Description:
This 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. he authors examined crops from 222 California Quail collected in 197678 and 1985-87. iets included 14 key plant foods (annual frequency >15%) among 53 taxa consumed; 10 of the 14 key foods were similar between time periods. ollectively, key foods contributed 87% of the diet by aggregate dry mass during 1985-1987, six species of legumes (family Leguminosae) composed 670-. of diet. elative rankings of availabilities of key foods were similar between 197678 and 1985-87. his study revealed that quail were opportunisticwithin the group of key foods because 9 of the 14 key foods ere consumed in different frequencies between the two periods. egumes 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.
