Repeatability in behaviour within a specific context, termed temperament or trait-like behavioural responses, fosters adaptive responses to stimuli. Behavioural plasticity, on the other hand, enables state-like responses, aligning behaviour with internal and external conditions. The nutritional state of an organism significantly impacts behaviours and may interact with temperament. However, the specific contributions of trait- and state-like responses to stimuli remain poorly understood. Using a long-term data set on mule deer, <em>Odocoileus hemionus</em>, elk, <em>Cervus canadensis</em>, and bighorn sheep, <em>Ovis canadensis</em>, we assessed the interplay of temperament and nutritional state in behavioural responses during handling. We measured the repeatability of kick rates across multiple capture events over time, investigating its association with temperament, nutritional condition, age and capture frequency. Bighorn sheep and mule deer exhibited high repeatability in kicks during capture, while elk did not. State-dependent factors, such as body fat, minimally influenced kick rates during capture. In bighorn sheep and mule deer, trait-like responses were likely related to temperament, whereas elk demonstrated neither state- nor trait-like behavioural responses. Trait-like responses in these species may reflect adaptations to specific ecological niches and site-specific evolutionary pressures. Our findings advance our understanding of these mechanisms, shedding light on the complex interplay between temperament, nutritional state and behaviour. Nevertheless, our results highlight the need for caution when predicting or extrapolating behavioural responses to stressors across closely related species.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"221 ","pages":"Article 123056"},"PeriodicalIF":2.3,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This can lead to behavioural changes or disorders that can damage the animal–human relationship. In social species such as horses, <em>Equus caballus</em>, social contact is a fundamental need that is severely restricted by individual housing. Thus, this study aimed to evaluate the impact of socialization on the emotional state of horses in different contexts. We studied 20 adult horses housed in individual stalls. The horses were divided equally into two experimental conditions: horses without social interaction (isolated condition) and horses with the opportunity to interact temporarily with a conspecific (social condition). For 4 months, the horses under the social condition interacted in pairs for 1 h daily in a meeting box. Throughout this period, the behaviour of the entire sample of horses in individual stalls and during grooming sessions with humans was recorded. In addition, a judgement bias test was conducted at the end of the study period. In the individual stall, we collected indicators of poor welfare such as hypervigilance, apathy, aggressiveness towards humans and stereotypies. During grooming, we observed negative and positive behaviours, alertness levels and general attitude. Horses in the social condition exhibited fewer stereotyped behaviours in the individual stall than the isolated ones. During grooming, they expressed fewer negative behaviours, spent less time in a vigilant state and showed a less tense attitude. In the judgement bias test, horses in the social condition showed an optimistic bias compared with the isolated horses. These findings indicate that horses that are allowed to interact socially perceive their environment more positively than their isolated counterparts. Temporary but regular social contacts positively affect the emotional state of horses in various contexts, indicating an overall improved welfare.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"221 ","pages":"Article 123055"},"PeriodicalIF":2.3,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Males developed in either stable or variable temperatures, and then experienced a mismatch in thermal conditions at independence. Their crystallized song was recorded at adulthood, and their song learning and quality traits were evaluated. Condition mismatch affected only song traits acquired during development, with a decrease in the proportion of syllables copied from the tutor and a trend towards decreasing repertoire size.

