When we say take off, we all think of birds. The birds that soar freely in the sky have all kinds of colorful feathers on their bodies. So is it possible to have a feather and be able to soar freely like a bird? But the reality is that we, as human beings, don't fly with a feather. It turns out that the feathers on birds are more than just flying. So what else does bird feathers do?
In fact, feathers can also be equal to umbrellas. The tricolor heron living in the swamp park is standing in the water, spreading its wings and carefully searching for food in the water. On a clear day, the sun shines on the water and sparkles everywhere. In order to be able to see the fish and frogs in the water, the tricolor heron uses the feathers on its wings to block the sunlight, like a parasol, so that the tricolor heron can clearly see the prey being preyed.
In addition, feathers can also be used as kettles. There is a magical bird in the world. They drink water in a very peculiar way, through feathers. On the Gobi Desert in Mongolia, a hairy-legged sand chicken father is shaking off its feathers, squatting in the water resistance and not moving, letting the feathers suck up the water, before flying back to the nest to feed the baby sand chicken. In the harsh environment of the Gobi Desert, the water in the feathers can make the father of the sand chicken cool down quickly, and the water in the feathers can also be used to let the sand chicken baby drink precious water.
Finally, feathers can actually play a whistle function. Such a bird lives in the Lepi Bird Sanctuary in Ecuador, South America. Its feathers make a loud whistle-like sound. This bird is called the plum-winged coltry, and this bird attracts the opposite sex by vibrating its wings and making a noise. The above is the role of feathers, the role of feathers is not only umbrellas, kettles and whistles, feathers have many other functions, in addition to these haha know what? Welcome to add.
