These comprise the sum of a background mortality risk and a mortality risk attributed to parental behaviour.Conclusions: Mortality is an important parameter in the determination of parental behaviour. As the dependence of the mortality of the young on parental effort grows, a parent should invest a greater proportion of time in being vigilant for predators. An increase in other mortality parameters prompts the opposite effect. Mortality should be described by multiple parameters to predict fully how a parent should behave.",
