The Bonin Petrel is a medium-sized gadfly petrel with grey upperparts and white underparts, breeding on islands in the Northwest Pacific. It is a nocturnal breeder.
Where to spot
Breeds on islands in the Northwest Pacific, primarily the Northwestern Hawaiian Islands (e.g., Midway, Laysan) and Bonin Islands (Japan). Forages widely across the North Pacific.
How to spot
Look for its grey upperparts with a dark 'M' pattern, white underparts, and a dark cap. Its flight is swift and arcing. Best observed during pelagic trips in the Northwest Pacific, especially around the Hawaiian Islands.
When to spot
Breeding occurs during the northern winter (November-May). Can be observed at sea during the non-breeding season in the central and western North Pacific.

This petrel constructs deep burrows for nesting, sometimes over 2 meters long, to protect its single egg from predators and the harsh island environment.
