Extra-pair paternity (EPP) is often linked to male age in socially monogamous vertebrates, i.e. older males are more likely to gain EPP and less likely to be cuckolded. However, whether this occurs be
Incubation prior to clutch completion may be adaptive if it maintains egg viability by inhibiting eggshell microbial growth, thus reducing the likelihood that the embryo becomes infected. To test this
1. One hypothesis explaining extra-pair reproduction is that socially monogamous females mate with extra-pair males to adjust the coefficient of inbreeding (f) of extra-pair offspring (EPO) relative t
