Whether females breed in their natal group is an important factor in the evolution of extended families in animal sociality. Breeding in natal groups comes with clear costs and benefits, depending on size of the group and presence of older relatives, including mothers. Studying individual decisions about whether to stay or leave can provide insight...
Whether females breed in their natal group is an important factor in the evolution of extended families in animal sociality. Breeding in natal groups comes with costs and benefits, depending on group size and presence of older relatives, including mothers. Studying the consequences of breeding in the natal versus another group provides insight into...
When studying social behaviour, it can be important to determine whether the behaviour being recorded is actually driven by the social preferences of individuals. Many studies of animal social networks therefore attempt to disentangle social preferences from spatial preferences or restrictions. As such, there are a large number of techniques with w...
Associating with relatives in social groups can bring benefits such as reduced risk of aggression and increased likelihood of cooperation. Competition among relatives over limited resources, on the other hand, can induce individuals to alter their patterns of association. Population density might further affect the costs and benefits of associating...
Natural disasters can cause rapid demographic changes that disturb the social structure of a population as individuals may lose connections. These changes also have indirect effects as survivors alter their within-group connections or move between groups. As group membership and network position may influence individual fitness, indirect effects ma...
When the consequences of sociality differ depending on the state of individual animals and the experienced environment, individuals may benefit from altering their social behaviours in a context‐dependent manner. Thus, to fully address the hypotheses about the role of social associations it is imperative to consider the multidimensional nature of s...
Consumer innovation, that is, the acquisition and consumption of novel food types, has received little attention, despite its predominance among animal innovations and its potential implications for the ecology and evolution of species in a changing world. Results of the few studies that have investigated individual responses to novel foods suggest...
As human populations increase and city borders grow, many animals have to modify foraging behaviors in order to exploit evolutionarily novel urban food sources that could aid their survival. Neophobia, the fear of novelty, can lead to missed opportunities in these cases. Here, we studied the novelty response of wild animals in ecologically relevant...
Individuals of many species utilise social information whilst making decisions. While many studies have examined social information in making large scale decisions, there is increasing interest in the use of fine scale social cues in groups. By examining the use of these cues and how they alter behaviour, we can gain insights into the adaptive valu...
Many animals form social groups, but the adaptive value of being gregarious often differs between individuals. It has been suggested that individuals who gain fewer benefits may only join groups due to constraints on resources. These individuals would prefer to associate loosely with a group, associate strongly with a few preferred individuals and...
Behavioural innovation, the use of new behaviours or existing ones in novel contexts, can have important ecological and evolutionary consequences for animals. An understanding of these consequences would be incomplete without considering the traits that predispose certain individuals to exhibit innovative behaviour. Several individual and ecologica...
Urbanization causes dramatic and rapid changes to natural environments, which can lead the animals inhabiting these habitats to adjust their behavioral responses. For social animals, urbanized environments may alter group social dynamics through modification of the external environment (e.g., resource distribution). This might lead to changes in ho...
Ambient noise can affect the availability of acoustic information to animals, altering both foraging and vigilance behaviour. Using captive zebra finches Taeniopygia guttata, we examined the effect of ambient broadband noise on foraging decisions. Birds were given a choice between foraging in a quiet area where conspecific calls could be heard or a...

Urban environments impose novel challenges on animals and, as a result, the behaviors of urban wildlife are changing. In particular, high exploratory tendencies and an ability to gather more information from the environment may facilitate adoption of novel ecological opportunities. As of yet, very few studies have examined if urbanization predicts...
The use of linear mixed effects models (LMMs) is increasingly common in the analysis of biological data. Whilst LMMs offer a flexible approach to modelling a broad range of data types, ecological data are often complex and require complex model structures, and the fitting and interpretation of such models is not always straightforward. The ability...
Individuals can differ in how much they benefit from being in a group depending on characteristics such as their dominance rank or their behavior. Understanding which categories of individuals influence the decisions of a group could help understand which individuals are benefiting the most. We examine these ideas in wild flocks of black-capped chi...
Understanding dominance hierarchies is an important aspect of many studies of animal groups. Collecting the necessary data requires a large amount of time and effort to detect only a small number of interactions. Here, we assess the viability of extracting interactions from a temporal data stream of arrival and departures to a feeder equipped with...

Developments in tracking technologies have enhanced our understanding of the behaviours of many seabird species. However few studies have examined the social aspects of seabird foraging behaviour, despite the effect this might have on the distribution of foraging areas and the differences that might arise between colonies. Here we use bird-borne GP...
Despite the fact that many animals live in groups, there is still no clear consensus about the ecological or evolutionary mechanisms underlying colonial living. Recently, research has suggested that colonies may be important as sources of social information. The ready availability of information from conspecifics allows animals to make better decis...
1. Selfish genetic elements (SGEs) are universal and can have major evolutionary and ecological impacts, but their ecology is not well understood. Most SGEs have stable population dynamics, but the reasons for this are rarely known. Several SGEs are distributed along latitudinal frequency clines, providing an opportunity to examine why these clines...
