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.

Pycroft petrel is grey and white; the upperparts are grey (with a darker M pattern on the back) and the underparts and forehead are white. It has a faint grey band across the breast and a dark grey patch around the eye.

Little is known about its diet, but it is known to eat squid and crustaceans. Outside the breeding season it is thought to feed in the
Central Pacific, and has been recorded as far as

Red List. Efforts to remove rats and other introduced predators from their breeding colonies have resulted in a recovery for this species, and its numbers are now increasing.
