Cooperative breeding in birds is thought to be more common altricial species, with few described cases precocial species. However, cooperative may also difficult detect species and could have been overlooked. We investigated whether Vulturine Guineafowl Acryllium vulturinum breed cooperatively and, if so, how care distributed among group members. collected data from 51 uniquely marked individuals (27 males, 24 females), of which 13 females bred at least once over three different seasons....
Movement is a key part of life for many species. In solitary animals, the energetic costs movement can be mitigated through energetically efficient strategies that produce faster, straighter movements. However, little known about whether moving as collective enhances or limits ability individual group members to express such strategies. Drawing on 6 years population-level, high-resolution (1 Hz) GPS tracking group-living vulturine guineafowl ( Acryllium vulturinum ), we detected 886 events...
The social decisions that individuals make-who to interact with and how frequently-give rise structure. resulting structure then determines their surroundings-resources risks, pathogens predators, competitors cooperators. However, despite intensive research on (a) make (b) shapes processes (e.g. cooperation, competition conflict), there are still few studies linking these two perspectives. These perspectives represent halves of a feedback loop: individual behaviour scales up define the...
Abstract Recent advances in technology allow researchers to automate the measurement of animal behaviour. These methods have multiple advantages over direct observations and manual data input as they reduce bias related human perception fatigue, deliver more extensive complete datasets that enhance statistical power. One major challenge automation can overcome is observation many individuals at once, enabling whole‐group or whole‐population tracking. We provide a detailed description an...
In group-living species, social stability is an important trait associated with the evolution of complex behaviours such as cooperation. While drivers in small groups are relatively well studied, little known about potential impacts unstable states on animal societies. Temporary changes group composition, a splitting and recombining (i.e. disturbance event), can result individuals having to re-establish their relationships, thus taking time away from other tasks foraging or vigilance. Here,...
Abstract GPS‐based tracking is widely used for studying wild social animals. Much like traditional observational methods, using GPS devices requires making a number of decisions about sampling that can affect the robustness study's conclusions. For example, fewer individuals per group across more distinct groups may not be sufficient to infer group‐ or subgroup‐level behaviours, while limits ability draw conclusions populations. Here, we provide quantitative recommendations when designing...
Culturally transmitted communication signals - such as human language or bird song can change over time through cultural drift, and the resulting dialects may consequently enhance separation of populations. However, emergence has been considered unlikely when songs are highly individual-specific, in zebra finch (Taeniopygia guttata). Here we show that machine learning nevertheless distinguish from multiple captive populations with remarkable precision, 'cryptic dialects' predict strong...
Abstract Dispersal is a critical, but costly, stage of life. During the active phase dispersal—called transience—individuals face many costs, from increased mortality to reduced foraging opportunities. One cost that often assumed, rarely explicitly tested, energy expended in making large dispersal movements. However, this not only determined by distance individual’s move, also how they move. Using high‐resolution GPS tracking dispersing and resident vulturine guineafowl ( Acryllium...
Abstract High population density should drive individuals to more frequently share space and interact, producing better-connected spatial social networks. Despite this widely-held assumption, it remains unconfirmed how local generally drives individuals’ positions within wild animal We analysed 34 datasets of simultaneous behaviour in >55,000 individual animals, spanning 28 species fish, reptiles, birds, mammals, insects. >80% systems exhibited strongly positive relationships between...

Movement is a key part of life for many animals. However, number temporal constraints, from changes in light and temperature to varying risks predation, limit not only where animals can move, but also when. Such constraints are likely be most pronounced when must make large displacements, as the case individuals disperse. little known about how dispersers overcome on movement, despite significant implications success dispersal. We outline general framework identifying strategies use achieve...
ABSTRACT Movement is a key part of life for both solitary and group-living animals. In animals, the energetic costs making large displacements can be mitigated by energetically efficient strategies—specifically faster, straighter movements. However, little known about whether moving as collective enhances or limits ability individual group members to express such strategies. Drawing on 6 years population-level high-resolution (1Hz) GPS tracking vulturine guineafowl ( Acryllium vulturinum ),...
Culturally transmitted communication signals – such as human language or bird song can change over time through a process of cultural drift, and may consequently enhance the separation populations, potentially leading to reproductive isolation 1–4 . Local dialects have been identified in species with relatively simple songs where individuals show high conformity 5–10 In contrast, emergence has regarded unlikely 11–13 for more variable song, zebra finch ( Taeniopygia guttata ). Instead, it...

Abstract When dispersing, individuals typically have to make large displacements. While previously thought be costly, recent work has suggested that can largely mitigate these costs by expressing distinct movement strategies—moving faster and straighter—during dispersal. Several studies also found express differences in their habitat preferences during These often involve an increased use of open habitats relative non-dispersing selection, within which achieve larger displacements per unit...
ABSTRACT Cooperative breeding is widely reported across the animal kingdom. In birds, it hypothesised to be most common in altricial species (where chicks are dependent on parental care nest after hatching), with few described cases precocial more independent immediately hatching). However, cooperative may also difficult detect and therefore has been overlooked. this study, we investigate whether vulturine guineafowl ( Acryllium vulturinum )—which have young—breed cooperatively and, if so,...
ABSTRACT Forming collectives can generate substantial benefits, but much less is known about the costs that individuals incur in doing so. We simultaneously captured individual movement, within-group position, leadership, and heart rate for each member a group of wild vulturine guineafowl. Individuals had significantly increased rates when moving collectively, occupying more central positions within group, or attempting to initiate directional movement consensus among members was low. Such...
