I am studying a species of warbler (bird) that builds nests in mesquite trees, and I notice that some of the older birds build larger nests. I hypothesize that the population is age structured, with older birds having a higher reproductive rate. Which of the options below is a specific prediction that would test my hypothesis?
1) Older birds will raise more chicks in a year than younger birds.
2) Older birds will raise fewer chicks in a year than younger birds.
