context_page_description: The largest extant bird species, a member of the Struthioniformes, is the ostrich, from the plains of Africa and Arabia. A large male ostrich can reach a height of 2.8 metres and weigh over 156 kilograms. A mass of 200 kg has been cited for the ostrich but no wild ostriches of this massive weight have been verified. Eggs laid by the ostrich can weigh 1.4 kg and are the largest eggs in the world today.
  The largest extant bird by wingspan is the wandering albatross of the sub-Antarctic oceans. The maximum dimensions in this species are a length of 1.44 m and a wingspan of 3.65 m.
context_section_description: The largest species is easily the emperor penguin (Aptenodytes forsteri) of the Antarctic, with a maximum height of 1.35 m (4.4 ft) and weight of 46 kg (101 lb). The next largest living species is the king penguin, which grows up to a maximum of 18 kg (40 lb) and 1 m (3.3 ft) tall. At one time, possibly competing with the mammalian pinnipeds, a number of giant penguins existed. The largest is believed to be Anthropornis nordenskjoeldi, having reached a height of 1.8 m (5.9 ft) and a weight of up to 108 kg (238 lb).
