Southern Giant Petrel
Giant petrels are the largest of the petrel family, which make up the order of tubenose or procellariiform seabirds, along with albatrosses, shearwaters, storm petrels, and diving petrels. The crucial feature used to distinguish the northern giant petrel from the closely related southern giant petrel is the color of the bill tip: reddish-brown in the northern, and greenish in the southern. This characteristic is not always easy to spot at sea. Some southerns are all white, except for the odd dark feathers. This color phase does not occur in northerns, helping with identification. White phase southerns are more common at southerly breeding sites and are absent at the northerly ones.
