Number of birds in country reported threatened by IUCN.

Species assessed by the International Union for the Conservation of Nature (IUCN) and documented in the IUCN Red List of Threatened Species TM (RLTS) have been used to calculate country summary statistics on the number of endemic and threatened species (IUCN, 2020).

Species included in the Red List are classified into the following categories based on Red List criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation:

Threatened species fall into one of the following three categories:

1) Critically Endangered (CR) – Extremely high risk of extinction in the wild.

2) Endangered (EN) – High risk of extinction in the wild. 3) Vulnerable (VU) – High risk of endangerment in the wild.


Country lists of (protected) Threatened (Critically Endangered, Endangered, Vulnerable) and Near Threatened species are derived by the previously described overlay within protected areas and species ranges,aggregating the results by the ISO3 code reported for the Protected Area by WCMC.
