If we try to imagine and draw the electricity poles on the street, we cannot do without adding the birds on the wire, which are indispensable for electrical wires. Because we see them so much every day and everywhere that it is a habit for us now. As it is customary, we dive into their superficial voyages without looking at these birds in detail.
Birds perched on electrical wires or tree branches a common behavior there is. Except for the exceptions (we will mention), all of these birds in the same direction Did you ever notice what they’re looking at?
In this article, almost everyone sees but few people notice We wanted to address this situation.
Birds usually have a heavy front side and a light tail side where their wings are extended.
Therefore, when they fly into the wind, they are less wind resistance they live. The same is true when they are put on electrical wires. All to reduce wind resistance wherever the wind blows they turn their bodies there. When they turn their heavy front side to the wind direction, they face the wind. more strong they can stop.
Also, feathers facing backwards are suitable for this direction of airflow.
When the wind blows against them does not fluff and as it flows over your wings balance is not disturbed. If they were looking in the opposite direction; The incoming wind would make their feathers fluff, upsetting the balance of this light part and making it difficult for them to stand firmly on the ground. That’s why birds; even if the wind changes direction aerodynamic structures because they will always be looking in the same direction.
The second advantage of looking towards the wind is that it is easier and more controlled to fly from where they land in case of danger.
At first glance, it may not have made sense for birds to fly against the wind when they have the wind behind them. But remember that airplanes And they take the wind against them and get up. Because the headwind blows the plane through the wings. increases the speed of the airflow and makes the plane take off faster.
Or, to give a simpler example, consider kites. Even if you run for hours with the wind behind you, it will not take off. for ventilation you have to run against the wind.
But what happens when the weather is windless?

As you can imagine, since the direction the birds are facing depends on the wind, and when it is not windy, the birds They look in randomly chosen directions. Just like in the photo above.
