The Chilean Skua (Stercorarius chilensis) is a large predatory seabird that occurs in Argentina and Chile, but ranges as far north as Brazil and Peru when not breeding.
It is known to hybridize with the Brown Skua in southern Argentina.
It has a dark cap that contrasts with its cinnamon throat and lower face.
The Chilean Skua is very aggressive towards other seabirds and will attack and hunt them. They eat offal (= entrails and internal organs of butchered animals), rodents and carrion.
