This hawk is associated with cattle because of its behavior of climbing on the back of the cattle in search for ticks and other ectoparasites. It also displays this behavior toward capybaras. Sometimes it hurts the cattle taking pieces of meat out of the wounds. It is very common in man-modified areas.
