The world’s most numerous bird, the domestic chicken, and their wild ancestor, red junglefowl, have long been used as model species for animal behaviour research. Recently, this research has advanced our understanding of social behaviour, personality, cognition fowl, demonstrated sophisticated cognitive skills. Here, we overview some research, starting with describing investigating well-developed senses before presenting how socially cognitively complex they can be. realisation that chickens, abundant production animal, are behaviourally should encourage an increase in general appraise fascination towards them. In turn, inspire increased use them both hobby animals, well improvements unfortunately often poor welfare.

The notion that men are more variable than women has become embedded into scientific thinking. For mental traits like personality, greater male variability been partly attributed to biology, underpinned by claims there is generally variation among males females in non-human animals due stronger sexual selection on males. However, evidence for limited morphological traits, and little information regarding sex differences personality-like behaviours animals. Here, we meta-analysed means variances over 2100 effects (204 studies) from 220 species (covering five broad taxonomic groups) across personality traits: boldness, aggression, activity, sociality exploration. We also tested if size dimorphism, a proxy sex-specific selection, explains the magnitude of personality. found no significant between sexes. In addition, dimorphism did not explain observed mean or variance any group. sum, find widespread animal

The study of consistent individual differences has become an important focus in research on animal behaviour. These behavioural are typically measured through standardized testing procedures. One frequently used paradigm is the novel object test, which animals exposed to unfamiliar objects and their reaction quantified. We meta-analysis evaluate how reliably trials quantify differences. Overall, we found repeatability responses was strong significant larger short-term than long-term studies. Average sample size estimates have both increased over past three decades. Most studies different repeated presentations, while either same or almost equally often. Novelty, time interval between interaction together explained little total heterogeneity, between-study heterogeneity remained large. estimate behaviour, but results were very heterogeneous even within species, suggesting susceptibility unknown details test conditions. that use a foraging context label trait as neophobia, neutral labelled variously shyness–boldness, exploration–avoidance neophilia.

Abstract In this study, we analyzed the variation in cognitive flexibility Chimango Caracara (Milvago chimango), across areas with different levels of urbanization. To assess this, utilized reversal learning assay which measures ability to adapt behavior response changes environmental contingencies. We also investigated impact neophobia on variation. All chimangos studied succeeded acquiring a color-reward association and reverting learned when contingencies changed. Urban were faster than their rural suburban counterparts during initial discrimination phases. The phase proved be most challenging task. analysis errors made revealed that new (i.e. regressive errors) was for individuals studied, comparison inhibiting previously one perseverative errors). Neophobia found lower urban compared raptors. Moreover, showed correlation among chimangos, while no such observed city-dwelling chimangos. suggest acted as regulating factor flexibility, mainly expressing relatively high personality trait.

Loners—individuals out of sync with a coordinated majority—occur frequently in nature. Are loners incidental byproducts large-scale coordination attempts, or are they part mosaic life-history strategies? Here, we provide empirical evidence naturally occurring heritable variation loner behavior the model social amoeba Dictyostelium discoideum. We propose that loners—cells do not join multicellular life stage—arise from dynamic population-partitioning process, result each cell making stochastic, signal-based decision. find this imperfectly synchronized development is affected by both abiotic (environmental porosity) and biotic (signaling) factors. Finally, predict theoretically when pair strains differing their partitioning coaggregate, cross-signaling impacts slime-mold diversity across spatiotemporal scales. Our findings suggest could be critical to understanding collective behaviors, development, ecological dynamics D. More broadly, taxa, imperfect behaviors might adaptive enabling diversification strategies.

SUMMARYA recent definition of animal welfare states that "the an is its positive mental and physical state related to the fulfilment physiological behavioural needs in addition expectations. This can vary depending on animal's perception a given situation'. confirms importance taking individual perspective (i.e. cognition) into consideration, order properly assess welfare. Cognitive abilities domestic chickens have been extensively studied years, but few these studies focussed relationship between chicken cognition issues commonly found production systems. Considering chickens' cognitive offers new different perspectives problems faced by production. Combined with applied research, generate impactful science-based strategies solve better. In this short non-systematic review, we focus research aimed at understanding three widespread poultry production: uneven range use free-range broiler laying hens, feather pecking unfulfilled breeders. Knowledge critical ameliorate rearing conditions develop systems practices are more respectful
