Comments: Sage-grouse diet consists of almost exclusively sagebrush in winter; during the remainder of the years Gunnison sage-grouse eat sagebrush, forbs, and insects (Wallestad et al. 1975, Schroeder et al. 1999, Young et al. 2000). Insects are important in the diet of chicks during their first three weeks of life; subsequently, forbs and sagebrush increase in importance (see Gunnison Sage-grouse Rangewide Steering Committee 2005).
