Prehistoric birds are various taxa of birds that became extinct before recorded history, or more precisely, before they could be studied alive by bird scientists. They are known from subfossil remains and sometimes folk memory, as in the case of Haast's Eagle from New Zealand.Birds (Aves) are generally believed to have evolved from feathered dinosaurs, and there is no real dividing line between birds and dinosaurs except of course that the former survived the Cretaceous-Tertiary extinction event and the latter did not. For the purposes of this article, a "bird" is considered to be any member of the clade Neornithes, that is the bird lineage as exists today. The other lineages of the Aves also became extinct at the end of the Cretaceous. Taxon extinctions taking place before the Late Quaternary happened in the absence of significant human interference. Rather, reasons for extinction are stochastic abiotic events such as bolide impacts, climate changes, mass volcanic eruptions etc.
