The Philippine Eagle-owl (Bubo philippensis) is a largish owl, measuring around 40 cm. in length. It has bright yellow eyes and a rufous-buff fascial disk. It is endemic to the Philippines where it inhabits lowland forests, generally below 650 m., on Luzon, Catanduanes, Samar, Leyte, Bohol, Mindanao and possibly Sibuyan. Its population is small, severely fragmented and declining as a result of lowland deforestation throughout its range. It is therefore classified as Vulnerable.

The Giant Scops-owl (Mimizuku gurneyi) is a medium-sized owl, measuring around 30 cm. in length, with dark eyes and conspicuous white eyebrows. It is endemic to the Philippines, where it is known from forests, primarily in the lowlands up to 650 m., on Samar, Dinagat, Siargao and Mindanao. Its small population is undergoing a rapid decline and severe fragmentation as a result of extensive lowland deforestation. It is therefore classified as Vulnerable

The Negros Scops-owl (Otus megalotis nigrorum) is generally considered a subspecies of the Philippine Scops-owl Otus megalotis but might in fact be a full species, Otus nigrorum. It is a small owl, with a length of around 20 cm., and has orange-red eyes and a rufous fascial disk. It is known only from lowland forests on Negros and Panay. Since its habitat has almost entirely disappeared, it is one of the most threatened of all Philippine owls and therefore classified as Critically Endangered.

The West Visayan Hawk-owl (Ninox philippensis centralis) is a subspecies of the Philippine Hawk-owl Ninox philippensis. It is a small owl, measuring around 20 cm. in length, with an earless, rounded head and bright yellow eyes. It is known from Panay, Negros, Bohol and Siquijor. Although it shows a large tolerance to degraded forest areas, its population is now small and further declining as a result of extensive deforestation throughout its range. It is therefore classified as Vulnerable.
