But then again, are ducks afraid of getting wet in the rain? After checking online, I learned that ducks are not afraid of getting wet from the rain. Why? There is a large fat gland at the tail of a duck, called tail fat gland . Its chest can secrete a "powder"-shaped keratinous flake containing fat. Usually, ducks will peck on them and apply the fat secreted by the tail fat glands and the "powder"-shaped keratinous slices secreted by the chest onto their feathers. When it rains, the rain will not be wet into the feathers. At the same time, this also plays a role when the ducks swim in, and the water cannot be wet into the feathers.
So now that you know that ducks have such magical waterproofing skills, will you still worry about them?
Farm, plant, insects, etc. in nature have evolved their respective environmental adaptation functions under the influence of the environment. For example, bat can fly freely in the dark, and it has powerful listening functions.
The world is full of strange things, there are always so many unknown things.
Do you have any opinions on this?
