Abstract Behaviorally dominant nestlings routinely kill sibling nestmates in blue-footed booby (Sula nebouxii) broods during periods of food shortage. Previous work demonstrated that these dominant, first-hatching “A-chicks” regulate the lethality of their behavior towards subordinate, second-hatching “B-chicks,” showing tolerance towards B-chicks except during chronic food shortages. Siblicide by A-chicks usually occurs after the hatchling stage. Results of an interspecific cross-fostering…

Nestling aggression in broods of a siblicidal kingfisher, the laughing kookaburra
- Biology
- 2001
The third-hatched nestling seems to experience some of the "overflow" of aggression occurring between its two older siblings, which is unsurprising because siblicide occurs when feeding rates are comparatively low.
Is obligate siblicidal aggression food sensitive?
- PsychologyBehavioral Ecology and Sociobiology
- 2003
The less food an older nestling ingested, the more time it spent active and the greater its rate and absolute frequency of pushes, and the more often it expelled its nestmate, suggesting deficient food provision to older nestlings could precipitate siblicidal expulsion of broodmates.
Competitive positioning as an indicator of nestling survival in red-cockaded woodpeckers.
- Environmental Science
- 2009
Nestling behavior in five populations of red-cockaded woodpeckers in peninsula Florida from 1997–2003 and 2007 revealed novel mechanisms and behavioral positioning of crossed, disproportionately long necks in all nestlings, showing that those with elevated levels of aggressive behavior fledged significantly fewer young.
Contributions of marginal offspring to reproductive success of Nazca booby (Sula granti) parents: tests of multiple hypotheses
- BiologyOecologia
- 2005
Investigating the evolution of clutch size in Nazca boobies found no evidence for the resource-tracking hypothesis, and evaluation of the Insurance Egg Hypothesis showed that marginal and core offspring are functionally equivalent in the absence of sibling interactions, and that core offspring incur no detectable costs from behaving siblicidally.
Siblicide in the cooperatively breeding laughing kookaburra (Dacelo novaeguineae)
- Environmental ScienceBehavioral Ecology and Sociobiology
- 2000
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.
Hormonal Correlates of Siblicide in Galápagos Nazca Boobies
- Biology, PsychologyHormones and Behavior
- 2001
It is suggested that CORT and P are regulated to promote exaggerated mass gain in socially challenged A-chicks, facilitating siblicide.
Parental interference in sibling aggression in birds: What should we look for?
- Psychology
- 2000
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.
Siblicidal brood reduction in South Polar Skuas
- Biology
- 2003
Brood reduction through siblicide in this species is a two‐phase process: eviction from the nest area, followed by death from predation, exposure or starvation, which is uniquely confined to this species within the Stercorariidae.
Parent–offspring and sibling conflict in Galápagos fur seals and sea lions

It is presented the first examples of deadly conflict between siblings of different cohorts in Galápagos fur seals and sea lions, where up to 23% of all pups are born while the older sibling is still being nursed.

Estimates of inclusive fitness of chicks in experimental broods were higher than were those of control nestlings, a result inconsistent with the POC hypothesis that the siblicidal offspring's optimal brood size is one while the parents' optimum is greater than one.

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.

Siblicide: The Evolutionary Blackmail

Siblicide can be viewed in these instances as evolutionary blackmail, because its threat is sufficient to make parents increase brood provisioning levels and sibling aggression may acquire a signaling role in the parent-offspring interplay.
