(Probably) Extinct Subspecies of Birds
Extinction of subspecies is a subject very dependent on guesswork. 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 just as well still exist, but are listed here due to any combination of absence of recent records, a known threat such as habitat destruction, and an observed decline.

Famous quotes containing the words extinct and/or birds:
“One realises, with horror, that the race of men is almost extinct in Europe. Only Christ-like heroes and woman-worshipping Don Juans, and rabid equality-mongrels. The old, hardy, indomitable male is gone.”
—D.H. (David Herbert)
“In almost all climes the tortoise and the frog are among the precursors and heralds of this season, and birds fly with song and glancing plumage, and plants spring and bloom, and winds blow, to correct this slight oscillation of the poles and preserve the equilibrium of nature.”
—Henry David Thoreau (1817–1862)
