Overview

Ruffed Grouse: Medium-sized grouse with crested head and scaled brown upperparts. White underparts have pale brown bars on breast and dark brown bars on belly and flanks. Sides of neck have black ruff. The tail is brown with fine, white bars and white-edged dark band at tip. Northern form is grayer.

Ruffed Grouse: Resident from the tree line in Alaska and northern Canada south to California, Wyoming, Minnesota, and the Carolinas; also found in the Appalachians to Georgia. Declining in the East. Preferred habitat includes overgrown pastures and deciduous and mixed forests, especially those with scattered clearings and dense undergrowth.

Voice Text

"quit-quit"

• Male Ruffed Grouse cup their wings and rapidly beat them against the air. Native people called it the “carpenter bird” because they thought the sound was made by beating its wings against a log.
• Their population numbers cycle every 8-11 years with respect to population numbers of their predators—the fox, Northern Goshawk and Great Horned Owl.
• This state bird of Pennsylvania is well-adapted for winter with lateral extensions of the scales on their toes almost like snowshoes.
• A group of grouse has many collective nouns, including a "chorus", "covey", "drumming", "grumbling", and "leash" of grouse.

• Spruce Grouse

Partridges, Grouse, Turkeys and Old World Quail (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

Partridges, Grouse, Turkeys and Old World Quail 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 Indian 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

Partridges, Grouse, Turkeys and Old World Quail 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.
