Overview
Sharp-tailed Grouse: Medium grouse with lightly barred brown upperparts and white underparts dotted with chevrons. Head has short crest, yellow-orange eye comb, and pink or violet neck patch exposed when displaying. Tail is pointed and white-edged. Often seen on prairies in the summer.
Range and Habitat
Sharp-tailed Grouse: Resident from Alaska east to Hudson Bay and south to Utah, northeastern New Mexico, and Michigan. Found in brushlands, grasslands, sagebrush, woodland edges, brushy prairies, cleared farmlands, bogs, river canyons, and boreal forest edges.
Turkeys and Grouse (Phasianidae)
ORDER
An order of five families found on most continents (some taxonomic systems only recognize four of these, classifying the fifth as a sub-family), the GALLIFORMES (pronounced gal-lih-FOR-meez) include “fowl” like birds such as guineafowl, pheasants, grouse and turkeys, and the wild ancestor to the domestic chicken.
FAMILY TAXONOMY
Turkeys and grouse are members of the Phasianidae (pronounced fah-see-AH-nih-dee), a family of one hundred and eighty-seven species in fifty-six genera found on all continents except for South America and Antarctica.
NORTH AMERICA
In North America, the Phasianidae is represented by twenty-six species in seventeen genera. This total includes several introduced and native species such as the Wild Turkey, prairie chickens, and various species of grouse.
KNOWN FOR
The Phasianidae are known for their elaborate courtship displays that frequently utilize raised tails that are spread to reveal intricate patterns. Male Sage Grouse, Sharp-tailed Grouse, and prairie chickens take these displays a step further by displaying communally at traditional “lekking “ sites where birds inflate prominent neck and chest patches that produce loud, popping sounds.
PHYSICAL
The Phasianidae range in size from the small Japanese Quail to one of North America’s largest bird species; the Wild Turkey. Regardless of size, all members of this family have stout bills, long, strong legs and short wings that attest to a mostly terrestrial lifestyle. Several species also have fairly long tails that are adaptations for their courtship displays.
COLORATION
Aside from the radiant, iridescent plumages of male Common Peafowls and some pheasant species, most of the Phasianidae exhibit barred and streaked patterns in tones of brown and black that match their terrestrial habitats, thus providing these birds with excellent camouflage. In winter, the ptarmigans molt from such brown and gray dominated plumages into mostly white plumages to match their snowy environments. Bright colors in native North American species are restricted to bits of red, orange, and purple found on the necks and heads of some members for display purposes.
GEOGRAPHIC HABITAT
In North America, the members of the Phasianidae occur in tundra, grasslands, and forest. Three species of ptarmigan crouch in the far northern tundra and alpine habitats of the Rocky Mountains while the sage-grouse, Sharp-tailed Grouse, and prairie chickens display in sagebrush and grasslands of the west. Deciduous and coniferous forests are home to the Wild Turkey and four grouse species. Introduced species live in a variety of Hawaiian habitats while the Ring-necked Pheasant is now common in North American grasslands.
MIGRATION
Aside from occasional short-distance migration by the ptarmigans of the far north, species in the Phasianidae spend all four seasons in the vicinity of their breeding grounds.
HABITS
Turkeys, grouse, and other members of this family often flock together to forage for small creatures, seeds, and buds. Most look for food on the ground although the Spruce Grouse also forages in the trees for pine and spruce needles.
CONSERVATION
Although populations of Wild Turkeys have made a wonderful, successful comeback since their decline earlier in the twentieth century, all five species of grouse that occur in sagebrush and grasslands (sage-grouse, Sharp-tailed Grouse and prairie chickens) have threatened and declining populations. These declines are due to degradation and conversion of their grassland habitats to agriculture and other development.
INTERESTING FACTS
To aid in walking in their snowy winter environments, Ruffed Grouse and ptarmigans have evolved “natural snowshoes”. In Ruffed Grouse, scales on their toes have extensions to keep them from sinking into snowdrifts, while ptarmigans have a profusion of feathers on their feet for this purpose.
