Figure 4. A). Lipid hydroperoxide concentration andB). Oxygen radical absorbance capacity (ORAC) (means ± standard error; Table S4) in the liver and pectoralis muscle of European starlings that were or were not flown in the wind tunnel for 15 days, Flight-trained (N=49) or Untrained (N=40), respectively. Flight-trained birds had lower levels of lipid hydroperoxides in the liver compared to untrained birds but there were no differences in the pectoralis related to flight training. There were no significant differences in hydroxyl or peroxyl scavenging capacities between flight-trained and untrained birds in the liver or pectoralis. Asterisks correspond to significance levels: *p<0.1, **p<0.05 , ***p<0.01
