Description

Here's my Greater Prairie-chickens in their "booming" grounds. It is known for its mating dance. They are territorial birds and often defend their booming grounds together in a communal lek. These booming grounds are where 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. Due to their now small populations and habitat fragmentation, the greater prairie-chickens often undergo inbreeding, causing observable inbreeding depression: with fewer offspring and a decreased survival rate within these limited offspring further aiding their population decrease. 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.
