Proximate red coloration in males due males seeking out to carotenoid-rich foods; Positive correlation between father and son coloration: ultimate red coloration in males positively correlated with mating success (attracts mates 2-3xfaster) Benefits of coloration 1) recovery from infection 2) care for offspring 3) offspring coloration (fitter offspring: variation due to proximate and ultimate causes. Males seek out carotenoid rich foods (proximate; causes within-population variation) Males who can afford to seek out carotenoid food instead of energy must be better quality. Animal behaviour self generatd movement of either a body part of whole body in animals.
