Distribution and population
The Brown Skua is found on the Antarctic Peninsula and subantarctic islands of the Atlantic, Indian and Pacific Oceans, wintering near or slightly dispersed from the breeding area (del Hoyo et al. 1996).
This marine species is found on or around subantarctic islands populated by burrow-nesting seabirds or penguins. It is highly predatory, feeding mainly on other birds but will also scavenge around fishing boats and ships and feed at sea. Breeding begins in October and November. Birds are loosely colonial but highly territorial, nesting on grass, gravel or bare rock. Individuals at some northern colonies are resident throughout the year, but will disperse over the sea where conditions are harsher (del Hoyo et al. 1996).
