Since A. magnificens is known to have lived in terrestrial environments, another good point of comparison is the Andean condor, the largest extant flighted land bird both in average wingspan and weight, with the former spanning up to 3.3 m (10 ft 10 in) with an average of around 2.82 m (9 ft 3 in), and the latter reaching a maximum of up to 15 ...
The largest bird in the fossil record may be the extinct elephant birds (Vorombe/Aepyornis) of Madagascar, which were related to the ostrich. They exceeded 3 m (9.8 ft) in height and 500 kg (1,100 lb) in weight. [44] The last of the elephant birds became extinct approximately 1000 years ago.
The marabou stork is a massive bird: large specimens are thought to reach a height of 152 centimetres (5 feet) and a weight of 9 kg (20 lb). [8] [9] A wingspan of 3.7 m (12 ft) was accepted by Fisher and Peterson, who ranked the species as having the largest wing-spread of any living bird. Even higher measurements of up to 4.06 m (13.3 ft) have ...
The structure of the fossils also suggest that these birds may have been swifter than originally thought. [25] A skull from a smaller subspecies of this bird was also found recently. With this fossil, it was found that the internal structure of the beak is hollow and reinforced with thin-walled trabeculae.
Late Quaternary prehistoric birds are avian taxa that became extinct during the Late Quaternary – the Late Pleistocene or Early Holocene – and before recorded history, specifically before they could be studied alive by ornithological science. They had died out before the period of global scientific exploration that started in the late 15th ...

Like the ostrich, rhea, cassowary, emu, kiwi and extinct moa, elephant birds were ratites; they could not fly, and their breast bones had no keel. Because Madagascar and Africa separated before the ratite lineage arose, [6] elephant birds has been thought to have dispersed and become flightless and gigantic in situ. [7]
Teratornithidae is an extinct family of very large birds of prey that lived in North and South America from the Late Oligocene to Late Pleistocene. They include some of the largest known flying birds. Its members are known as teratorns.
