Argentavis was among the largest flying birds to ever exist, holding the record for heaviest flying bird, although it was surpassed in wingspan after the 2014 description of Pelagornis sandersi, which is estimated to have possessed wings some 20% longer than those of Argentavis. [1] [2]

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 ...

It was a flightless or nearly flightless bird and it is believed to be the largest owl that ever existed. It lived on the island of Cuba. The first fossil specimen was mistakenly described as a bird in the family Phorusrhacidae, in part because the bones were so large.
Estimates of the body mass of Aepyornis maximus span from around 275 kilograms (606 lb) [20] to 700–1,000 kilograms (1,500–2,200 lb) [16] making it one of the largest birds ever, alongside Dromornis stirtoni and Pachystruthio dmanisensis. [21] [22] Females of A. maximus are suggested to have been larger than the males, as is observed in ...
