Today in vc i was with someone but he just kept saying he is the biggest bird, what does this mean?
The largest bird in the fossil record may be the extinct elephant bird (Vorombe) of Madagascar, whose closest living relative is the kiwi. Elephant birds exceeded 3 m (9.8 ft) in height, weighed over 500 kg (1,100 lb)[4] and are estimated to have become extinct approximately 1,000 years ago. The Dromornis stirtoni of Australia, part of a 26,000-year-old group called mihirungs of the family Dromornithidae,[5] were of similar proportions to the largest elephant birds.
The largest carnivorous bird was Brontornis, an extinct flightless bird from South America which reached a weight of 350 to 400 kg (770 to 880 lb) and a height of approximately 2.8 m (9 ft 2 in).[6]
The tallest recorded bird was the South Island giant moa (Dinornis robustus), part of the moa family of New Zealand that went extinct around 1500 CE. This particular species of moa stood at 3.7 m (12 ft) tall[1] but only weighed about half as much as a large elephant bird or mihirung due to its comparatively slender frame.[4]
The heaviest bird ever capable of flight was Argentavis magnificens, the largest member of the extinct family Teratornithidae. The Argentavis was found in Miocene-aged fossil beds of Argentina and had a wingspan up to 5–6 m (16–20 ft), a length of up to 1.26 m (4.1 ft), a height of up to 1.5–2 m (4.9–6.6 ft) and a body weight of at least 71 kg (157 lb).[4][7] Pelagornis sandersi is another contender for the largest-known flying bird ever, rivaling Argentavis with a wingspan of up to 7.3 m (24 ft).[8]
