Sage grouse are highly selective grazers, choosing only a few plant genera. Dandelion ("Taraxacum" spp.), legumes (Fabaceae), yarrow ("Achillea" spp.) and wild lettuce ("Lactuca" spp.) account for most of their forb intake. From July to September, dandelion comprised 45% of forb intake; sagebrush comprised 34%. Collectively, dandelion, sagebrush, and two legume genera ("Trifolium" and "Astragalus") contributed more than 90% of the greater sage-grouse diet. Insects are a minor diet item for adults. Insects comprised 2% of the adult diet in spring and fall and 9% in summer. Sagebrush made up 71% of the year-round diet.
