Sharp-tailed Grouse (Birds of Lost Lake Peatland SNA)

Sharp-tailed Grouse

Tympanuchus phasianellus

Summary ²

General description: The sharptail is a large grouse, somewhat larger than the ruffed grouse, that lives in open grassy or brushland areas.

Length: Between 15 and 20 inches.

Weight: Between two and three pounds.

Color: Sharp-tailed grouse are a mottled brown and gray. During spring, the male's eyebrows are yellow and its air-inflated throat sacks are lavender.

Sound: A cackle while flying. During spring mating season, males will try to attract females by making coos and clucks, stomping their feet, and clicking their tail feathers.

Reproduction
To attract a female for mating, male sharp-tailed grouse perform a courtship dance. Each spring, as many as 25 males gather in a grassy area and begin to display. The same dancing ground, called a lek, is used each year if the habitat remains unchanged. Females visit the lek and mate with the best displaying male. The female nests in grass or beneath a shrub, usually near the dancing area and lays 10 to 14 eggs.

Food
During the summer and fall, sharptails eat a variety of weed seeds and small grain. During the winter, buds and twig ends of arctic birch, paper birch and aspen are favored. Chicks eat mainly insects during the summer.

Predators
Great horned owls, goshawks, foxes, skunks and raccoons all hunt and eat sharptails.

Range and range
Large open areas with grass, brush and some trees in northwestern and east-central Minnesota. If trees begin growing up in the open areas, the sharptails abandon this habitat.

Population and management
The once-thriving sharp-tailed grouse population has declined sharply in the last 50 years. The reason for this has been the loss of grassland and brushland habitats. Controlled burning and tree clearing has helped prevent some open brushlands and grasslands from turning into woodlands. This has helped sharptails.
