Lesser Prairie-Chicken

Adult individuals are medium to large birds, striped white and brown like its near relative, the Greater prairie-chicken (T. cupido), though it is smaller and paler. Adults range from 15.0 to 16.1 inches (38 to 41 cm) in length and 22.1 to 28.7 ounces (630 to 810 g) in weight. Mature males sport yellow, comb-like feathers above each eye, as well as long head feathers that can be raised to show their pinkish-red Gular sacs. One is present on each side of the neck, which becomes inflated to be used in mating displays.

About half of its current population lives in western Kansas, with the other half in the sandhills and prairies of western Oklahoma, the Texas Panhandle including the Llano Estacado, eastern New Mexico, and southeastern Colorado. They prefer environments containing sand sagebrush and shinnery oak, as well as various grasses and shrubs depending on the area.

Like its larger relative, it is known for its lekking behavior, particularly the "booming" call produced during mating displays. They typically prefer wide, open areas such as hills and ridges with short grass for their leks, however the use of man-made structures such as roads or oil platforms has also been observed. During the months of April and May, males will establish an area for themselves and potential mates, and will typically become territorial as the spring season progresses. This process is repeated to a lesser degree in the fall, beginning as early as late August and reaching a height in October. Males in particular are likely to return to the same territory repeatedly. Females will begin nesting following mating, most frequently in May. Nests are dug about 5–10 cm into the ground, with a width of up to 20cm. These nests are lined with grasses, leaves, and feathers, and may be located within taller grasses or beneath brush and shrubs for shade and shelter. A single brood usually contains 11–14 eggs, hatching about 23 days after being laid. Chicks become fledged within 4 weeks, and after 8–10, will be left on their own as the mother hen leaves to molt.
