Long-legged Bunting (Emberiza alcoveri)
This species was described based on subfossil remains that had been found on the island of Tenerife, Canary Islands.
The Long-legged Bunting had very long legs and short wings, which indicate that the species may even have been flightless, if so it would have been one of only a very, very few passerines that lost their flight abilities.
The species disappeared shortly after the Canary Islands were settled by the Guanches at around 1000 BCE.
