List of endangered birds

In December 2019, the International Union for Conservation of Nature (IUCN) listed 460 endangered avian species.^[1] Of all evaluated avian species, 4% are listed as endangered. No subpopulations of birds have been evaluated by the IUCN.

Extinct in the wild (EW): 5 species
Critically endangered (CR): 223 species
Endangered (EN): 460 species
Vulnerable (VU): 798 species
Near threatened (NT): 1,001 species
Least concern (LC): 8,460 species
Data deficient (DD): 46 species

Avian species (IUCN, 2020-3)

10,999 extant species have been evaluated
10,947 of those are fully assessed^{[lower-alpha 1]}
9,461 are not threatened at present^{[lower-alpha 2]}
1,481 to 1,533 are threatened^{[lower-alpha 3]}
164 to 183 are extinct or extinct in the wild:
- 159 extinct (EX) species^{[lower-alpha 4]}
- 5 extinct in the wild (EW)
- 19 possibly extinct [CR(PE)]

For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered birds are listed separately. There are 683 avian species which are endangered or critically endangered.

Additionally 53 avian species (0.48% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN.^[2] While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed".^[3]
