Replication Data for: Mate-switching is not associated with offspring fitness in a socially monogamous bird

Offspring fitness was characterised using measures of condition at the juvenile stage (telomere length, body mass, haematocrit) and long-term components (lifespan, lifetime reproductive success).

Data was gathered from the long-term Seychelles warbler database and the pedigree available for the Seychelles warbler population on Cousin Island, Seychelles between 1997 to 2021 over all breeding seasons that were monitored. There are multiple datasets, all including a separate metadata file describing all variables used, with the same name as the file including "_metadata". All analyses and figures can be reproduced using the R-scripts using the datafiles supplied.
