context_page_description: Pycroft's petrel is a species of seabird in the petrel and shearwater family Procellariidae.
context_section_description: The species only breeds in New Zealand, nesting on 11 islands off North Island. Breeding colonies are found on Stephenson Island, the Poor Knights Islands, Hen and Chickens Islands, and Mercury Islands. It used to also breed on Norfolk Island and Lord Howe Island, but have become extinct there.
  The breeding season begins in October when birds return to their colony; laying is synchronised and happens between 21 November and 10 December. This species lays a single egg in a burrow. The nesting burrows are 30 to 130 cm (12–51 in) long and the nesting chamber is lined with leaves. Both parents incubate the egg, with the male taking the first shift. This first incubation shift lasts 10–14 days. Chicks hatch 45 days after laying. Chicks leave the nest in around 80 days after hatching, and are not fed for the last week they are in the nest.
