While studies of mate choice based on male color pattern are ubiquitous, studies of mate choice based on ornamental color traits in sexually monomorphic species are less common. We conducted manipulative field experiments on two color ornaments of king penguins (Aptenodytes patagonicus), the size of auricular patches of orange feathers and degree of UV reflectance from beak spots, to determine how the degree of ornamentation influenced pairing rate. In a reduction of auricular patch size…

Sexual Selection on a Coloured Ornament in King Penguins

TLDR
The previously documented sex-similar size of yellow-orange ear patches in the king penguin, Aptenodytes patagonicus, is examined to test whether the size of the coloured ear patch was influenced by sexual selection for couples that had recently paired.

Color ornaments and territory position in king penguins

Variation of mutual colour ornaments of king penguins in response to winter resource availability

TLDR
The results suggest that the expression of sexual traits may substantially vary under different environmental conditions, a predication of some models of mate choice and sexual selection.

Mutually honest? Physiological ‘qualities’ signalled by colour ornaments in monomorphic king penguins

TLDR
Over an exhaustive set of physiological variables, several suggestive patterns indicated the conveyance of honest information about mate quality in this monomorphic species, however, sex-specific patterns suggested that monomorphic ornaments may signal different information concerning body mass and oxidative balance of males and females, at least in king penguins.

Male-Biased Mate Competition in King Penguin Trio Parades

TLDR
It is concluded that intrasexual selection in this colony follows the typical pattern of mate competition observed in species in which sexual dimorphisms and OSR are male biased, and the ultraviolet difference within the framework of the king penguins' colour perception is discussed.

Mate Choice in a Sexually Dimorphic Marine Bird, the Great Frigatebird (Fregata minor)

TLDR
This dissertation investigated several aspects of sexual selection and the evolution of female mating preferences and male ornaments in the great frigatebird (Fregata minor), finding no evidence forFemale mating preferences based on visual or auditory display traits associated with male ornamentation, however, there was a significant disassortative mating pattern amongst mated pairs compared to random pairings based on MHC genotypes.

Sexually monomorphic wing pigmentation pattern does not contribute to mate choice in Drosophila guttifera

TLDR
This work examined whether the sexually monomorphic polka-dotted pattern on wings of Drosophila guttifera contributes to mate choice, and found that presence of wings influenced mate choice in both sexes.

Assortative mating by multiple skin color traits in a seabird with cryptic sexual dichromatism

TLDR
It is suggested that such a mating pattern may result from a scenario where both sexes choose mates based on traits that convey reliable information of individual quality, as well as a condition-dependence of plasma androgen levels.

Females Choose Mates Based on Genetic Relatedness in a Small Dasyurid Marsupial, the Agile Antechinus (Antechinus agilis)

TLDR
The results show that genetic relatedness between mates has a significant influence on mate choice, breeding and siring success in the agile antechinus.

Sex identification in King Penguins Aptenodytes patagonicus through morphological and acoustic cues

TLDR
It is shown that King Penguins can be sexed based on a single morphological measurement of the beak with an accuracy of 79% and a sex-specific syntax in adult King Penguin calls that provided a 100% accurate method to distinguish between the sexes in the study population.

Experiments on colour ornaments and mate choice in king penguins

Female choice selects for male sexual tail ornaments in the monogamous swallow

TLDR
In the monogamous swallow, Hirundo rustica, males with experimentally elpngated tail ornaments obtain mates more quickly than males with shorter tails, and enjoy increased reproductive output in one breeding season, suggesting male sexual ornament may also be maintained by female mate choice in monogamous species.

Degree of mutual ornamentation in birds is related to divorce rate

  • Biology
    Proceedings of the Royal Society of London. Series B: Biological Sciences
  • 2003
TLDR
The results show a significant positive association between the degree of mutual ornamentation and divorce rate, and it is argued that these results are compatible with a process of mutual sexual selection, in which both sexes compete for access to mates.

Correlations between ultraviolet coloration, overwinter survival and offspring sex ratio in the blue tit

TLDR
The correlations that are found are consistent with models of adaptive sex ratio adjustment in response to mate quality, but careful experimental work is required to provide tests of the assumptions of these models, and should be a priority for future work.

Is territory defence related to plumage ornaments in the king penguin Aptenodytes patagonicus

TLDR
The results suggest that the size of the auricular patch in king penguins may be a reliable signal allowing individuals to evaluate the quality of mates or competitors in terms of aggressiveness, adding to the growing evidence that the evolution of sexually monomorphic ornaments may stem from mutual sexual selection.

Mouth coloration of nestlings covaries with offspring quality and influences parental feeding behavior

TLDR
The hypothesis that mouth coloration acts as a signal of nestling condition in the barn swallow Hirundo rustica is supported and it is shown that UV flange coloration influences parental decisions regarding food allocation.

Male preference for female foot colour in the socially monogamous blue-footed booby, Sula nebouxii

Sexual ornament size and breeding performance in female and male European Shags Phalacrocorax aristotelis

TLDR
It is suggested that ornament size is related to state in European Shags, and thus may be involved in mate choice in both sexes, and individuals were found to be paired assortatively with respect to crest size.

FEMALE MATE CHOICE IN RELATION TO STRUCTURAL PLUMAGE COLORATION IN BLUE GROSBEAKS

TLDR
The intensity of blue coloration of male Blue Grosbeaks appears not to function as a criterion in female mate choice, and the intensidad of coloración azul of Passerina caerulea no parece servir como criterio selectivo in the elección of pareja.
