Moreover, these behavioural responses may vary depending on the individual's own characteristics. By showing video fragments with different social content (i.e., run, conflict, sit, groom) of group members and strangers, we measured the reaction of captive long-tailed macaques living in multi-generational groups. In addition, we explored how an individual's social and self-directed behaviour in its social group was related to reactions to these videos. Subjects paid more attention to videos of group members than strangers, especially more subordinate and less stress sensitive (i.e., low stress response when observing natural aggression) individuals. Self-directed behaviour was higher for younger individuals seeing strangers, but not group members, and for individuals with high levels of baseline self-directed behaviour and little grooming. Regarding context, the monkeys paid more attention to videos with active and aggressive content compared to sitting and grooming videos. Altogether, monkeys living in multi-generational groups show high interest in gathering social information on group members, and this is modulated by their social role and personal ability to handle social situations.","PeriodicalId":7879,"journal":{"name":"Animal Cognition","volume":"28 1","pages":"50"},"PeriodicalIF":1.9,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12198264/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144482905","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}

Hama had learned 50 types of behaviors, but her social learning ability was unknown. In Study 1, we trained Hama to produce simultaneous DAID responses. After introducing the DAID training, we conducted four tests to confirm Hama's acquisition of demonstrator-matching behavior. We found that Hama successfully acquired the action-matching ability for human actions, not only with three trained actions but also with six out of seven untrained actions (see Test 1 and Test 2). Moreover, Hama's DAID performance was stable regardless of the familiarity of human demonstrators (see Test 1 and Test 2). Hama successfully performed two completely novel body actions that were not included in her prior learning repertoire, but failed to replicate actions involving object manipulation (see Test 3). She showed no response in control trials without demonstrations, providing partial evidence for negative control (see Test 4). In Study 2, we introduced Hama to performing non-simultaneous DAID responses, which involved suppressing immediate simultaneous actions following the demonstrator and then reproducing the actions upon the verbal cue \"Go.\" She accurately performed the DAID response even when she delayed her response until the demonstrator's demonstration was completed (Test 5). Importantly, she reproduced the action accurately when visual contact between the demonstrator and herself was blocked after the demonstration, eliminating the Clever Hans effect as a potential influence on her simultaneous DAID response (Test 6). However, she could not reproduce small or untrained actions (Test 7). These results suggest that Hama may be able to accurately map human action sequences in body-oriented actions to some extent. This study provides the first evidence of motor imitation ability in captive pinnipeds.","PeriodicalId":7879,"journal":{"name":"Animal Cognition","volume":"28 1","pages":"49"},"PeriodicalIF":1.9,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12181110/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144332340","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}

The consensus is that these novel urban challenges act as drivers for increased cognitive abilities. However, scant empirical data validates the idea that urban environments are cognitively demanding relative to native ones. In this short communication we draw the attention to the fact that for some large-brained urban inhabitants the urban environment may instead provide \"easy\" exploitable niches, where these species can thrive because they already have the necessary cognitive tools in place. As such, evolutionary seen, such species are \"exapted\" to occupy a less challenging urban niche. As follows, while a species' cognition may facilitate its persistence under urbanization, it does not necessarily mean that urban populations face selective or developmental drivers for improved cognition in urban living. We further point out the potential bias anthropogenic habituation can bring about when intraspecific comparisons are made between urban and nonurban populations and suggest that researchers must focus on precisely which species-specific aspects of the environment are novel when making predictions about the consequences of urbanization on cognitive traits.","PeriodicalId":7879,"journal":{"name":"Animal Cognition","volume":"28 1","pages":"48"},"PeriodicalIF":1.9,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12174247/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315768","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}

