Ruffed Grouse

Overview

The Ruffed Grouse is a forest-dwelling gamebird widespread across northern and eastern North America, found in deciduous and mixed woodlands. It occurs in two main color morphs, red and grey, both showing intricate mottled camouflage patterning. Males are known for their neck ruffs, feather tufts flared during a distinctive non-vocal drumming display performed on logs.

• Family: Phasianidae (grouse)
• Diet: buds, leaves, seeds, and invertebrates
• Range: Canada and the northern and Appalachian United States

Feather Identification

• Body feathers: intricately mottled in brown, buff, black, and grey, providing excellent camouflage against leaf litter and bark.
• Ruff: elongated black or dark brown feathers on the neck sides can be raised into a prominent ruff during display, giving the species its name.
• Tail: the fan-shaped tail shows fine barring with a bold dark subterminal band near the tip, a key identification feature for shed tail feathers.
• Color morphs: red morph birds show warmer rufous-brown tones overall, while grey morph birds are cooler grey-brown; both share the same tail banding pattern.
• Vs. similar species: the combination of a broad, banded fan tail and neck ruff feathers distinguishes it from other North American grouse such as the Spruce Grouse, which lacks the prominent dark tail band and ruff.

Plumage Notes

Both sexes show similar mottled plumage, though males have slightly larger, more developed ruffs and a more complete dark tail band, useful but not always reliable for sexing. Juveniles resemble adults but with softer, less defined patterning until their first full molt. Red and grey color morphs can occur within the same population and are not linked to sex or age.

Habitat & Range

Ruffed Grouse inhabit deciduous and mixed forests, especially areas with aspen, birch, and dense understory, across Canada and the northern and Appalachian United States. They are non-migratory, remaining within a home range year-round, though winter habitat use may shift to denser cover.

Behavior

Ruffed Grouse forage on the ground and in trees for buds, leaves, seeds, and fruit, supplemented with invertebrates, especially in the breeding season. Males perform a distinctive "drumming" display, rapidly beating their wings while standing on a log to produce a deep, accelerating thumping sound rather than a vocal call. Nests are shallow ground scrapes concealed by vegetation. The species is generally solitary outside of the breeding season.
