In many areas of animal behaviour research, improvements in our ability to collect large and detailed data sets are outstripping analyse them. These diverse, complex often high-dimensional exhibit nonlinear dependencies unknown interactions across multiple variables, may fail conform the assumptions classical statistical methods. The field machine learning provides methodologies that ideally suited task extracting knowledge from these data. this review, we aim introduce behaviourists...

Individuals vary in their cognitive performance. While this variation forms the foundation of study human psychometrics, its broader importance is only recently being recognized. Explicitly acknowledging individual found both humans and non-human animals provides a novel opportunity to understand mechanisms, development evolution cognition. The papers special issue highlight growing emphasis on differences from fields as diverse neurobiology, experimental psychology evolutionary biology....

Abstract Animal color pattern phenotypes evolve rapidly. What influences their evolution? Because patterns are used in communication, selection for signal efficacy, relative to the intended receiver's visual system, may explain and predict direction of evolution. We investigated this bowerbirds, whose consist plumage, bower structure, ornaments displays presented under predictable conditions. data on avian vision, environmental conditions, properties, an estimate bowerbird phylogeny test...

The evolution and expression of different forms cooperative behaviour (e.g. feeding, guarding, sentinel duties, etc.) are usually studied independently, with few studies considering them as a single syndrome. However, investigating individuals' investment across suite behaviours reveal that they correlated, suggesting mechanism determining the behaviours. A hormonal could achieve this, one possibility is oxytocin (OT), which affects several prosocial or alloparental independently. We show,...

Our understanding of the processes underlying animal cognition has improved dramatically in recent years, but we still know little about how cognitive traits evolve. Following Darwinian logic, to understand selection acts on such must determine whether they vary between individuals, influence fitness, and are heritable. A handful studies have begun explore relationship variation individual performance fitness under natural conditions. Such work holds great promise, its success is contingent...

Rates of innovative foraging behaviours and success on problem-solving tasks are often used to assay differences in cognition, both within across species. Yet the cognitive features some can be unclear. As such, explanations that attribute mechanisms individual variation performance have revealed conflicting results. We investigated consistency performances captive-reared pheasant chicks, Phasianus colchicus, addressed whether depends processes, such as trial-and-error associative learning,...

Transparent Cylinder and Barrier tasks are used to purportedly assess inhibitory control in a variety of animals. However, we suspect that performances on these detour influenced by non-cognitive traits, which may result inaccurate assays control. We therefore reared pheasants under standardized conditions presented each bird with two sets similar commonly measure recorded the number times subjects incorrectly attempted access reward through transparent barriers, their latencies solve task....

Abstract In‐person academic conferences are important to disseminate research and provide networking opportunities. Whether academics attend in‐person is based on the cost, accessibility, safety of event. Therefore, less accessible stakeholders that unable overcome some these factors, which then act as a barrier equal inclusive participation. Additionally, carbon footprint conference travel increasingly becoming factor in deciding whether conference. Online may opportunities mitigate...

Young brood parasites that tolerate the company of host offspring challenge existing evolutionary view family life. In theory, all parasitic nestlings should be ruthlessly self-interested and kill soon after hatching. Yet many species allow young to live, even though they are rivals for resources. Here we show tolerance by brown-headed cowbird Molothrus ater is adaptive. Host procure a higher provisioning rate, so it grows more rapidly. The cowbird's unexpected altruism toward simply...

Cognitive abilities probably evolve through natural selection if they provide individuals with fitness benefits. A growing number of studies demonstrate a positive relationship between performance in psychometric tasks and (proxy) measures fitness. We assayed the 154 common pheasant ( Phasianus colchicus ) chicks on tests acquisition reversal learning, using different set cue types (spatial location colour) each two years then followed their fates after release into wild. Across all birds,...

Abstract Scientific conferences are a key component of academic communication and development. During the COVID‐19 pandemic, in‐person rapidly moving online, yet these virtual events may not provide same opportunities as conferences. If meetings to continue effective networking between researchers stakeholders, they must be adapted increase delegate engagement enthusiasm. Here, we present case study recent medium‐sized online conference. We assessed behavior delegates with different...

Inter– and intraspecific variations in the sizes of specific avian brain regions correspond to complexity behaviour that they govern. However, no study has demonstrated a relationship between gross size behavioural complexity, hypothesis been proposed explain unusually large human brain. I show, using X–rays museum specimens, species bowerbirds build bowers have relatively larger brains than both related ecologically similar but unrelated do not bowers. Bower design varies across from simple...

Behavioural and physiological deficiencies are major reasons why reintroduction programmes suffer from high mortality when captive animals used. Mitigation of these is essential for successful programmes. Our study manipulated early developmental diet to better replicate foraging behaviour in the wild. Over 2 years, we hand-reared 1800 pheasants (Phasianus colchicus), 1 day old, 7 weeks under different dietary conditions. In year one, 900 were divided into three groups reared with (i)...

Abstract Marine protected areas (MPAs) globally serve conservation and fisheries management goals, generating positive effects in some marine ecosystems. Surf zones sandy beaches, critical ecotones bridging land sea, play a pivotal role the life cycles of numerous fish species as prime for subsistence recreational fishing. Despite their significance, these remain understudied when evaluating MPAs. We compared surf zone assemblages inside outside MPAs across 3 bioregions California (USA)....

Parent birds often give alarm calls when a predator approaches their nest. However, it is not clear whether these alarms function to warn nestlings, nor known nestling responses are species–specific. The parental of reed warblers, Acrocephalus scirpaceus ('churr'), dunnocks, Prunella modularis ('seep'), and robins, Erithacus rubecula ('seee') very different. Playback experiments revealed that nestlings all three species ceased begging only in response conspecific calls. These differences...

It is thought that allogrooming practised strategically in order to establish, maintain and reinforce social bonds between group members, exchanging one altruistic behaviour for a different form of reciprocated benefit at later date. Correlational evidence supports this, but causality lacking. We reduced parasite loads eight meerkat Suricata suricatta groups, generating substantial decrease grooming. Contrary the predictions, overall antagonism did not increase. However, within networks,...
