Chocolate Boobook Ninox randi


Justification of Red List Category
This newly-split owl is suspected to be undergoing moderately rapid population declines owing to the conversion and fragmentation of its Philippine lowland forest habitat. It has therefore been listed as Near Threatened.

Population justification
The global population size has not been quantified, but the species is reported to be common to uncommon (del Hoyo et al. 1999).

Trend justification
Based on on-going forest loss and degradation within the range of the species it is suspected to be in moderately rapid population decline (approaching 30% over three generations [c.12 years]).

Distribution and population

Ninox randi is endemic to the Philippines, where it is found on the islands of Basilan, Cebu, Luzon, Marinduque, Mindanao, Mindoro, Negros and Siquijor.


N. randi inhabits forested and wooded habitats, including some modified areas (del Hoyo et al. 1999, König and Weick 2008).


Deforestation in the Philippines is reported to have been very rapid in recent decades, and it is estimated that the country lost c.40% of its forest cover in the 20 years between 1970 and 1990 (Uitamo 1999). Data from ESSC (Environmental Science for Social Change) suggest that the area of closed-canopy forest in the Philippines decreased by c.44% between 1987 and 2002 (Walpole 2010). Encroachment affects protected areas, such as Bataan Natural Park, Luzon, where old growth forest is estimated to have declined by 65% between 1987-1993 and 2002 (per A. Jensen in litt. 2013). Forest is being lost principally for timber extraction and agricultural expansion (Suarez and Sajise 2010, Lasco et al. 2011), with other drivers being mining and development.

Conservation actions

Conservation Actions Underway
This species presumably occurs in a number of protected areas.

Conservation Actions Proposed
Carry out surveys to assess the total population size. Use remote sensing methods to monitor habitat trends. Increase the area of suitable habitat that receives effective protection. Carry out habitat restoration.
