How Birds Fly In A Misty Sky
THE HORIZON gave a slight hint there was something beyond the fog. As I walked through the wintery mist recently, I noticed a bird coming in for a landing and wondered how it managed to navigate within such a thick cloud.
I learned that waterfowl see two to three times better than most humans (and probably five times better than I can) due to highly developed retinas and amazing muscles that control the curvature of their corneas and lenses.
These lucky ducks (please forgive the irresistible pun) can also soar above low-lying coastal fog to avoid the murky shroud entirely until landing.
