I grew up in the countryside. When I was a child, I often saw scarecrows scaring birds in the fields. Children's friends sometimes criticize the scarecrow and argue about whose works are interesting and whose scarecrow is effective. Scarecrow is a memorable thing in childhood memory.

Now back home, I will never see the scarecrow again. Not only my hometown, I have traveled all over the country and have hardly seen it.

Many distinctive items in the countryside are slowly disappearing, and I'm afraid this scarecrow will also quit the historical stage.

First of all, whether the scarecrow is useful or not.

According to my observation when I was a child, the scarecrow is actually useless, or has little effect. Only when the wind blows, the scarecrow's clothes fly, which can also play a deterrent role. On a sunny day, it's a decoration. Clever birds like crows and magpies often use scarecrows as their resting places. Just look at the bird droppings on the scarecrow. These guys seem to be mocking the absurdity of human beings.

There is a joke, which is very interesting. Rural girls are not pretty. How bad is it? Birds always steal her crops, and scarecrows are useless. Her mother asked her daughter to go out of town to watch it. As a result, she only went for one day, and no birds visited this field again.

In short, the scarecrow's effect of driving away birds is not obvious. In the past, farmers were not well educated and worshipped the traditions left by their ancestors, so some customs were handed down. Nowadays, young people, who have mastered knowledge, probably won't use these ineffective means any more, so scarecrows are not favored.

At present, there are many ways to drive away birds: covering crops with nylon nets (suitable for small intensive farmland); Ultrasonic drive birds, different birds have different tolerance to different frequencies of ultrasonic waves, so use its specific frequency to drive birds; Digital voice bird repeller, similar to ultrasonic bird repeller, but its sound imitates the sound of natural enemies and similar warnings to scare away birds; Laser bird repeller, the laser beam emitted by the green laser tube with wavelength of 532nm can effectively repel birds at night; Falcon bird catching method, breeding and training falcons, can drive and kill birds very effectively.

With the development of agricultural modernization, the change of ecological environment, the renewal of rural farming methods and the scarecrow's function of repelling birds, people no longer value it, but it has not disappeared. In recent years, people have gradually turned the Scarecrow into an expression of agricultural art, and many leisure agricultural parks and beautiful countryside areas have developed the Scarecrow into a leisure and sightseeing product with ornamental and color sense. The scarecrow was reborn from this, which is gratifying.
