightens to a cool pink, open fields on Buena Vista Marsh come alive with wild voices. It is the annual mating ritual of the greater prairie chicken, an activity known as "booming." This primitive ceremony pits bird against bird as male chickens stake out territory to attract hens for mating. The performance takes its name from the distinctive sound made by the male chicken, a deep and resonant three-noted "whoo,whoo, whooooo" accompanied by whoops and cackles that signal territorial possession. The loud booming call and ritualistic fighting of the birds as they jump, flutter and square off against each other is punctuated by the sound of prairie chicken feet beating double time in a performance that inspired the species' scientific name, Tympanuchus cupido pinnatus, or "drummer of love." Other names for this bird include pinneated grouse, prairie hen, and old yellowlegs. Greater prairie chickens are unique to the grasslands of North America and are found nowhere else. These birds were once abundant in the New World and widely hunted for food and sport. Farm activity and small settlements began to push westward into the prairies and plains of middle America which changed the grasslands. The birds benefited from the landscape changes from logging and early farm practices, however, the amount of open grasslands they needed decreased, and market hunting practices were too destructive. This significant loss was noted in the 1850s and Wisconsin game laws were set to limit the open season for prairie chickens. Eventually, populations became too small for hunting as the prairie chicken range was narrowed to central Wisconsin.
Buena Vista Grasslands is open to the public and available for teachers and students to learn more about these birds. Each spring, observation blinds at Wisconsin's prairie chicken management sites are available for mature and hardy bird watchers to participate in research as they witness the booming ritual in the hours near dawn. April is the ideal time and reservations for small groups can be made through the University of Wisconsin - Stevens Point by calling 1-877-269-6626 (toll-free) or 715-346-3259. Also, check out the unique roadside exhibit where you can hear the sweet sounds of grassland birds and the distinctive deep resonating "whooo" of the prairie chicken's call from a sound box at the display. It also includes many colorful photographs of area songbirds, the natural history of the prairie and prairie chicken, and the management of this unique ecosystem.
