The study was designed to describe dietary changes by comparison of information on long-term diet and plant food availability of California Quail (Callipepla californica) in western Oregon. The authors examined crops from 222 California Quail collected in 1976-78 and 1985-87. Diets included 14 key plant foods among 53 taxa consumed; 10 of the 14 key foods were similar between time periods. Collectively, key foods contributed 87% of the diet by aggregate dry mass during 1985-1987, six species of legumes (family Leguminosae) composed 67% of diet. Legumes were an important dietary component in western Oregon because they composed the bulk of the diet, were among the most frequently consumed, and most were taken in substantially greater portions than available.
