A long-winged, deeply forked-tailed seabird, males glossy black with a small white axillary patch, riding thermals for hours with barely a wingbeat.
Occasionally seen soaring over Borneo's coastal waters, often harassing boobies and terns in flight to steal their catches rather than diving for food itself.
