“…Birds had a signi cant bias in the observation of the source of disturbance and hadn't in the observation of the leading partner. This result corresponds to the previous funding for White-fronted geese and Barnacle geese (Zaynagutdinova et al 2020). In this study, geese had the visual lateralisation bias in following the partner throughout the entire annual cycle, but they hadn't any preferences under the disturbing conditions.…”

“…Furthermore, it was found that disturbances could in uence the manifestation of the visual lateralisation bias, at least during the interaction between partners in the wild. For example, visual lateralisation was manifested in routine behaviours of Barnacle geese (Branta leucopsis) and Greater white-fronted geese (Anser albifrons), but lateralisation was lacking in disturbing conditions (Zaynagutdinova et al 2020).…”

Visual lateralisation is manifested in the dominance of one brain hemisphere in the processing of information from one of the eyes. Most studies manifested that the right hemisphere is responsible for the aggression, fear, and detection of predators and other threats, and the left hemisphere is responsible for the positive emotions, food search, and detection of large changes in the environment. Nevertheless, some independent studies manifested the opposite biases in the same behaviour tasks. To evaluate the value of species, behaviour task, locomotion type and breeding status in visual lateralisation biases we studied the behaviour of swimming and flying Whooper swans and Bewick's swans with and without chicks when observing a source of danger and a partner. We found that in the same conditions, the visual lateralisation bias was identical in two species and it differed depending on the type of locomotion in one species. Birds had a significant bias in the observation of the source of disturbance and hadn't in the observation of the leading partner. The presence of chicks strengthened the manifestation of visual lateralisation in the following birds. Therefore, special attention should be paid to details in comparing the results of studies conducted under different circumstances.

“…This may indicate that the left eye (right hemisphere) use provides an advantage in the assessment of potential threat (Blumstein et al, 2018). Similarly, white-fronted geese seem to show improved recognition of potential threats when monitoring them with the left eye (Zaynagutdinova et al, 2020). Our results do not suggest that the use of the left or right eye affects the speed of assessment of a potential threat in steppe marmots.…”

A variety of vertebrate species display lateralization of visual perception of threat. However, the vast majority of studies were carried out in the laboratory conditions, and little is known about the relevance of this lateralization for animals in their natural environment. The aim of our work was to study lateralized visual perception of potential threat in the steppe marmot. The asymmetric use of visual fields when reacting to an approaching threat was assessed in two wild populations of marmots. The results showed that marmots predominantly used the right eye for threat monitoring. A significant impact of anthropogenic disturbance was found both within and between the populations. The right-sided preference was reduced in animals inhabiting areas with high degree of anthropogenic disturbance. The eye (left/right) a focal individual used for threat monitoring did not influence its flight initiation distance. Contrary to a previous study, our results do not suggest that the use of a particular eye affects the speed of threat assessment.

“…The right hemisphere advantage was found, for example, in antipredator responses (e.g., Lippolis et al 2005 ) and the perception of fearful social cues ( Siniscalchi et al 2018 ). Among birds, the geese which were closer to the source of anthropogenic disturbance (a trafficked road) were found to be more prone to use the left eye ( Zaynagutdinova et al 2020 ). Thus, the right hemisphere is responsible for the control of both emergency and social responses probably because of the involvement of the same cognitive abilities e.g., continuous attention and high reactivity.…”

Lateralization in monogamous pairs: wild geese prefer to keep their partner in the left hemifield except when disturbed

Behavioural lateralization, which reflects the functional specializations of the two brain hemispheres, is assumed to play an important role in cooperative intraspecific interactions. However, there are few studies focused on the lateralization in cooperative behaviours of individuals, especially in a natural setting. In the present study, we investigated lateralized spatial interactions between the partners in life-long monogamous pairs. The male-female pairs of two geese species (barnacle, Branta leucopsis, and white-fronted, Anser albifrons geese), were observed during different stages of the annual cycle in a variety of conditions. In geese flocks, we recorded which visual hemifield (left/right) the following partner used to monitor the leading partner relevant to the type of behaviour and the disturbance factors. In a significant majority of pairs, the following bird viewed the leading partner with the left eye during routine behaviours such as resting and feeding in undisturbed conditions. This behavioural lateralization, implicating the right hemisphere processing, was consistent across the different aggregation sites and years of the study. In contrast, no significant bias was found in a variety of geese behaviours associated with enhanced disturbance (when alert on water, flying or fleeing away when disturbed, feeding during the hunting period, in urban area feeding and during moulting). We hypothesize that the increased demands for right hemisphere processing to deal with stressful and emergency situations may interfere with the manifestation of lateralization in social interactions.
