This species is highly pelagic, rarely approaching land, except to nest and rear young. The Mottled Petrel feeds on mostly fish and squid, with some crustaceans taken. It is a transequatorial migrant, breeding in New Zealand and some of the lesser islands, then moving to the Bering Sea, concentrating in the Gulf of Alaska and the Aleutian Islands.
The Scaled petrel is classified as Near Threatened (NT), is close to qualifying for or is likely to qualify for a threatened category in the near future.
