Late Quaternary Prehistoric Birds - Late Quaternary Avian Extinctions

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 Wikipedia conservation status category "Prehistoric" in their individual accounts.
