The behaviour of giraffe giraffa camelopardalis in the eastern transvaal

The giraffe in South Africa live entirely in the Eastern Transvaal, a lowveld region primarily of grass or veld with scattered bushes and low trees. The giraffe browse on a wide variety of trees in the spring and fall when few leaves are available, but in summer when all the trees are in foliage they are much more selective. The giraffe spend most of the day and part of the night feeding, especially the early morning and late afternoon. In

Notes on the reproduction of Baringo giraffe

Koga (Kagaku Oaho, 27, 1938) reported on the birth of a Nigerian giraffe, female, Giraffa camelopardalis peralta at the Ueno Zoo at 7:24 pm. Parturition time was reported to be three hours, nineteen minutes. The calf gained its feet at 7:56 pm, 32 minutes after birth, though it did not eat for 42 hours.

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

Feasibility of characterizing reproductive events in large nondomestic species by transrectal ultrasonic imaging

The feasibility of using transrectal ultrasonography for imaging the in situ morphology of the reproductive tract of females of several large nondomestic and endangered species was studied. Two black (Diceros bicornis) and 1 white (Diceros simus) rhinoceros, 2 Asian (Elaphus maximus) and 2 African (Loxodonta africana) elephants, 4 banteng (Bos javanicus), 1 gaur (Bos taurus), 1 giraffe (Giraffa camelopardalis), and 1 bactrian camel (Camelus bactrianus) were examined. Real-time ultrasonic images were obtained for the following structures: 1) rhinoceros—corpus luteum, ovarian

The impacts of elephant, giraffe and fire upon the Acacia tortilis woodlands of the Serengeti

The reduction in canopy cover of the Seronera woodlands since the mid- 1960s can be largely attributed to the destruction of mature Acacia tortilis trees by elephants. The development of the tree regeneration that has colonized the gaps in the mature canopy is being suppressed by giraffe browsing and periodic burning. A simple model is presented which simulates these impacts upon the dynamics of the A. tortilis population. Height-specific impact rates of these three agents are quantified. Between 1968 and

The giraffe and its food resource in the Serengeti

The dynamics of the giraffe population of the Serengeti were quantified to ascertain the response of the population to the increasing biomass of the available browse resource. Aerial counts conducted in 1971 and 1976 together with analyses of fecundity and mortality data suggest a rate of population increase of some 5–6% per annum. Compared with the dynamics of a stable giraffe population in Nairobi National Park, the sub-adult components of the Serengeti regional populations are larger and juvenile growth rates

Population statistics and carrying capacity of large ungulates in Whovi Wild Area, Rhodes Matopos National Park, Zimbabwe Rhodesia

Population data for introduced large ungulates, are presented to demonstrate population growth in terms of numbers and biomass in the Whovi Wild Area of the Rhodes Matopos National Park, Zimbabwe Rhodesia. Peak calving in relation to food requirements of different species is discussed. Standing crop of large ungulates was calculated and compared with carrying capacity as predicted by Coe et al. (1976)

Perinatal maternal and neonatal behaviour in the captive reticulated giraffe

A captive reticulated giraffe was observed constantly for three weeks prior to, and periodically for 90 days subsequent to, the birth of her calf. Extensive observations were made of the birth sequence, feeding, drinking, sleeping and one instance of an infant distress call, as well as observations of the initiation of maternal behaviour (including licking, nursing, placentophagia, and what appeared to be helping the calf to stand, guiding the calf’s movements, and attempts to respond to the calf’s distress call).

Food habits of giraffe in Tsavo National Park, Kenya

In the context of a broader ecological investigation, food habits of giraffe were studied in Tsavo National Park (East). The only method employed was direct observation of feeding animals in the field. Each instance in which one animal fed on one individual plant was counted as one food record for this plant species; 4025 records are analysed. A total of sixty-six plant species was found to be eaten, the great majority being trees and shrubs, with a few creepers and
