Principe scops owl
species of scops owl

The Principe scops owl (Otus bikegila) is a species of scops owl found only on Príncipe Island of São Tomé and Príncipe, an island country in the Gulf of Guinea off the coast of Africa. First noticed by its distinctive nighttime call, it was formally described in 2022. The first records of suspicions of its existence are from 1928. Given its low population numbers and tiny range, researchers have asked the IUCN to declare it Critically Endangered, and this status was granted in 2023. Its distribution is limited to native forests where human activity is low—in fact, its range is entirely within a protected area, the Príncipe Obô Natural Park—and it seems to prefer larger trees. It feeds on insects. Its predators include the Mona monkey and the black rat.
Call
The bird's call has been described as "tuu," repeated quickly, sometimes in duets. The birds begin to call almost as soon as it gets dark. Another of its calls is "cat-like" and can exist either in isolation or repetition.

Why this record matters
The phrase “species of scops owl” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 9, 2026. The linked authority identifier is Q28499458. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2022, 1928 and 2023.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
