Species notes
Overview
Note the gray face, chin, and throat and the stout bill. Wings long and narrow. Other dark gadfly petrels are rare off the New Zealand mainland but the similar Providence and dark-morph Kermadec Petrels have white patches on the underwing; the latter also lacks any gray on its face. The rarely-seen Kerguelen Petrel is smaller, with a shorter bill and a pale edge on the underwing.
Behavior
Forages at sea and returns after dark to burrows at coastal breeding colonies, where it gives loud repeated calls.
