Ranges are based on the IOC World Bird List for that species unless otherwise noted. Population estimates are of the number of mature individuals and are taken from the IUCN Red List. This list follows the taxonomic treatment (designation and order of species) and nomenclature (scientific and common names) of version 13.2 of the IOC World Bird ...
This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
The International Union for Conservation of Nature (IUCN) lists 35 extinct species, 146 possibly extinct species, two extinct in the wild species, and one possibly extinct in the wild species of amphibians. [1] [2]
The toucans are, due to their unique appearance, among the most popular and well known birds in the world. [12] Across their native range they were hunted for food and also kept as pets, and their plumage and bills were used for decorations. In some places anyone that discovers a nest is deemed its owner and is entitled to sell the birds within.
The largest known birds whose nests are predated upon by the toco toucan are the hyacinth macaw and buff-necked ibis; the nestlings of the latter weigh 200–300 g (7.1–10.6 oz), compared to the toucan's body mass of around 540 g (19 oz), and are killed by breaking their necks with sideways movements of the toucan's beak.

As of 2022, the International Union for Conservation of Nature (IUCN) listed 40 animal species as extinct in the wild. [1] That is approximately 0.04% of all evaluated animal species. The IUCN also lists five animal subspecies as extinct in the wild. This is a complete list of wild animal species and subspecies listed as extinct by the IUCN.
Version 2014.2 of the IUCN Red List of Threatened Species identified 77 (40 animal, 37 plant) extinct in the wild species, subspecies and varieties, stocks and subpopulations. For IUCN lists of extinct in the wild species by kingdom, see: Animals (kingdom Animalia) — IUCN Red List extinct in the wild species (Animalia)
