Being in the woods or in the park, you've probably heard a very characteristic knock on wood more than once. That was what the woodpecker was making noise. This so-known noise comes from the fact that the woodpecker hits the tree with its beak.
What do woodpeckers look like? You may even have seen him. Woodpeckers are very colorful, the most common ones are black and white and red, but I do not know if you know that there are also green-red and black-red woodpeckers in our country as well as completely gray ones?
Remind yourself, have you ever hit your head or knee? And how did you feel? It certainly hurt a bit, right? Fortunately, our mothers and sometimes even tats, have magical healing power, all they need to do is kiss where it hurts or strike this place and it stops hurting right away. But what do woodpots have to do? After all, woodpeckers can not get a kiss or be stroked. Does it sometimes hurt their head to hit the trees?
Well, it turned out that the woodpecker is a very amazing bird whose body is built so that it does not hurt at all when hitting a tree. The woodpecker can hit its beak up to 20 times a minute, several thousand times a day. And it strikes with the same speed that you're riding your bike as fast as you can and it's downhill.
Why do woodpeckers knock trees? Woodpeckers are often called tree doctors. And not without reason, woodpeckers love to eat different bugs, caterpillars, ants and in winter even seeds. A lot of bugs and caterpillars are found under the bark of trees. To get to the bark, they tap her with their beaks, when they can pull away her piece, they use their language. Thanks to the knocking, woodpeckers also talk to each other.
The woodpecker's tongue is very unusual and very long. It has a length of up to 15 cm, which is more or less the length of a chocolate bar. This language is very sticky and it has hooks. As a result, it is great for pulling larvae out of the bark and corridors. But where is such a long tongue in such a small woodpecker? Does he hang freely from his beak and twist in twigs? It will seem very strange to you, but the woodpecker's tongue is wrapped around his skull.
But why does the woodpecker not hurt the head? This is due to the fact that the entire impact force is absorbed by the body of the woodpecker and only a small amount of it reaches the head as heat. To cool off, the woodpecker must pause in a tree. Hence the characteristic breaks in knocking.
If you want to see how this impact absorption works, you can do a simple experiment. take a sponge from the bathroom - just have to be at least three fingers thick, and put it on your hand, then take an apple or other fruit and drop it on a sponge on your hands from different heights, then remove the sponge and repeat the fruit drop. Is the difference right?
