Avian siblicide, whereby some chicks are eliminated from a brood as a direct consequence of sibling aggression, has often been interpreted as the outcome of a parent-offspring conflict over brood size This conflict, which arises from the fact that each offspring values itself more than it values its siblings, results in offspring favoring smaller families, of higher-quality individuals, than would be optimal for their parents to produce. Considered as an evolutionary game, this conflict is… 
The evolution of siblicide
A review and discussion of some of hypotheses with greater impact in the study of the evolution of kin aggression in birds, focusing on avian taxa, pointing out a few erroneous assumptions that have been made and some limitations of the inclusive fitness framework.
Lethal sibling rivalry for nest inheritance among virgin ant queens
The authors' observations add a novel case of siblicide to the previously reported lethal aggression among nestling birds, parasitoid larvae, and honey bee queens, and corroborate the hypothesis that relatedness does not play a significant role in local competition for highly limited resources.
Parent blue-footed boobies suppress siblicidal behavior of offspring
Evidence of post-hatching parental regulation in blue-footed booby broods is consistent with Theory predicts selection for such regulation in siblicidal birds that are likely to experience genetic parent-offspring conflict over the value of subordinant nestlings.

This paper uses mathematical models to investigate which ideas can, in theory, explain parentally biased favouritism, and which can be explained by parent-offspring conflict or sexual conflict.
Sibling competition stabilizes signalling resolution models of parent–offspring conflict
It is shown that when direct sibling competition is introduced into the model, in such a way that parents have control on the amount of food provided to the nest, but not on the way the food is allocated among siblings, the non‐signalling equilibrium disappears and the signalling equilibrium becomes stable.
A focus on confl ict is an understandable refl ection of changing notions of the family and, in particular, revision of the earlier, somewhat romantic notion that close kin must live harmoniously because of their shared genetic interests.
Parental interference in sibling aggression in birds: What should we look for?
It is proposed that parents may use “general remedial behaviours as a long-term strategy to ensure adequate resources to disadvantaged offspring, and “acute responses” involving physical contact, distraction, or deception, to halt particular aggressive acts.
Brood reduction and begging behaviour in the Swift Apus apus; no evidence that large nestlings restrict parental choice
It is suggested that parent Swifts can easily access small nestlings, but prefer either to allocate more food to larger nestlings or to allow sibling competition in order to facilitate brood reduction.
Sibling aggression, hatching asynchrony, and nestling mortality in the black kite (Milvus migrans)

In this facultatively siblicidal species, cainism does not seem to be the final stage of an evolutionary trend favouring the raising of high-quality chicks, but a manifestation of a parent-offspring conflict over brood size.


Avian Brood Reduction and Parent-Offspring "Conflict"
Model analysis revealed that both conflict and cooperation over brood size are possible ESSs, and parental fitness was diminished slightly by despotic allocation, but the risk of parent-offspring conflict was also diminished.
The Role of Brood Size in Regulating Egret Sibling Aggression
It is proposed that species probably do best by relying on current food amount for the truncation of sibling fighting whenever that cue allows an accurate assessment of pending competition, with brood size used mainly as an alternative or backup system.
Signaling of Need between Parents and Young: Parent-Offspring Conflict and Sibling Rivalry
It is shown that an evolutionarily stable signaling system can exist in which the parent obtains accurate information about the resource needs of its young and on which it bases its resource distribution decisions.
Hatching asynchrony and reproductive success in the blackbird
By manipulating both food availability and brood hierarchies, and following offspring survival after fledging, it is shown that in blackbirds (Turdus merula) asynchronous broods are more productive whenFood is scarce, but not when food is abundant.
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.
