Ducklings can't swim

Looking at the two little ducks, holding them in their hands, warm, light, really makes people love it. Yellow-yellow feathers, tender little wings, long small flat mouth, red duck plaque, very cute. The most interesting thing is that they have a black hair on their head and tail. Their screams are not called "squeaky" like a big duck, but they are called "squeaky" like a chicken. I used a box and a newspaper to give them a comfortable nest.

I have a whimsy, big ducks will swim, and will the newborn ducks swim? Just want to test the test, I can immediately be opposed by my father, afraid that the duck is frozen, not let me try. But I thought, in the story of "The Ugly Duckling", the ducklings will swim when they are out of the shell. The two ducklings will definitely swim, but the helpless father has to agree.

I took a basin of water and put it on the stool. I carefully brought two ducks and put one in the basin. I was worried that it would be drowned. Who knows that the duckling that was born a few days is as fun as I was when I was a kid. Water, first stretched out, looked around, "唧唧" called two, then free to play in the water. It seems that the worry is superfluous, and I quickly put another duck into the water. Good things are coming, two ducks are playing, you are driving me, I am chasing you, you are jealous of me, I am jealous of you. Sliding water with your feet, stirring up the blossoming water, playing while playing, sometimes putting your head into the water, you may also want to find some small fish and shrimp to eat, watching them play, I am also very happy It is.

I grabbed a small duck and prepared to receive the "Bing". The duckling was still warm and there was no water on the feathers. It’s just that there are a lot of crystal clear water drops on the back, just like the water drops on the lotus leaf, which makes me curious. Why is this duck feather not wet? I put the duck that I just brought back into the water and continued to observe the duck swimming.

I stared at the ducklings intently. Their feathers were neat and tidy. They were not as messy as the chickens. They also found that the ducks had several "small movements" when they swam, often twisting their heads and licking their mouths from the back to the feathers. Next, sometimes the head is also on the feathers, and nothing else is seen. I remember seeing the detailed introduction of the ducks in the book "Let the children fall in love with science". I have to ponder over it!

It turns out that the feathers of the ducks are curved, and there is a uniform gap between the feathers and the feathers. There is of course air and air. It is quite a life-saving circle in our water, and of course it can float. The air in the feathers will not run away and the feathers will not touch the water, because the feathers on the feathers are greased, the feathers with the oil are naturally not wet, the fat of the ducks is derived from the sebaceous glands in the tail, and the ducks turn their heads to comb the feathers with the mouth. The back is used to take grease, and then the mouth is applied to the feathers. The feathers with grease also serve to seal the air. Everyone knows the fat of the head. When it comes into contact with the body, it is fat on the head.

This is my observation and discovery, I like the duckling friends, but also buy two!