Subspecies of the variable seedeater, <em>Sporophila corvina</em>, that differ dramatically in plumage colour have established secondary contact at two independent contact zones in Costa Rica and Panama. We first evaluated divergence in song in allopatric populations close to the most recent contact zone (Costa Rica), where the two subspecies do not hybridize, and found significant differences in song structure and composition of song elements between subspecies. Then, we used an experimental approach to measure a territorial male’s aggressive response to visual and acoustic signals, as a proxy of the role of divergent secondary sexual traits in reproductive isolation. These playback experiments did not show clear effects of divergent colour or song on aggressive response: we found no effect of plumage coloration or song in one subspecies and males of the other subspecies were more aggressive towards homotypic songs but, unexpectedly, also more aggressive towards to heterotypic plumages. Separately, we also characterized the song structure of hybrid individuals from the Panamanian contact zone to evaluate how songs covary given evidence for gene flow. These hybrid individuals sang songs of different element composition than allopatric subspecies but did not differ in most acoustic characteristics. Overall, our experiments suggest that reproductive isolation based on secondary sexual signals is weak in this group, and after secondary contact, the breeding phenology may synchronize and divergent acoustic signals may homogenize, facilitating further hybridization.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"221 ","pages":"Article 123072"},"PeriodicalIF":2.3,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the ecological and social drivers of vocal communication is key to enhancing our understanding of the evolution of social structures, mating systems and group dynamics. We reviewed 130 studies investigating vocal communication in the family of corvids. As oscine passerines, living in complex and flexible social systems and a wide range of ecological systems (e.g. different habitats, trophic niches), corvids present a key model group in advancing our understanding of evolutionary drivers of vocal communication. Here, we outline empirical evidence for vocal learning, ecological adaptation (e.g. calls encoding information about predator type) and social adaptation (e.g. vocalizations for group cohesion and coordination) in corvid vocalizations and behavioural responses of receivers to calls. Only 35 out of 128 (27%) of corvid species have been studied with regards to their vocal communication. While some species, like American crows, common ravens and Eurasian magpies, are well studied, and supporting evidence for vocal learning and ecological as well as social adaptations is available, most corvid species remain poorly studied. We hope our review will inspire future work on previously underinvestigated corvid species, as well as replications of previous research with standardized observational and experimental paradigms, to allow for direct comparison between different corvid species. More broadly, further research systematically investigating social and ecological factors driving variation in vocal communication systems is necessary to further advance our general understanding of animal vocal communication.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"221 ","pages":"Article 123073"},"PeriodicalIF":2.3,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We currently assume that predators should maximize their foraging success by foraging in habitats where prey are easier to detect and search times are lower. Mesopredators, however, have to detect prey (as a predator) while also avoiding detection by their own predators (as prey). The predicted trade-off between foraging success and perceived predation risk for mesopredators is likely to be affected by the visual complexity of their surroundings, although this remains to be tested. Using two immersive augmented-reality experiments, we tested whether risk aversion and foraging success of a model mesopredator (individual three-spined sticklebacks, <em>Gasterosteus aculeatus</em>) changed in habitats with differing visual complexity. Despite being motivated to forage, individuals consistently preferred to associate with regions of higher complexity. However, contrary to our predictions, sticklebacks also had higher foraging success in these habitats. This appeared to be driven by increases in exploration and foraging in visually complex habitats, changing their likelihood of encountering prey. Our findings highlight how environmental visual complexity alone can induce a behavioural shift in mesopredators from risk-averse behaviours to those associated with exploration and foraging, ultimately changing where and when predators choose to hunt while mitigating predicted trophic trade-offs.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"221 ","pages":"Article 123057"},"PeriodicalIF":2.3,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we examined the relationship between acoustic and morphological trait spaces of bird flocks in Peninsular India, using a phylogenetically informed framework. We found that participant species were generally more similar in body mass than expected by chance, and flocks in general were dominated by smaller-sized species. Conversely, we found that flock participants did not exhibit this pattern of similarity for acoustic frequency traits. Thus, in spite of the correlation of vocal frequency with traits such as body size and bill size, body mass and spectral signal space were decoupled at the community scale.

Multiple theories have been put forward regarding which factors influence the probability that a host nest will be parasitized. One of these, the perch proximity hypothesis, predicts that nests that are close to trees are more likely to be parasitized, as trees provide a vantage point for the parasite to observe nest building by the host. Substantial support for this hypothesis has been found in several species of brood parasites that occur in a range of open habitats, such as reed beds, marshlands and grasslands, where vantage points are likely to be scarce. However, it is unclear whether this prediction applies to species that occupy woodland habitats. Although brood parasites may be more likely to exploit nests with suitable vantage points nearby, it is possible that a high density of vegetation might obscure the nest, thereby reducing the likelihood of parasitism. Here we used a long-term data set of superb fairy-wren, <em>Malurus cyaneus</em>, nests to test this hypothesis in the brood-parasitic Horsfield’s bronze-cuckoo, <em>Chalcites basalis</em>. Contrary to the prediction of the perch proximity hypothesis, parasitism risk did not increase with closer proximity of a perch to the nest; instead, we show that the risk of parasitism may decrease as tree density increases.
