Late Quaternary prehistoric birds

Prehistoric birds are various taxa of birds that became extinct before recorded history, or more precisely, before they could be studied alive by ornithologists. 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–Paleogene 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. Alternatively, species may have gone extinct due to evolutionary displacement by successor or competitor taxa – it is notable for example that in the early Neogene, seabird biodiversity was much higher than today; this is probably due to competition by the radiation of marine mammals after that time. The relationships of these ancient birds are often hard to determine, as many are known only from very fragmentary remains and due to the complete fossilization precludes analysis of information from DNA, RNA or protein sequencing.

Late Quaternary avian extinctions

This page lists bird taxa that have become extinct before they could be researched by science, but nonetheless survived into (geologically) recent times. Their remains are not or not completely fossilized and therefore may yield organic material for molecular analyses to provide additional clues for resolving their taxonomic affiliations. As these species' extinction coincided with the expansion of Homo sapiens across the globe, in most cases, anthropogenic factors have played a crucial part in their extinction, be it through hunting, introduced predators or habitat alteration. It is notable that a large proportion of the species are from oceanic islands, especially in Polynesia. Bird taxa that evolved on oceanic islands are usually very vulnerable to hunting or predation by rats, cats, dogs or pigs – animals commonly introduced by humans – as they evolved in the absence of mammalian predators and therefore only have rudimentary predator avoidance behavior. Many, especially rails, have additionally become flightless for the same reason and thus presented even easier prey.

The taxa in this list became extinct during the Late Quaternary – the Holocene or Late Pleistocene – but before the period of global scientific exploration that started in the late 15th century. More precisely, their extinction was coincident with the expansion of Homo sapiens beyond Africa and Eurasia, i.e. this list basically deals with extinctions between 40000 BC and 1500 AD. They should be classified with the "Prehistoric" in their individual accounts.

Taxonomic list of Late Quaternary prehistoric birds

The diverse group that includes storks, herons and New World vultures.

Pelecaniformes

The group that includes modern pelicans and cormorants.
