Fig. 1. Percentage of dietary fat and furcular fat in birds composed of saturated and unsaturated fat for red-eyed vireos fed the 58%U and 82%U diets. Values are means ± S.E.M. (diet N=3, fat N=5). Inset white line within each bar is the percentage of dietary fat and furcular fat in birds composed of 18:2n6 fatty acid (S.E.M. is less than bar width). Different letters above the bars denote significant differences (P<0.05) in percentage unsaturated fat and 18:2n6 between diet groups.
