National and international conservation projects and research publications such as redlists usually focus on species as a whole. Reliable information on the status of threatened subspecies usually has to be assembled piecemeal from published observations, such as regional checklists. Therefore, the following listing contains a high proportion of taxa that may still exist, but are listed here due to any combination of absence of recent records, a known threat such as habitat destruction, or an observed decline.
