Quick Answer
Spruce Grouse do call to each other in winter, typically using a low-pitched, grunting sound to maintain contact and defend their territory. These vocalizations are often heard during the early morning and late evening hours. They also produce a unique drumming display during courtship.
Spruce Grouse Winter Vocalizations
Spruce Grouse are known to emit a variety of sounds, including whistles, grunts, and a peculiar drumming noise produced by beating their wings against the air. In the winter, these calls are more subdued, often consisting of a low-pitched grunt or growl. Research suggests that Spruce Grouse vocalizations change with the season, becoming more frequent and intense during the breeding season.
Drumming and Display Behavior
During courtship, male Spruce Grouse engage in a complex display of drumming and strutting, which includes beating their wings against the ground or against a tree trunk to produce a loud, repetitive noise. This display can last for up to 10 minutes and is accompanied by a distinctive visual display of strutting and posturing. The drumming display is an essential aspect of Spruce Grouse courtship behavior and serves as a means of establishing dominance and attracting a mate.
