Tympanuchus cupido
At a Glance
At one time, the eerie hollow moaning of male prairie-chickens displaying on their spring 'booming grounds' was a common sound across much of central and eastern North America. Today the prairie-chickens are quite uncommon and localized; the race on the Atlantic seaboard, called the Heath Hen, became extinct in 1932. Greater Prairie-Chickens still thrive on a few areas of native grassland in the midwest.

Behavior
Eggs
Usually 10-12, sometimes 7-17. Olive to pale buff, speckled with dark brown. Incubation is by female only, 23-25 days.
Young
Follow female away from nest shortly after hatching. Young find all their own food. Can make short flights at about 2 weeks, stronger flights at 3 weeks. Young usually remain with female for almost 3 months.
Feeding Behavior
Forages mostly on the ground, occasionally in trees. Most feeding in early morning and evening.
Diet
Mostly seeds, leaves, insects. Winter diet is mostly leaves and seeds, also waste grain in agricultural fields. Historically, may have eaten many acorns in winter, and still may do so where they are available. In summer eats a variety of leaves, buds, seeds, berries, and insects. Young birds eat more insects.
Nesting
In spring, males gather on "booming grounds" and display there to attract females. Booming ground often on low hill, with good visibility; typically 8-20 males present, exceptionally up to 70. In display, male lowers head and raises tail, inflates air sacs on neck, raises feather tufts, stamps feet rapidly while making hollow moaning sounds; may leap in the air with loud cackles. Female visits booming ground, mates with one of the males. Nest site is on ground, among thick tall grass. Nest (built by female) is shallow depression lined with grass, leaves, feathers.
Conservation
Conservation Status
Atlantic Coast race (Heath Hen) became extinct in 1932; Texas coast race (Attwater's) is seriously endangered. Loss of habitat is single greatest threat to remaining populations in interior.
