Skeletal-Muscular System

Posted in Organ Systems, Skeletal-Muscular System at 10:24 pm by philippineeagleowl

The Philippine Eagle Owl has an endoskeleton. Its skeleton is specially designed for walking and flight that why it’s light but strong. Like all other owls, the Philippine Eagle Owl’s skeleton contributes to only 7-9% of their body weight. Some of the Owl’s larger bones are hollow, which helps reduce the overall weight.

The Philippine Eagle Owl’s neck has a total of 14 vertebrae. This allocates the owl to turn its head through a range of 270 degrees. The Philippine Eagle Owl also has outsized and powerful flight muscles. This is supported by the Sternum. The Sternum also shields and protects other internal organs like the heart and lungs. Being one of the largest owls, the Philippine Eagle Owl’s wing bones are very long, with broad associated wing surface, creating a low wing loading. Even when carrying prey, this characteristic enables the owls for trouble-free take-offs and unforced flights. Its foot bones are fairly short and assist in the competent killing and carrying of prey.
