Sensitivity to inequity is considered be a crucial cognitive tool in the evolution of human cooperation. The ability has recently been shown also primates and dogs, raising question an evolutionary basis aversion. We present first evidence that two bird species are sensitive other individuals' efforts payoffs. In token exchange task we tested both behavioral responses quality reward (preferred versus non-preferred food) absence presence rewarded partner, 5 pairs corvids (6 crows, 4 ravens)....
Anthropogenic noise is a major pollutant in terrestrial and aquatic ecosystems. Since the industrial revolution, human activities have become increasingly noisy, leading to both acute chronic disturbance of wide variety animals. Chronic exposure can affect animals over their lifespan, changes species interactions likely altering communities. However, community-level impacts are not well-understood, which impairs our ability for effective mitigation. In this review, we address effects on...
Evidence for time-dependent calculations about future rewards is scarce in non-human animals. In primates, only great apes are comparable with humans. Still, some species wait several minutes to obtain a better reward delayed exchange tasks. Corvids have been shown match primates time-related Here, we investigate delay of gratification two corvid species, the carrion crow ( Corvus corone ) and common raven corax ), an task. Results show that corvids success decreases quickly as increases,...
Simply observing other individuals interacting has been shown to affect subsequent behaviour and also hormones in ‘bystander’ individuals. However, immediate physiological responses of an observer have hardly investigated. Here we present results on individuals' heart rate (HR) during various situations, which occur regularly a flock greylag geese ( Anser anser , e.g. agonistic encounters, vehicles passing by). We recorded simultaneously HR 21 semi-tame free-roaming geese, equipped with...
The use and manufacture of tools have been considered to be cognitively demanding thus a possible driving factor in the evolution intelligence. In this study, we tested hypothesis that enhanced physical cognitive abilities evolved conjunction with tools, by comparing performance naturally tool-using non-tool-using species suite general learning tasks. We predicted habitually species, New Caledonian crows Galápagos woodpecker finches, should outperform their relatives, small tree finches...
Abstract Animals are expected to be judicious in the use of energy they gain due costs and limits associated with its intake. The management expenditure ( EE ) exhibited by animals has previously been considered terms three patterns: constrained, independent performance patterns management. These can interpreted regressing daily against maintenance measured over extended periods. From multiple studies on this topic, there is equivocal evidence about existence universal certain aspects...
Vocal mimicry, the copying of sounds produced by another species or environment, is commonly described in vocal learners, such as songbirds. Understanding functions mimicry can help to uncover evolutionary drivers learning. Different adaptive like interspecific and intraspecific communication have been suggested, well possibility be a mistake during In present study, we review occurrence family corvids investigate socio –ecological factors driving evolution this group birds. We recorded...
Animals around the globe are strongly affected by anthropogenic disturbances, creating concerns for welfare and conservation. Fireworks during New Year’s eve a major, regularly recurring disturbance, causing light, noise as well air pollution. In present study, we investigated behavioural responses of mixed-species flocks corvids (hooded crows, Corvus cornix, rooks, frugilegus jackdaws, monedula) in Berlin. We observed direct to fireworks already day on 31st December. Behavioural included...
The ability to control an immediate impulse in return for a more desirable - though delayed outcome has long been thought be uniquely human feature. However, studies on non-human primates revealed that some species are capable of enduring delays order get food higher quality or quantity. Recently two corvid species, common raven (Corvus corax) and carrion crow corone corone), exchanged reward seemed less when exchanging the same type In present study, we specifically investigated crows...
In a number of species, consistent behavioral differences between individuals have been described in standardized tests, e.g. novel object exploration, open field test. Different expressions are reflective different coping strategies stressful situations. A causal link responses and the activation physiological stress response is assumed but not thoroughly studied. Also, most standard paradigms investigating individual differences, framed fearful context, therefore present study aimed to add...
Physical activity is generally considered as most relevant for modulating heart rate (HR). The authors show here that HR not only modulated by physical but even more social contexts. modulation in three free-ranging, socially embedded, male greylag geese fitted with implanted radiotransmitters was investigated. Measured ranged from 40 beats per minute (bpm) during rest to a maximum over 400 bpm takeoff. Almost the same HRs (400 bpm) were reached interactions, which however, require less...
Upon discovering food, common ravens, Corvus corax, produce far-reaching 'haa' calls or yells, which are individually distinct and signal food availability to conspecifics. Here, we investigated whether ravens respond differently of known unknown individuals. In a paired playback design, tested responses call sequences in group containing marked free-ranging ravens. We simultaneously played male female raven two different locations varied familiarity (known the local group). Ravens responded...
When humans and animals interact with one another over an extended time span they familiarise may develop a relationship, which can exert influence on both partners. For example, the behaviour of animal in experiments be affected by its relationship to human experimenter. However, few studies have systematically examined impact human-animal relationships experimental results. In present study we investigated if familiarity experimenter influences performance Common ravens (Corvus corax)...
Abstract Animals adaptively regulate their metabolic rate and hence energy expenditure over the annual cycle to cope with energetic challenges. We studied management in greylag geese. In all geese, profound seasonal changes of heart ( f H ) body temperature (T b showed peaks summer troughs during winter, also daily modulation T . Daily mean was on average 22% lower at winter trough than peak, whereas only about 1 °C below peak. means together those air day length were most important...
