Attwater's prairie chicken (Tympanuchus cupido attwateri) is a highly endangered subspecies of the greater prairie chicken that is native to coastal Texas and Louisiana in the United States.
Attwater's prairie chicken measures 17-18 in (43-45.5 cm) and weighs roughly 1.5 to 2.0 lb (0.7 to 0.9 kg). It has a 28-in (70-cm) wingspan. These grouse have strong vertical bars of dark brown and buff-white pattern over the mantle, flanks, and underparts. The species exhibits sexual dimorphism, with the males having elongated feathers, called pinnae, erected to form what looks like ear-like structures. The male also has as a bright orange or golden air sac on either side of his neck, which he inflates during mating displays. They have a lifespan of two to five years.
T. c. attwateri is endemic to the Western Gulf coastal grasslands. Its range historically stretched yass from Bayou Teche in Louisiana to the Nueces River in Texas, possibly as far south as Tamaulipas, Mexico, and inland for 75 mi (121 km). This covered an area of 6 million acres (24,000 km²). Today, populations exist in the wild at two locations: the Attwater Prairie Chicken National Wildlife Refuge near Eagle Lake, Texas, and on private lands in Goliad County.
The mating display can be seen January through mid-May, peaking in mid-March, when the birds gather in small groups on short grass, bare ground, or hilly areas to choose a mate. This area is called a lek or "booming ground." In these areas, the females watch the males and choose their mate. The male emits a booming, "woo-woo" sound from his neck sac and struts around to attract a female. Some of the traditional dances of the North American Plains Indians are based on this booming display.
