The facial disc is a concave array of feathers that is on the face of certain birds, most especially owls, which surround the eyes. The concavity of the face disc creates a circular paraboloid which absorbs sounds and directly directs the waves to the owl’s ears. The feathers that make up the disc can be adjusted through the bird’s eyes to adjust the length of this sound collector, which allows the bird to focus on various distances, and also allowing it to find prey using only sound under grass, snow, or plants.<\/p>\n\n\n\n
Other species of birds like harriers have facial discs that are less prominent. In harriers the term”face ruff” is used to describe the neck feathers which can be raised to respond to sound, increasing the size of the facial disc as well as increasing hearing.<\/p>\n\n\n\n
The barn owl is the bird with the most prominent disc on its face, which measures about 110 millimeters (Simmons) The great grey owl boasts the biggest disc in the world.<\/p>\n\n\n\n
