Lay SummaryThe factors that limit sexual signal expression and ensure honest signaling of mate quality are poorly known. We show that predation risk is a cost of the sexually selected red coloration of the threespine stickleback and, hence, could contribute to signal honesty. A common predator selectively preys on colorful stickleback males in the field, and an experimental study showed that the bright coloration attracts the predator independent of the behavior of the male.
