June 27, 2013 — On São Miguel Island in the Azores, there used to exist a small, nocturnal bird of prey, related to the European scops owl, named Otus frutuosoi, which was very probably driven to extinction with the arrival of the first settlers in the 15th century. An international study, in which Spanish researchers participated, has for the first time identified fossils of this species endemic to the island.
On 28 August 2011 researchers Juan Carlos Rando, from the University of La Laguna (Tenerife), and Josep Antoni Alcover from the Mediterranean Institute for Advanced Studies in Mallorca unearthed some small fossil bones buried not far below the ground of the Água de Pau cave (São Miguel Island, Azores, Portugal).
Two years later, an article published by the journal Zootaxa has revealed that the remains found belong to an extinct species of scops owl which has been given the name Otus frutuosoi in honour of the 16th-century Azorean historian Gaspar Frutuoso.
Carbon dating the fossils indicates that they are from 1,970 years ago. The hypothesis entertained by the researchers is that the arrival of human beings to the archipelago in the 15th century changed its ecosystem and caused the extinction of the species.
