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 relation between a calf’s age and the mean duration and frequency of suckling were consistent with the results of previous daytime studies: the longest duration

Giraffe nursing behaviour reflects environmental conditions

Nursing behaviour is one component of mammalian life history strategy that demonstrates context-dependent flexibility within species. Wild giraffes live in groups and feed themselves over large area. In the zoo, giraffes are kept in enclosures with abundant food resources.We aimed to analyse whether the nursing behaviour of giraffes differs between the zoo and nature reserve and discuss which factor (food intake, presence of predators, population density) can explain the difference. We observed seven and four female–calf pairs in the Bandia
