The effects of nuptial colour, parasites and body size on reproductive success were examined in a natural population of three‐spined stickleback Gasterosteus aculeatus . Reproductive males were collected, with the contents of their nests, during the embryo‐guarding stage from Lynne Lake (Cook Inlet, Alaska, U.S.A.), and nuptial colour, infection status and body size were recorded. Regression analysis revealed that male body size was the only predictor, of those measured, of reproductive success in nature.
