This species qualifies as Endangered as it probably breeds at fewer than five locations (although currently only known from one) and its population is suspected to be declining as a consequence of predation by rats.

Pterodroma arminjoniana (Sibley and Monroe 1990, 1993) has been split into P. arminjoniana, P. heraldica and P. atrata following Brooke (2004).
36 cm. Medium-sized, slight, dark grey-brown, gadfly petrel. Fairly uniform grey-brown plumage, somewhat paler on underparts. Greyer feather tips on forehead and chin give mottled appearance around bill. Underwing shows pale leading edge between carpal joint and body, and some silvery-white at base of primaries. Black bill. Pink legs, with pink feet proximally, black distally. Similar spp. Dark phase Kermadec Petrel P. neglecta slightly bigger, with white primary shafts, and wholly black legs.
