Data from: A small badge of longevity: opposing survival selection on the size of white and black wing markings
According to handicap principle, exaggerated ornamental traits are supposed to exert costs on their bearers. However, there is much less theoretical and practical consensus about whether and under which conditions ornament expression should positively correlate with survival. We measured age-related...
