The heaviest extant flying birds are known to weigh up to a maximum of 21 kg (46 lb) (there are several contenders, among which are the European great bustard and the African kori bustard). An individual mute swan, which may have lost the power of flight due to extreme weight, was found to have weighed 23 kg (51 lb). [17]
The common ostrich is the largest living bird Aepyornis maximus, one of the largest birds ever. The largest extant species of bird measured by mass is the common ostrich (Struthio camelus), closely followed by the Somali ostrich (Struthio molybdophanes). A male ostrich can reach a height of 2.8 metres (9.2 feet) and weigh over 156.8 kg (346 lb ...
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 5.5 m (18 ft), a length of up to 1.25 m (4.1 ft), a height on the ground of up to 1.75 m (5.7 ft) and a body weight of at least 71 kg (157 lb).
There are almost 10,000 species of birds on Earth and they come in all different shapes and sizes — from the tiny bee hummingbird to the massive ostrich. At only around one fifth of the size of ...
A partial skeleton of this enormous teratorn was found from La Pampa, Argentina. It is one of the largest flying birds known to have existed, only likely exceeded by measurement of wingspan by Pelagornis sandersi, discovered in 1983. [6]
The species of Aepyornis are amongst the largest birds, with weights of 235 kilograms (520 lb) estimated for A. hildebrandti [2] and 275–1,000 kilograms (610–2,200 lb) for A. maximus, making it one of the largest, if not the largest bird to have ever lived, [10] [2] with the latter reaching 3 metres (9.8 ft) in height.
The Andean condor is the largest living land bird capable of flight if measured in terms of average weight and wingspan, although male bustards of the largest species (far more sexually dimorphic in size) can weigh more. [14] [19] [20] The mean wingspan is around 283 cm (9 ft 3 in) and the wings have the largest surface area of any extant bird ...
The trumpeter swan is the largest extant species of waterfowl, and both the heaviest and longest native bird of North America. Adults usually measure 138–165 cm (4 ft 6 in – 5 ft 5 in) long, though large males can exceed 180 cm (5 ft 11 in) in total length. [3] [14] [15] [16] The weight of adult birds is typically 7–13.6 kg (15–30 lb ...
