“…Taken in conjunction with the capping of grooming cliques, the fact that Samara females do not do so suggests that there may be increasing stochasticity, not only in spatial coordination, but also in activity scheduling [35]. That is, two females, who might be inclined to interact, may find themselves near each other at times when they are unable to coordinate their schedules.…”

Primate social life and behaviour is contingent on a number of levels: phylogenetic, functional and proximate. Although this contingency is recognized by socioecological theory, variability in behaviour is still commonly viewed as ‘noise’ around a central tendency, rather than as a source of information. An alternative view is that selection has acted on social reaction norms that encompass demographic variation both between and within populations and demes. Here, using data from vervet monkeys ( Chlorocebus aethiops pygerythrus ), we illustrate how this alternative approach can provide a more nuanced account of social structure and its relation to contingent events at the ecological and demographic levels. Female vervets in our South African study population live in large groups, where they experience demographic stress and increased levels of feeding competition relative to an East African population in Amboseli, Kenya. Females in the South African population did not respond to this stress by intensifying competition for high-value grooming partners to help alleviate the effects of this stress, did not show the expected rank-related patterns of grooming, nor did they show any spatial association with their preferred grooming partners. Increased group size therefore resulted in a reorganization of female social engagement that was both qualitatively and quantitatively different to that seen elsewhere, and suggests that female vervets possess the flexibility to shift to alternative patterns of social engagement in response to contingent ecological and demographic conditions.

“…However, few studies have tackled collective decision as a function of social relationships and the role of a leader [5]. Our main objective is to study the link between individual behavior, interaction between individuals, and collective responses.…”

A robot introduced into an animal group, accepted by the animals as conspecifics, and capable of interacting with them is a very efficient tool for ethological research, particularly in studies of collective and social behavior. In this paper, we present the implementation of an autonomous mobile robot developed by the authors to study group behavior of chicks of the domestic chicken (Gallus gallus domesticus). We discuss the design of the robot and of the experimental setup that we built to run animal-robot experiments. The robot design was experimentally validated, it was demonstrated that the robot can be socially integrated into animal groups. The designed system opens new opportunities in the study of behavior in domestic fowl by using mobile robots. Being socially integrated into the animal group, mobile robots can profit from the positive feedback mechanism that plays key roles in animal collective behavior. They have potential applications in various domains, from pure scientific research to applied areas such as control and ensuring welfare of poultry.

Flock size during rearing affects pullet behavioural synchrony and spatial clustering

Highlights• Behavioural synchrony and clustering in space decreased with increasing bird group size.• Preening was the most synchronised over time and feeding the most clustered in space.• Simultaneous access to resources for all is more important in small than large groups. AbstractAnimals are often synchronised in their behaviour, with costs and benefits varying according to group size and the behaviour being performed. Making decisions about optimal allocation and distribution of resources to animals in our care therefore poses theoretical and practical challenges. We investigated group size effects on behavioural synchrony and spatial clustering during daytime in pullets of a commercial laying hen strain reared until 18 weeks of age in groups of 15, 30, 60 and 120 (four replicates of each group size). Feeder, drinker, perch and litter space (i.e. floor space allowance) per bird, were constant across group sizes and all resources were continuously available. Even though the absolute numbers of birds performing the same behaviour at the same time or being located together at the same resource patch increased with increasing group size, the relative degree of synchrony of feeding, drinking, perching and preening across the whole flock decreased exponentially with increasing group size (P < 0.001 for all behaviours) as did the relative degree of clustering at the same resource patch (P < 0.001 for the same four behaviours). Preening was the most synchronous behaviour (more than twice that of the least synchronised behaviour, perching), and feeding the most clustered in space (three times more clustered than the other behaviours). These results imply that it is more important to provide sufficient resource space for all birds to perform daytime activities simultaneously when kept in the smaller group sizes typical of cages, than in the larger flocks typical of birds kept in floor pens and aviaries.
