A comparative perspective on the evolution of mammalian reactions to dead conspecifics
In a variety of mammalian species, mothers and others care for and/or carry deceased newborns, and sometimes other conspecifics. The rationale for such behavior remains elusive. Based upon field observations of olive baboon (Papio anubis), African elephant (Loxodonta africana), and Thornicroft’s giraffe (Giraffa camelopardalis) responses to recently dead conspecifics, combined with reports in the literature, […]
Nighttime Suckling Behavior in Captive Giraffe (Giraffa camelopardalis reticulata)
Suckling behaviors are useful to better understand mother–offspring relationships. However, in many species, knowledge about nighttime suckling behavior is sparse. In the present study, we investigated suckling behavior in four calves of the reticulated giraffe (Giraffa camelopardalis reticulata) and their mother in the Kyoto City Zoo, Japan, by analyzing video clips of 9614 h. The […]
How social relationships of female giraffe (Giraffa camelopardalis tippelskirchi) change after calving
Giraffe (Giraffa camelopardalis) social structure is described as a fission–fusion society (Bercovitch & Berry, 2009; Shorrocks & Croft, 2009), wherein mother–daughter pairs and specific adult female dyads form strong, continuous social relationships (Bercovitch & Berry, 2013; Carter et al., 2013). Bercovitch & Berry (2013) found that in addition to related individuals, peers are more likely […]
Social Behavior and communication in a herd of captive giraffe
Data on wild giraffe herds have often been interpreted as a random association of individuals, but the extent to which giraffe have a more complex social structure may have been overlooked. The focus of this dissertation is to investigate patterns of social relationships among individual giraffe. Social interaction and association (proximity and nearest neighbor) distributions […]
Mother-young relationships in captive ungulates: variability and clustering
We recorded four measures of mother-young association and the percentage of time the young spent lying during the first week after birth for 59 mother-young pairs belonging to 22 species and seven families of ungulates. The measures of mother-young association were positively correlated with each other and negatively correlated with the percentage of time the […]
Current knowledge about the social organisation of giraffes
The Etosha Giraffe Research project in Namibia focuses on the social relationships among giraffes, which have previously been described as having little social structure nor strong bonds between individuals (Dagg and Foster, 1976; Le Pendu et al., 2000; Moss, 1976). Giraffes live in a fission-fusion society characterised by frequent changes of associates, with males adopting […]
Giraffe mother–calf relationships in the miombo woodland of Katavi National Park, Tanzania
Both predator pressure and habitat type influence mother–offspring relationship. Giraffe’s herd size and herd composition can be influenced by these two environmental factors. We sought to uncover whether predator pressure and habitat type also have an impact on giraffe mother–calf proximity and time spent together. We studied giraffe mother–calf relationships to compare mother–calf dyadic relationships […]
Giraffe Social Behaviour
Many features recommend the giraffe (Giraffa camelopardalis) for behavioural study: it is big, abundant, conspicuous, active by day, reasonably trusting of people, deliberate, and the best self-marked animal in existence. Surprisingly, its social behaviour has been largely neglected. We studied giraffe exclusively for the following periods: February–March, 1975 and January–December, 1977 in the Serengeti National […]
Developing models for mother–infant behaviour in Black rhinoceros and Reticulated giraffe (Diceros bicornis michaeli and Giraffa camelopardalis reticulata) at Brookfield Zoo, Illinois
For over a decade the behaviours of mothers and newborn calves of Black rhinoceros Diceros bicornis michaeli and Reticulated giraffe Giraffa camelopardalis reticulata have been observed at Brookfield Zoo during the critical first few weeks post-partum. Consistent patterns were seen for individuals within species, allowing models of time budgets, including ranges of variability surrounding each […]
Giraffe mothers in East Africa linger for days near the remains of their dead calves
Repeated investigation of dead young or carrying of corpses has been observed in several mammalian taxa, notably primates [e.g. yellow baboons (Papio cynocephalus): Altmann, 1980; chimpanzees (Pan troglodytes): Goodall, 1986; Matsuzawa, 1997; Biro et al., 2010; ring-tailed lemurs (Lemur catta): Nakamichi, Koyama & Jolly, 1996; Yunnan snub-nosed monkeys (Rhinopithecus bieti): Li et al., 2012), dolphins […]
