Title: Wildlife of Antarctica
Content: These two similar types of gigantism are believed to be related the cold water, which can contain high levels of oxygen, combined with the low metabolic rates ("slow life") of animals living in such cold environments. The rocky shores of mainland Antarctica and its offshore islands provide nesting space for over 100 million birds every spring. These nesters include species of albatrosses, petrels, skuas, gulls and terns. The insectivorous South Georgia pipit is endemic to South Georgia and some smaller surrounding islands. Ducks, the South Georgia pintail and Eaton's pintail, inhabit South Georgia, Kerguelen and Crozet. The flightless penguins are

Title: Flightless cormorant
Content: the 1983 an El Niño-Southern Oscillation (ENSO) event resulted in a 50% reduction of the population to just 400 individuals. The population recovered quickly, however, and was estimated to number 900 individuals by 1999. This species inhabits the rocky shores of the volcanic islands on which it occurs. It forages in shallow coastal waters, including bays and straits. Flightless cormorants are extremely sedentary, remaining most or all of their lives, and breeding, on local stretches of coast-line several hundred metres long. Their sedentary nature is reflected in a genetic differentiation between the main colonies, and particularly between Fernandina and Isabela

Title: Rookery
Content: existence of rookery-like colonies in the pterosaur "Pterodaustro". <br> Rookery A rookery is a colony of breeding animals, generally birds. Rooks – northern-European and central-Asian members of the crow family – nest in prominent colonies (multiple nests) at the tops of trees. The word applies to the nesting place of birds, such as crows and rooks, the source of the term. The breeding grounds of colony-forming seabirds and marine mammals (true seals or sea lions) and even some turtles are also referred to as rookeries. The term "rookery" was also borrowed as a name for dense slum housing in nineteenth-century

Title: Southern Ocean
Content: – fairly uniform temperatures of the deep ocean at the poles and the equator which differ by no more than 5 °C, and the major current systems or marine conveyor belt which transport egg and larva stages. The rocky shores of mainland Antarctica and its offshore islands provide nesting space for over 100 million birds every spring. These nesters include species of albatrosses, petrels, skuas, gulls and terns. The insectivorous South Georgia pipit is endemic to South Georgia and some smaller surrounding islands. Freshwater ducks inhabit South Georgia and the Kerguelen Islands. The flightless penguins are all located in the

Title: Southern Indian Ocean Islands tundra
Content: historically a source of vitamin C for sailors, is found on all the islands, not only the Kerguelens. There are also a number of endemic lichens and liverworts. The islands are home to birds and insects such as butterflies, moths, weevils, and spiders as well as wildlife typical of the southern oceans such as penguins, seals and seabirds. This ecoregion is a melting pot where related Antarctic and subantarctic species and subspecies co-exist, for example the following can all be found here: the sooty albatrosses ("Phoebetria fusca"), light-mantled albatross ("Phoebetria palpebrata)", northern giant petrel ("Macronectes halli"), southern giant petrel ("Macronectes

Question: Which flightless marine birds of the southern hemisphere live in rookeries?
Answer: Penguins
