“…Lateralized behaviour at the population level, in which individuals within the population share a preference for the same side, is not limited to humans, and in fact exists in many vertebrate species [2]. For example, reindeer herds tend to circle in a counter-clockwise direction [3], and giraffes move their left leg first when beginning a splay stance [4]. Lateralization for limb preference can be found in a wide range of species, including lions, bats, toads, parrots and chickens [5].…”

Behavioural laterality in foraging bottlenose dolphins ( Tursiops truncatus )

Lateralized behaviour is found in humans and a wide variety of other species. At a population level, lateralization of behaviour suggests hemispheric specialization may underlie this behaviour. As in other cetaceans, dolphins exhibit a strong right-side bias in foraging behaviour. Common bottlenose dolphins in The Bahamas use a foraging technique termed ‘crater feeding’, in which they swim slowly along the ocean floor, scanning the substrate using echolocation, and then bury their rostrums into the sand to obtain prey. The bottlenose dolphins off Bimini, The Bahamas, frequently execute a sharp turn before burying their rostrums in the sand. Based on data collected from 2012 to 2018, we report a significant right-side (left turn) bias in these dolphins. Out of 709 turns recorded from at least 27 different individuals, 99.44% (n = 705) were to the left (right side and right eye down) [z = 3.275, p = 0.001]. Only one individual turned right (left side and left eye down, 4/4 turns). We hypothesize that this right-side bias may be due in part to the possible laterization of echolocation production mechanisms, the dolphins' use of the right set of phonic lips to produce echolocation clicks, and a right eye (left hemisphere) advantage in visual discrimination and visuospatial processing.

“…The few deviations from the preferred side were observed when mature males (A2 and A4) sparred with the youngest subadult male (C2) such that the large disparity in body size might have contributed to the discrepancies. A previous study by Svoke (2017) examined lateralisation in splay posture in male giraffes and showed a moderate tendency of individuals to place their left leg first when splaying to drink, though the three captive individuals in this study varied greatly in their degree of lateralisation.…”

Sparring dynamics and individual laterality in male South African giraffes

Sparring by male giraffes has been commonly reported since its first description in 1958 and is believed to play a role in establishing male dominance hierarchies. However, despite being often documented, quantitative investigations of sparring behaviour are currently lacking. Here, we investigate the factors affecting the frequency, duration and intensity of sparring bouts in a population of giraffes Giraffa camelopardalis giraffa living on a private fenced reserve in Limpopo, South Africa. We show that sparring bouts were most frequently observed in young adults, and between males that were more evenly matched in size. Sparring bouts between males of similar body size were also characterised by being of high intensity and of short duration. Taken together, these results support the suggestion that sparring functions principally to provide maturing males a means of testing their competitive ability without escalating to full‐scale fights. Additionally, mature bulls intervened on young adults possibly to disable any winner effect achieved by the latter, with the most dominant bull being responsible for the majority of interventions. For the first time, we also show that individuals displayed strong laterality when engaged in sparring: individuals consistently preferred delivering blows from either their left or right side, and these preferences dictated the orientation of sparring bouts (whether head‐to‐head or head‐to‐tail). Lastly, we show that sparring displayed a seasonal peak which coincided with the onset of the wet season and possibly reflected the increased aggregation of males at this time. A more nuanced understanding of how social and environmental factors shape interactions among individuals, such as sparring, will improve our understanding and management of this charismatic animal.

“…Motor laterality has been often studied in non-human animals, including ungulates [1][2][3] . These studies have relied on the use of different scenarios, including leg positions while standing or resting, leg movement associated with locomotion, grazing/foraging behavior, contest, splaying, and suckling behavior, as well as unrestricted food handling [4][5][6] . It has been noted that adult animals tend to be ambidextrous although the side preferences can change with experience 3 .…”

Motor laterality has been often studied in non-human animals, including ungulates, and it has been noted that adult animals tend to be ambidextrous. Therefore, the current study aimed to study the laterality of grazing posture when standing in a quadrupedal position. To this end, a total of 106 horses (24 foals, 8 yearlings, 14 subadults and 60 adults 53 females and 7 males) of Pyrenean horse from 11 grazing areas farms were observed and their forelimb preference when grazing was recorded (1-3 times for each animal). The obtained results revealed that approximately half of the horses were right-handed and half left-handed, and females were equally lateralized than males. Moreover, lateralization was not affected by age. Therefore, it seems that forelimb ambidexterity in Pyrenean horses is probably due to the lack of human contact. As the presentation of unevenness may be crucial to orthopaedic health and the compensatory mechanisms used by uneven footed horses are currently unknown, data presented here have a complementary crucial interest.
