The great horned owl gets its name from the "horns" on the top of its head. These are not really horns and they are not ears either, as many people assume that they are. If you look closely at the picture above you can see that they are just feathers. What is their purpose? Great horns use them to communicate mood. It is also surmised that they help to break up the owl silhouette thus helping with their camouflage.
