The Kermadec petrel, known scientifically as Pterodroma neglecta, is a member of the gadfly petrel family Procellariidae. This bird is a medium-sized petrel, measuring approximately 38 cm in length with an impressive wingspan reaching 100 cm. It exhibits polymorphism, displaying a variety of plumage morphs including light, dark, and intermediate forms.
When observing the Kermadec petrel, look for its distinctive size and wingspan. The polymorphic nature of its plumage can make identification challenging, but the variations in coloration among individuals are a key characteristic to note.
The Kermadec petrel is an oceanic bird, spending much of its life at sea. It comes to land only to breed, favoring remote islands for nesting.
This species has a breeding range that spans the Pacific Ocean, from Lord Howe Island to the Juan Fernández Islands. A small colony exists on Balls Pyramid, west of Lord Howe Island, with less than 100 individuals. The bird is also known to breed on Round Island, off Mauritius. Vagrant sightings have been reported in locations such as Hawaii, Australia, New Zealand, and even as far afield as the United Kingdom and the United States, though these are considered dubious.
The Kermadec petrel is monogamous, typically raising a single chick each year. It is known for its wide range of breeding times, which vary among different colonies.
Breeding patterns for the Kermadec petrel are not uniform across its range. Nesting may occur from October to February or from February to March, depending on the colony. The chick becomes independent after a period of 100–130 days.
The diet of the Kermadec petrel consists of marine creatures such as squid and fish, which it catches from the ocean's surface.
The Kermadec petrel is currently classified as Least Concern on the IUCN Red List, indicating that it is not at immediate risk of widespread decline.
