Birdsong is a model of choice to explore these aspects. As repetition and diversity of song elements largely determine the overall characteristics of signals and such song characteristics as versatility and repertoire size can plastically change in different social contexts, we hypothesized that the repetition of syllables and syllable sequences could also be context dependent. Here, we used the song of the collared flycatcher as a study system. We recorded the song of focal males under different simulated sociosexual contexts (solo singing, intruder male, approaching female and counter-singing situations in the natural environment), and quantified the context-dependent changes in song structure. As well as the commonly used acoustic variables repertoire size, number of syllables in the song and versatility, we also measured the richness (number of different types) and abundance (number of occurrences) of the repeated syllables and syllable sequences in the song bout recorded in different social contexts. We found lower richness of short repeated sequences and a smaller repertoire size in the context of an approaching female compared to the solo context. Conversely, we found higher richness of long repeated sequences and songs with more syllables in counter-singing compared to the solo context in the song of the focal male. Our study provides evidence that the syllable sequences in the song bout can change depending on the social context in collared flycatchers. Our study also emphasizes the importance of considering the repetition-describing characteristics in addition to the commonly used acoustic characteristics when studying animal acoustic communication.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"219 ","pages":"Article 123026"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097326","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 placed single, wild-caught house finches in novel arenas containing a high-quality food source (sunflower seeds) and either a medium-quality (Roudybush crumble) or low-quality (5% sunflower, 95% rice hulls) food source. At one time point before infection and one time point during infection, we recorded each bird's latency to first visit each food source, number of unique feeding visits to each food source, total time spent feeding at each food source and the amount of each food source eaten. When presented with high- versus medium-quality food sources, healthy finches preferred high-quality food in terms of latency to first visit, time spent at the source and amount eaten. During infection, these preferences were lost or muted in all those metrics. When given a choice between high- and low-quality food sources, healthy birds still preferred the high-quality option, but, unlike with the medium-quality choice, this preference persisted during infection. These results suggest that finches' foraging decisions change based on infection status and available food choices. Such differences could mitigate contact rates and, therefore, pathogen transmission between healthy and sick individuals when food resources cause animal aggregation.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"219 ","pages":"Article 123023"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096945","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}

Compared with most terrestrial mammals, cetacean newborns are extremely precocious in motor and sensory development, but remain dependent on their mothers for nutrition. Little is known about the mother–calf relationship in harbour porpoises, <em>Phocoena phocoena</em>, where the high fecundity of females, short duration of lactation and precocious development of calves may challenge the amount of maternal care and the nature and intensity of interactions. We used photo-identification and drones to monitor a wild female harbour porpoise that had nine calves over 9 years and quantified her interactions with her calves aged between 1 and 5 months as a cross-sectional study. We compared their behaviour with other mother–calf pairs at 9 months postpartum. Between 1 and 9 months postpartum, the calves showed the most effort in maintaining proximity, in that the mothers were frequently observed to leave and the calves to return after separation. Across all months, the calves spent about half their time within a 2 m range from their mothers, synchronizing their respirations. While in close proximity, the calves mostly stayed in echelon position in their first month and in infant position at 2–9 months postpartum. The mothers increased distances from their calves when travelling or foraging, and the calves increasingly departed from their mothers with age for foraging, resting or exploring. The mother–calf relationship in harbour porpoises appears to be short-term and primarily maintained by calves from the first month of life. We suggest that maternal care in harbour porpoises is less pronounced than in many odontocetes because of the high fecundity of females, short interbirth interval and high energetic costs associated with gestation and lactation.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"219 ","pages":"Article 122992"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096951","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}

Efforts to combat mosquito-borne diseases mainly focus on the elimination of either adult mosquitoes or their breeding habitats. A comprehensive understanding of larval physiology and behaviour, particularly in response to light and temperature conditions, might advance the efforts of breeding habitat elimination. This study aimed to investigate the behavioural responses of mosquito larvae to temperature, light and the interaction between these two. The research was performed with <em>Aedes aegypti</em> mosquito larvae, which were tracked for 31 min with an infrared camera in water-filled aluminium trays that were subjected to different temperature and lighting conditions. The larvae exhibited a preference for cooler temperatures in all three gradients (10–20°C, 20–30 °C, 30–40 °C) under light conditions, aligning with the behaviour of adult mosquitoes. This preference is believed to be an adaptive response to avoid heat stress in their natural breeding habitats. However, in the 20–30 °C gradient without light, the larvae displayed a more even distribution around the point of release. Furthermore, when both temperature and light gradients were present, the larvae initially (until minute 15) demonstrated negative phototaxis. Only later (after 15 min) did they prefer the cooler side. This suggests that <em>Ae. aegypti</em> larvae eventually prioritize thermotaxis. Movement analysis revealed that larval velocity was higher at the initial release site and at higher temperatures. Intriguingly, the larvae were more active during the dark phase, possibly to enhance their exploration and foraging abilities when visual predators are less active. These results highlight the complex interplay of the environmental cues temperature and light in shaping the behaviour of mosquito larvae.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"219 ","pages":"Article 123011"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097328","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}

Previous studies have indicated that certain species responded differently to calls of different individuals. Investigating individual level recognition in animals is, however, challenging, as distinguishing it from class level recognition (e.g. familiar/unfamiliar) is difficult. Previous studies showed that dogs, <em>Canis familiaris</em>, can choose their owner's voice from among strangers' voices, but whether this performance reflects class or individual level recognition remained unclear. Here, dogs had to choose the vocalizer from among three familiar speakers (owners) based on prerecorded speech in a cross-modal match-to-sample task. We predicted that if dogs are capable of voice-based individual level recognition, they will successfully match the voice to the vocalizer. Dogs' behaviour and its association with acoustic distance between speakers were analysed. Our results showed that, on the group level, dogs' choosing success and the proportion of the time dogs spent looking at the target owner were significantly above chance. Dogs' performance, however, was not significantly correlated with speakers' acoustic distance in either of the measured cues. The performance of choosing the speaker from among familiar people provides evidence for individual level recognition in dogs. Further research will have to reveal the contributions of specific acoustic cues to this performance.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"219 ","pages":"Article 123016"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097330","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 repeatability of the lateralized behaviour is a precondition of its correlation with fitness traits. Currently, studies on the repeatability of behavioural lateralization are mainly focused on captive animals, with knowledge about wild populations remaining scarce. We examined the repeatability of the preference of foot use (i.e. footedness) for grasping food against a perch in wild-caught Japanese tits, <em>Parus minor</em>, by testing a group of captive-raised birds within 16 days and testing the birds living in the wild, with a recapture interval ranging from 0 days to 1169 days. We found that an individual's sex and test interval did not affect its footedness score. High repeatability of footedness was found for both the captive group and the wild-recapture group. Across different recapture intervals of the wild-recapture group (0−60 days, 61−120 days, 121−365 days, >1 year), repeatability varied between 0.765 and 0.989, suggesting consistent foot use preference across seasons. Compared to the lateralized behaviours in most other species, footedness in wild Japanese tits showed a higher level of repeatability. We suggest that the birds in the family Paridae could be ideal systems for understanding the evolution of behavioural/cerebral lateralization for their potential to explore the interplay between lateralization and other fitness-related behaviours in the wild.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"219 ","pages":"Article 122997"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096923","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}
