Summary Behavioural responses to novelty, including fear and subsequent avoidance of novel stimuli, behaviours referred as neophobia, determine how animals interact with their environment. Neophobia aids in navigating risk impacts on adaptability survival. There is variation within between individuals species, however, lack large-scale, comparative studies critically limits investigation the socio-ecological drivers neophobia. In this study, we tested objects food (alongside familiar food) versus a baseline (familiar alone) 10 corvid species (241 subjects) across labs worldwide. were differences latency touch object conditions relative baseline. Three seven factors influenced neophobia: 1) use urban habitat (vs not), 2) territorial pair vs family group sociality 3) large small flock size (whereas range, caching, hunting live animals, genus did not); while only We found that, overall, temporally contextually repeatable (i.e. consistent) novelty all conditions, indicating neophobia stable behavioural trait.

These findings enable us, first time corvids, identify correlates grant insight into specific elements that drive higher neophobic avian group.

Human-wildlife interactions, including human-wildlife conflict, are increasingly common as expanding urbanization worldwide creates more opportunities for people to encounter wildlife. Wildlife-vehicle collisions, zoonotic disease transmission, property damage, and physical attacks or their pets have negative consequences both wildlife, underscoring the need comprehensive strategies that mitigate prevent conflict altogether. Management techniques often aim deter, relocate, remove individual organisms, all of which may present a significant selective force in urban nonurban systems. Management-induced selection significantly affect adaptive nonadaptive evolutionary processes populations, yet few studies explicate links among wildlife management, evolution. Moreover, intensity management can vary considerably by taxon, public perception, policy, religious cultural beliefs, geographic region, underscores complexity developing flexible tools reduce conflict.

The cognitive mechanisms causing intraspecific behavioural differences between wild and captive animals remain poorly understood. Although diminished neophobia, resulting from a safer environment more "free" time, has been proposed to underlie these among settings, less is known about how captivity influences exploration tendency. Here, we refer the combination of reduced neophobia increased interest in exploring novelty as "curiosity", which systematically compared across seven groups vervet monkeys (Chlorocebus pygerythrus) by exposing them test battery eight novel stimuli. In sample, included both habituated human presence unhabituated individuals filmed using motion-triggered cameras. Results revealed clear number approaches stimuli captive, wild-habituated wild-unhabituated monkeys. As foraging pressure predation risks are assumed be equal for all monkeys, our results do not support relationship curiosity safety or free time. Instead, propose "the habituation hypothesis" an explanation why well-habituated approached explored than individuals. We conclude that varying levels and/or artefact habituation, rather present natural environments, better explain variation sample

Abstract Urban environments expose animals to abundant anthropogenic materials and foods that facilitate foraging innovations in species with opportunistic diets high behavioral flexibility. Neophilia exploration tendency are believed be important traits for thriving urban environments. Vervet monkeys (Chlorocebus pygerythrus) one of few primate have successfully adapted environments, thus making them an ideal study these traits. Using a within-species cross-habitat approach, we compared neophilia novel objects (jointly referred as “object curiosity”) between semi-urban, wild, captive shed light on the cognitive facilitating living. To measure curiosity,” exposed various types stimuli their approaches explorative behavior. Our results revealed differences number behavior toward habitat considered. Captive vervet were significantly more than both semi- wild troops, suggesting positive experiences humans lack predation, rather exposure human per se, influence object curiosity. Across habitats, juvenile males most age-sex class. This is likely due being dispersing sex juveniles motivated learn about environment. Additionally, found items potentially associated food, elicited stronger responses semi-urban non-food related objects, motivation explore might driven by “anthrophilia”, is, experience rewarding similar food sources.

Abstract Urbanization is changing natural landscapes worldwide, pushing species to quickly acclimate or adapt if they are survive in urban environments. Mountain chickadees (Poecile gambeli) readily nest both and rural environments without suffering apparent reproductive costs. However, whether urban-nesting successful these due differences behaviour between birds remains untested. We examined the behavioural responses of nesting mountain chickadee females when presented with a novel object (red plastic cup) simulated predator (imitation squirrel model) at nest. Behavioural depended on type model habitat. As expected, responded more strongly models than objects; however, magnitude difference response Urban seemingly ignored object, spending little time investigating, re-entering box quickly. In contrast, spent reacting alarm calling within 5 m When model, reacted relatively (compared stimulus) birds, calling. These results suggest that either acclimatize presence objects or, potentially, less neophobic disproportionately settle experience positive selection areas. Either way, reduced neophobia may aid chickadees’ ability successfully such habitats.
