Greater Prairie-Chicken

The Greater Prairie-Chicken is a medium-to-large, stocky grouse native to the grasslands of North America. Once exceedingly abundant across the tallgrass prairie ecosystem, their populations have contracted severely due to habitat loss, making them a key target species for conservationists and birdwatchers alike. They are renowned for their highly synchronized and dramatic communal breeding behavior, which takes place on traditional display arenas.

Greater Prairie-Chickens are stocky, chicken-like birds with an overall pale brown body covered in heavy, dark horizontal barring. They possess short, dark, rounded tails.

• Breeding Males: Feature prominent, elongated neck feathers called pinnae, which they can erect like rabbit ears. They have bright yellow-to-orange fleshy combs above their eyes and spectacular, circular orange-yellow air sacs on the sides of their necks that inflate during displays.
• Females: Slightly smaller and lack the inflatable air sacs. Their pinnae are much shorter, and their tails are barred brown and black rather than solid dark brown.
• Similar Species: The Lesser Prairie-Chicken is smaller, paler, and has rosy-red rather than orange-yellow neck sacs. The Sharp-tailed Grouse distinguished by its white-spotted wings, wedge-shaped pointed tail, and V-shaped markings on its underparts instead of horizontal barring.

Historically, this species occupied the vast tallgrass prairie belt stretching from Alberta to Texas and east into the Ohio River Valley. Today, they are restricted to fragmented pockets of native tallgrass and mixed-grass prairies, agricultural fields, and oak savannas. They require large, contiguous tracts of grassland with varied vegetation heights: short grasses for displaying, and taller, denser cover for nesting and raising broods. Major modern strongholds are located in Kansas, Nebraska, South Dakota, and portions of Minnesota.

The behavior of the Greater Prairie-Chicken is dominated by their breeding cycle.

• Lekking Displays: From March to May, males gather on communal display display grounds called 'leks' at dawn. They defend small individual territories by stomping their feet in rapid succession, running forward, raising their pinnae, inflating their orange neck sacs, and producing a resonant, low-pitched 'booming' sound that resembles the sound of blowing across the top of an empty glass bottle. This sound can carry for over a mile.
• Diet: During the summer, they eat insects (especially grasshoppers, beetles, and caterpillars), which are vital sources of protein for growing chicks. In winter, they transition to eating seeds, grains, leaves, and buds of woody plants, sometimes feeding in agricultural fields to survive harsh weather.
• Nesting: Females build a shallow scrape on the ground, carefully hidden under dense overhangs of grass or low shrubs. They line the nest with grass, leaves, and feathers, laying a single clutch of 4 to 15 eggs.
