Grey-faced petrel

Pterodroma macroptera gouldi

The grey-faced petrel is the subspecies of great-winged petrel that breeds in New Zealand. It breeds in numerous places around North Island. The breeding population is estimated at between 200,000 and 300,000 pairs. Being mostly dark in colour, it may be confused with the black petrel and the flesh-footed shearwater at sea.
