This strictly pelagic species inhabits the open ocean for most of its life, returning solely to remote, forested offshore islands of New Zealand for breeding, nesting in burrows beneath dense vegetation.
Primarily consumes small squid, crustaceans, and small fish, which it obtains by surface-seizing or shallow plunging into the water.
Pycroft's Petrels exhibit a fascinating dichotomy in their daily activity: they are strictly nocturnal on their breeding islands to evade aerial predators, while remaining diurnal during their vast pelagic existence. At sea, they are solitary or found in loose aggregations, tirelessly patrolling ...
The Pycroft's Petrel is an endemic breeder to a very restricted number of offshore islands in New Zealand, predominantly Stephenson Island, Poor Knights Islands, and the Hen and Chickens Islands, all situated off the North Island. After the breeding season, typically from November to May, these p...
