Comparative feeding behaviour and food preferences of oxpeckers (Buphagus erythrorhynchus and B. africanus) in captivity.
The feeding methods, activities and behaviour of red-billed and yellow-billed oxpeckers in captivity were compared. Both species were found to be very similar with regard to feeding. The differences observed were a greater dependence on ectoparasites such as flies and larger ticks (Amblyomma hebraeum) and a higher food intake for the yellow-billed oxpecker. These differences are the result of t...
متن کاملMutualism or parasitism? Using a phylogenetic approach to characterize the oxpecker-ungulate relationship.
With their striking predilection for perching on African ungulates and eating their ticks, yellow-billed (Buphagus africanus) and red-billed oxpeckers (B. erythrorhynchus) represent one of the few potentially mutualistic relationships among vertebrates. The nature of the oxpecker-ungulate relationship remains uncertain, however, because oxpeckers are known to consume ungulate tissues, suggestin...
متن کاملRed-billed oxpeckers: vampires or tickbirds?
Many recent studies have shown that classic examples of mutualism are either far more complicated than originally believed, or that they are not mutualisms at all. Red-billed oxpeckers (Buphagus erythrorhynchus) are just such an example of an ‘‘adaptive story.’’ These small birds feed almost exclusively on what they can glean from the skin of large African mammals. The relationship is obligate ...
متن کاملRe‐establishing the pecking order: Niche models reliably predict suitable habitats for the reintroduction of red‐billed oxpeckers
Distributions of avian mutualists are affected by changes in biotic interactions and environmental conditions driven directly/indirectly by human actions. The range contraction of red-billed oxpeckers (Buphagus erythrorhynchus) in South Africa is partly a result of the widespread use of acaracides (i.e., mainly cattle dips), toxic to both ticks and oxpeckers. We predicted the habitat suitabilit...
متن کاملParafilariosis in African buffaloes (Syncerus caffer).
This is the first report on the occurrence of Parafilaria bassoni in the African buffalo (Syncerus caffer). Previously this parasite has been recorded only in springbok (Antidorcas marsupialis) in Namibia. Haemorrhagic perforations (bleeding points), the usual lesions seen in infected animals, were caused by gravid female parasites ovipositing embryonated eggs. These lesions occurred mainly on ...
