Have you ever seen birds such as cattle egrets or oxpeckers perched on the backs of antelope, cows, giraffes, or oxen, pecking at their skin?
Pernahkah Anda melihat burung seperti kuntul kerbau atau jalak - pelatuk - kerbau bertengger di punggung antelop, sapi, jerapah, atau lembu, dan mematuki kulit mereka?
