DOI: 10.1007/s00265-017-2329-x
Abstract: Several studies have suggested that vegetation structural complexity can influence the frequency of extra-pair copulations, especially by reducing mating-guarding efficiency. Here we investigate if habitat structural complexity affects broad patterns of extra-pair paternity (EPP) and… read more here.

An experimental increase in female mass during the fertile phase leads to higher levels of extra-pair paternity in pied flycatchers Ficedula hypoleuca

Abstract: Female mass in most altricial birds reaches its maximum during breeding at egg laying, which coincides temporally with the fertile phase when extra-pair paternity (EPP) is determined. Higher mass at laying may have two different… read more here.

DOI: 10.1073/pnas.2112004119
Abstract: Significance In many monogamous species, a substantial proportion of offspring is sired by other males than the one providing care at the nest. Although females often solicit extra-pair mating, the benefits of extra-pair copulations to… read more here.

DOI: 10.1098/rsbl.2019.0360
Abstract: There is no consensus yet on the reasons why females engage in extra-pair copulations (EPCs). In some species, females have been shown to accrue some indirect benefits, but these effects are not consistent across species… read more here.

Abstract: Extra-pair paternity (EPP) benefits to improve the reproductive success via extra-pair fertilizations without the costs of parental care in males and through improved offspring quality with additional food and parental care in females among species… read more here.

Extra‐pair paternity and sexual dimorphism in birds
Sign Up to like & getrecommendations! Published in 2023 at "Journal of Evolutionary Biology"
DOI: 10.1111/jeb.14172
Abstract: Differences in the strength of sexual selection between males and females can lead to sexual dimorphism. Extra‐pair paternity (EPP) can increase the variance in male reproductive success and hence the opportunity for sexual selection. Previous… read more here.

Abstract: Roughly 90% of socially monogamous bird species exhibit some degree of extra-pair paternity (EPP), although the extent and the underlying mechanisms vary among species. We analyzed spatial and demographic patterns of EPP over a 6… read more here.

DOI: 10.2989/00306525.2017.1304461
Abstract: The Cape Vulture Gyps coprotheres is an Endangered colonial cliff-nesting species that is typically cited as monogamous. Observations of wild Cape Vulture colonies note extra-pair breeding activities but homosexual activity has never been confirmed. Observations… read more here.
