Seabirds around fishing vessels

Grey petrel

Procellaria cinerea

The grey petrel is distributed around the subantarctic region, but mainly breeds in the New Zealand region. The largest breeding population occurs on Antipodes Island (around 50,000 breeding pairs annually). This species is easily distinguishable from other Procellaria petrels, and is unlikely to be misidentified.
