Owl species including the Barred Owl do not have eyes in the back of their head so to see what’s going on around them they have to turn their head over 270 degrees in each direction and by doing this natural trick they can turn all the way around! When owls like the Barred Owl look to the left, they can turn their head all the way to the right and when they look to the right, they can rotate all the way to the left but how do they do this without damaging their neck and head?

An owl’s neck bones or vertebrae contains holes that are much larger than they are in other birds and us humans. In humans, the holes are about the size of an artery and in owls they are ten times the size versus humans. This causes the holes to hold air sacks which helps to cushion the owl’s neck when it turns its head, and this prevents damage to their neck. If us humans did the same thing, we would more than likely have a stroke.
So why do owls need this incredible feature? Owls have spherical shaped eyes, and their eyes are elongated tubes, and their eyes are attached in their eye sockets by bone. The tubular shape of the owl’s eyes helps the owl to have amazing binocular vision which helps in spotting prey. However, owls cannot turn or roll its eyes and instead can only look straight forward but by them being able to turn their head around allows them to get a good look around their area.
While human arteries tend to constrict when we turn our heads very far around and with owls the arteries continued to expand which allows the blood to continue to flow and eventually pool into tiny reservoirs and these reservoirs helped minimize the restriction of blood flow and to maintain eye and brain function while the owl is turning its head.
With all this being said the owls are truly an incredible masterpiece of nature!
