Petrel Carigrís Pterodroma gouldi

A large, all-dark gadfly petrel found across the Tasman Sea and the temperate and subtropical southwest Pacific Ocean. Note the gray face, chin, and throat and the stout bill. Wings long and narrow. In New Zealand, breeds on offshore islands off the North Island as well as on some mainland cliffs and headlands near the sea. Gives an “o-hi” or “o-hoe” call when flying above breeding areas or a loud “si-si-si” when on land or in burrows. 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.
