Abstract Peacocks, Pavo cristatus, defend small display sites and aggregate to form leks. Observations of one lek, consisting of 10 males, showed that there was considerable variance in mating success. The most successful male copulated 12 times whilst the least successful males obtained no copulations. Over 50% of the variance in mating success could be attributed to variance in train morphology; there was a significant positive correlation between the number of eye-spots a male had in his… Expand
Peahens prefer peacocks displaying more eyespots, but rarely
It is shown that the maximum number of eyespots in the train is consistent among adult peacocks in feral populations at about 165-170 eyespots, and that most of the observed variation in eyespot number appears to be due to feather breakage or loss. Expand
Peahens do not prefer peacocks with more elaborate trains
It is concluded that peahens in this population are likely to exercise active choice based on cues other than the peacock's train, which is not the universal target of female choice. Expand
Variation in the peacock’s train shows a genetic component
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
Experimental and natural changes in the peacock's (Pavo cristatus) train can affect mating success
An experimental test of the importance of the peacock's train in determining male mating success supports the hypothesis that the peacocks' train has evolved, at least in part, as a result of female choice. Expand
Peacocks lek with relatives even in the absence of social and environmental cues
Two independent sets of data are presented that show that peacocks (Pavo cristatus) display close to their kin and indicate that birds can evolve a means of kin association that does not involve learning the characteristics of relatives or the use of environmental cues. Expand
Do peahens not prefer peacocks with more elaborate trains?
It is shown that plasticity in mate choice is a widespread phenomenon across a large spectrum of species and alternative explanations for the reported differences in female preferences in the peafowl are suggested. Expand
Females of the lekking great snipe do not prefer males with whiter tails
A larger correlational study showing no relationship between male mating success and whiteness of tails and evidence that individual females do not mate predominantly with males with very white tails among those males that each female samples is presented. Expand
Peacock Courtship
The glistening hues of a peacock’s (Pavo cristatus) plumage have been a source of aesthetic and scientific recognition for years. Male peacocks, known for their brightly colored jewel-toned feathers,Expand
Multiple mating in a lekking bird: why do peahens mate with more than one male and with the same male more than once?
There is competition amongst females for access to preferred males and that dominant females try to monopolise these males by repeatedly engaging them in courtship interactions, suggesting that female may gain directly from mate choice in a species where males contribute nothing but gametes to their offspring. Expand
Peahens lay more eggs for peacocks with larger trains
It is found that peahens randomly mated to males that vary in the degree of ornament produce more eggs for those peacocks with more elaborate trains, and the possibility that this difference arises as a result of difference between males in their ability to fertilize eggs is found to be unfounded.

Age‐advertisement and the evolution of the peacock's train
The blue peafowl is an appropriate species to investigate the former question of female preference for male ornaments, as it is intensely sexually dimorphic and almost invariably referred to in discussions on female choice and the evolution of sexual dimorphism. Expand
Female choice selects for a viability-based male trait in pheasants
The first experimental field data is presented showing that female pheasants select mates on the basis of male spur length and that female mate choice correlates with female reproductive success. Expand
Choosy females and correlates of male age
It is argued that (a) male age may be an indicator of fitness with older males having a higher average fitness than young males, (b) the size and complexity of many male ornaments and weapons are positively correlated with age, and (c) Mutations increasing size or complexity of the age-dependent ornament increases.

Female choice selects for extreme tail length in a widowbird
It is reported here that males in which the tail was experimentally elongated showed higher mating success than males having normal or reduced tails: males with shortened tails held their territories as long as did other males. Expand
Courtship Disruption Modifies Mate Choice in a Lek-Breeding Bird
Disruption in this rain forest species caused females to modify their courtship and mating patterns, and males that used intense and persistent disruption received a disproportionate share of this redirected mate choice. Expand
The social organization of feral peafowl
Peafowl are usually reported to have a mating system based on harem defence by adult males, but in a small feral population near Oxford, males defended small numbers of chicks in a single enclosure. Expand
