Diets and Food Selection of Sage Grouse Chicks in Oregon

Diets and food selection by sage grouse (Centrocercus urophasianus) chicks were determined during 1989 and 1990 on 2 areas that differed in long-term grouse productivity. Chicks consumed the same foods in similar frequencies and exhibited similar dietary selection on the areas, but relative dry mass differed. Forbs and invertebrates composed 80% of the dietary mass on the area with higher grouse productivity, whereas chicks on the other area consumed primarily (65%) sagebrush Artemisia spp. L.).
