| Summary: | 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 ... : white_tailed_eagle_femaleThis dataset includes all breeding attempts by known age female white-tailed eagles between 3 – 26 years old and the associated information of the partner if known. FemaleID = individual code for female identity MaleID = individual code for male identity OriginF = Origin of female OriginM = Origin of male (if known) Origin categories: R1 = release phase 1, R2 = release phase 2, W= wild bred Territory = individual code for breeding territory Year = year of breeding attempt FAge = The age of the female Mage = The age of the male (if known) Fexp = The number of breeding year / experience of the female Mexp = The number of breeding year / experience of the male (if known) Success = 0/1 if any chicks were fledged or not Fledged = 0/1/2 the number of chicks fledgedwhite_tailed_eagle_maleThis dataset includes all breeding attempts by known age male white-tailed eagles between 3 – 26 years old and the associated information of the partner if known.
