EYE SIGHT FOR HUNTING Of all an Owl's features, perhaps the most striking is its eyes. Large and forward facing, they may account for one to five percent of the Owl's body weight, depending on species. The forward facing aspect of the eyes that give an Owl its "wise" appearance, also give it a wide range of "binocular" vision (seeing an object with both eyes at the same me).

The field of view for an owl is about 110 degrees, with about 70 degrees being binocular vision.

ANATOMY OF OWLSAppearance: A large, round head and huge, forward-facing eyes are features that make an Owl instantly recognisable. They also have a sharp, downward-facing beak (or bill), and soft, cryptically coloured plumage.(fig.1) Males and Females are generally similar in appearance, although the female is often up to 25% larger. After Eating, Owls regurgitate pellets, which contain the indigestible bones, fur and feathers of their victims. These pellets can be collected by researchers to study Owls’ eating habits.
EYE SIGHT FOR HUNTINGOf all an Owl's features, perhaps the most striking is its eyes. Large and forward facing, they may account for one to five percent of the Owl's body weight, depending on species. The forward facing aspect of the eyes that give an Owl its "wise" appearance, also give it a wide range of "binocular" vision (seeing an object with both eyes at the same time).

They have a normal upper and lower eyelid, the upper closing when the owl blinks, and the lower closing up when the Owl is asleep. (fig. 2) The third eyelid is called a nictitating membrane, and is a thin layer of tissue that closes diagonally across the eye, from the inside to the outside. This cleans and protects the surface of the eye.(fig.3)
