The Mindanao hawk-owl or Mindanao boobook (Ninox spilocephala) is a species of owl in the family Strigidae that is endemic to the Philippines on the island of Mindanao. It was previously known as a subspecies of the Philippine hawk-owl, but was reclassified in 2012, as voice and other evidence suggested it a distinct species.[3] It is found in tropical moist lowland forest. It is threatened by habitat loss.

Description

EBird describes the bird as "A fairly small owl of lowland forest on Mindanao. Dark brown on the head and upperparts with speckles on the wing, a reddish-brown chest, a white belly with thick reddish-brown streaking, and yellowish eyes. Similar to chocolate boobook, but Mindanao is much smaller and lacks any white on the chest. Song is a short three-noted phrase “boo-woo! boo!” with the first and second notes slurred."[4]

The Mindanao hawk-owl is an earless species. The males and females look much alike.

Among the species complex, this owl is differentiated by its call which sounds closer to a dove than the typical screeching of the hawk owls. It also has smaller size and mottled dark and light rufous brown streaking on its breast and whitish belly. [5]

It, along with the even smaller Luzon hawk-owl, are among the smallest in the Philippine hawk-owl species complex, at 18cm. This is smaller than the Mindoro hawk-owl and Sulu hawk-owl which are 20cm tall. These species are dwarfed by the much larger Camiguin hawk-owl, Romblon hawk-owl and Cebu hawk-owls at 25cm tall.[5]

Habitat and Conservation Status

Its habitat is in tropical moist lowland primary forest. [5]

The IUCN Red List classifies this bird as near-threatened with population believed to be declining. This species' main threat is habitat loss with wholesale clearance of forest habitats as a result of legal and illegal logging, mining, conversion into farmlands and plantations and urbanization. Its entire range has suffered extensive lowland deforestation. In 1988, forest cover had been reduced to an estimated 29% on Mindanao, most of it above 1,000 m

There are no species specific conservation programs going on at the moment but conservation actions proposed include more species surveys to better understand habitat and population. initiate education and awareness campaigns to raise the species's profile and instill pride in locals. Lobby for protection of remaining forest.[6]
