Philippine scops owl
The Philippine scops owl (Otus megalotis) is a common owl species endemic to the Philippines, known for its large, upright ear tufts. It is a relatively small, sedentary owl found in forest understories, with three subspecies distributed across different Philippine islands. These nocturnal carnivores primarily feed on insects and small mammals and are considered Least Concern by the IUCN, though vulnerable to habitat loss.

About Philippine scops owl
The Philippine scops owl, scientifically known as Otus megalotis, is a common owl species native and endemic to the Philippines. This owl belongs to the family Strigidae, commonly referred to as typical owls, and is distinguished by its prominent, large upright ear tufts, which give it its specific name, 'megalotis,' meaning 'large ears' in Ancient Greek. It is a relatively small, sedentary bird that typically inhabits the forest understory.
Description and Subspecies
Adult Philippine scops owls measure between 23 to 28 cm in length, with body mass ranging from 125 to 310 g, and females are often noticeably larger than males. Their plumage is generally dark brown with dark streaks, including on their ear tufts. They have large, dark eyes with a red or orange edge, a whitish forehead, and a dark line around their facial disc. There are three recognized subspecies, each displaying variations in morphology: O. m. nigrorum is the smallest with a reddish-brown color, O. m. everetti is medium-sized and greyish-brown, and O. m. megalotis is the largest, also grey-brown, and exhibits a scapular line and feathers on its upper feet. These subspecies are distributed across different islands of the Philippine Archipelago.
Habitat and Distribution
Philippine scops owls are found in various forest types, including rainforests, mature secondary woodlands, and forest edges. They are predominantly observed in the understory and rarely ascend above 1,000 meters in altitude. The species is endemic to the Philippines, with its three subspecies occupying distinct geographical areas: O. m. megalotis is found in the northern islands like Luzon, Marinduque, and Catanduanes; O. m. everetti inhabits the eastern and southern islands such as Samar, Biliran, Leyte, Mindanao, and Basilan; and O. m. nigrorum is endemic to Negros Island. These owls are not known to migrate, resulting in a limited distribution for each subspecies.
Behavior and Diet
These owls are nocturnal carnivores that actively vocalize at night. Their song is characterized by a series of 'oik' notes followed by a lower 'ook,' while their call is a rapid sequence of escalating notes. They are described as ferocious feeders, preying on insects and small mammals. Hunting typically occurs at night from perches in trees. Their diet also includes spiders, and they are known for their method of crushing prey's head before swallowing it whole. They are monogamous and provide parental care, with nests constructed in tree cavities or among tree roots.
Conservation
Classified as Least Concern by the International Union for Conservation of Nature (IUCN), the Philippine scops owl faces threats primarily from habitat destruction due to deforestation, logging, agricultural conversion, and mining. Despite being found in several protected areas, these activities continue to impact their populations. The species is also occasionally caught for the pet trade. The overall population is believed to be declining, highlighting the vulnerability of this endemic owl to ongoing environmental changes.
