80–95 cm, wingspan 150–200 cm. Resembles Southern Giant Petrel but bill tip is reddish-brown; lacks white morph. Breeds subantarctic islands (South Georgia, Macquarie, Auckland). Ranges north into subtropics; scavenges offal and carrion at sea. Near Threatened due to longline bycatch.
Antarctic Prion
25–28 cm, wingspan 58–66 cm. Classic prion pattern: pale blue-grey, white below, bold dark M across upperwing. Medium-broad bill. Most abundant and widespread prion; breeds South Georgia, Heard, Kerguelen, Macquarie. Feeds on crustaceans; makes deep dives compared to congeners.
