@legablegrace: Kingfishers: fishing pros with built-in high-tech gear. They lock onto the target with a built-in gimbal. Before diving, they adjust their eye lens to instantly correct for the difference between air and water refraction. Their retina has TWO foveae – one for seeing in air, the other for underwater! Once they hit the water, they switch visual modes and close a translucent third eyelid (like a built-in goggle) that shields their eyes without blurring their vision. Their feathers are coated with oil from a special gland – a natural raincoat that makes water bead right off. Trapped air under their feathers even helps them pop back up.#smartbird #kingfisher #wildlife #AnimalFacts #Legable
