Ducks' favorite activity

Hello photography lovers..
Ducks really like playing in water, do you know why? It turns out that with their spoon-shaped beaks, ducks search for food in the water . Ducks will eat algae, small fish and crustaceans which are abundant in the water. So why is playing with water their favorite activity? It turns out it's like I mentioned earlier.If the water is rather deep, the duck will not drown, because before playing in the water, the duck smears all its feathers with the oil found on its tail. Yes, there is an oil film on its tail, so when it is in water the duck can float and won't worry about drowning.
