Northern Giant Petrel

Macronectes halli

The northern giant petrel (Macronectes halli), also known as Hall's giant petrel, is a large predatory seabird of the southern oceans. Its distribution overlaps broadly, but is slightly north of, the similar southern giant petrel (Macronectes giganteus). Its plumage consists of grey-brown body with lighter coloured forehead, sides of face, and chin. Its bill is between 90 and 110 mm (3.5–4.3 in) long, slightly longer on average than the southern giant petrel, and is pinkish yellow with a brown tip. Its eyes are grey. The tarsus of the northern giant petrel is slightly longer on average than the southern species, but the southern has longer wings on average. The juvenile Macronectes halli is entirely dark brown and lightens as it ages. It can be differentiated from Macronectes giganteus by the top of the bill, which on the southern species is green.
