It contains all or parts of five continents (Antarctica, Australia, about 90% of South America, the southern third of Africa, and several southern islands off the continental mainland of Asia), four oceans (Indian, South Atlantic, Southern, and South Pacific) and most of the Pacific Islands in Oceania. Its surface is 80.9% water, compared with 60.7% water in the case of the Northern Hemisphere, and it contains 32.7% of Earth's land.Owing to the tilt of Earth's rotation relative to the Sun and the ecliptic plane, summer is from December to March and winter is from June to September. September 22 or 23 is the vernal equinox and March 20 or 21 is the autumnal equinox. The South Pole is in the center of the southern hemispherical region.  less

Some definitions apply the term especially to birds in freshwater habitats, though others make no distinction from birds that inhabit marine environments. In addition, some water birds are more terrestrial or aquatic than others, and their adaptations will vary depending on their environment. These adaptations include webbed feet, bills and legs adapted to feed in water, and the ability to dive from the surface or the air to catch prey in water.
  
  The term aquatic bird is sometimes also used in this context. A related term that has a narrower meaning is waterfowl. Some birds of prey, such as ospreys and sea eagles, take prey from water but are not considered water birds. The term waterbird is also used in the context of conservation to refer to any birds that inhabit or depend on bodies of water or wetland areas. Examples of this use include the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) and the Wallnau Waterbird Reserve.
  Some examples of water birds are:
  
  Seabirds (marine birds, such as penguins and gulls)
  Shorebirds (waders, order Charadriiformes)
  Anseriformes (ducks, geese, swans, magpie geese, screamers)
  Grebes (order Podicipediformes)
  Loons (order Gaviiformes)
  Ciconiiformes (storks, herons, egrets, ibises, spoonbills and others)
  Pelecaniformes (pelicans and others)
  Flamingos (order Phoenicopteriformes)
  Some members of the order Gruiformes (including cranes and rails, crakes, coots and moorhens)
  Kingfishers (mainly the water kingfishers, sometimes the river kingfishers, and rarely the tree kingfishers)
  One family of passerines, the dippers...    less

There are over 60 extant species including the well known ratites (ostrich, emu, cassowary, rhea and kiwi) and penguins. The smallest flightless bird is the Inaccessible Island rail (length 12.5 cm, weight 34.7 g). The largest (both heaviest and tallest) flightless bird, which is also the largest living bird, is the ostrich (2.7 m, 156 kg). Ostriches are farmed for their decorative feathers, meat and their skins, which are used to make leather.
  Many domesticated birds, such as the domestic chicken and domestic duck, have lost the ability to fly for extended periods, although their ancestral species, the red junglefowl and mallard, respectively, are capable of extended flight. A few particularly bred birds, such as the Broad Breasted White turkey, have become totally flightless as a result of selective breeding; the birds were bred to grow massive breast meat that weighs too much for the bird's wings to support in flight.
  Flightlessness has evolved in many different birds independently. There were also other families of flightless birds, such as the now extinct Phorusrhacidae, that evolved to be powerful terrestrial predators. Taking this to a greater extreme, the terror birds (and their relatives the bathornithids), eogruids, geranoidids, gastornithiforms, and dromornithids (all extinct) all evolved similar body shapes – long legs, long necks and big heads – but none of them were closely related. Furthermore, they also share traits of being giant, flightless birds with vestigial wings, long legs, and long necks with some of the ratites, although they are not related.  less
