Technical note: iets and food selection of sage grouse chicks in Oregon.

M.S. Drut, W.H. Pyle, J.A. Crawford


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.).
