Owls have little room in their eyes,due to the fact they have so many rods, to store muscle. This means they aren't able to rotate their eyes, but to compensate for this they are able to rotate their heads almost all the way around their necks.
Owl Ears Feathers around the ears gather sound waves then direct them towards the eardrum. Owl's right and left hears are on slightly different levels of the head meaning they can catch sounds at different times.
