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 ...

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). [22]
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]
The deployment of capillary depth recorders, which record the maximum dive depth undertaken by a bird, has shown that while some species, such as the wandering albatross, do not dive deeper than a metre, some species, such as the light-mantled albatross, have a mean diving depth of almost 5 m (16 ft) and can dive as deep as 12.5 m (41 ft). [34]
[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.
The female is a brown bird with black-barred buffy underparts. Their feet are strong, large-clawed and pink in color. The display dance of the twelve-wired bird of paradise is called a wire-wipe display and it is performed by males to attract females by showing their flank plumes and bare pigmented thighs. Males use their 12 flank plume "wires ...
Larks, or the family Alaudidae, are small- to medium-sized birds, 12 to 24 cm (4.7 to 9.4 in) in length and 15 to 75 g (0.5 to 2.6 oz) in mass. [14] The smallest larks are likely the Spizocorys species, which can weigh only around 14 g (0.49 oz) in species like the pink-billed lark and the Obbia lark , while the largest lark is the Tibetan lark .
