List of largest birds


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 and weigh over. A mass of has been cited for the ostrich but no wild ostriches of this massive weight have been verified. Eggs laid by the ostrich can weigh 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.

Largest birds ever

The largest bird in the fossil record may be the extinct elephant birds of Madagascar, whose closest living relative is the kiwi. They exceeded in height and. The last of the elephant birds became extinct about 300 years ago. Of almost exactly the same upper proportions as the largest elephant birds was Dromornis stirtoni of Australia, part of a 26,000-year-old group called mihirungs of the family Dromornithidae. The largest carnivorous bird was Brontornis, an extinct flightless bird from South America which reached a weight of and a height of about. The tallest bird ever however was the giant moa, part of the moa family of New Zealand that went extinct around 1500 AD. This particular species of moa stood up to tall, but weighed about half as much as a large elephant bird or mihirung due to its comparatively slender frame.
The heaviest bird ever capable of flight was Argentavis magnificens, the largest member of the now extinct family Teratornithidae, found in Miocene-aged fossil beds of Argentina, with a wingspan up to, a length of up to, a height on the ground of up to and a body weight of at least. Rivaling Argentavis in wingspan if not in bulk and mass, another contender for the largest known flying bird ever is Pelagornis sandersi, which had a wingspan of up to.

Table of heaviest extant bird species

The following is a list of the heaviest extant bird species based on maximum reported or reliable mass, but average weight is also given for comparison. These species are almost all flightless, which allows for these particular birds to have denser bones and heavier bodies. Flightless birds comprise less than 2% of all extant bird species.
