Sao Miguel Rail (Rallus carvaoensis)

The Sao Miguel Rail was described in 2015 based on subfossil remains that had been excavated from deposits from the Gruta do Carvão on the island of São Miguel, one of the Azores Islands, Portugal.

Like its congeners from the other islands of the Azores, also known by subfossil remains, this one too was a derivative of the Water Rail (Rallus aquaticus L.) from the European mainland. [1]
