Supplementary material 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...
