] is the largest living bird.]]

The largest living bird, a member of the ], is the ] (''Struthio camelus'') reaching a height of over 2.7&nbsp;m (9&nbsp;ft) and weighing over 156&nbsp;kg (345&nbsp;lb).<ref name="birding"> records</ref> Eggs laid by the Ostrich can weigh 1.4&nbsp;kg (3&nbsp;lb) and are the largest eggs (and thus single cells) in the world today.

The largest bird in the fossil record may be the extinct ]s of Madagascar, which were related to the ]. They exceeded 3&nbsp;m (10&nbsp;ft) and 500&nbsp;kg (1,120&nbsp;lb). The last of the elephant birds became extinct about 300 years ago. Of almost exactly the same proportions as the largest elephant birds was '']'' of Australia, part of a 26,000-year old group called ]s of the family ]. The tallest bird ever however was the ] (''Dinornis maximus''), part of the moa family of New Zealand that went extinct about 200 years ago. This moa stood up to 3.7&nbsp;m (12&nbsp;ft) tall<ref name=birding/> when it was erected in an unnatural position, but weighed about half as much as a large elephant bird or mihirung due to its comparatively slender frame.
The largest carnivorous bird was '']'', an extinct flightless bird from South America which reached a weight of 350 to 400&nbsp;kg (770 to 880&nbsp;lb) and a height of about 2.8&nbsp;m (9&nbsp;ft&nbsp;2&nbsp;in).

The largest bird ever capable of flight was '']'', a now extinct member of the ] group, with a wingspan of up to 8.3&nbsp;m (28&nbsp;ft), a length of over 3&nbsp;m (10&nbsp;ft) and a body weight of 80&nbsp;kg (175&nbsp;lb).

*'''Waterfowl''' ('']'')
:The largest species in general is the ] (''Cygnus buccinator''), which can reach an overall length of 1.82&nbsp;m (6&nbsp;ft), a wingspan of 3&nbsp;m (10&nbsp;ft) and a weight of 17.3&nbsp;kg (38&nbsp;lb). However, the heaviest waterfowl ever recorded was an ] ] (''Cygnus olor'') from Poland, who weighed nearly 23&nbsp;kg (50&nbsp;lb). The members of the previously mentioned ] are now classified as members of this order, making them the largest "]" that ever lived.
*'''Swifts & allies''' ('']'')
:The ] (''Streptoprocne semicollaris'') and the ] (''Hirundapus celebensis'') reach similar large sizes, at up to 225&nbsp;g (8&nbsp;oz) and 25&nbsp;cm (10&nbsp;in). The ]s are also traditionally included in this order, the largest species of which is easily the ] (''Patagona gigas'').
*'''Nightjars & allies''' ('']'')
:The largest species of this order is the ] (''Nycitbius grandis''), the maximum size of which is about 680&nbsp;g (1.5&nbsp;lb) and 60&nbsp;cm (2&nbsp;ft).
*'''Shorebirds''' ('']'')
:The largest species in this diverse order is the ] (''Larus marinus''), attaining a size of as much as 85&nbsp;cm (34&nbsp;in) and 2.5&nbsp;kg (5½&nbsp;lb). The extinct ] (''Pinguinus impennis''), at 5&nbsp;kg (11&nbsp;lb) was the record holder, however.
*'''Herons & allies''' ('']'')
:The largest species, if measured in regard to body weight and wingspan, is the ] (''Vultur gryphus''), reaching a wingspan of 3.2&nbsp;m (10.7&nbsp;ft)<ref name=birding/> and a weight of 15&nbsp;kg (33&nbsp;lb). The longest-bodied species is probably the ] (''Ephippiorhynchus senegalensis''), which often exceeds 1.5&nbsp;m (5&nbsp;ft) tall. Most of the largest flying birds in the fossil record, including the largest, '']'', were members of the Ciconiiformes.
*'''Mousebirds''' ('']'')
:The mousebirds are remarkably uniform, but the largest species is seemingly the ] (''Colius striatus''), at 2&nbsp;oz (60&nbsp;g) and over 14&nbsp;in (35&nbsp;cm).
*'''Pigeons''' ('']'')
:The largest species of the pigeon/dove complex is the ] (''Goura victoria''). Some exceptionally large ones have reached 3.7&nbsp;kg (8.2&nbsp;lb) and 85&nbsp;cm (34&nbsp;in).

*'''Kingfishers & allies''' ('']'')
:The largest species is the ] (''Bucorvus leadbeateri''), reaching sizes of as much as 6&nbsp;kg (13.5&nbsp;lb) and nearly 1.2&nbsp;m (4&nbsp;ft) in length.

Slightly larger, at up to 1.4&nbsp;m (4.7&nbsp;ft) long, wingspan 3&nbsp;m (10&nbsp;ft) and weighing at least 15&nbsp;kg (33&nbsp;lb), was the now extinct ] (''Harpagornis moorei''), the largest ] known.
*'''Gamebirds''' ('']'')
