Summary:The reactions of spruce grouse to habitat disturbance by logging were studied in northwest Quebec, Canada. Telemetry tracking of 35 spruce grouse before logging and 22 after logging showed that this species is negatively affected by clearcutting. After logging, birds moved to residual stands near their spring home range, choosing regenerating stands with higher shrub densities where available. In unproductive forests, grouse chose habitats with the highest tree density and lowest shrub density. Grouse movements increased during and after cutting. Summer home range size increased during logging compared with size before logging. Resting behavior decreased and alert behavior increased after logging, and overall survival was lower in the year of logging and the year following than in the year before, mainly because of predation.
