About These Birds

New Caledonian Storm-petrel

New Caledonian Storm-petrel, 18–20 cm, is an extremely poorly known species recorded only from around New Caledonia in the southwest Pacific. Until recently unconfirmed as a breeding species; a small colony was found in 2021. Morphology similar to Black-bellied Storm-petrel; conservation status under review.

Polynesian Storm-petrel

Polynesian Storm-petrel, 25–26 cm, is the largest storm-petrel, breeding on tropical Pacific islands from the Marquesas to the Cook Islands. Two morphs: dark and white-bellied. Flies with distinctive high bounding style. Vulnerable; predated by introduced rats and cats on nesting islands. Planktivore.
