Plume Variation, Breeding Performance and Extra-Pair Copulations in the Cattle Egret

  title={Plume Variation, Breeding Performance and Extra-Pair Copulations in the Cattle Egret},
  author={Elizabeth A. Krebs and Wayne Hunte and David J Green},
We investigate how variation in breeding plumes influences pairing patterns, extra-pair copulations and breeding performance in the colonial cattle egret (Bubulcus ibis ibis). The breeding plumes of both male and female cattle egrets varied from almost none, to lush head, back and scapular plumes. Overall, male breeding plumes were longer and darker than those of females, but we observed the full range of plume development in both sexes. Plume development was positively correlated within…

Evolutionary consequences and fitness correlates of extra-pair mating in the tūī, Prosthemadera novaeseelandiae

The influence of sexual selection on the evolution of reproductive behaviours and male secondary sexual characters is investigated in the New Zealand tūī, Prosthemadera novaeseelandiae to examine correlates and fitness consequences of female within-pair and extra-pair mate choice.

Coloration, Paternity, and Assortative Mating in Western Bluebirds

It is suggested that coloration plays a role in the formation of social pairs, but not mate choice for extra-pair partners.

The role of demography in the evolution of breeding strategies

The results confirm the importance of the ASR: guarding durations increase with decreasing female availability and increasing number of male competitors, and shortening the window of fertilization shifts guarding time budgets from the postcopulatory to the precopulatory stage.

Safe betting: males help dull females only when they raise high-quality offspring

The findings suggest that the information conveyed by female ornaments may depend on direct cues of fecundity, and highlight that parental decisions are complex, modulated by a combination of information sources.

Parental Effort in Relation to Structural Plumage Coloration in the Mountain Bluebird (Sialia currucoides)

The results do not support the Good Parent Hypothesis as an explanation for the evolution of ornamental plumage color in mountain bluebirds, and alternative hypotheses are suggested.

Reconstructing genetic mating systems in the absence of parental information in colonially breeding waterbirds

Evidence that genetic monogamy occurs in Brazilian natural breeding colonies of the Great Egret, but is not the sole reproductive strategy employed by the Wood Stork and the Roseate Spoonbill is provided.

Current analyses do not resolve whether extra-pair paternity is male or female driven

This study focuses on the implicit assumption that all individuals face the same selective pressures and argues that this assumption is probably too strong in most cases and suggests giving attention to individual differences and the influence of ecological factors such as territory quality and predation pressures on female mating behaviour.

Conspecific brood parasitism in the white-faced ibis Plegadis chihi (Aves: Pelecaniformes) revealed by microsatellites' based kinship-reconstruction.

This study is the first molecular approach to better characterize the reproductive behavior of P. chihi in the wild and suggests that a non-strictly monogamous genetic mating system may be present in the white-faced ibis.

Breeding Colony Fidelity and Long-term Reproductive History of Individually Marked Wild Grey Herons

Pair bonds remained stable in four pairs throughout years until one individual in a pair was lost and the number of chicks per nest did not change with the age of the parent, and birds tend to stay at the same breeding colony once they had returned.

Use of noninvasive ‘bug-eggs’ to enable comparative inferences on genetic mating system with and without parental information: A study in a cattle egret colony

Analysis of the genetic mating system of the invasive cattle egret using hematophagous insects contained in fake eggs to collect blood from incubating adults in a wild breeding colony indicates that rates of alternative reproductive tactics inferred in the absence of parental genetic information could be underestimated and should be interpreted with caution.



Mate choice in Darwin's Finches

It is concluded that females in choosing males seek reliable indicators of potential parental care, and in addition they may seek indicators of genetic quality.

Paternal care declines with increased opportunity for extra–pair matings in fairy martins

A novel remote monitoring technique is used to show that participation in incubation by male fairy martins, Hirundo ariel, declines with the increasing availability of fertile females in the breeding colonies, and that this trade–off may be widespread among the 90% of bird species where males contribute to parental care.

Extramarital and Pair Copulations in the Cattle Egret

The behavior accompanying both pair copulations and ECs is described, quantitative data on the temporal variation in the frequency of ECs are analyzed, and underlying causal factors are considered.


The tendency for female egrets to become ready to remate earlier than males may be because they invest less prezygotic effort in second breeding attempts than males, although male-biased operational sex ratio also might favor female desertion.


Findings support the hypothesis that colonial breeding evolved in Purple Martins to increase the opportunity for extrapair fertilizations, and may be an extreme example of a general trend in breeding systems where migration and temperate climate concentrate fertile females in time and space.

Do female pigeons trade pair copulations for protection?

Female pigeons trade pair copulations for protection (mate guarding) against sexual harassment from other males, and are guarded more closely by their partner.

Extrapair Copulations in the Mating System of White Ibis (Eudocimus Albus)

Female cooperation and the efficiency of male mate guarding were concluded to be important to the evolution of this mating strategy in white ibis, which is an important strategy in this otherwise monogamous species.

Female choice and the evolution of the conspicuous plumage coloration of monogamous male great tits

The results suggest that female great tits are choosing the characteristics of the male rather than the quality of his territory, and suggests that female choice may be important in the evolution of male secondary sexual characteristics in great tits.

Male phenotype, fertility, and the pursuit of extra-pair copulations by female birds

A simple model is described, in which functional fertility (the success of ejaculates in fertilizing eggs) covaries with male phenotype, which can explain the observed associations equally well and several alternative approaches are discussed which may allow their resolution.

Female choice selects for male sexual tail ornaments in the monogamous swallow

In the monogamous swallow, Hirundo rustica, males with experimentally elpngated tail ornaments obtain mates more quickly than males with shorter tails, and enjoy increased reproductive output in one breeding season, suggesting male sexual ornament may also be maintained by female mate choice in monogamous species.
