Individuals may be selective in when and to which individuals they attend, which may be influenced by social context (e.g. observer identity) and development. In 10 carrion/hooded crows, <em>Corvus corone corone/C. c. cornix</em>, and nine common ravens, <em>Corvus corax</em>, we tested the influence of social context (alone, sibling/affiliate, nonsibling/nonaffiliate, heterospecific) on behavioural responses (item manipulation, caching and ‘head and body out of sight’, i.e. barrier use) with familiar food and objects. We tested subjects during development at fledging (1–2 months), juvenile (3–8 months) and subadult (14–18 months old) stages. Subjects were hand reared and housed in comparable conditions. These two species are closely related, generalist corvids, which will routinely cache (i.e. hide food and other items for later recovery) and engage in cache-pilfering (stealing) strategies. Item manipulation and caching may contribute to the development of physical and/or social skills. Subject behaviour was influenced by social context, with birds showing higher frequency of ‘head and body out of sight’ (barrier use) behaviour with (any) observer present than when alone. Observer identity had no effect, suggesting item interaction may have facilitated development of physical (rather than influencing social) skills in this setting. There were developmental effects, including increased manipulation and use of barriers as juveniles, and increased caching with age. Ravens cached more than crows. Objects were manipulated more frequently than food. Barriers were used more with food, indicating food was more actively hidden, while object manipulation may promote low-risk interaction and learning. We discuss our findings in relation to social and developmental influences on behaviour, in relation to social attention across ontogeny in animals.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"220 ","pages":"Article 123038"},"PeriodicalIF":2.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143179421","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}

During play fighting, animals perform ‘competitive’ actions that are typical of the agonistic context and/or ‘cooperative’ actions to avoid escalation into aggression. Several structural features of play fighting (asymmetry, duration, variability and repetition) provide information on whether a session is more, or less, competitive. In many mammalian species, the relaxed open mouth (ROM) is a metasignal that communicates that the interaction is playful. In the Felidae family, play fighting has been poorly investigated and it is challenging to tell whether play fights are cooperative or competitive. Here, we explored whether the ROM could provide information about the cooperative/competitive nature of play fighting in felines. To do so, we videorecorded and analysed dyadic play-fighting interactions in kittens of domestic cats, <em>Felis silvestris catus</em>, and Asian leopard cats, <em>Prionailurus bengalensis</em>. For both species, we found that play-fighting sessions with ROM were more symmetric, lasted longer, were less variable and showed lower evenness and repetition than those without ROM. As a whole, our results suggest that in both species ROM may help manage unpredictable play-fighting sessions and therefore this signal can be used to increase cooperation during the playful interaction, thus prolonging it.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"220 ","pages":"Article 123042"},"PeriodicalIF":2.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143179404","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}

To disentangle how exactly these factors contribute to male mate choice for size in <em>E. malaccana,</em> we employed modified versions of a previous mate choice experiment using a range of female and male size classes. Mate choice was measured from the same male individuals across different experimental days, thus allowing the analysis of the repeatability of male preferences, as well as the comparison of the strength of mate choice with previous experimental designs and data from wild populations. Two parallel experiments (presenting either the same or different female individuals to males across days) were conducted, which allowed the inference of whether size alone, or additionally with other traits, influences mate choice. Results showed that male preference for females slightly larger than themselves remained consistent in both experiments, although its specific characteristics (e.g. strength of preference, extent of size bias) differed from previous studies. This suggests that the estimation of mate choice in <em>E. malaccana</em> is sensitive to experimental approaches and, to a certain extent, context dependent. The repeatability of mate choice (0–0.36) was only significant in the experiments where males were presented with the same female individuals.

In the context of avian research, limited literature exists on longitudinal changes in antipredator behaviour during incubation and potential selection pressures on a specific trait. We studied the response of common goldeneye, <em>Bucephala clangula</em>, to disturbance, mimicking a predation threat in a nestbox population from 1984 to 2021. From a total of 652 captured females, 516 were recaptured as breeders 2–15 times over the study period. During the nest-monitoring visits, female behaviour was classified as ‘shy’ (flushing before the human observer reached the nestbox, or they flew into the net placed over the nest hole), ‘average’ (leaving the nest when the observer scratched the nestbox wall, or they showed inconsistent flush patterns such as once behaving shy and once bold in the same year), or ‘bold’ (leaving the nest once physically touched or they did not leave at all). Our results provide evidence of plasticity of antipredator behaviour, since the probability of exhibiting a bold reaction to a perceived predation danger increased with age, whereas shy individuals became less common. On the other hand, we found a high level of repeatability of behavioural response across individuals. The findings reveal the coexistence of plastic and personality traits among common goldeneye females. Moreover, there was a positive linear interaction between age and clutch size on boldness, but only for clutches below the parasitism threshold (fewer than 13 eggs). Interestingly, hatching success was not related to behaviour, suggesting no direct selection pressure on antipredator behaviour and that depending on age/residual reproductive value, either shy or bold types are favoured to benefit the lifetime reproductive success of individuals.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"220 ","pages":"Article 123046"},"PeriodicalIF":2.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143179279","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}

Typically, standardized behavioural assays are used rather than in situ tools. We evaluated whether assays and accelerometry, a relatively novel method of quantifying animal behaviour in the field, yielded similar personality measurements in a wild population of North American red squirrels, <em>Tamiasciurus hudsonicus</em>, by comparing among-individual correlations of behaviours across these methods. Both methods described two behavioural axes, with assays capturing activity and exploration, and accelerometry capturing foraging and movement. We found higher trait repeatability (<em>R</em>) for traits measured with assays (<em>R</em>_adj: adults: 0.37–0.40; yearlings: 0.18–0.48) than for traits measured with accelerometry (<em>R</em>_adj: adults 0.11–0.19; yearlings: 0.07–0.11). Additionally, we found a significant positive among-individual correlation between the assay behavioural axis associated with exploration and the accelerometry behavioural axis associated with foraging. We also found that the repeatability of traits measured with accelerometry was related to the amount of behavioural data captured by this method. Given that accelerometry was able to quantify animal personality in situ for adults, accelerometer collars may present a possible alternative to assays for species in which assays are impractical.

