Data from: Sex-specific patterns of reproductive senescence in a long-lived reintroduced raptor
1) For many species there is evidence that breeding performance changes as an individual ages. In iteroparous species, breeding performance often increases through early-life and is expected to level out or even decline (senesce) later in life. Furthermore, an individual’s sex and conditions experie...

1) For many species there is evidence that breeding performance changes as an individual ages. In iteroparous species, breeding performance often increases through early-life and is expected to level out or even decline (senesce) later in life. Furthermore, an individual’s sex and conditions experienced in early-life can affect breeding performance and how this changes with age. 2) Long-term monitoring of individuals from reintroduced populations can provide unique opportunities to explore age-related trends in breeding performance that might otherwise be logistically challenging. 3) We used a unique dataset from a reintroduced population of white-tailed eagles Haliaeetus albicilla in Scotland, which has been intensively monitored since their initial reintroduction in 1975, to study age- and sex-specific trends in two measures of breeding performance. This monitoring provided data on breeding performance of known individuals ranging in age from 3 to 26 years old. We also explored changes in breeding performance in relation to early-life experience (i.e. whether they were released or fledged in the wild). 4) Breeding performance increased with age in early-life in a similar manner for both sexes.
