Owl, Toronto Zoo, Ontario, Canada 05

Description : All owls have specially designed eyes, ears, and wings to enable them to capture their prey. Their eyes are large and on the front of their faces, giving them binocular vision and fine depth perception. They have a large concentration of rods on their retinas, but they see little color. Their eyes are ten times as light-sensitive as human eyes, but they are short-sighted so they hunt near the ground. Their eyes are so large that there is little room in their skulls for eye muscles. Thus an owl turns its head, sometimes as much as 270 degrees, rather than its eyes, to follow a moving object.

Owl ears are located on the sides of the facial disks, those round feather arrangements, and give owls the most highly developed sense of hearing of all birds. The facial feathers help to amplify and channel sounds to their ears. Generally one ear is larger than the other and slightly above or below, so the owl can pinpoint the location of a sound. It can hear a mouse or a cricket in the grass below!

The Zoo is divided into six zoogeographic regions: Indo-Malaya, Africa, the Americas, Australasia, Eurasia and the Canadian Domain. Animals are displayed indoors in tropical pavilions and outdoors in naturalistic environments, with viewing at many levels.