For example, the female cuckoo's bubbling call putatively mimics the call of the Eurasian sparrowhawk (Accipiter nisus) to serve as defence from host songbirds mobbing the parasitic female. However, several other, both raptorial and harmless, sympatric bird species also have similar vocalizations to the bubbling call (including the Eurasian kestrel, Falco tinnunculus, and the Eurasian green woodpecker, Picus viridis). Bubbling calls are also used by female cuckoos for conspecific communication with male conspecifics and so the discrimination of acoustically similar con- vs. heterospecific calls should be functionally relevant for cuckoos. We expanded upon a published playback study with all the above species' calls presented to male cuckoos. The subjects approached the speaker in 100% when conspecific females' bubbling calls were played back, but rarely (6-12%) did so when either acoustically similar natural calls of sympatric species were used. However, as structurally the bubbling call has no harmonic overtones, but the calls of the other species contain them, we also conducted playbacks with manipulated sound files where the harmonics were removed. Harmonic-free heterospecific calls attracted male cuckoos more often (40-50%) than natural heterospecific calls but still less so than the natural conspecific call. These results reveal the functional importance of the presence of harmonical overtones in heterospecific calls as they can serve to reduce perceptual auditory errors in male cuckoos.","PeriodicalId":7879,"journal":{"name":"Animal Cognition","volume":"28 1","pages":"45"},"PeriodicalIF":1.9,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12141366/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144224072","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}

Usually, these different food types, although potentially of different value to the birds, are all palatable and would be consumed when encountered. We report on the responses of coal tits (Periparus ater) to peanut pieces that were made distasteful with quinine. While birds preferred eating normal peanut pieces over quinine-soaked ones, they were still very likely to hoard the distasteful nuts. Birds also did not distinguish between the two nut types when retrieving them after 30 min. These findings point towards the compulsive and automatic nature of hoarding decision, independent of the value of the food being hoarded. We discuss how high hoarding motivation may interact with eating motivation to drive natural patterns of hoarding intensity in the field. Our findings also suggest that the taste of hoarded food items is not part of the representation of the cache memory. We speculate that this may be because tasting the item and caching the item happens in separate locations and are therefore not associated with each other.","PeriodicalId":7879,"journal":{"name":"Animal Cognition","volume":"28 1","pages":"44"},"PeriodicalIF":1.9,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12141390/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144224073","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}

Given that past methodological inconsistencies have led to mixed results and conclusions across various species, we then designed experiments that incorporate the critical components of WM, facilitating cross-species comparisons and accounting for potential ecological influences. We present such experiments on WM in an ectothermic vertebrate, the cleaner wrasse (Labroides dimidiatus), which faces environmental challenges potentially requiring complex cognitive adaptations. Overcoming several experimental challenges, we consistently obtained negative results across multiple experimental paradigms. As our experiments were specifically designed to test WM, our negative results call into question previous studies in other fish species that provide evidence for WM using different paradigms. More specific tests for WM should be developed to confirm the presence or absence of this executive function in other ectotherm vertebrates. The absence of WM may be a key factor underlying the significant encephalization gap between ectotherm and endotherm vertebrate species.","PeriodicalId":7879,"journal":{"name":"Animal Cognition","volume":"28 1","pages":"43"},"PeriodicalIF":1.9,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12137418/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144214643","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}

Some females exhibited intense nest defense behavior when human-simulated intruders approached. Notably, individuals exhibiting high nest defense behavior had significantly shorter tail lengths compared to individuals who did not. In addition, bold individuals would exhibit higher nest defense behavior than those showing low defense responses. Furthermore, bold individuals consistently demonstrated stronger nest defense behavior compared to shy individuals, aligning with their proactive personality traits.

Numerous studies utilising spontaneous quantity discrimination tasks have found that a wide range of species possess the ability to discriminate between quantities, with large interspecific differences being found in these capabilities. However, the causes of variation in quantity discrimination have received less attention, particularly when considering intraspecific variation. Here, we use a spontaneous quantity discrimination task to (i) investigate if Western Australian magpies possess quantity discrimination abilities, and (ii) determine the factors that underlie individual variation in this ability. We found that magpies were able to discriminate between two discrete quantities of a food reward and chose the larger quantity of food more often than expected by chance, with their accuracy increasing as the difference between the two quantities of food items increased (i.e. as the ratio decreased). Individual performance on the assay was significantly affected by group size, with individuals from smaller groups choosing the larger quantity of food more often than individuals from larger groups when presented with the 2 vs. 5 combination. This group size difference may arise because individuals from smaller groups benefit more from enhanced quantity discrimination abilities compared to individuals from larger groups due to the greater risk of competition and loss of resources from intergroup conflict with larger groups. Our study is the first to investigate and identify group size as a source of intraspecific variation in spontaneous quantity discrimination abilities and highlights the importance of considering the causes of individual variation in cognitive performance.</div>","PeriodicalId":7879,"journal":{"name":"Animal Cognition","volume":"28 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10071-025-01963-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135367","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}
