Oxpeckers are endemic to sub-Saharan Africa, in open habitats, but are absent from the driest deserts and the rainforests. They graze exclusively on the bodies of large mammals, feeding on ectoparasites, particularly ticks, as well as on insects infesting wounds present in their hosts. The impala is their preferred host, probably because of their heavy tick load as well as the social nature of that species. Can you spot the oxpeckers in these images?
