ABSTRACT. We studied mating patterns in Saltmarsh Sparrows (Ammodramus caudacutus), a species with no territorial defense, no paternal care, and no pair bonds. Fifty-seven of 60 broods with at least 2 sampled chicks (and all broods that were completely sampled) resulted from multiple mating by females. About one-third of the broods had a different father for each chick, but the most common pattern, found in 36 of 60 nests, was multiple sires, with at least 1 male having sired 2 or more chicks… 
Apparent Forced Mating and Female Control in Saltmarsh Sparrows
TLDR
The results of an observational study of mating and agonistic behavior of individually marked breeding birds in New York found no evidence of male mating aggregations, and male aggressive behavior was prevalent only in male-initiated sexual interactions.
Annual variation in the offspring sex ratio of Saltmarsh Sparrows supports Fisher's hypothesis
TLDR
The finding of a 1:1 offspring sex ratio and interannual variation in offspring and adult sex ratios in a wild bird population is more consistent with the predictions of Fisher (1930) than with those of Trivers and Willard (1973).
Successful translocation of Saltmarsh Sparrow (Ammospiza caudacuta) nestlings to new nest after loss of the attending parent
ABSTRACT Saltmarsh Sparrows (Ammospiza caudacuta) are highly specialized tidal marsh obligates that are predicted to go extinct within this century as inundation of nests becomes increasingly
Male-Skewed Sex Ratio in Saltmarsh Sparrow Nestlings
TLDR
The Saltmarsh Sparrow appears to be an exception to the pattern typical of birds, in which the population of adults is skewed toward males but the sex ratio of offspring is balanced, and future age-specific population projections for this species of high conservation concern are refined.
Females Choose Mates Based on Genetic Relatedness in a Small Dasyurid Marsupial, the Agile Antechinus (Antechinus agilis)
TLDR
The results show that genetic relatedness between mates has a significant influence on mate choice, breeding and siring success in the agile antechinus.
Divorce in an Island Bird Population: Causes, Consequences, and Lack of Inheritance
TLDR
Moderate repeatability for divorce in females (although not in males) is found but no additive genetic variance or evidence of maternal or paternal effects are found, suggesting little or no selection for the trait.
Relationship of phenotypic variation and genetic admixture in the Saltmarsh–Nelson's sparrow hybrid zone
TLDR
It is concluded that the discrimination of pure and hybrid individuals is not possible in the absence of genetic data, which has implications for conservation of pure populations, as extensive backcrossing throughout the hybrid zone may present challenges for monitoring pure species identified by morphology alone.
Testing the Role of Social Cues in Saltmarsh Sparrow Habitat Selection Decisions
The saltmarsh sparrow Ammodramus caudacutus is a species of national and global conservation concern that is threatened by its limited breeding range and vulnerability to sea-level rise. Despite
Timing of migration and prebasic molt in tidal marsh sparrows with different breeding strategies: Comparisons among sexes and species
TLDR
Observations in sympatric Saltmarsh Sparrows and Seaside Sparrows support the hypotheses that breeding strategies can influence arrival timing and that reproductive investment can have carryover effects on molt and departure.
Evolution of extreme-mating behaviour: patterns of extrapair paternity in a species with forced extrapair copulation
TLDR
It is shown that the frequency of EPP is dependent on social male and female age, the month the female fledged, breeding density and whether it was their first or second reproductive event of the season, and clutch size is the most important predictor of EPM.

Correlates of multiple paternity in the Aquatic Warbler (Acrocephalus ­paludicola)
TLDR
Paternity was determined in 64 broods in the Biebrza basin (NE Poland) studied in 1993, 1994 and 1997 by microsatellite PCR analysis and indicated that almost every young in these broods had been sired by a different father.

TLDR
Evidence suggests that, by mating with several males, C. scorpioides females may exploit postcopulatory mechanisms for reducing the risk and/or cost of embryo failure resulting from fertilization by genetically incompatible sperm.
High frequency of polyandry in a lek mating system
TLDR
The frequencies of polyandrous mating and multiple paternity in the ruff, a lekking shorebird with a genetic dimorphism in male mating behavior, are determined and active genetic diversification may apply with respect to the behavioral polymorphism.
Extra-pair paternity in Seaside Sparrows
TLDR
This study determined the prevalence of extra-pair paternity in a large, socially monogamous population of Seaside Sparrows nesting in small, overlapping territories, using six microsatellite DNA markers and a likelihood-based approach to paternity assignment.
Microsatellite analysis of female mating behaviour in lek‐breeding sage grouse
TLDR
Genetic analyses of the broods of eight females that visited an intensively studied lek were consistent with behavioural observations and confirm the reliability of mating observations at leks, but do not rule out a possible unseen component of the mating system.
EVOLUTION OF BREEDING SYSTEMS IN ACROCEPHALINE WARBLERS
TLDR
Support is found for the hypothesis that change to highly productive habitats was associated with a greater emancipation of males from brood care, and with polygyny and promiscuity, in species in the monophyletic lineage of acrocephaline warblers.
Lekking Without a Paradox in the Buff‐Breasted Sandpiper
TLDR
The results of this study suggest that sexual selection through female choice is weak in buff‐breasted sandpipers, and paternity studies of those species should be conducted to determine whether leks generally are less paradoxical than they appear.
Unusual sex roles in a highly promiscuous parrot: the Greater Vasa Parrot Caracopsis vasa
TLDR
It is proposed that female song, conspicuous head colour and territoriality have all evolved as a result of competition between females for the food provided by males in the Greater Vasa Parrot.
