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 ...
[12] [13] For comparison, the living bird with the largest wingspan is the wandering albatross, averaging 3 m (9 ft 10 in) and spanning up to 3.7 m (12 ft 2 in). When grounded, Argentavis' height has been estimated at 1.5 to 1.8 m (4 ft 11 in to 5 ft 11 in), roughly equivalent to that of an adult human. Furthermore, its total length (from bill ...

The largest species of Procellariiformes is the wandering albatross (Diomedea exulans) of the sub-Antarctic oceans, which has the largest wingspan of any living bird. The maximum dimensions of this species are a length of 1.44 m (4.7 ft) and a wingspan of 3.65 m (12.0 ft). [49] Unverified specimens have been reported to measure 5.3 m (17 ft). [44]
A 1983 study gives a range of wingspan of 2.938–3.379 m (9.64–11.09 ft) and a weight of 13.7 kg (30 lb). [ 8 ] The finger bones of the Teratornis were fused as in all modern birds; however, part of the index finger forms a shelf which aided in bearing the load of long and stout primaries , enabling the bird to utilize strong upcurrents in ...
Procellariiforms range in size from the very large wandering albatross, at 11 kg (24 lb) and a 3.6-metre (12-foot) wingspan, to tiny birds like the least storm petrel, at 20 g (0.71 oz) with a 32-centimetre (13-inch) wingspan, [27] and the smallest of the prions, the fairy prion, with a wingspan of 23 to 28 cm (9.1 to 11.0 in).

The American kestrel is sexually dimorphic, although there is some overlap in plumage coloration between the sexes. The bird ranges from 22 to 31 cm (8.7 to 12.2 in) in length [12] with a wingspan of 51–61 cm (20–24 in). The female kestrel is larger than the male, though less so than larger falcons, being typically about 10% to 15% larger ...
It stood about 75 centimetres (30 in) tall with an estimated wingspan of perhaps 3.5 to 3.8 metres (11 to 12 ft), and weighed about 15 kilograms (33 lb); making it about a third bigger than extant condors. It became extinct at the end of Pleistocene, some 10,000 years ago. Teratornis woodburnensis. [3]
