Data from: Early mortality saves energy: estimating the energetic cost of excess offspring in a seabird
Offspring are often produced in excess as insurance against stochastic events or unpredictable resources. This strategy may result in high early-life mortality, yet age-specific mortality before offspring independence and its associated costs have rarely been quantified. In this study, we modelled a...

Offspring are often produced in excess as insurance against stochastic events or unpredictable resources.
