Do females invest more into eggs when males sing more attractively? Postmating sexual selection strategies in a monogamous reed passerine
TLDR
The results suggest that female egg investment is related to male song performance in several aspects, but female investment patterns regarding various egg compounds are not simply correlated.
Negative impact of urban noise on sexual receptivity and clutch size in female domestic canaries
TLDR
It is suggested that noisy conditions may also affect avian communication in outdoor conditions, which may partly explain field reports on noise-dependent breeding success and reduced breeding densities at noisy sites.
Physically Challenging Song Traits, Male Quality, and Reproductive Success in House Wrens
TLDR
It is concluded that vocal deviation and trill consistency do not signal male quality in house wrens (Troglodytes aedon), a species with complex song structure.
Loss of Carotenoid Plumage Coloration Is Associated With Loss of Choice for Coloration in Domestic Canaries
TLDR
It is hypothesize that preference for brightly colored mates is ancestral in domestic canaries, but that strong artificial selection for white females to reproduce successfully with white males has eliminated the preference for color (along with color itself) in the white canaries.
Elevating perceived predation risk modifies the relationship between parental effort and song complexity in the song sparrow Melospiza melodia
TLDR
This study supports the hypothesis that increased costs of parental care associated with predation risk may induce relationships between sexually selected traits and parental behavior, which may increase the strength of sexual selection and suggests different aspects of song complexity may fulfill non-equivalent signaling roles.
Female mate choice, differential allocation and parent–offspring covariation in canaries
TLDR
The fact that parent–offspring covariation is consistently observed in canaries suggests that it is biologically relevant, but it requires further studies to elucidate its sensitivity to environmental variation.
Traffic noise affects embryo mortality and nestling growth rates in captive zebra finches.
TLDR
It is found that latency to breed and the size of successfully fledged clutches were consistent between groups, however success of initial nesting attempts was reduced by traffic noise, and that traffic noise may disproportionately affect chronically stressed individuals during reproduction.
Rapid Evolution of Bright Monochromatism in the Domestic Atlantic Canary (Serinus canaria)
TLDR
It is shown that domestic canaries evolved from dichromatism to monochromatism under strong selection for increased female coloration in <500 years and that red canaries, the hybrid lineage resulting from canary-siskin crosses, evolved from binary to dichromatic in <75 years.

Male Song Quality, Egg Size and Offspring Sex in Captive Canaries (Serinus canaria)
TLDR
It is found that under normal conditions larger eggs in a clutch are more likely to hatch male offspring and that females exposed to playback of more attractive songs produced larger eggs than those exposed to simpler songs containing no sexy syllables.
Strategic female reproductive investment in response to male attractiveness in birds
TLDR
It is shown that female birds generally invest more into reproduction when paired with attractive males, both in terms of egg size and number as well as food provisioning, and female allocation of immune-stimulants, anti-oxidants and androgens to the egg yolk was not consistently increased when mated to attractive males.
Egg investment is influenced by male attractiveness in the mallard
TLDR
It is shown that individual female mallard (Anas platyrhynchos) lay larger eggs after copulating with preferred males and smaller eggs afterCopulating with less preferred males, showing that differences between half-sibs cannot always be attributed to paternal or maternal genetic effects.
Directional female preference for an exaggerated male trait in canary (Serinusanaria) song
TLDR
It is suggested that female preference for vocal emissions, which simultaneously maximize these two parameters, could be a widespread pattern within songbirds.
Male song quality affects circulating but not yolk steroid concentrations in female canaries (Serinus canaria)
TLDR
It is shown that the level of circulating androgens and oestrogens of female canaries, as measured in faeces, varies with the quality of male song to which they are exposed, and this results in relation to the evolution of male signalling and maternal investment strategies.
Maternal investment in eggs is affected by male feet colour and breeding conditions in the blue-footed booby, Sula nebouxii
TLDR
It is found that blue-footed booby females probably favour brood reduction by decreasing egg quality and increasing size asymmetry between chicks when the breeding and the mate conditions are poor.
Sexual Selection for Aesthetic Traits in Species with Biparental Care

TLDR
It appears that attractive males are sometimes able to transcend a behavioral polygyny threshold by restricting investment in the offspring of one female sufficiently to invest in offspring of a second female, found in the tendency of attractive males to become simultaneous bigamists.
