Today one species is on the brink of extinction and three other species range from Vulnerable to Critically Endangered, all impacted by invasive species. [1] Further parrot species were not introduced by acclimatisation societies, but occasional releases, both deliberate and accidental, have resulted in self-sustaining populations of some ...
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.

See: List of endangered birds, List of critically endangered birds. Vulnerable, endangered and critically endangered species are collectively referred to as threatened species by the IUCN. Additionally, 53 avian species (0.48% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full
Many birds follow strict time schedules in their activities. These are often dependent upon environmental cues. Birds also are sensitive to day length, and this awareness is especially important as a cue for migratory species. The ability to orient themselves during migrations is typically attributed to birds' superior sensory abilities, rather ...
