A dark, fork-tailed storm-petrel that flutters low over the waves, distinguished from similar species mainly by subtle wing and rump patterning.
Classed as Near-threatened due to a small number of breeding colonies and vulnerability to introduced predators, with wandering birds occasionally passing through Bornean waters on migration.
