Found only on the island of Luzon, Worcester's buttonquail was known solely through drawings based on dated museum specimens collected several decades ago.
Scientists had suspected the species—listed as "data deficient" on the International Union for Conservation of Nature's 2008 Red List—was extinct.
The buttonquail is a reclusive bird, and no one knows how many may remain hidden. Link -via Digg
