Monotypic species


Members of the genus Mimizuku are quite large owls. They were, for some time, regarded as part of the genus Otus , but major differences in size, appearance and habits, have caused it to be placed in a separate genus. In terms of its DNA, it is closer to Otus than it is to Bubo . There is but one species, resident in the southern part of the Philippines.

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.
Mimizuku gurneyi is endemic to the Philippines, where it is known from Samar (one record), 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.
