Social relationships among animals emerge from interactions in multiple ecological and social situations. However, we seldom ask how each situation contributes to the global structure of a population, whether different situations contribute information about position individuals within fabric.

Animals rely on a balance of personal and social information to decide when where move next in order access desired resource. The benefits from cueing conspecifics reduce uncertainty about resource availability can be rapidly overcome by the risks within-group competition, often exacerbated toward low-ranked individuals. Being obligate soarers, relying thermal updraughts search for carcasses around which competition fierce, vultures represent ideal models investigate between during foraging movements. Linking dominance hierarchy, affinities meteorological conditions movement decisions eight captive vultures, Gyps spp ., released free flights natural soaring conditions, we found that they relied (i.e. other using/having used thermals) find updraught, especially unfavourable flight conditions. Low-ranked individuals were more likely disregard cues deciding go next, possibly minimize competitive risk aggregation. These results exemplify architecture decision-making birds. It suggests environmental context, context system as whole calibrate use.

Studying the mechanisms shaping age-related changes in behaviour ("behavioural ageing") is important for understanding population dynamics our changing world. Yet, studies that capture within-individual behavioural wild populations of long-lived animals are still scarce. Here, we used a 15-year GPS-tracking dataset social obligate scavenger, griffon vulture (Gyps fulvus), to investigate movement and behaviours, disentangle role plasticity selection such patterns. We tracked 142 individuals up 12 years found non-linear increase site fidelity with age. This pattern resulted from throughout their life (behavioural plasticity) not selective disappearance. Mature vultures increased predictability routines spent more time at prime roosting sites compared younger individuals. Thus, adults likely have competitive advantage over conspecifics. These were mirrored behaviour. Older interacted less associates (decreasing average strength age), particularly during breeding season.

Abstract Animal behaviour is often modelled as networks, where, for example, the nodes are individuals of a group and edges represent within this group. Different types behaviours or behavioural categories then different yet connected networks which form multilayer network.
