Cook’s Petrel
Cook's Petrel
Pterodroma cookii
At a Glance
Breeding on islands around New Zealand, this petrel ranges over vast distances in the Pacific Ocean. Since the late 1970s, research cruises have revealed that Cook's Petrel occurs regularly off our west coast -- but so far offshore that it is seldom seen on ordinary one-day birding boat trips, let alone from shore.
