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.

The present distribution and status of the giraffe in west Africa

Several papers have been published in Mammalia in the last few years on the distribution of the West African giraffe, Giraffa camelopardalis paralta Thomas 1898. However, its exact distribution and numbers are still uncertain; this paper records some recent information on the subject and suggests reasons for the limited numbers at the present time. Another subspecies, antiquorum, is found in Kordofan and Darfur further to the east. Malbrant (1952) records that the giraffe east of the Chari river are similar

Horns and other bony structures of the skull of the giraffe, and their functional significance

The gross morphology of the giraffe skull and its superficial anatomy is described. The parietal, median, occipital, orbital, azygous horns and other exostoses are described. The giraffe’s peculiar mode of intra-specific fighting is explained and the features of the giraffe’s skull are related to this. It is concluded that the skull of the male giraffe is highly specialised for its particular mode of fighting. The male differs in this respect from the female whose skull is not so developed and

Circulation of the Giraffe

The long neck of the giraffe presents a unique problem in the regulation of the systemic arterial blood pressure and in the maintenance of the cerebral circulation. In 1954, Goetz and Budtz-Olsen succeeded in measuring the arterial blood pressure in a standing, unanesthetized giraffe. In this animal, approximately 13 feet tall, the carotid artery mean pressure was found to be 200 mm. Hg at the base of the brain. The present study was undertaken 2 years later as a sequel

Giraffe Intergradation in Kenya

Since data concerning the distribution of the species and races of giraffe are scarce, the following observation, which concerns apparent hybrids between the reticulated giraffe (Giraffa camelopardalis reticulata) and the Masai giraffe (G. capensis tippelskirchi), a race of the southern species, seems noteworthy. The reticulated giraffe inhibits such low-level deserts in Kenya as lie north of the Tana River and east of Lake Rudolph, and also adjacent parts of southern Abyssinia; while the Masai giraffe occurs in deserts, bush country
