Source-derived summary

The Philippine eagle-owl (Ketupa philippensis) is a vulnerable species of owl belonging to the family Strigidae. It is endemic to the Philippines, where it is found in lowland forests on the islands of Catanduanes, Samar, Bohol, Mindanao, Luzon, Leyte and possibly Sibuyan. While it is the largest owl in the Philippines, it is relatively small compared to other members of its genus. It is a vulnerable species with its population on the decline. Its main threats are habitat destruction, hunting and poaching for the pet trade.

Description

The Philippine eagle-owl has a total wingspan of about 48 inches, and with a total length of 40–50 cm (15.5–19.5 in) and a wing-length of about 35 cm (14 in), (where typically a female would size larger than a male) it is the largest owl in the Philippines, but among the smallest members of the genus Ketupa. It is overall rufous with a lighter belly and yellow eyes. It has a warm brown coloring with many markings on its back, with a bird call pitch of a long whistle that rises shortly and falls at the end. It is also described as being incredibly bulky and having tufted ears, closely resembling the buffy fish-owl (Ketupa ketupu). The subspecies K. p.

Editorial summary

Begin with the source’s own compact description: “Philippine eagle-owl” is species of bird. The dossier treats that line as a proposition to test through Philippine, eagle-owl and species, not as a finished interpretation.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 207-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Philippine, eagle-owl and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of bird” 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.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q980495. None of the 0 selected statements returned an explicit reference.

Critical limits

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.

How to read it
