Sexual selection that results in the evolution of exaggerated secondary sexual characters has been hypothesized to impose production and maintenance costs of such traits on their bearers. Costs arising from sexual selection could increase the intensity of predator-mediated natural selection, leading to the prediction that species with exaggerated secondary sexual characters should be particularly susceptible to predation. We tested this prediction in a comparative analysis based on 31,745 prey… Expand

Figures and Tables from this paper

Flight initiation distances in relation to sexual dichromatism and body size in birds from three continents
TLDR
FID differed among continents and the relative difference in FID between sexually monochromatic and sexually dichromatic species was larger in Europe than in Australia and North America, which may be attributed to latitudinal effects of predation. Expand
Genetic variation in birds in relation to predation risk by hawks: A comparative analysis
TLDR
Findings indicate that prey species with high band sharing coefficients, and hence low levels of ge- netic variation, are more readily caught by avian predators, and predation may constitute a major cost of low level of genetic variation. Expand
Intensity of Melanin-Based Color and Risk of Predation in the Barn Swallow Hirundo rustica
TLDR
It is suggested that Barn Swallows with long tails that fail to deposit large amounts of melanin in their tail feathers run an elevated risk of predation. Expand
Sex differences in lizard escape decisions vary with latitude, but not sexual dimorphism
TLDR
It is hypothesized that this sex difference in risk-taking behaviour is linked to sex-specific environmental constraints that more strongly affect the reproductive effort of females than males, and has important implications for responses to climate change and for the relative roles of natural and sexual selection in different species. Expand
Spatial consistency in susceptibility of prey species to predation by two Accipiter hawks
TLDR
It is suggested that hawks impose similar selection pressures on their prey populations, and that the degree of consistency in the goshawk was higher than in the sparrowhawk, which has implications for intensity of interspecific killing. Expand
Malaria and risk of predation: a comparative study of birds.
TLDR
It is demonstrated that protozoan infections are a common cause of death for hosts mediated by increased risk of predation, and predation is an important factor affecting parasite-host dynamics because predators tend to prey on hosts that are more likely to be infected, thereby reducing the transmission success of parasites. Expand
MALARIA AND RISK OF PREDATION: A COMPARATIVE STUDY OF BIRDS
TLDR
It is demonstrated that protozoan infections are a common cause of death for hosts mediated by increased risk of predation, and predation is an important factor affecting parasite-host dynamics because predators tend to prey on hosts that are more likely to be infected, thereby reducing the transmission success of parasites. Expand
Causes of interspecific variation in susceptibility to cat preda­tion on birds
TLDR
Findings suggest that predation by cats has been an important selection pressure affecting anti-predation behavior, sexual display and immune function in common birds. Expand
Sexual signals, risk of predation and escape behavior
TLDR
It is suggested that exposure to risk of predation has modified escape behavior in relation to sexual coloration, and species with the most exaggerated signals should expect to have evolved antipredator behavior that reduces or eliminates predation costs of sexual signaling. Expand
Evolution of sexual dichromatism in relation to nesting habits in European passerines: a test of Wallace’s hypothesis
TLDR
A role of nesting habits in the evolution of plumage conspicuousness of males, and a role for sexual selection also in females, are strongly suggested, which partly support the evolutionary scenarios envisaged by both extraordinary scientists. Expand

PLUMAGE BRIGHTNESS OF PREY INCREASES PREDATION RISK: AN AMONG-SPECIES COMPARISON
TLDR
The authors' analyses provide evidence that predation may impose viability costs on sexually selected traits such as plumage brightness and body size, and suggest that in northern harsh conditions, Sparrowhawks may prefer large prey in order to fulfill their daily energy requirements. Expand
Differential predation cost of a secondary sexual character: sparrowhawk predation on barn swallows
TLDR
There was a negative relationship between degree of sexual ornamentation and predation risk, consistent with the hypothesis that the secondary sexual character is a reliable indicator of quality. Expand
Comparative evidence supports the Hamilton and Zuk hypothesis on parasites and sexual selection
TLDR
Positive relationships between male brightness and parasite prevalence which remain when the effects of taxonomic, behavioural and ecological variables are removed are demonstrated. Expand
Altitudinal variation in sexual dimorphism: a new pattern and alternative hypotheses
TLDR
As predicted, interspecific variation in sexual dimorphism was more strongly associated with changes in elevation than with habitat, nest dispersion and placement, and migratory status, and species occupying lower elevations were more sexually dimorphic in plumage than species at higher elevations. Expand
Prey Selection by Sparrowhawks, Accipiter nisus: Relative Predation Risk for Breeding Passerine Birds in Relation to their Size, Ecology and Behaviour
TLDR
Most predation was due to the smaller male hawks, providing food for their mates and young, RPR increased with prey body size up to a mass of about 40 g, then declined with increasing body size (larger prey being more difficult to catch), RPR decreased with increasing relative density of prey species.

Immune Defense and Host Sociality: A Comparative Study of Swallows and Martins
TLDR
It is shown that the impact of parasites on host reproductive success was positively associated with the degree of sociality in the bird family Hirundinidae, however, the cost of parasitism in highly colonial species was countered by high levels of T‐ and B‐cell immune responses. Expand
Anti-predator effect of conspicuous plumage in a male bird
TLDR
Stuffed pied flycatchers were exposed to sparrowhawks and contrary to the assumption of sexual selection theory, the hawks attacked dull-coloured females more often than conspicuous males, providing the first experimental evidence for the unprofitable prey hypothesis. Expand
THE EVOLUTION OF PLUMAGE BRIGHTNESS IN BIRDS IS RELATED TO EXTRAPAIR PATERNITY
TLDR
Brightness of male plumage and sexual dimorphism in brightness were positively associated with high levels of extrapair paternity, even when potentially confounding variables were controlled statistically. Expand
Conspicuous coloration in male birds is favoured by predation in some species and disfavoured in others

Conspicuous plumage in male birds may evolve through competition between males and choice of bright males by females. Male brightness might be constrained by increased risk of predation or otherExpand
Predation favours cryptic coloration in breeding male pied flycatchers
TLDR
The data suggest a cost associated with conspicuous coloration in male pied flycatchers, and support the view that predation may help explain sexual dimorphism in bird coloration, delayed plumage maturation, and why males inspecies with less male parental care are more colourful than males in species with moremale parental care.
