Abstract Genetic parentage was examined in the territorial and predominantly monogamous bluethroat, by means of multilocus DNA fingerprinting. Thirty-five per cent (11/31) of nests contained one or more offspring sired by extra-pair males, in total 20% (30/150) of all offspring. The frequency of extra-pair paternity was similar in the two study years. All offspring were genetically related to their putative mother, thus no evidence for intraspecific brood parasitism was found. Extra-pair… 
Extra-pair paternity and mate-guarding behaviour in the brown thornbill
TLDR
It is speculated that the relationship between male size/age and extra-pair paternity in brown thornbill may arise because female thornbills prefer large males as mates but are unable to express this preference as easily when paired to older males.
High frequency of extra-pair fertilisations in the moustached warbler, a songbird with a variable breeding system
TLDR
The results suggest that female moustached warblers obtain direct benefits from extra-pair copulations, however, a skewed fertilisation pattern implies that genetic compatibility between mates and copulation partners may also influence female extra- Pair behaviour in this species.
Genetic evidence for mixed parentage in nests of the emu (Dromaius novaehollandiae)
TLDR
A high frequency of extra-pair fertilisations and resultant cuckoldry in a predominantly socially monogamous bird and patterns of descent that differ greatly from those implied by social monogamy are revealed.
Is female promiscuity constrained by the presence of her social mate? An experiment with bluethroats Luscinia svecica
TLDR
The results show that pair males exert constraints on the frequency of extra-pair paternity by being present during the period of peak fertility, which could be a direct effect of their mate guarding effort and/or due to an advantage in sperm competition for pair males.
Nestling sex ratios in a population of Bluethroats Luscinia svecica inferred from AFLP™ analysis
TLDR
Sex determination in the Bluethroat seems to match the classical Mendelian model of a 1:1 sex ratio and cannot explain the biased sex ratio towards juvenile females found at the wintering site.
High frequency of extra-pair paternity in a dense and synchronous population of Willow Warblers Phylloscopus trochilus
Genetic parentage was studied in a Norwegian, sub-alpine population of Willow Warblers Phylloscopus trochilus by means of multilocus DNA fingerprinting. We found that 33% (36/109) of the offspring
Ecological constraints on extra-pair paternity in the bluethroat
TLDR
The results indicate that ecological conditions have no influence on whether or not a brood will contain extra-pair offspring, but when EPP does occur, its frequency is influenced by air temperature.
MALE CHARACTERISTICS AND FERTILISATION SUCCESS IN BLUETHROATS
TLDR
The results indicate that experiments where traits are manipulated outside the natural range should be interpreted with caution, and illustrate the importance of a dual approach (experimental and correlative) in studies of sexual selection in the wild.
Genetic Parentage and Variable Social Structure in Breeding Southern Lapwings
TLDR
A flexible social and genetic mating system in Southern Lapwings is demonstrated, with one chick had a DNA fingerprint with four novel bands but shared a high proportion of bands with both primary pair members of its group.
Age-Related Variation in Mate-Guarding Intensity in the Bluethroat (Luscinia s. svecica)
Female extra-pair copulations (EPCs) have selected for male paternity guarding strategies in many bird species. In the bluethroat, Luscinia s. svecica, males guard their mates closely during the last

Parental care and mating behaviour of polyandrous dunnocks Prunella modularis related to paternity by DNA fingerprinting
TLDR
It is shown that in the dunnock Prunella modularis, a small passerine bird with a variable mating system, males do not discriminate between their own young and those of another male in multiply-sired broods, which is a good predictor of paternity.
Extra-pair paternity and intraspecific brood parasitism in the European starling, Sturnus vulgaris: evidence from DNA fingerprinting
TLDR
There was no significant evidence that polygynous males suffer from a higher risk of being cuckolded than monogamous males and indeed only one case was detected by DNA fingerprinting.

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.
Extramarital and Pair Copulations in the Cattle Egret
TLDR
The behavior accompanying both pair copulations and ECs is described, quantitative data on the temporal variation in the frequency of ECs are analyzed, and underlying causal factors are considered.
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.
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.

Cuckoldry through stored sperm in the sequentially polyandrous spotted sandpiper
TLDR
It is reported that males pairing early in the season cuckold their females' later mates by means of stored sperm, and early-pairing males not only have greater confidence of paternity, but also increase their reproductive success by fertilizing a proportion of eggs laid for, and incubated by, their Females' subsequent mates, in addition to those they incubate themselves.
