The evolution of multiple sexual traits remains controversial and poorly understood in evolutionary biology. In many bird species, males exhibit complex courtships involving feather ornaments and behavioral display. Multiple traits may convey information on the genetic and phenotypic quality of males. In particular, fixed characters, such as feather ornaments (produced once a year during the annual molt in many bird species) might convey information about past male condition (at the time of… Expand

Figures from this paper

Courtship and male ornaments as honest indicators of immune function
TLDR
The results indicate that females may be able to use static sexual signalling traits to examine a male's overall health, but females do not appear to discriminate against males who are actively infected, even though there is a direct cost to the female via the transfer of male infection. Expand
Male health status, signalled by courtship display, reveals ejaculate quality and hatching success in a lekking species.
TLDR
By assessing male courtship display, females may gain insight into the current phenotypic/genetic quality of mates and gather fitness benefits in terms of reproductive success, and show that early reproductive failure was increased when females were artificially inseminated with semen from immune-activated males. Expand
Parasites and health affect multiple sexual signals in male common wall lizards, Podarcis muralis
TLDR
This work examined whether ventral coloration and chemicals in femoral gland secretions of male common wall lizards, Podarcis muralis, are affected by their health state (blood-parasite load and cell-mediated immune response) and indicated that less parasitized lizards had brighter and more yellowish ventral Coloration and femoral secretions with higher proportions of two esters of octadecenoic acid. Expand
Sex-specific signalling of individual personality by a mutual plumage ornament in a passerine
TLDR
Investigating the phenotypic correlates of the black bib, a melanin-based mutual plumage ornament, in the Eurasian tree sparrow (Passer montanus) finds that bib size was not associated with body condition and cellular innate immunity/inflammation status, but was positively related to physiological stress levels independent of sex. Expand
SEXUAL SELECTION, MULTIPLE MALE ORNAMENTS, AND AGE‐ AND CONDITION‐DEPENDENT SIGNALING IN THE COMMON YELLOWTHROAT
TLDR
Age‐ and context‐dependent changes in the strength, direction, and target of selection may help explain the maintenance of multiple ornaments in this and other species. Expand
Sexual Traits as Quality Indicators in Lekking Male Great Bustards
TLDR
Whiskers may have evolved as an intrasexual indicator of weight, which in the absence of other weapons in this species is decisive in male–male combats, during both rival assessment and mate choice. Expand
Immune challenge affects sexual coloration of male Iberian wall lizards.
TLDR
It is suggested that the existence of a trade-off between physiological regulation of the immune system and the allocation of essential compounds (probably carotenoids) to sexual ornaments may allow one to honestly signal individual male quality via characteristics of coloration in lizards, which may have an important role in both intra- and intersexual selection processes. Expand
Information-content of morphological and behavioural sexual traits in the Palmate newt (Lissotriton helveticus)
TLDR
It is found that the development of the three morphological sexual traits was positively inter-correlated, and was correlated to body condition, while courtship activity, an important indicator for male reproductive success, was uncorrelated to male body condition. Expand
Variation in the peacock’s train shows a genetic component
TLDR
This study adds to the building body of evidence that high levels of additive genetic variance can exist in secondary sexual traits under directional selection, but further emphasizes the main problem of what maintains this variation. Expand
Condition-dependence, colouration and growth of red eye combs in black grouse Lyrurus tetrix
TLDR
Taking a multi-component viewpoint when studying ornament expression may be key to understanding condition-dependence and scheduling of sexual signaldevelopment in lekking black grouse. Expand

A tradeoff between immunocompetence and sexual ornamentation in domestic fowl.
TLDR
Results support the idea that a tradeoff with immune function may constrain the expression of secondary sexual ornaments, and compare comb size between male domestic chickens Gallus domesticus of lines divergently selected for antibody responses to sheep erythrocytes. Expand
Intra‐ and Intersexual Selection for Multiple Traits in the Peacock (Pavo cristatus)
TLDR
T traits under intra- and intersexual selection in a population of free-ranging common peafowl are investigated and the role of multiple receivers on the evolution of multiple signals is stressed, suggesting that females use multiple cues during mate selection. Expand
Why have birds got multiple sexual ornaments?
TLDR
Three hypotheses are examined that may account for the presence of multiple ornaments in males of many animals, including the multiple message hypothesis, the redundant signal hypothesis, and the unreliable signal hypothesis. Expand
Mate choice based on static versus dynamic secondary sexual traits in the dark-eyed junco
TLDR
It is concluded that both kinds of traits are important in junco mate choice, but that some females apparently weigh static traits more heavily than dynamic ones, while other females use opposite weightings. Expand

TLDR
I studied four characteristics of the ornamentation of male roach and found that two of them could be used to discriminate between males that are infected with either Diplozoon or nematodes, the two most severe parasites found. Expand
THE EVOLUTION OF MATE PREFERENCES FOR MULTIPLE SEXUAL ORNAMENTS
TLDR
Sexual preferences for multiple Fisher traits are likely to evolve alongside preference for a single handicap trait that indicates male quality, showing a general difference in the evolutionary outcome of these two causes of sexual selection. Expand

Condition-dependent expression of secondary sexual characters and measures of immune function in a cohort of similarly aged male blue peafowl Pavo cristatus was used to test whether different sexualExpand
Multiple sexual ornaments in satin bowerbirds: ultraviolet plumage and bowers signal different aspects of male quality
TLDR
The findings support the multiple messages hypothesis of multicomponent signals: Female satin bowerbirds should assess both male and bower features to choose the highest quality mates. Expand
The effect of past condition on a multicomponent sexual signal†
TLDR
Experimental evidence is presented of a multicomponent sexual signal that provides distinct information on male condition during different stages of life that is consistent with sexual-selection theory. Expand
Female choice for parasite-free male satin bowerbirds and the evolution of bright male plumage
TLDR
Data did not show the predicted relationship between parasite numbers with plumage quality that is needed to support the bright male hypothesis, nor did it show the inverse correlation between male condition and parasite numbers that is predicted by both the brightmale and correlated infection hypotheses.
