Concept
Greater prairie chicken
Summary
The greater prairie chicken or pinnated grouse (Tympanuchus cupido), sometimes called a boomer, is a large bird in the grouse family. This North American species was once abundant, but has become extremely rare and extirpated over much of its range due to habitat loss. Conservation measures are underway to ensure the sustainability of existing small populations. One of the most famous aspects of these creatures is the mating ritual called booming.
Adults of both sexes are medium to large chicken-like birds, stocky with round-wings. They have short tails which are typically rounded. Adult males have orange comb-like feathers over their eyes and dark, elongated head feathers that can be raised or lain along neck. They also possess a circular, un-feathered neck patch which can be inflated while displaying; this, like their comb feathers, is also orange. As with many other bird species, the adult females have shorter head feathers and also lack the male's yellow comb and orange neck patch. Adults are about 16.9 in (43 cm) long, and weigh between 24.7–42.3 oz (700–1200 g). The greater prairie-chicken has a wingspan range of 27.4-28.5 in (69.5-72.5 cm).
There are three subspecies;
The heath hen, Tympanuchus cupido cupido, which was historically found along the Atlantic coast, is extinct. It was possibly a distinct species; in this case the two other forms would be T. pinnatus pinnatus and T. p. attwateri.
Attwater's prairie chicken, T. c. attwateri is endangered and restricted to coastal Texas.
The greater prairie chicken, T. c. pinnatus, is now restricted to a small section of its former range.
Greater prairie chickens prefer undisturbed prairie and were originally found in tallgrass prairies. They can tolerate agricultural land mixed with prairie, but fewer prairie chickens are found in areas that are more agricultural. Their diet consists primarily of seeds and fruit, but during the summer they also eat green plants and insects such as grasshoppers, crickets, and beetles.
