swimming funny ducks

Ducks are mostly aquatic birds, mostly smaller than the swans and geese, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots
Most duck species are monogamous for a breeding season but they do not often mate for life. Instead, they will seek out new mates each year, choosing the healthiest, strongest, best mate who can help them pass on their genes to a new duckling generation.
