Females of many socially monogamous bird species accept or even actively seek copulations outside the social pair bond. It has been shown that females profit from extrapair fertilization by increased offspring quality, but extrapair mating may also induce costs to females. We measured parental food provisioning and paternity in the reed bunting, Emberiza schoeniclus, a species with biparental...

Elaborate birdsong is thought to have evolved under sexual selection. Extrapair mating can enforce sexual selection and thus the selection of song traits. We investigated song rate and song diversity, two song traits previously shown to be under sexual selection, in relation to paternity success in the reed bunting, Emberiza schoeniclus, a species with high levels of extrapair paternity. We...
