What's the use of installing windmills on telephone poles?

According to the query of Baidu Library, the windmill on the fairy waste is used to drive away birds. In order to prevent the construction of desert islands on electric waste, most small windmills are also equipped with small mirrors. When small windmills rotate, small mirrors on their blades can reflect sunlight in all directions. For birds, a small windmill is like a rotating warning light, which can send out a strong flashing signal.

Bird repellent is also called bird repellent, bird prevention, bird collision prevention, etc. Broadly speaking, farms, orchards, wind power plants, military and civilian airports and all other means to prevent harmful birds from invading their own territory, thus endangering the safety of their labor achievements or equipment, are called bird repellent.
