The “sexy son” hypothesis suggests that females obtain future fitness benefits from mating with polygynous males through the inheritance by their sons of traits contributing to mating success. We tested this hypothesis in the facultatively polygynous European starling (Sturnus vulgaris) in two ways. We first compared sons of monogynous and polygynous free-living males for their abilities in nest site acquisition and female-directed behaviors in controlled aviary tests. We then investigated eggs… 

A role for female ornamentation in the facultatively polygynous mating system of collared flycatchers

A subtle role for female ornamentation at polygynous mating is suggested, and patterns in quality-indicating female traits may contribute to the explanation of differences in reproductive success among females of different mating status.

Hatchling sex ratio and female mating status in the great reed warbler, Acrocephalus arundinaceus (Aves, Passeriformes): further evidence for offspring sex ratio manipulation

Examination of hatchling sex ratio variation in relation to female mating status in a local population of facultatively polygynous great reed warblers Acrocephalus arundinaceus in Central Europe found that monogamous and primary females had a higher proportion of sons in their broods than secondary females.

Laying date and polygyny as determinants of annual reproductive success in male collared flycatchers (Ficedula albicollis): a long-term study

The findings support the importance of breeding date and suggest stabilizing selection on it in the long term, and show that polygyny is not always advantageous for males, and its fitness pay-off may depend on environmental quality.

Androgen-dependent maternal effects on offspring fitness in zebra finches

The benefits of biasing sex ratio towards males by increasing androgen level in the yolk may be limited due to negative effects on male offspring performance early in life.

Lifetime offspring production in relation to breeding lifespan, attractiveness, and mating status in male collared flycatchers

The results demonstrate that the relationship between longevity and LRS is not explained by the higher number of reproductive attempts when living longer, and question the adaptive value of polygyny in this population of flycatchers.

Maternal yolk androgens in European starlings: affected by social environment or individual traits of the mother?

Within-female yolk androgen levels were highly consistent over two consecutive years even though females were breeding in opposite breeding densities during each year, suggesting that individual characteristics are important determinants of variation in maternal androgen allocation in addition to potential effects of environmental conditions.

Evolutionary consequences and fitness correlates of extra-pair mating in the tūī, Prosthemadera novaeseelandiae

The influence of sexual selection on the evolution of reproductive behaviours and male secondary sexual characters is investigated in the New Zealand tūī, Prosthemadera novaeseelandiae to examine correlates and fitness consequences of female within-pair and extra-pair mate choice.

Sexual selection and the function of a melanin-based plumage ornament in polygamous penduline tits

It is concluded that there is either no directional selection on male mask size or males with larger masks receive indirect, long-term benefits, as nestling survival decreased with mask size.

Nest-site defence aggression during courtship does not predict nestling provisioning in male collared flycatchers

It is found that territorial aggression did not correlate with nestling feeding rate, which suggests that nest-site defence behaviour in the beginning of the breeding season does not carry information for females about what to expect from potential mates in terms of parental care.

Sexual selection and the function of a melanin-based plumage ornament in polygamous penduline tits Remiz pendulinus

The study revealed that mask size of males is more likely an honest signal used by females in their mate choice decisions than a trait involved in male–male competition, and concluded that there is either no directional selection on male mask size or males with larger masks receive indirect, long-term benefits.



Paternal care in the European starling, Sturnus vulgaris: nestling provisioning

The results show that both the “defence of male parental investment model” and the ‘asynchronous settlement model’ have explanatory power, but that their validity depends on the potential length of the breeding season.


The higher nestling mortality rates in polygynous broods without male help during the early and mid-nestling stages suggest that unaided females cannot compensate fully for the reduction in male assistance, that male starlings can improve female fledging success by assisting in feeding nestlings, and that the reduced reproductive success of secondary females is directly linked to the strongly reduced male assistance in feeding.

Polygyny in the european starling: effect on female reproductive success

Intrasexual competition among polygynously mated female starlings (Sturnus vulgaris)

In southern Sweden, the starling (Sturnus vulgaris) has a variable mating system with some males mating monogamously and others attracting several females: monogamous and primary females laid larger clutches and fledged more and heavier young than secondary females.

An experiment in which females were given choices between two adjacent territories, one owned by an unmated male without any over–water nesting sites and the other by an already–mated male with over-water sites, demonstrated that superior territory quality can reverse preferences based on mating status and supporting the polygyny threshold model as the explanation for polygyNY in this population.

Polygyny in the blue tit: unbalanced sex ratio and female aggression restrict mate choice

In this study, thepolygyny-threshold model could not be used to explain polygyny, since one of its basic assumptions, that females are free to settle where they choose, was violated, and it is argued that the model can work on a larger scale.

Alternative Models of Territorial Polygyny in Birds

It is clear that no one model explains territorial polygyny in all species with this system, and general methods for testing the models are outlined, which cannot completely discriminate among the models for even the best-studied species.

Evolution of Female Choice and Male Parental Investment in Polygynous Species: The Demise of the "Sexy Son"

These models address the "sexy son" hypothesis of Weatherhead and Robertson (1979), which contends that selection can create an equilibrium at which females on the average mate with certain attractive types of males that give them inferior material resources and therefore decrease the females' immediate reproductive success.

Extra-Pair Paternity in the European Starling: The Effect of Polygyny

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.
