Table S1. A literature review of published studies thatused wild bird populations to directly compare the survival of extra-pair young (EPY) and within-pair young (WPY). Data presented include:sample size of broods and/or chicks (n), whether the difference in survival between EPY and WPY at various life-history stages was statistically significant and if so the direction of the difference (n/sindicates instances where the difference in survival was not significant),whether the analyses included a half-sibling survival comparison, and whether tests for extra-pair status by sex or extra-pair status by environment interactionswere explicitly reported. Whenthe survival differenceamongEPY and WPY from mixed paternity broods (i.e., those known to contain ≥1EPY and ≥1 WPY) was reported in addition to the difference amongall sampled EPY and WPY, only the formerresults are presented. This review highlights the lack of studies that have tested either for differences in long-term survival (lifespan) between EPY and WPY half-siblings or for sex-and environment-specific differences in relative survival of EPY and WPY.
