The eyes of ducks and geese are indeed beautiful and fascinating to observe. They are typically located on the sides of their head, giving them a wide field of vision that allows them to detect predators or prey from different angles.
Ducks and geese have large, round eyes with dark pupils and bright irises. Some species of ducks have strikingly colored irises, such as the Wood Duck which has bright red eyes, or the Mallard which has a bright yellow-green eye ring.
Another interesting feature of duck and goose eyes is their ability to adjust to underwater vision. They have a clear third eyelid, called the nictitating membrane, that helps protect their eyes while diving and also provides a protective layer for their cornea.
In summary, the eyes of ducks and geese are not only beautiful but also highly adapted to their unique environments and behaviors.
