The term "Perdrix" (in French) or "partridge" (in English) is generally attributed to birds of the order Galliformes and the family Phasianidae. This species has two sub-families:

• the tetraonines, represented by ruffed grouse, the most widespread, designated "partridge of hardwoods"; the spruce grouse (or spruce grouse) referred to as the "fir partridge"; willow ptarmigan and rock ptarmigan (or rock ptarmigan), referred to as "white partridge";
• phasianines, including the gray partridge (or Hungarian partridge), of Eurasian origin, which is established in certain parts of Quebec.

The toponym Perdrix River was formalized on December 5, 1968, at the Commission de toponymie du Québec, i.e. at the creation of this commission.
