Social organization and behaviour of giraffe in Tsavo East National Park

Social organization and behaviour of giraffes were studied in Tsavo East National Park, Kenya, by means of road strip counts and observations of individually known animals. Most groups comprised of one to ten animals, with a maximum of thirty‐five and a mean of 3.8. Group size and composition varied locally to some extent. Single adult males constituted the commonest group type; in groups of two or more animals the sexes were usually mixed. Groups were loose and open; close inter‐individual

Gazing at a giraffe gyroscope: where are we going?

Giraffe are popular animals to watch while on wildlife safaris, and feature prominently in zoos, advertisements, toys and cartoons. Yet, until recently, few field studies have focused on giraffe. We introduce this giraffe topic issue with a review essay that explores five primary questions: How many (sub) species of giraffe exist? What are the dynamics of giraffe herds? How do giraffe communicate? What is the role of sexual selection in giraffe reproduction? How many giraffe reside in Africa? A confluence

"Necking" behaviour in the giraffe

Previous references to “necking” behaviour, and the main features of the study area are briefly outlined. “Necking” behaviour in giraffe takes place only in all male herds. When the animals are in a head to head posture the intensity is either high or low, but when animals take up a head to tail posture the actions are always of high intensity and appear to have greater sexual significance. The significance of “necking” is discussed, and it is suggested that these

On comparing the behaviour of zoo housed animals with wild conspecifics as a welfare indicator, using the giraffe (Giraffa camelopardalis) as a model

To assess the validity of using wild behavioral data as a welfare indicator for zoo animals, the time budgets of 19 captive giraffe (Giraffa camelopardalis), from four zoos were compared with the time budgets of wild giraffe from Hwange National Park, Zimbabwe. Differences were shown to exist between the behavior of wild and captive giraffe. However, only the duration of lying differed significantly across zoos. Correlations demonstrated that both enclosure size and feed restriction affected the locomotor activity of the

The effect of translocation on the Rothschild’s giraffes

In July 1977, twenty one Rothschild’s giraffes (Giraffa camelopardalis rothschildi LYDEKKER) were trans-located by the Kenya Game Department from Lewa Downs Farm, Soy to Nakuru National Park. The objective of the translocation was to accord the  giraffes and opportunity to establish themselves in a protected environment. The research described in this thesis was carried out between August 1978 and July 1979 in both Nakuru National Park and Lewa Downs Farm, Soy. The aim of this study was to compare selected

Feeding habits of spotted hyaenas in a woodland habitat

The feeding habits of spotted hyaenas were recorded during a 2-year full-time study in the Lowveld of South Africa. The animals were observed for 335 h at night using artificial light. These results were supplemented by the analysis of 200 regurgitations and 527 scats collected on a monthly basis over 12 months, with a consideration of the availability of different prey species. It is argued that regurgitation gets rid of any excess of hair, the remainder in the scats giving

The reaction of a group of Rothschild’s giraffe to a new environment

The behaviour of a translocated group of 11 Rothschild’s giraffe (Giraffa camelopardalis rothschildi Lydekker) was studied for 9 weeks in 1968. A comparison was made between their new and former habitats, the food plants eaten in both places, and behaviour. For 3.5 months after release, they appeared to have settled in the area, but they suddenly started extending their range. Possible reasons are suggested for their failure to stay in the release area and their eventual disappearance.
