Description
The state bird of Pennsylvania, the ruffed Grouse is well-equipped for cold winters with snowshoe-like extensions on its toes. The northern birds depend on snow as a place to roost in the winter, burrowing at night into snowdrifts for insulation and shelter.

Feeding Habits
Ruffed Grouse's diet consists primarily of vegetation, such as leaves, buds, and fruits of ferns, shrubs, and woody plants. In fall, they eat more soft fruits and acorns. They survive winter by eating buds and twigs, especially of aspen, birch, and willow in the north, and green plants like greenbrier and mountain laurel in the south. Chicks rely heavily on protein-rich insects and other invertebrates.
Habitat
Ruffed Grouse thrives in a diversity of wooded environments, particularly favoring transitional areas rich in a mix of young and mature trees. They are inclined towards mixed-age groves of aspen, spruce, and birch in northern locales, whereas southern populations often reside in deciduous forests with an abundance of oaks, hickories, and pines. Altitudinal preference isn't highly specific, but ruffed Grouse shows a partiality for forests offering dense understory for cover and fruiting shrubs for sustenance. Habitats disrupted by natural or human activities can be favorable by producing early-successional woodlands. Conversely, mature, undisturbed forests or small wooded areas amidst agriculture are less suitable for sustaining healthy ruffed Grouse populations.
Nest Behavior
The female builds the nest, plucking vegetation to line it. Egg-laying typically follows completion, and she is solely responsible for the incubation and care of the chicks once hatched.
Nest Characteristics
Ruffed Grouse constructs nests at the base of trees, stumps, rocks, or in brush piles, with a preference for views clear of obstruction for predator spotting. The nest is a shallow, bowl-shaped depression up to 6 inches wide and 3 inches deep, lined with leaves and plucked vegetation.

General Info
Behavior
Ruffed Grouse are masters of camouflage, using their cryptic coloring to blend into their forest environment while foraging on the ground or picking berries from branches. They are typically solitary, only forming groups when foraging sites are abundant. Their daily life involves meticulously roosting in snow for insulation, a behavior that can startle passersby when they burst out. Males have a distinctive courtship display involving erect crests and tails, and a drumming performance to attract females and challenge rivals. Post-mating, females independently nest and rear chicks. Ruffed Grouse behaviorally adapt to seasonal changes and their forest habitat, ensuring their survival and reproductive success.
