Behavior
Eggs
usually 11-13. Whitish to pale buff, finely speckled with brown and olive. Incubation is by female only, 22-24 days.
Young
Downy young leave nest shortly after hatching. Female tends young, but young feed themselves. Young are able to make short flights at age of 1-2 weeks, but are not full-grown for several more weeks.
Feeding Behavior
Forages mostly on ground, sometimes above ground in oaks. May move several miles every day from roosting areas to good feeding sites.
Diet
Includes seeds, acorns, insects, leaves. Diet varies with season. Eats seeds and leaves of a wide variety of plants, including oak leaves and acorns. May eat much waste grain around agricultural fields in fall and winter. Eats many insects, including grasshoppers and beetles, especially in summer. Also eats some flowers, twigs, oak galls.
Nesting
In spring, at dawn and again in evening, males gather on "booming grounds" and display there to attract females. Booming ground on slight rise or level open ground, with good visibility. In display, male raises feather tufts on neck, stamps feet rapidly while making hollow gobbling sounds; may leap in the air with loud cackles. Female visits booming ground, mates with one of the males. Nest site is on ground, usually under a shrub or clump of grass. Nest (built by female) is shallow depression lined with a few bits of grass, weeds.
Climate Vulnerability
Conservation Status
Has disappeared from most of former range and is probably still declining; considered to be threatened. Biggest problem is conversion of natural prairie to farmland.
