Animals resolve conflicts over the share of resources by competing physically or signalling motivation with honest signals of need. In some species, young siblings vocally signal to each other their hunger level and the most vocal individual deters its siblings from competing for the non-divisible food item delivered at the next parental visit. This so-called sibling negotiation for forthcoming food has been studied only in this context. It therefore remains unclear whether siblings could also… Expand

Figures and Tables from this paper

Responsiveness to siblings’ need increases with age in vocally negotiating barn owl nestlings
It is shown here that older nestlings adjusted their vocal behavior more finely than younger nestlings in relation to the behavior of their siblings, suggesting that social adjustment changed with age in owlets, older ones being more sensitive to the signals of need of theiriblings. Expand
Kind to kin: weak interference competition among white stork Ciconia ciconia broodmates
The high degree of tolerance shown by senior nestlings is unusual among birds with similar ecological and phylogenetic affinities, such as herons, and cannot be easily explained by absence of parental favouritism or proximate factors known to affect the occurrence of sibling aggression in other species. Expand
Avian vocalisations: the female perspective
It is suggested that conventional male-biased definitions of songs and calls are inadequate for furthering the authors' understanding of avian vocal communication more generally, and two simple alternatives are proposed, both emancipated from the sex of the singer. Expand
Nocturnal, diurnal and bimodal patterns of locomotion, sibling interactions and sleep in nestling Barn Owls
Although adult Barn Owls are nocturnal, nestlings display a complex temporal pattern of activity that is governed not only by feeding but also by other unknown factors. Expand
Acoustic variables of high-pitched vocalizations in dairy sheep breeds
The aim of the present study was to analyze high-pitched bleats produced during a short isolation period from four dairy sheep breeds and to investigate if breed, number of offspring, presence of sibling, sex, height, activity levels and context, affect their vocal characteristics. Expand
La communication est un aspect fondamental de la vie animale car elle permet la mediation des conflits d’interets entre individus, que ce soit pour les ressources limitantes (e.g. nourriture,Expand


How siblings adjust sib–sib communication and begging signals to each other
Parents allocate food resources to their offspring in proportion to the intensity of begging behaviour. Begging encompasses several activities including vocalizations that should honestly signal needExpand
Nestling barn owls assess short-term variation in the amount of vocally competing siblings
This work tested the novel hypothesis that to optimally adjust vocal investment, barn owl nestlings assess how many of their siblings are currently competing by broadcasting a fixed global number of calls emitted by one, two or four pre-recorded unfamiliar nestlings. Expand
Individual vocal signatures in barn owl nestlings: does individual recognition have an adaptive role in sibling vocal competition?
This study suggests that sibling competition has promoted the evolution of vocal behaviours that signal not only hunger level but also intrinsic individual characteristics such as identity, family, sex and age. Expand
Barn owl (Tyto alba) siblings vocally negotiate resources
It is found that when parents are not at the nest a nestling vocally refrains when the value of the next delivered prey item will be higher for its nest–mates, the exact opposite of what current models predict for begging calls produced in the presence of the parents. Expand
Barn owls do not interrupt their siblings
It is found that barn owl nestlings avoid calling simultaneously, as overlapped calls are less efficient at deterring siblings from competing, which suggests that overlap avoidance reduces signal interference and, as a consequence, would improve the efficiency of communication among kin. Expand
Parent-absent signalling of need and its consequences for sibling competition in the barn swallow
It is shown that PAB reliably reflects need of food, indicating that a nestling will vigorously compete for the subsequent food item, and by eavesdropping siblings' PAB displays, nestlings may optimally balance the costs of scrambling competition, the direct fitness gains of being fed and the indirect fitness costs of subtracting food to needy kin. Expand
Social rules govern vocal competition in the barn owl
To resolve the share of limited resources, animals often compete through exchange of signals about theirrelative motivation to compete. When two competitors are similarly motivated, the resolution ofExpand
Efficiency and Significance of Multiple Vocal Signals in Sibling Competition
Young animals actively and differentially use multiple signaling components to compete with their siblings over parental resources and test the hypothesis that the most efficient signal to deter opponents should be the one that most honestly reveals motivation to compete. Expand
Effects of hatching asynchrony on sibling negotiation, begging, jostling for position and within-brood food allocation in the barn owl, Tyto alba
Sibling negotiation appears to influence begging behaviour, which, in turn, affects within-brood food allocation, andJuniors may negotiate to challenge their senior siblings, and thereby determine whether seniors are less hungry before deciding to beg for food. Expand
Big brother is watching you: eavesdropping to resolve family conflicts
It is shown that nestling barn owls (Tyto alba) competing for food eavesdropped on nestmates' vocal interactions to assess the dominance status and food needs of opponents and that siblings eavesdrop on one another to resolve conflicts over parental resources. Expand
