Extra-Pair Paternity in the Wood Warbler (Phylloscopus sibilatrix) in Central Russia
AbstractExtra-pair paternity is widespread in passerine birds. The number of extra-pair young (EPY) varies among different species and populations of...

Extra-pair paternity in a species with frequent extra-pair courtship feedings, few extra-pair copulations, and male-biased parental care
Patterns of extra pair paternity (EPP) and intraspecific brood parasitism (IBP) were studied in a Whiskered Tern Chlidonias hybrida population...

Male aggressiveness during the female fertile phase in relation to extra-pair paternity, plumage ornaments and female traits
In many bird species, physical aggression between males become more frequent during the female’s fertile period, as female encounters with extra-pair...

High level of extra-pair paternity in the socially monogamous Marsh Tits (Poecile palustris)
BackgroundExtra-pair copulation behavior has been widely studied among socially monogamous birds. Many species revealed high rates of extra-pair...

Do female bluethroats without extra-pair offspring have more MHC-compatible social mates?
AbstractGenes of the major histocompatibility complex (MHC) are crucial for adaptive immunity in jawed vertebrates, and theory predicts that there...

Emergence of games from ecological trade-offs: longevity changes strategies for extra-pair mating in birds
AbstractEach member of a breeding pair benefits if the other does more of the parental investment, so there is scope for behaviours that can be...

Mobbing for matings: dynamics, plumage correlates, and fitness impacts of conspicuous group extra-pair behaviors in the lark bunting
The widespread occurrence of extra-pair paternity (EPP) in birds adds rich complexity to our understanding of sexual selection and mating system...

Extra-pair paternity and antiparasitic defence
BackgroundExtra-pair paternity (EPP) in birds provides benefits in terms of more offspring, and characteristics for maintenance of this behaviour...

Neither paternity loss nor perceived threat of cuckoldry affects male nestling provisioning in grass wrens
AbstractExtra-pair paternity (EPP) is frequent in socially monogamous birds with biparental care. However, males should avoid providing care to...

From self-interest to cooperation: extra-pair mating as a driver of relaxed territorial aggression in social neighbourhoods
In socially monogamous bird species, males and females tailor their reproductive strategies to that of the other. Interactions are complex, and have...

Extra-pair paternity and intraspecific brood parasitism in the Gentoo Penguin (Pygoscelis papua) on Elephant Island, Antarctica
Recent studies have shown that many species of apparently monogamous birds engage in extra-pair copulation (EPC). Penguins have intense shared...

Molecular evidence of extra-pair paternity and intraspecific brood parasitism by the Magellanic Penguin (Spheniscus magellanicus)
Molecular studies have shown that, although most avian species are socially monogamous, they can exhibit different reproductive strategies, such as...

Extra-pair paternity and sperm length variation in the socially monogamous Fieldfare Turdus pilaris
Basic knowledge about the genetic mating system is lacking for the great majority of the approximately 10,000 extant bird species. Filling this...

An experimental increase in female mass during the fertile phase leads to higher levels of extra-pair paternity in pied flycatchers Ficedula hypoleuca
AbstractFemale mass in most altricial birds reaches its maximum during breeding at egg laying, which coincides temporally with the fertile phase when...

Elevation affects extra-pair paternity but not a sexually selected plumage trait in dark-eyed juncos
AbstractDifferences in environmental conditions are expected to generate distinct selective pressures favoring different phenotypes. For example,...
-
Extra-pair paternity patterns in European barn swallows Hirundo rustica are best explained by male and female age rather than male ornamentation
AbstractAdaptive explanations for the evolution of extra-pair paternity (EPP) in birds often assume cuckolding males to be better-ornamented than...
-
Male condition and group heterogeneity predict extra-group paternity in a Neotropical bat
AbstractExtra-group paternity, in which offspring are sired by a male outside the breeding group, may alter the distribution of reproductive success...

Seasonal variation in cuckoldry rates in the socially monogamous cichlid fish Variabilichromis moorii
Mating patterns in animal populations can respond to environmental conditions and consequently vary across time. To examine this variation in nature,...

Opportunity is not everything: genetic monogamy and limited brood parasitism in a colonial woodpecker
AbstractAvian social and genetic mating systems are influenced by parental care roles as well as by reproductive opportunities. Alternative...

Understanding Variation in Extra-Pair Paternity in Birds: A Focus on Neotropical Birds
Variation in life-history traits has long captivated ecologists and evolutionary biologists. Classical studies of life-history theory identify...
