[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.
Teratornithidae is an extinct family of very large birds of prey that lived in North and South America from the Late Oligocene to Late Pleistocene. They include some of the largest known flying birds. Its members are known as teratorns.
Quetzalcoatlus (/ k ɛ t s əl k oʊ ˈ æ t l ə s /) is a genus of azhdarchid pterosaur that lived during the Maastrichtian age of the Late Cretaceous in North America. The type specimen, recovered in 1971 from the Javelina Formation of Texas, United States, consists of several wing fragments and was described as Quetzalcoatlus northropi in 1975 by Douglas Lawson.
Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night.

Many of the largest flying birds in the fossil record may have been members of the Ciconiiformes. The heaviest flying bird ever, Argentavis magnificens, is part of a group, the teratorns, that is considered an ally of the New World vultures. [86] The largest ibis is the giant ibis (Thaumatibis gigantea). Adults can grow to 102–106 cm (40–42 ...
Late Quaternary prehistoric birds are avian taxa that became extinct during the Late Quaternary – the Late Pleistocene or Early Holocene – and before recorded history, specifically before they could be studied alive by ornithological science. They had died out before the period of global scientific exploration that started in the late 15th ...
Analyzing a leg bone from a fossil site in Colombia, scientists have identified a massive “terror bird” that lived about 12 million years ago.
The black kite can reach an altitude of around 37,000 feet especially during their migratory flight to and from West Africa in the second week of September and the last week of May annually.
