The new owl species was described in the open-access journal ZooKeys, based on multiple lines of evidence such as morphology, plumage color and pattern, vocalizations, and genetics. Data was gathered and processed by an international team led by Martim Melo (CIBIO and Natural History and Science Museum of the University of Porto), Bárbara Freitas (CIBIO and the Spanish National Museum of Natural Sciences) and Angelica Crottini (CIBIO).

The bird is now officially known as the Principe Scops-Owl, or Otus bikegila.

"Otus" is the generic name given to a group of small owls sharing a common history, commonly called scops-owls. They are found across Eurasia and Africa and include such widespread species as the Eurasian Scops-Owl (Otus scops) and the African Scops-Owl (Otus senegalensis).

The scientists behind the discovery further explain that the species epithet "bikegila" was chosen in homage of Ceciliano do Bom Jesus, nicknamed Bikegila—a former parrot harvester from Príncipe Island and now a ranger of its natural park.

"The discovery of the Principe Scops-Owl was only possible thanks to the local knowledge shared by Bikegila and by his unflinching efforts to solve this long-time mystery," the researchers say. "As such, the name is also meant as an acknowledgment to all locally-based field assistants who are crucial in advancing the knowledge on the biodiversity of the world."
