Social influences on vigilance behaviour in giraffes, Giraffa camelopardalis

Vigilance in ungulates is considered to have a predominantly antipredator function, with the frequency and duration of scans per individual decreasing with increasing group size. Social influences on vigilance scans have been overlooked in studies on ungulates, although studies in primates and birds show that conspecific scans are important determinants of vigilance behaviour. We investigated […]

Giraffe cow reaction to the death of her newborn calf

Observations in their natural habitat of animals’ reactions to recently deceased conspecifics are rare. Documenting a diversity of mammalian responses is essential to augment our understanding of potential evolutionary foundations of both mental states and social bonds. Individuals that previously had strong social ties to dead conspecifics might be expected to display different reactions than […]
