The White-chinned Petrel is a large, often numerous petrel of the Southern Ocean. It closely resembles the other petrels in the genus Procellaria, but the large size, dark plumage, typically white chin, and large, pale bill of this species are distinctive. It breeds on various subantarctic islands, including South Georgia and the Falkland Islands. Non-breeding birds disperse widely across the Southern Ocean, moving north as far as the Humboldt Current off Peru and waters off northern Argentina. This species nests colonially in burrows on vegetated slopes or flat, poorly-drained terrain. Feeding birds gather in groups and often follow ships offshore.
