SummaryI intensively observed the mating behavior of 134 pairs of white ibises for over 15 000 pair hours to examine the responses of males to extrapair copulations (EPC) involving their mates. Females often cooperated completely in apparently fertile EPCs. Male mate-guarding was vigorous and effective. Males did not respond to apparent sperm competition with forced-pair copulation, physical punishment, or abandonment of their mates. I found no negative correlation between degree of female… 

Certainty of paternity covaries with paternal care in birds

The results suggest that the extent of paternal care has been affected by certainty of paternity, and that sex roles during the energetically most expensive parts of reproduction have been shaped by sperm competition.

Occurrence of extra-pair copulation in the tree swallow (Tachycineta bicolor)

It is proposed that frequent pair copulations are used by males to ensure their paternity in their mate's offspring, as well as to mark sperm transfer events between birds.

fi c food provisioning patterns by parents in the asynchronously hatching European hoopoe

Only females were responsive to experimentally altered chicks' hunger state, especially so with small chicks at the lower end of the size hierarchy, and this differential food allocation pattern mainly resulted from females mostly entering the nestbox to feed the chicks, while males more often delivered prey from the nest box entrance hole without entering the cavity.

Identifying parentage using molecular markers: improving accuracy of studbook records for a captive flock of marabou storks (Leptoptilos crumeniferus).

Using genetic information to verify parentage in a population of marabou stork housed at Disney's Animal Kingdom based on five microsatellite loci and to investigate reproductive behavior, genetic analyses of parents and offspring to studbook data collected through behavioral observations of parental behavior at the nest are compared.

A Review on the Correlation between Extra-Pair Copulations and Genetic Diversity in Birds

The related studies on genetic diversity are introduced and the relationship between genetic diversity and extra-pair copulations from the comparative study of intraspecies and interspecies is explored.

This paper uses mathematical models to investigate which ideas can, in theory, explain parentally biased favouritism, and which can be explained by parent-offspring conflict or sexual conflict.

Using Molecular Genetic and Demographic Tools to Improve Management of Ex Situ Avian Populations

This work describes the development and use of microsatellite development and genotyping, and the analysis of parents and children’s genomes to derive basic genetic parameters.

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.

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.

Requirements for a Mixed Reproductive Strategy in Avian Species

Male herring gulls were able to leave mates alone because of confidence of paternity provided by the female in exchange for parental effort in the form of courtship feeding, the inferred consequence of successful EPC.

Forced Copulation as a Reproductive Strategy of Male Lesser Scaup: a Field Test of Some Predictions

Predictions of the fertilization strategy hypothesis were tested with field data from a marked population of lesser scaup breeding in southwestern Manitoba, and as predicted, males directed FC attempts at fertilizable females and seemingly had tactics that increased their effectiveness in inseminating such females.

Nesting Ecology of the Little Blue Heron: Promiscuous Behavior

Overall, extramarital copulations occurred relatively infrequently, owing to: (1) the nest-guarding behavior of the pair male, and (2) the uncooperativebehavior of the female.
