Oxpeckers are annoying, looking for dead skin, open wounds, etc. Experiment done = divided a small herd of cattle into 2 groups, one with oxpeckers one without. Did it for a month, then switched it 3 times and shuffled the cattle. Experiments show that there is no effect of ticks with this experiment. However, for open wounds, weeks found that ox with open wounds who were exposed to oxpeckers had many more open wounds than those protected from the birds.
