Permanent monogamy may be the most prevalent mating system in birds because most birds are tropical residents found as pairs in territories that are defended throughout the year. Long-term pair bonds may be advantageous to individuals with respect to current and future reproductive success. Conversely, each member may be constrained to remain with the current mate because of limited opportunities to acquire new mates. These alternative hypotheses were evaluated for permanently monogamous… 

Causes of divorce in long-term monogamous bird species

ed from Black et al., 1996. A long-term monogamous pair bond means increasing coordination and cooperation between pair members, longer parental investment of both parents and less costs in general

Territory size and stability in a sedentary neotropical passerine: is resource partitioning a necessary condition?

It is suggested that Dusky Antbirds do not partition resources and that territory switching, rather than resource partitioning, may be the means by which they gain access to additional food resources.

Fitness advantages, low resource availability and selection for resource monopolization by males and females may have favoured long-term monogamy in Buff-breasted Wrens.

Trading up: the fitness consequences of divorce in monogamous birds

By providing strong evidence that divorce is an adaptive strategy across monogamous birds, this review provides a firm ground for further exploration of external covariates of divorce (e.g. demographic factors) and the mechanisms underlying the differences in the effect sizes of the proximal fitness causes and consequences of divorce.

Dynamic pair bonds in hylobatids: implications regarding monogamous social systems

These longitudinal sociodemographic data suggest that gibbon pair bonds are not necessarily life-long and that adults may leave mates permanently or temporarily, sometimes in order to exploit new reproductive opportunities.

Why Monogamy? Comparing House Wren Social Mating Systems In Two Hemispheres

Comparing life-history traits and mating systems between a northern and a southern house wren population studied over a five-year period shows monogamy is expected to be more common in southern temperate birds.

Mate change in a socially monogamous mammal: evidences support the “forced divorce” hypothesis

The results support the "forced divorce" hypothesis in the Alpine marmot and suggest that mate switching has strong consequences on breeding success and the importance of taking into account the cases of forced divorce while studying mate switching process and its evolutionary consequences in monogamous species.

No evidence of immediate fitness benefits of within-season divorce in monogamous birds

No evidence that within-season divorce is adaptive for breeding success is found, but the large heterogeneity of effect sizes and strong phylogenetic signal suggest social and environmental factors—which have rarely been considered in empirical studies—may play an important role in explaining variation among populations and species.

This analysis emphasizes the importance, in double-brooded species, of the territory being large enough to provide food for the entire family group until the young reach independance.

On the Evolution of Mating Systems in Birds and Mammals

Most cases of polygyny in birds, a group in which monogamy is the most common mating pattern, can be explained on the basis of the model, and those cases not apparently fitting into the predictions are clearly indicated.

The "Underworld" in a Territorial Sparrow: Adaptive Strategy for Floaters

A tropical population of Rufous-collared Sparrows, Zonotrichia capensis, with year-round territoriality and breeding, included about 50% nonterritorial floaters, which could evolve wherever membership will increase a floater's chances to breed and where the costs to the owner of having floaters in its territory are less than the costs of driving them out.

The Evolution of Monogamy: Hypotheses and Evidence

Mating system theory revolves around two major issues: the factors determining which sex predominates in shap­ ing each mating system, and the factors deciding which mating system is optimal for members of the "controlling" sex.

Rufous-and-White Wrens kill House Wren nestlings during a food shortage

The infanticide appears to be based on competition for food since nestlings were killed only during an 8-week food shortage within a 4-year period and Predators were probably not responsible for the killings.

Results of several experiments support both the variant-energy hypothesis and the cost-expansion hypothesis, and the amount of clutch overlap should increase as organisms gain reproductive experience, which is expected to occur in ecological time.

A 1960—71 study of populations of color—banded ant—following antbirds of three species on a tropical—forested lowland reserve, Barro Colorado Island, showed that the small species remained stable at about 20 pairs/km2, but the medium and large species declined, with no clear reasons for declines.

Reproductive Costs in the House Martin (Delichon urbica)

The most important finding of the study was that double- Brooded females survived less well (especially if they bred early) than single-brooded ones and this did not apply to males and there was no age-specific change in mortality for double brooded birds of either sex.