The state–behaviour feedback hypothesis suggests that variations in personality that drive foraging strategies may be influenced by their physiological states. Appetite hormones, such as leptin and ghrelin, play a crucial role in regulating the host’s foraging behaviour. In addition, the digestive tract is essential for the digestion and absorption of nutrients, which is related to feed efficiency and the host’s foraging behaviour. However, the potential role of appetite hormones and digestive tract morphology as the basis for personality-driven foraging behaviour remains unclear. Thus, in this study, we used the Chinese three-keeled pond turtle to investigate how the boldness–exploration personality syndrome affects food intake and its association with morphological traits, hormones and digestive tract morphology between different personality types. We found a positive link between boldness–exploration personality and physiological state; bolder and more explorative turtles had higher food intake, lower stomach and intestine mass along with shorter stomach and intestine. However, no differences in morphology and serum leptin and ghrelin concentrations were found between these two personality types. Our results indicate that personality could affect foraging behaviour probably because of its association with digestive tract morphology. These results provide new evidence of behavioural–physiological adaptation mechanisms in animal personality, suggesting that personality-related foraging behaviour may covary with the physiological state. Individuals with different personalities may adaptively adjust their foraging behaviour based on their digestive tract morphology. These associations may lead to individual dietary specialization and contribute to achieving a potentially similar fitness expectation of different personalities in nature.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"221 ","pages":"Article 123069"},"PeriodicalIF":2.3,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096754","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}

It is also unclear whether such compensation influences the behaviour of eavesdropping heterospecifics. The common cuckoo, <em>Cuculus canorus</em>, an obligate brood parasite, produces a distinct innate ‘cu-coo’ call by males. We conducted field playback experiments during the breeding season using synthesized normal and aberrant (with syntax error, ‘cu-cu-coo’) cuckoo calls, as well as control wood pigeon calls. Our findings showed that cuckoos responded most strongly to high-rate normal cuckoo calls, followed by low-rate normal calls, while showing significantly less interest in syntactically aberrant and control calls, regardless of call rate. Noncuckoo (potential host) bird species also responded most strongly to high-rate normal cuckoo calls, but their response to low-rate normal and high-rate syntactically aberrant calls was similar. These results suggest that while cuckoos and other bird species primarily respond to normal cuckoo calls, noncuckoo species may still respond relatively strongly to high-rate syntactically aberrant calls.

In this study, the link between magnitude and space in honey bees, <em>Apis mellifera</em>, was investigated to improve our understanding of the evolution of space and quantity associations in diverse taxa. First, we tested whether free-flying honey bees have an innate left-to-right or right-to-left bias for associations between quantity and space similar to the MNL and whether bees showed any evidence of a vertical preference. Along the horizontal orientation, bees only showed a preference for larger quantities on the right, indicating a left-to-right magnitude bias interacting with a weak right spatial bias. No evidence of a vertical magnitude preference was observed as bees had an overall ventral preference. Whether honey bees could be conditioned to order quantities along the left-to-right or right-to-left dimensions of quantity and space was also determined. Although honey bees could learn either a left-to-right or right-to-left quantity and space association during conditioning trials, in subsequent unconditioned tests, they only demonstrated a significant preference for arranging larger quantities on the right when trained to a left-to-right quantity association.

Focusing on boldness as a personality trait, we assessed how personality components (mean, among- and within-individual variabilities, repeatability and plasticity in response to environmental complexity) develop at early age. Investigating development of all personality components, rather than averages only, offers a more exhaustive and comprehensive picture of how personality emerges, develops and evolves. We compared personality components between juveniles of five morphs of Arctic charr, <em>Salvelinus alpinus</em>, ranging along gradients of ecological and genetic divergence from a common ancestor, raised from hatching in plain versus structurally complex treatments. On the one hand, our results showed that some of these personality components evolve and develop independently from the others: mean boldness, which increases with divergence from the ancestor, was predominantly genotype dependent and suspectedly a highly heritable trait with strong and stable selective pressures acting on it in the wild, while boldness repeatability might rather depend on the ecology of each morph. These two components were not affected by environmental complexity. On the other hand, variability-related components of personality, including their plasticity in response to environmental complexity, were rather dependent on genotype-by-environment effects and seemingly evolve and develop jointly. Boldness tended to be more consistent within the treatment mimicking the structural complexity of a given morph's natural habitat, hinting that personality emergence might be favoured for individuals experiencing conditions to which they have been adapted. These findings suggest mechanisms by which personality components could be implicated in adaptability to environmental changes or even sympatric diversification and biodiversity.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"221 ","pages":"Article 123077"},"PeriodicalIF":2.3,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096155","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}
