Giraffe bed and breakfast: Camera traps reveal Tanzanian yellow-billed oxpeckers roosting on their large mammalian hosts

Oxpeckers are obligate mammal gleaners, feeding on ectoparasites and dead skin of large herbivores (Bezuidenhout & Stutterheim, 1980; Dean & MacDonald, 1981). There are two sympatric species in sub-Saharan Africa: the red-billed (Buphagus erythrorhynus) and yellow-billed oxpeckers (Buphagus africana). The red-billed species is smaller, with a scissor-like bill, while the yellow-billed species is larger, behaviourally dominant, and has a broad, flat beak (Attwell, 1966; Neweklowsky, 1974; Stutterheim, Bezuidenhout, & Elliott, 1988). These behavioural and morphological attributes are hypothesized to contribute

The applicability of lion prey selection models to smaller game reserves in South Africa

Prey selection by lions (Panthera leo) reintroduced into small game reserves (typically <1000 km2) in South Africa was compared with results from larger (more naturally functioning) protected areas. Prey selection was used to calculate mean preference indices, and where sample size allowed, tested for significance of preference, as well as for comparisons with current estimates in the literature. The model by Hayward & Kerley (2005) was found to be 85% accurate, suggesting it is well suited as a predictive tool

Interactions between large African browsers and thorny Acacia on a wildlife ranch in Kenya

Some plants respond to browsing with compensatory regrowth of plant tissues and with increased thorn growth. Associations between browsers and their preferred forage were examined through wandering quarter vegetation sampling and observational studies in an effort to understand how some plants respond to browsing by large African herbivores. Acacia seyal (n = 2680) A. drepanolobium (n = 1850), and Balanites glabra (n = 960) were three species of frequently browsed indigenous plants examined on Game Ranching Ltd. in Kenya. There

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)
