Comments: Activity occurs throughout the year, primarily during daylight hours.
Mating activity peaks shortly after sunrise but occasionally occurs near sunset or during nights with bright moonlight (Schroeder et al. 1999).
During the mating season, sage-grouse forage in morning after breeding activity and in afternoon before roosting or breeding activity (Schroeder et al. 1999). During nesting season, females remain on nests throughout most of the day and night, but they take brief foraging breaks during morning and late afternoon or evening (Girard 1937).
In summer, sage-grouse forage in early morning, loaf during midday, and forage again in the afternoon (Nelson 1955).
