SummaryReproduction in the blue-footed boody was examined for evidence of parent-offspring conflict over infanticidal reduction of the brood. Parental investment was analysed by measuring clutch characteristics, and chick growth and mortality in four seasons. Direct observations were made of behavioral development to determine the social roles of family members. The modal clutch was two similar-sized eggs, which hatched 4.0 days apart due to a 5.1-day laying interval and immediate incubation of… 
Adoption and infanticide in an altricial colonial seabird, the Blue-footed Booby: the roles of nest density, breeding success, and sex-biased behavior
TLDR
The sex with certainty of parenthood was more prone to practice infanticide, presumably to avoid adoption in this species, and the lack of aggressiveness by males might be due to the possibility of paternity.
The function of hatching asynchrony in the blue-footed booby
TLDR
The results suggest that natural asynchrony makes brood reduction more efficient and decreases the costs of sibling aggression to parents, in terms of their future survival or fecundity, as proposed by Mock and Ploger (1987).
Hormonal Correlates of Dominance and Starvation‐induced Aggression in Chicks of the Blue‐footed Booby
TLDR
It is suggested that corticosterone could alter responsiveness of nestling blue-footed boobies to external stimuli, resulting in more aggression by dominants and greater readiness of subordinates to submit.
Sibling rivalry in black-legged kittiwakes (Rissa tridactyla)
TLDR
It seems that eliminating within brood asymmetries is costly for the parents and perhaps these differences are optimal for maintaining a high efficiency index for theParents in terms of the amount of investment and the number of fledged chicks.
Costs of growing up as a subordinate sibling are passed to the next generation in blue‐footed boobies
TLDR
Delayed costs to blue‐footed booby fledglings of junior status in the brood, which involves aggressive subordination, food deprivation and elevated corticosterone, are analysed to indicate that systematic competition‐related differences in developmental conditions of infant siblings can alter their reproductive value by affecting the viability of their eventual offspring.
Evidence of kin-selected tolerance by nestlings in a siblicidal bird
TLDR
The indirect reproductive potential represented by a chick's sibling appears to have influenced the evolution of siblicidal brood reduction in this species.
Brown pelican siblicide and the prey-size hypothesis
TLDR
It is shown that chick loss is mediated by sibling aggression as predicted by the preysize hypothesis, and pecking during indirect feeds seems to contradict the prey-size hypothesis, but may serve partly to establish a relationship of dominance-subordinance.
Family dynamics through time: brood reduction followed by parental compensation with aggression and favouritism.
TLDR
It is shown that parent American coots (Fulica americana) practice both strategies by switching from brood reduction to compensation across time, which allows parents to compensate for the costs of competitive hierarchies while gaining the benefits of hatching asynchrony.
Siblicide, parent-offspring conflict, and unequal parental investment by egrets and herons
  • D. Mock
  • Psychology
    Behavioral Ecology and Sociobiology
  • 2004
TLDR
Mixed results are consistent with two rather different POC interpretations: (1) that significant conflict exists and the offspring are “winning” or (2) that there is no significant evolutionary conflict.
Chick Development and Asynchroneous Hatching in the Zebra Finch (Taeniopygia guttata castanotis)
TLDR
The observations suggest that the amount of care given to each chick may be equated with such factors as a camouflage effect of the down feathers, and that the low illumination within the nest also complicates the determination of the hatching order by the parents.

TLDR
Dominance rank within each SHB was formed through ritualistic fights among siblings, but in some SHBs the subordinate chicks were attacked more frequently by dominant siblings during food contests than in AHBs, and the most subordinate chick in one SHB died as a direct result of such attacks.

TLDR
How cainism might in fact be adaptive for the parents as well as for the older chick is discussed, and it is demonstrated that cainsism can be selected for even when it decreases the reproductive productivity of the adults.

TLDR
In a comparison of two species of herons in a Texas colony, great egret nestlings fought 18 times more often than adjacent great blue herons during the first month, and a general hypothesis is advanced, linking adaptive siblicidal aggression to delivered food size (specifically, monopolizability).
EGG SIZE, HATCHING ASYNCHRONY, SEX, AND BROOD REDUCTION IN THE COMMON GRACKLE'
TLDR
The overall pattern of brood reduction in this species is interpreted as an evolved system by which a 9 parent reduces risks so as to maximize inclusive fitness.
BROOD REDUCTION IN THE CURVE-BILLED THRASHER
TLDR
The purpose of this paper is to demonstrate the phenomenon in a passerine, the Curve-billed Thrasher (Toxostoma curvirostre), and demonstrate that up to a point, the parent can increase its rate of food delivery to the young by increasing its own effort.
Brood Reduction in Black-Legged Kittiwakes
TLDR
B brood reduction in Black-legged Kittiwakes (Rissa tridactyla) on St. Paul Island, Alaska was studied in 1978 and 1979, finding sibling differences frequently faalitated the removal of younger siblings from the nest by first-hatched young.
Asynchronous hatching and sibling competition in western grebes
TLDR
Feeding experiments conducted on two live-captured pairs and their newly hatched broods showed that older chicks suppressed the responses of their younger siblings to playbacks of the parental food call, thereby promoting rapid formation of a self-regulating dominance system among their offspring.
Avian Breeding Adaptations: Hatching Asynchrony, Brood Reduction, and Nest Failure
TLDR
Using a simply model of the effect of total nest failure on optimal asynchrony, it is predicted that, even in the absence of brood reduction, most bird species should commence incubation before the last egg is laid.
