Locomotion
The Spectacled Owl's locomotion comes from flying and for walking and because they have these two techniques to get around, their skeleton is built for efficiency in both. The actual skeleton of the bird makes up 7 to 9 percent of its body weight and is built to be strong yet light.
Bones that are seperated in mammals are actually fused together in owls to support their body weight when they are standing on the ground. However, some of the larger bones are hollow in order to reduce body weight for flying.
The owls breast bone, or sternum, is large and flat to support the owl's flight muscles. The wing bones in owls are fairly long and the wing surface is broad which help with easy takeoffs and more efficient flight. Their wingspan is 76 to 91cm.
