|Scientific Name:||Otus gurneyi|
|Species Authority:||(Tweeddale, 1879)|
Mimizuku gurneyi (Tweeddale, 1879)
|Taxonomic Notes:||Mimizuku gurneyi has been transferred to the genus Otus on the basis of the evidence presented in Miranda et al. (2011).|
|Red List Category & Criteria:||Vulnerable A2c+3c+4c;C2a(i) ver 3.1|
|Facilitator/Compiler(s):||Benstead, P., Bird, J., Davidson, P., Derhé, M., Lowen, J., Peet, N.|
This owl has a small population which is undergoing a rapid decline and severe fragmentation as a result of extensive deforestation. It therefore qualifies as Vulnerable.
|Range Description:||Otus gurneyi is endemic to the Philippines, where it is known from Dinagat, Siargao and Mindanao. It has a relatively widespread distribution on Mindanao, where it has been discovered at eight new sites since 1990. However, its status is uncertain and, although it is likely to be under-recorded, it is considered to be probably uncommon at best.|

|Population:||The population size is preliminarily estimated to fall into the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.|
|Habitat and Ecology:||It inhabits primary, secondary and selectively logged dipterocarp forests, primarily in the lowlands up to 670 m, with occasional records up to 1,300 m, including in mossy forest.|
|Major Threat(s):||Its entire range has suffered extensive lowland deforestation. In 1988, forest cover had been reduced to an estimated 29% on Mindanao and in 1992 no more than 724 km2 of closed-canopy forest remained on Samar. These figures are likely to be overestimates, with most remaining lowland forest tracts leased to logging concessions and mining applications. Dinagat has been almost entirely deforested as a result of illegal logging and chromite surface-mining.|
Conservation Actions Underway
CITES Appendix I and II. It occurs in several protected areas, including Mt Apo and Mt Kitanglad Natural Parks and Siargao Island. There are older records from Mt Hilong-hilong Watershed Reserve and Mt Matutum Forest Reserve, which has been proposed as a national park. In the 1990s, it featured on a bilingual environmental awareness poster in the "Only in the Philippines" series. Conservation Actions Proposed
Conduct nocturnal surveys, using voice playback, to establish presence/absence in poorly surveyed areas of Mindanao (e.g. Mts Three Kings, Diwata and Dapiak) and Samar. Conduct more intensive fieldwork to assess abundance, elevational range and habitat requirements at key sites. Promote improved protection of remaining forest at the sites listed above and campaign for a protected area in south Mindanao to encompass the cluster of sites with recent records.
