why do birds have eyes on either side of their head
Bird vision Most birds cannot move their eyes, although there are exceptions, such as the great cormorant.[3] Birds with eyes on the sides of their heads have a wide visual field, useful for detecting predators, while those with eyes on the front of their heads, such as owls, have binocular vision and can estimate distances when hunting.[4] The American woodcock probably has the largest visual field of any bird, 360° in the horizontal plane, and 180° in the vertical plane.[5]
Eye of Horus Horus was the ancient Egyptian sky god who was usually depicted as a falcon, most likely a lanner or peregrine falcon.[9] His right eye was associated with the sun god, Ra. The eye symbol represents the marking around the eye of the falcon, including the "teardrop" marking sometimes found below the eye. The mirror image, or left eye, sometimes represented the moon and the god Djehuti (Thoth).[10]
