Dunn & Lifjeld (1994) indicate that in our original both partners was known and that of these 24 analysis (Birkhead & Marller 1992) of the relation- involved the senior female of the group. Of these ship between extra-pair copulation and extra-pair 24. 15 (62.5%) involved the senior male, but nine paternity in birds some of the data we used were (37.5%) involved a helper male. We should in fact inappropriate. Specifically, they state that data for have used the latter value. However, a more… Expand
Extrapair Copulations Predict Extrapair Fertilizations in the American Crow
TLDR
For each group of nesting crows, the proportion of extrapair young in a brood was higher when EPC attempts were observed in the group that year, suggesting that EPCs were attempted by multiple males with certain females in certain years. Expand
Extra-pair fertilizations in the Sedge Warbler
TLDR
The results are consistent with the hypotheses that females participating in EPF are seeking genetic benefits to their offspring, but cannot exclude the alternative explanation that attractive males are more efficient in forcing females to accept EPF. Expand
Extra-pair copulation and paternity defense in the hihi (or stitchbird) Notiomystis cincta
TLDR
Paired males attempted to defend their paternity by defending an area around the nest site, by territorial calling and displacing intruding males, and this variation mirrored closely the variation in the percentage of extra- pair paternity. Expand
High levels of extra-pair paternity in Superb Fairy-wrens in South Australia despite low frequency of auxiliary males
TLDR
This work studied group size and extra-pair paternity in South Australia where, unlike other study sites, auxiliary males were relatively uncommon: 16% of nests had one auxiliary male compared to 37–80% with at least one auxiliary per nest in other studies. Expand
Copulations and Mate Guarding of the Chinese Egret
TLDR
There was an asynchronous fading in bill color between sexes after laying, which probably accounted for the male's preference for an egg-laying female as extra-pair mate. Expand
Extra pair copulation in the Eurasian beaver (Castor fiber)
TLDR
Based on the genetic data it appears that the Eurasian beaver is a strict genetically monogamous species, in concordance with the observational data. Expand
Experimental analysis of sperm competition mechanisms in a wild bird population
TLDR
A field study of collared flycatchers showed that female collaredFlycatchers preferentially engaged in extra-pair copulations when mated to an unattractive male with a small white forehead patch, suggesting a possible behavioral mechanism for female control of sperm competition. Expand
Social mating systems and extrapair fertilizations in passerine birds
TLDR
It is hypothesized that in socially polygynous species, there is less incentive for females and males to pursue extrapair matings and females incur higher costs for sexual infidelity than in socially monogamous species. Expand
Do Women Have Evolved Adaptation for Extra-Pair Copulation?
Do women have special-purpose evolved adaptation that functions in pursuing copulations with men other than the main romantic partner, just as they have specialized adaptation for seeing color,Expand
EXTRAPAIR PATERNITY AND THE EFFECTIVE SIZE OF SOCIALLY MONOGAMOUS POPULATIONS

TLDR
A demographic model is used to gauge the potential magnitude of errors in the effect on (variance) N, of a previously ignored demographic complexity: extrapair fertilizations in socially monogamous avian populations. Expand

Extra-Pair Copulations and Mate Guarding in the Polyterritorial Pied Flycatcher, Ficedula Hypoleuca
TLDR
It is most likely that male reproductive strategies are not maintained as a frequency-dependent mixed ESS with equal pay-offs for all paired males, Instead, male strategies are conditional on phenotype and breeding circumstances. Expand
Paternal investment inversely related to degree of extra-pair paternity in the reed bunting
TLDR
An exceptionally high proportion of extra-pair paternity is found in a wild population of reed buntings using single-locus DNA fingerprinting and it is proposed that males can assess their likelihood of paternity and adjust their nestling provisioning rates accordingly. Expand
Extra-pair copulations in a predominantly monogamous bird: observations of behaviour
TLDR
The mating behaviour of indigo buntings, Passerina cyanea was studied and the possible role of nesting density, mate guarding, synchrony of breeding, male parental care and polygyny on the rate of EPCs is examined. Expand
Extra-Pair Paternity in the European Starling: The Effect of Polygyny
TLDR
It is suggested that the relative ease by which female Starlings can be mate-guarded, the fact that mate-attraction and mate-GUarding do not have to be exclusive activities and the high within pair copulation frequency in Starlings may keep the degree of extra-pair paternity low. Expand
Extra-pair paternity results from female preference for high-quality males in the blue tit
TLDR
Evidence is presented that such an asymmetry is indeed caused by female behaviour, and that 'attractive' males do not suffer lost paternity, survive better and recruit more young, and the results support the genetic quality hypothesis. Expand
Extra‐pair paternity in the shag, Phalacrocorax aristotelis as determined by DNA fingerprinting
TLDR
The frequency of chicks resulting from extra-pair copulation in the shag, Phalacrocorax aristotelis, was measured by DNA fingerprinting and it was found that 18% of the chicks had extra- Pair paternity, and one chick was not the offspring of either member of the pair, implying either a polygynous male whose second female was fertilized by another male or adoption. Expand
Frequent copulation as a method of paternity assurance in the northern fulmar
TLDR
This study combines a complete record of copulation behaviour with paternity determined by DNA finger-printing in order to establish whether extra- Pair copulations result in extra-pair paternity and to investigate how the fertilizing male achieves paternity. Expand
Helpers liberate female fairy-wrens from constraints on extra-pair mate choice
TLDR
It is suggested that females allow males in pairs more paternity to ensure their assistance with parental care, and that mating options for females in other species with female control of fertilization may also reflect a trade-off between acquiring the genes of high-quality males for their offspring and parental care of those offspring. Expand
No evidence for illegitimate young in monogamous and polygynous warblers
TLDR
The use of a bird minisatellite DNA probe is described in assigning paternity in natural populaá-tions of the monogamous willow warbler Phylloscopus trochilus and of the polygynous wood warblerPhylloscopeopus sibilatrix, implying that extra-pair copulations have little or no genetic impact. Expand
Extrapair Fertilization in Monogamous Bull-Headed Shrikes Revealed by DNA Fingerprinting
TLDR
Parentage in a wild population of the Bull-headed Shrike by DNA fingerprinting is analyzed, showing that copulation frequency is not necessarily a good measure of reproductive success even in monogamous birds where no extrapair copulations are observed. Expand
