Camiguin boobook
Also known as: Camiguin hawk-owl · Ninox leventisi · Kugkug (local name)
Definition
The Camiguin boobook (Ninox leventisi), also called the Camiguin hawk-owl, is a small owl endemic to the island of Camiguin in the southern Philippines. Long treated as a subspecies of the Philippine hawk-owl, it was recognized as a distinct species in 2012 based on voice and other evidence, and is noted as the country’s only owl with greenish-yellow or grayish eyes.

Examples and Analogies
The Camiguin boobook is to Philippine owls what island finches were to Darwin: a single ancestral hawk-owl population scattered across islands evolved separate voices and plumages, and Camiguin’s version sings a duet all its own, distinguishable to researchers by ear before genetics confirmed the split.
Usage Scenarios
The species is a target of ornithological surveys and birding ecotours on Camiguin, where its calls are played back cautiously during night surveys; it also serves conservation planners as an indicator of forest condition on the small island and appears in species checklists used in environmental impact assessments.
Strategies
Conservation strategy centers on protecting Camiguin’s remaining forest patches in the island’s protected mountain area, limiting land conversion, and continued banding-free acoustic monitoring, since the owl’s restricted range makes habitat protection effectively equivalent to species protection.
Security and Safety Measures
Researchers follow ethical playback protocols, keeping call broadcasts brief and spaced to avoid habituation or exposing territorial pairs; ecotour guides keep night walks small and on trails to avoid disturbing roosts and nesting sites.
Historical Context
Camiguin’s owls were known to local people as the kugkug long before science caught up. Specimens collected in the twentieth century sat within the Philippine hawk-owl complex until a 2012 revision by Rasmussen and colleagues split the complex into multiple species, naming Ninox leventisi for conservationist Stephen Leventisi and highlighting the Philippines’ underestimated owl diversity.
Challenges and Controversies
Like other single-island endemics, the boobook is vulnerable to deforestation, typhoons, and stochastic events because its entire population lives on one small island; population size is poorly quantified, and debates persist over threat categorization and how much gene flow, if any, occurs with owls on nearby Mindanao.
