Caught mid-blink! How cool is that?! Did you know herons have a special see-through eyelid called a nictitating membrane? It protects their eyes while keeping their vision sharp! Nature’s coolest built-in goggles! #birds #photography #heron #nature #photo #eastcoastkin

Pretty much all birds have them. If you photograph diving ducks, you can easily capture that by doing serial shots of them diving. They always put their googles on 😉
