Luzon Scops-owl
Also known as: Luzon highland scops owl · Long-horned scops owl (from its scientific name)
Definition
The Luzon scops-owl (Otus longicornis) is a small owl endemic to the mountains of Luzon, Philippines. It is the highland counterpart of the larger Philippine scops-owl of the lowlands, sharing its island but occupying higher elevations in montane forest, where it hunts insects and other small prey at night.

Examples and Analogies
The pair formed by the Luzon scops-owl and the Philippine scops-owl is a textbook case of highland-lowland replacement also seen in other Philippine birds, where related species divide a single island by elevation rather than by geography.
Usage Scenarios
The species is a target of nocturnal birdwatching walks on Luzon mountain routes, where its whistled song is played back sparingly to locate territorial birds, and it is referenced in studies of montane forest fragmentation.
Strategies
Surveyors detect the owl by listening at dusk along montane roads and trails and identifying its distinct song, often confirming identity by silhouette rather than by torchlight views in the canopy.
Security and Safety Measures
Owl playback must be used sparingly to avoid stressing territorial birds, and the species is protected under Philippine wildlife law from trapping and trade.
Historical Context
It was separated from other Philippine scops-owls as collection knowledge of Luzon’s mountains improved in the late nineteenth century, and recent splits of owls across the archipelago have underscored how much owl diversity the islands hold.
Challenges and Controversies
Its population is suspected to be slowly declining as montane forest is cleared at its lower margins, and its fate is tied to the conservation of Luzon’s remaining unbroken forest from the Sierra Madre to the Cordillera.
