A new species of extinct scops owl (Aves: Strigiformes: Strigidae: Otus) from São Miguel island (Azores archipelago, north Atlantic ocean)
The extinct São Miguel Scops Owl Otus frutuosoi n. sp. is described from fossil bones found in Gruta de Água de Pau, a volcanic tube in São Miguel Island (Azores Archipelago, North Atlantic Ocean). It is the first extinct bird described from the Azores and, after the Madeiran Scops Owl (O. mauli Ran...
