The Sharp-tailed Grouse (Tympanuchus phasianellus) is a medium-sized bird native to the grasslands and prairies of North America, particularly in Canada and the northern United States. Named for its pointed, sharp tail feathers, this grouse has mottled brown, white, and black plumage that provides excellent camouflage in its open habitat. During the breeding season, males perform spectacular courtship displays, known as "dancing grounds" or leks, where they stamp their feet, fan their tails, and emit distinctive cooing sounds to attract females. The Sharp-tailed Grouse feeds on a variety of plants, seeds, and insects, depending on the season, and is an important species in grassland ecosystems.
