From: The oxidative balance and stopover departure decisions in a medium- and a long-distance migrant
The probability that a migrant departed from our stopover study site the night after capture in relation to its malondialdehyde (MDA) concentration, a marker of oxidative lipid damage, and its total non-enzymatic antioxidant capacity (AOX), corrected for uric acid (UA) concentration. A one means the bird departed and a zero means the bird stayed. The top two panels represent northern wheatears (Oenanthe oenanthe) (n = 93 for MDA and n = 92 for UA-corrected AOX) and the bottom two panels represent song thrushes (Turdus philomelos) (n = 78). Individual data points are jittered to reduce clumping. To reduce the number of zeros after the decimal point, UA-corrected AOX was multiplied by 1,000. Bird photos by TK
