Altricial birds show enormous intraspecific diversity in their provisioning strategies, in terms of both the provisioning rate and the amount of food delivered per feeding bout. Extra‐pair copulations (EPCs), which result in either extra‐pair paternity (EPP) or maternity (EPM), provide an opportunity to demonstrate why provisioning strategies vary among individuals. Because EPP‐cuckolded males and EPM‐cuckolded females must raise unrelated young, whereas EPM‐cuckolded males and EPP‐cuckolded… 

Coevolution of female fidelity and male help in populations with alternative reproductive tactics

An analytical population genetics model and an individual-based simulation model are used to explore the coevolution of female fidelity and male help in populations with two genetically determined alternative reproductive tactics (ARTs): sneakers that achieve paternity solely via extra-pair copulations and bourgeois that form a mating pair and spend some efforts in brood care.

Fitness consequences of divorce in the azure-winged magpie depends on the breeding experience of a new mate

Azure-winged magpies provide novel insights into the implications of sexual conflict in birds and it appears that divorced females can obtain an advantage in sexual conflicts with inexperienced mates in future reproduction.

Males and females of a polygamous songbird respond differently to mating opportunities

It is shown that male penduline tits abandon their offspring in response to enhanced mating opportunities while the female parental behavior remains unaffected, implying the relationship between mating opportunities and parental care is more complex than currently acknowledged and requires further investigation.

Inter-individual variation in provisioning rate, prey size and number, and links to total prey biomass delivered to nestlings in the Collared Flycatcher (Ficedula albicollis)

Background In bird species where offspring growth and survival rely on parents’ food provisioning, parents can maximise their fitness by increasing the quantity and/or the quality of preys delivered

Parental dependence on the nest’s spatial cues in offspring recognition decreases with nestling growth in the azure-winged magpie

It is suggested that azure-winged magpies switch their cues in offspring recognition during the different stages of reproduction, and after parent–offspring communication has been established, the offspring’s phenotypic traits may become a more reliable cue than the nest’S spatial position in offspring Recognition.

Female preferences for male golden snub-nosed monkeys vary with male age and social context

Abstract Age is a key factor affecting sexual selection, as many physical and social traits are age-related. Although studies of primate mate choice often consider particular age-related traits, few

Azure‐winged Magpies Cyanopica cyanus trade off reproductive success and parental care by establishing a size hierarchy among nestlings

It appears that parent birds can better trade off reproductive success and parental care by establishing a size hierarchy among nestlings, and the same reproductive success as those of synchronized broods based on less parental care.

Extra-pair paternity and egg dumping in birds: life history, parental care and the risk of retaliation

The results are interpreted as supporting the idea that alternative reproductive strategies are most common in taxa in which the risks of retaliation are low, with high rates of reproductive cheating being associated with ‘fast’ life histories.

Experimentally reduced paternity affects paternal effort and reproductive success in pied flycatchers

A study on pied flycatchers, Ficedula hypoleuca, in which paternity was manipulated through experimentally induced mate switching during the female's fertile period suggests that there are significant costs of parental care in this species.

High paternal investment in unrelated young: extra-pair paternity and male parental care in house martins

Extra-pair fertilizations enhanced the reproductive success of some males because they were able to parasitize the parental care of cuckolded males, discussing several conditions which may favor extensive male parental care even when the male's paternity is very low.

Male reed buntings do not adjust parental effort in relation to extrapair paternity

This study investigated whether male reed buntings exhibit a reduction in paternal care (incubation and provisioning nestlings) in relation to decreased paternity, and whether males bias their provisioning toward kin.

Extrapair Paternity and Maternity in the Three-Toed Woodpecker, Picoides tridactylus: Insights from Microsatellite-Based Parentage Analysis

The levels of extrapair parentage were low, possibly Because both genetic polygyny and polyandry are constrained by the high paternal effort required for parental care, in a socially monogamous population of three-toed woodpeckers in southern Finland.

Biochemical determination of parental uncertainty in white-fronted bee-eaters

A comparison of estimates from biochemical and behavioral analyses indicates that both methods can produce misleading results, and a possible use of maximum likelihood techniques to separate the sources of non-kin is discussed.

Extra pair paternity in birds: a review of interspecific variation and adaptive function

The remaining challenges of understanding the relative roles of genes and ecology in determining variation between taxa in the rate of extra paternity are highlighted, and testing for differences between extra‐pair offspring and those sired within‐pair is highlighted.
