Chilean skua

The Chilean skua, also called the cinnamon skua (Stercorarius chilensis), is a large predatory seabird, which breeds in Argentina and Chile, but ranges as far north as Brazil and Peru when not breeding. A relatively distinctive skua, it has a dark cap that contrasts with its cinnamon throat and lower face. Hybrids with the Falkland skua are known from southern Argentina.

Chilean skuas feed on fish and other seabirds, as well as scraps, and carrion. They breed in colonies during the Southern Hemisphere summer.

Overall, little is known about this South American species and what is known largely comes from descriptive studies scattered through time and concentrated at a few select breeding colonies.
