In farming areas, the Crested Caracara sometimes attacks newborn lambs. On one occasion, I saw a caracara, together with a few Black Vultures, aggressively approaching a sheep that had just given birth; I had to intervene and chase the birds away.

The Crested Caracara is considered a nuisance by many farmers. He is not threatened by extinction, though, probably because most locals believe that he is not edible (but I heard of one exception).
