Abstract

In most passerine birds, individuals attempt to maximize their fitness by providing parental care while also mating outside their pair bond. A sex-specific trade-off between these two behaviours is predicted to occur, as the fitness benefits of extra-pair mating differ between the sexes. We use nest observations and parentage analysis to reveal a negative association between male care and the incidence of extra-pair paternity across three species of penduline tit (Remizidae). This provides evidence of a trade-off between these two behaviours, possibly due to the devaluing of paternal care by extra-pair offspring.
