The Greater Prairie-Chicken is a large bird in the grouse family. Greater Prairie Chickens prefer undisturbed prairie and were originally found in tall grass prairies. They can tolerate agricultural land mixed with prairie, but the more agricultural land the fewer prairie chickens. Their diet consists primarily of seeds and fruit but during the summer they also eat insects and green plants. Greater Prairie Chickens do not migrate. They are territorial birds and often defend their booming grounds. These booming grounds are the area in which they perform their displays in hopes of attracting females. Their displays consist of inflating air sacs located on the side of their neck and snapping their tails. These booming grounds usually have very short or no vegetation. The male prairie chickens stay on this ground displaying for almost two months. The breeding season usually begins in the United States starting in Late March throughout April. During this time the males establish booming sites where they display for the females. The one or two most dominant males will do about 90% of the mating. After mating has taken place, the females will move about one mile from the booming grounds and begin to build their nests. Hens lay between 5 and 17 eggs per clutch and the eggs take between 23 and 24 days to hatch. There are between five and 10 young per brood. The young are raised by the female and fledge in one to four weeks, are completely independent by the tenth to twelfth week, and reach sexual maturity by age one. One problem facing prairie chickens is competition with the Ring-necked Pheasants. Pheasants will lay their eggs in prairie-chicken nests. The pheasant eggs hatch first; this causes the prairie chickens to leave the nest thinking that the young have hatched. In reality the eggs did not hatch and the young usually die because the mother is not there to incubate the eggs.
