Definition

Noun: A large Arctic and subarctic grouse (a type of game bird) with feathered feet and plumage that typically changes to white in winter for camouflage against the snow.

Usage

The word "ptarmigan" is used to refer to the bird itself. It is a countable noun. * Scientists study how the ptarmigan adapts to extreme cold. * We spotted three ptarmigans during the hike. * The ptarmigan's winter plumage is perfectly white.

Examples

• The ptarmigan is well-adapted to life in the tundra.
• A key survival trait of the ptarmigan is its feathered feet, which act like snowshoes.
• In summer, the rock ptarmigan has a mottled brown plumage.

Advanced Usage

• Collective Reference: While referring to the species or in hunting contexts, "ptarmigan" can sometimes be used as a plural form (e.g., "They hunted ptarmigan."), though "ptarmigans" is also correct.
• In Scientific Context: The word is often used with a species modifier, such as "rock ptarmigan" or "willow ptarmigan."

Variants and Related Words

• Grouse: The broader family of birds to which ptarmigans belong.
• Lagopus: The scientific genus name for ptarmigans, derived from Greek for "hare-footed," referring to their feathered feet.

Synonyms

• Snow grouse (a descriptive, informal name).
• White grouse (another informal name, particularly for its winter form).

Notes on Meaning

The definition focuses on the specific biological characteristics of the bird: its size, habitat (Arctic/subarctic), taxonomy (grouse), and distinctive physical features (feathered feet, seasonal plumage change). It does not refer to anything else.
