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 dependance 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 the larger size, limited choice of host
animals and closer host/oxpecker relationship of the yellow-billed oxpecker.
