ID tip
Grey-faced petrels are large birds, with a body length of 42–45 cm and weighing on average 550 grams (19 oz). They have a dark black-brown colouration, similar to that of the black-footed albatross, with a black bill and pale grey to buff feathers at the base of the bill and throat. The wings are long and enable a buoyant style of flight. Grey-faced petrels are easily confused with the great-winged petrel (Pterodroma macroptera) where their ranges overlap in the Tasman Sea, as these species are morphologically very similar.
