Explanation:
Whether they have eyes at the front or on the sides of their heads, all birds can still see straight ahead. But that doesn’t mean all birds see things in the same way. In fact, where a bird’s eyes are on its head can tell us a lot about how it sees the world.

Having two eyes means animals can see a three dimensional image of what’s around them. So they can perceive the height, width and depth of an object, as well as how far away it is.
Where a bird’s eyes are on its head affects its field of vision – that’s how much it can see in front and to the side at any one time. Think about how far you can see to either side without turning your head: these are the limits of your own field of vision.
Because owls have eyes at the front of their heads, they have a smaller field of vision – around 150 degrees for a barn owl (though they can turn their heads very far to look around).
Parrots, pigeons and other birds with eyes on the sides of their heads have a much bigger field of vision, of about 300 degrees. Amazingly, this means that they can see in front and a long way to the side, at the same time.
