As of December 2019, the International Union for Conservation of Nature (IUCN) listed 223 critically endangered avian species, including 19 which are tagged as possibly extinct or possibly extinct in the wild. [1] [2] 2% of all evaluated avian species are listed as critically endangered. No subpopulations of birds have been evaluated by the IUCN.
Additionally 55 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. [3] 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". [4]

Bird Paradise is an aviary located in Mandai, Singapore. Opened on 8 May 2023, it replaced the Jurong Bird Park and forms a part of the Mandai Wildlife Reserve, consisting of the Singapore Zoo, Night Safari, River Wonders and the upcoming Rainforest Wild Park. Bird Paradise covers approximately 17 hectares, with larger and double the walk-in aviaries than the previous Jurong Bird Park. The aviary was designed by Singaporean architectural firm, RSP Architects Planners & Engineers.
