Evolution of female carotenoid coloration by sexual constraint in Carduelis finches

It is suggested that most evolution of female carotenoid coloration was male-driven and, when adaptive, may not be an adaptation stricto sensu.

Wing Colour Properties do not Reflect Male Condition in the American Rubyspot (Hetaerina americana)

These and previous results suggest that only spot size but not the spot characteristics the authors measured here, is sexually selected in males of this species at least in terms of pre-copulatory male–male competition.

Sexual dimorphism and directional sexual selection on aposematic signals in a poison frog

The results show that sexual selection should not be ignored in studies of aposematic evolution and document sexual dimorphism in vertebrate warning coloration.

Is bill colouration in wild male Blackbirds (Turdus merula) related to biochemistry parameters and parasitism?

The results suggest that certain physiological constraints—rather than parasite infection—are the main cause of variability in the colouration of male Blackbird bills.

Speciational Evolution of Coloration in the Genus Carduelis

It is concluded that in the genus Carduelis the evolutionary lability of ornaments influences speciation more than the strength of sexual selection, and ornament lability should be considered as a possible causal factor in studies comparing cladogenesis among taxa.

Similar preferences for ornamentation in opposite‐ and same‐sex choice experiments

It is shown that preferences for ornamentation in the opposite‐sex also extend to same‐sex interactions, and similar preferences in sexual and nonsexual associations may be widespread in nature, either as social adaptations or as by‐product of mate preferences.

Phylogeny and evolution of sexually selected tail ornamentation in widowbirds and bishops (Euplectes spp.)

The results suggest that the nuptial tail of Euplectes is a derived and phylogenetically conserved ornamental trait that, once gained, shows directional evolution in its expression, and supports an early origin and strong retention of directional female mate choice in widowbirds and bishops.

8. Colorful Phenotypes of Colorless Genotypes: Toward a New Evolutionary Synthesis of Color Displays

Few animal taxa rival birds in richness and diversity of color displays, and few traits have stimulated more studies of natural and sexual selection than animal coloration. Although we have some

Plastic sexual ornaments: Assessing temperature effects on color metrics in a color-changing reptile

It is shown that the rate of change in saturation between two temperatures is inconsistent across individuals, increasing at a higher rate in individuals with higher baseline saturation at lower temperatures, and the relative color rank of individuals in a population varies with the temperature standardized by the investigator, but more so for some metrics than others.



Female house finches prefer colourful males: sexual selection for a condition-dependent trait

Plumage redness predicts breeding onset and reproductive success in the House Finch: A validation of Darwin's theory

It is shown that, by initiating breeding earlier in the season, brightly colored males fledge more offspring in a season than do drab males, and contributes to sexual selection for male plumage ornamentation in this species.

Correlated Evolution of Female Mating Preferences and Male Color Patterns in the Guppy Poecilia reticulata

Male traits and female preferences appear to be evolving in parallel in guppy populations, and in a comparison of seven populations, the degree offemale preference based on orange is correlated with the population average orange area.

Pairing success relative to male plumage redness and pigment symmetry in the house finch: temporal and geographic constancy

Observations support the idea that expression of carotenoid-based plumage coloration by males is a persistent and widespread criterion in female mate choice in the house finch.

Plumage coloration is a sexually selected indicator of male quality

Results of field studies indicate that females prefer to mate with colourful males and that plumage brightness correlates with a male's capactity for parental care and perhaps its genotypic quality.

High Parasite Load in House Finches (Carpodacus mexicanus) is Correlated with Reduced Expression of a Sexually Selected Trait

This is the first study to monitor (via mark-recapture) the long-term effects of parasites on color and growth of plumage in individual birds and demonstrates that both ectoparasitic feather mite infestations and endoparAsitic avian pox viral infections during molt are correlated with poor physiological condition and reduced development of bright male plumage during the same molt period, thus supporting good genes models.

Plumage colour signals nutritional condition in the house finch

Observations provide support for the hypothesis that carotenoid-based plumage coloration is an indicator of nutritional condition during moult, which may arise from differences among individuals in either their foraging ability or their health.

Carotenoid-based ornamentation and status signaling in the house finch

It is suggested that carotenoid-based coloration may function only in mate choice in this species, and it may be retained throughout the year either because time constraints preclude a second plumage molt or because it aids in pair formation that begins in late winter.

“A Taste for the Beautiful”: Latent Aesthetic Mate Preferences for White Crests in Two Species of Australian Grassfinches

Experimental evidence is presented that two avian species from a lineage devoid of crested species have mate preferences for opposite sex conspecifics wearing artificial white crests, providing additional powerful evidence for highly structured aesthetic mate preferences in estrildine finches.

Evolution of sexual dichromatism: contribution of carotenoid- versus melanin-based coloration

The results supported the hypothesis that melanin-based and carotenoid-based coloration have fundamentally different signal content and suggest that combining melanin -based andCarotenoids- based coloration in comparative analyses is not appropriate.
