Because 95.5% of breeding eastern bluebirds on study sites in South Carolina were apparently monogamous, I examined hypotheses for the evolution of monogamy. In an effort to assess the effects of male parental care on female reproductive success, males were removed from breeding territories after clutch completion. Experimentally deserted females and control, paired females were matched by age, brood number, habitat type, and study area. No significant differences were found for any measures of… 

Male plumage, paternal care and reproductive success in yellow warblers, Dendroica petechia

Paternal care was highly variable between individuals and females did not compensate for experimentally induced reductions of paternal care, which resulted in significantly reduced nestling growth.

Food availability, parental care and male mating success in red-winged blackbirds (Agelaius phoeniceus)

Red-winged blackbirds breeding at two marshes in Alberta, Canada that differed substantially in food availability were examined, finding that nestling mortality due to starvation was lower, and unassisted females fledged more offspring at the woodland marsh than at the agricultural marsh.

Polygyny and male parental care in Savannah sparrows: effects on female fitness

The benefits of polygyny for male Savannah sparrows are clear: polygynous males recruit more surviving offspring into the breeding population than monogamous males and unassisted females did not suffer diminished fledging success or produce smaller fledglings.

Replacement males in the western bluebird: opportunity for paternity, chick-feeding rules, and fitness consequences of male parental care

It is suggested that male parental care increases nesting success in western bluebirds and that replacement males use an all-or-none rule to determine whether or not to feed chicks: if they are present during the fertile period they feed at typical rates; if they is not, they usually do not feed at all.

Fitness consequences of male parental care in Savannah sparrows

This research suggests that the proximate and ultimate targets of male feeding effort can be distinct; traditional assumptions regarding the function of male parental care in birds may therefore be incomplete.

Importance of monogamous male birds in determining reproductive success

House wrens (Troglodytes aedon) is addressed by removing males early in the nestling stage, concluding that when males appear to be helping, their absence usually results in decreased survival of young whereas when the males render little apparent care their absence does not decrease survival of the young.

Certainty of paternity and paternal investment in eastern bluebirds and tree swallows

It is argued that females might have restored the males' confidence in paternity after the experiment by soliciting or accepting copulations, and males may not reduce their effort, because the fitness costs to their own offspring may outweigh the benefits for the males, at least in populations where females cannot fully compensate for reduced male investment.

Asymmetric costs favor female desertion in the facultatively polyandrous northern flicker (Colaptes auratus): a removal experiment

It is demonstrated that when parental care roles are reversed in altricial birds, asymmetric benefits can favor female and not male desertion.

Male parental care and monogamy in snow buntings

It is suggested that monogamy is a bet-hedging strategy in case of poor food availability and may explain why snow buntings are almost always monogamous.



Microgeographic Prediction of Polygyny in the Lark Bunting

Field experiments on breeding populations of lark buntings in South Dakota support the hypothesis that polygyny is promoted by a high variance in quality among male territories, and the mating status of males was predicted accurately in new areas of Colorado and North Dakota before females arrived.

The Influence of Habitats on Mating Systems of North American Passerine Birds

Regardless of sex ratio, a polygynous mating is expected to be adaptive for the females as well as for the male, and marshes and prairies are more likely than forests to present the minimum requisite food supply and sufficiently great differences in available food between territories for selection to favor polygyny.

Breeding Adaptations in the Eastern Bluebird

This paper examines bluebird nesting adaptations, particularly those relating to the temporal organization of the breeding season, and compares nesting performance in yearling and adult birds, and test the hypothesis that breeding costs energy and reduces the physiological condition of the adults.


It is pointed out that if sexual selection results in sexual dimorphism expressed during the period of parental care, there may be a change in average expenditure per sex with a consequent change in sex ratio, and mate preference, which in my opinion should have a profound influence on the mating system, may also have an effect on the sex ratio.

Relative Fecundity and Parental Effort in Communally Nesting Anis, Crotophaga sulcirostris

The amount of parental care performed by each bird is correlated with relative egg ownership for both sexes and the contribution of eggs to the communal clutch by females of the group is significantly skewed.

Evolution of Social Organization and Life-History Patterns Among Grouse

Calculations of rates of reproductive increase for hypothetical lineages of males indicate that these compensating conditions can plausibly explain the evolution of delayed reproduction among male grouse, andoretical considerations suggest that larger size could favor the evolved evolution of deferred reproduction, especially in males, and thus could contribute to the Evolution of sexual bimaturism and polygyny in the larger species of grouse.


The purpose of this paper is to document polyandry and certain related phenomena in the American Jaana, a circum- tropical family of shorebirds that inhabit freshwater swamps and marshes and has been considered polyandrous in a number of other orders.

Polygyny and Decision Theory: Testing of a Model in Lark Buntings (Calamospiza melanocorys)

In the lark bunting, a grassland "sparrow," polygyny occurs and the decision arises from the solution of a conflict between seasonal and lifetime expected utility (number of fledged young).

Evolution of Polyandry in Birds

Comparisons of the existing polyandrous systems suggest that they can be arranged in a sequence that leads through a series of relatively minor differences from monogamy to simultaneous polyandry.
