Wikipedia Abstract

The mottled petrel (Pterodroma inexpectata) or kōrure is a species of seabird and a member of the gadfly petrels. The bird is 33–35 cm in size, with a 74–82 cm wingspan. This species is highly pelagic, rarely approaching land, except to nest and rear young. The mottled petrel feeds mostly on 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.
