Greater Prairie Chicken

This North American grouse species was once widespread all across the oak savanna and tall grass prairie ecosystem. The Greater Prairie Chicken almost became extinct in the 1930s due to hunting and habitat loss.
In March through April the males establish "booming" sites where the males display for the females, inflating air sacs located on the side of their neck. In Britain we call this "lekking" where males of the Black Grouse establish Leks. Unfortunatelly also a rare bird. There are two other species in North America.
