Bubo philippensis

The Philippine eagle-owl (Bubo philippensis ) is a vulnerable species of owl belonging to the family Strigidae. It is endemic to the Philippines, where it is found in lowland forests on the islands of Catanduanes, Samar, Bohol, Mindanao, Luzon, Leyte and possibly Sibuyan. The Philippine eagle-owl feeds on rodents and amphibians. Due to their reliance on living in large lowland forests, forest conservation is important in order to maintain populations of the Philippine eagle-owl, which is becoming increasingly vulnerable to going extinct. The Philippine eagle-owl was previously listed as endangered, but due to destruction of lowland habitat and possible hunting, the eagle-owl has since been adjusted to the vulnerability of extinction.

Appearance

The Philippine eagle-owl has a total wingspan of about 48 inches, and with a total length of 40–50 cm (15.5–19.5 in) and a wing-length of about 35 cm (14 in), (where typically a female would size larger than a male) it is the largest owl in the Philippines, but among the smallest members of the genus Bubo. It is overall rufous with a lighter belly and yellow eyes. It has a warm brown coloring with many markings on its back, with a bird call pitch of a long whistle that rises shortly and falls at the end. It is also described as being incredibly bulky and having tufted ears, closely resembling the Buffy fish-owl, Ketupa Ketupu.

Mating Habits

After hatching, Philippine eagle-owl chicks need to be intensely cared for by their parents. These new chicks are unable to thermoregulate by themselves, so they need the body heat from their mother or father to keep them warm. These chicks are also unable to feed themselves due to their lack of ability to fly. The father bird will go out to catch the food while the mother will tear it up into smaller pieces for the chick to eat.

Population

Population threats

The Philippine eagle-owl has faced threats from several factors within its habitat. Some of those factors include deforestation for agricultural use, commercial logging, and natural causes that destroy the bird's habitat such as catanduanes and typhoons. Another factor that was contributing to the near extinction of these birds was illegal hunting and lack of enforcing the laws. In the Philippines, some law enforcement agencies have poor management and internal corruption. This corruption contributes to the long surviving issue of poaching and illegal trading of animals.  Interbreeding has also threatened the eagle-owl since it produces offspring that are infertile and unable to produce.
