Grey-faced Petrel

Pterodroma gouldi (Hutton, FW, 1869)

Grey-faced Petrel, Pterodroma gouldi, breeds on islets off the north of New Zealand’s North Island and ranges after breeding to the Tasman Sea off south-eastern Australia and the Chatham Rise east of New Zealand. It is a petrel of the family Procellariidae and was described by Hutton in 1869. The species is confined to the north of the North Island, with colonies mainly on offshore islands. It was once treated as part of the great-winged petrel, but has been recognised as separate since 2014. In New Zealand it is also called ōi and muttonbird.
