Guineafowl are particularly well-suited to consuming massive quantities of ticks, which might otherwise spread lyme disease. Males often show aggression towards each other, and will partake in aggressive fighting which may leave other males bloodied and otherwise injured. They will attempt to make themselves look more fearsome by raising their wings upwards from their sides and bristling their feathers across the length of the body, and they may also rush towards their opponent with a gaping beak.
