Description

The Ruffed Grouse is a medium-sized, robust forest dweller famous for its dramatic spring drumming display, where males beat their wings rapidly to create a low-frequency sound that resonates through the woods.

Colour & Pattern

Intricate barred pattern with rich brown, black, and buff tones, featuring a prominent pale central shaft streak bordered by dark markings.

Barb Structure

Pennaceous tip with tightly interlocked barbicels transitioning into a fluffy, plumulaceous base with a distinct downy afterfeather.

Texture & Surface

Smooth and firm at the patterned tip, transitioning to soft and silky at the plumulaceous base.

Key Features

Distinctive dark and light barring, a pale central rachis line flanked by dark V-shaped markings, and a fluffy downy base.

Habitat

Deciduous and mixed forests with dense undergrowth, brushy areas, and clearings.

Geographic Range

Widespread across forested regions of North America, extending from Alaska and Canada down through the northern and mountainous United States.

Ecological Role

Serves as an important prey species for various forest raptors and mammalian carnivores, and acts as a key indicator of healthy, diverse early-successional forest ecosystems.

Similar Species

Spruce Grouse or Sharp-tailed Grouse, distinguished by different banding patterns and coloration details.

Interesting Facts

Ruffed Grouse grow specialized comb-like projections on their toes called pectinations in the autumn, which act as natural snowshoes to help them walk on top of deep winter snow.

Condition Notes

Good condition, showing minor natural wear at the tips but retaining full structural integrity.

Notes

Found in the abandoned nest of a northern house wren, in northern Manitoba
