Abstract DNA fingerprinting was combined with field observations over four breeding seasons to investigate the social structure and mating system of the laughing kookaburra (Dacelo novaeguineae). Groups comprised a socially dominant pair and up to six helpers of either sex. Helpers were always recruited from young hatched in the group. Territorial inheritance, which is a feature of other cooperative breeders and an oft-cited benefit of philopatry, did not occur. Helpers only attained dominant… 
Mixed mating strategies in cooperatively breeding apostlebirds Struthidea cinerea
TLDR
Investigating mating patterns within 18 groups of apostlebirds using a set of six polymorphic microsatellite loci found that Apostlebirds appear to adopt flexible and context-dependent mating strategies, with both monogamy and polygamy detected in separate groups.
Group structure, mating system and extra‐group paternity in the co‐operatively breeding White‐breasted Thrasher Ramphocinclus brachyurus
TLDR
Investigation of the social structure and mating system of the White-breasted Thrasher Ramphocinclus brachyurus found age was associated with parentage in both sexes, and co-operative breeding was facultative in this species.
Cooperative Breeding in the Campo Flicker II: Patterns of Reproduction and Kinship
TLDR
Analysis of patterns of kinship in the Campo Flicker, a facultative cooperative breeder, revealed that the species is predominantly monogamous in both cooperative groups and socially monogamous pairs, but in several cooperative groups auxiliary females contributed eggs to the nest.
Monogamous dominant pairs monopolize reproduction in the cooperatively breeding pied babbler
TLDR
Genetic data are used from a population of cooperatively breeding pied babblers to show that reproduction is highly skewed toward behaviorally dominant birds, and helping in this species confers indirect fitness benefits on subordinates, which are likely to play an important role in the evolution and maintenance of cooperative helping behavior.
Siblicide in the cooperatively breeding laughing kookaburra (Dacelo novaeguineae)

TLDR
It is suggested that if a female hatches soon after an older but eventually smaller brother, dominance between the first two nestlings could be destabilised and this leads to escalated aggression in the nest and the death of the third nestling, which is least able to defend itself.
Demography of male reproductive queues in cooperatively breeding superb fairy-wrens Malurus cyaneus.
TLDR
Fairy-wren queues are likely to be stable because older birds are superior, and because extra-pair mating provides direct benefits to subordinates, but it is unclear why such queues should be stable.
Complex sex allocation in the laughing kookaburra
TLDR
In groups of the cooperatively breeding laughing kookaburra, offspring sex varied with the type of social group and with hatch rank, and hatching sex sequences were distributed nonrandomly: all groups avoided hatching a daughter first followed by a son (FM).
Multiple paternity in the cooperatively breeding fish Neolamprologus pulcher
In cooperative breeders, mature males may compete for fertilizations. In this study, we measured the degree of multiple paternity in a natural population of a cooperatively breeding fish.
Parentage assignment and extra‐group paternity in a cooperative breeder: the Seychelles warbler (Acrocephalus sechellensis)
TLDR
Parentage analyses showed that subordinate ‘helper’ females as well as the dominant ‘primary” females laid eggs in communal nests, indicating that the Seychelles warbler has an intermediate level of female reproductive skew, in between the alternative extremes of helper‐at‐the‐nest and joint nesting systems.
The effect of helpers on reproductive success in the laughing kookaburra
TLDR
The effects of helpers were examined in an analysis of reproductive success in the laughing kookaburra, where a monogamously breeding pair is assisted by offspring of both sexes.

TLDR
It is concluded that pukeko highlight some difficulties with conventional explanations for the "function" of dominance, and instances of males which are high on the dominance hierarchy but have only a limited reproductive output in comparison with others and malesWhich are subordinate but achieve a significant proportion of fertilizations are reported.

TLDR
Both incest avoidance and reproductive competition are important factors determining reproductive roles within groups of this highly social species by examining how reproductive roles change following breeding vacancies.

Multi-locus DNA fingerprinting supports genetic monogamy in Florida scrub-jays
TLDR
In Florida scrub-jays, large territory size may limit opportunities for cuckoldry, and persistent intense competition for limited breeding space may lead to low variance in the quality of established male breeders, which would reduce both the opportunity for, and benefits of engaging in extra-pair fertilisations.
Copulatory behaviour and paternity determined by DNA fingerprinting in kestrels: effects of cyclic food abundance
TLDR
Kestrel males successfully used both frequent pair copulation and mate guarding as complementary paternity guards, and the low frequency of EPP may reflect the importance of male parental care in determining the reproductive success of raptors.

TLDR
It is concluded that the Kookaburras's laugh song signals aggression and aids in (a) defending a temtory, (b) guarding the mate and (c) establishing and maintaining a dominance hierarchy between breeders and helpers.
