Sharp-tailed Grouse
Tympanuchus phasianellus
At a Glance
The Sharp-tailed Grouse is typical of regions that have open grassland mixed with groves of trees or shrubs. Closely related to the prairie-chickens, it is found mostly farther north. On winter nights it may roost by burrowing into snowdrifts, where the snow helps insulate it from the cold.

Behavior
Eggs
5-17, typically about 12. Olive-buff to pale brown, usually speckled with various browns. Incubation is by female only, about 23-24 days.
Young
Downy young leave nest shortly after hatching. Female tends young and leads them to feeding areas, but young feed themselves. Young can make short flights at age of 1-2 weeks, but are not full-grown for several more weeks.
Feeding Behavior
Forages mostly on ground in summer, mostly in trees and shrubs in winter.
Diet
Mostly seeds, buds, leaves. Mostly vegetarian for most of year. In winter, when food on ground is mostly buried by snow, feeds heavily on buds of trees and shrubs. In spring, eats leaves, green shoots, large numbers of flowers. Varied diet in fall, with seeds, berries, leaves, waste grains. Insects eaten mainly in summer (especially by young birds), including many grasshoppers.
Nesting
In early mornings in spring, males gather on display ground. Male points tail up, spreads wings, holds head low, stamps feet rapidly while moving forward or in circles. Male inflates neck sacs, then deflates them with hollow cooing sound; also rattles tail feathers. Female visits display grounds, mates with one of the males. Nest site is on ground, under shrub or thick clump of grass. Nest (built by female) is a shallow depression with a sparse lining of grass, leaves, ferns.
Climate Vulnerability
Conservation Status
Has disappeared from some parts of former range (especially southern areas), and may still be declining. Loss of habitat is main cause.
