How to expel magpies?

First of all, you can insert a stick into Gua Tian and tie several CD or VCD waste discs to it from different directions. Birds are disgusted with the reflection of discs, which can effectively drive away birds.

The second is to tie some small glass bottles to a stick and open the bottle mouth. When the wind blows through the bottle mouth, it can emit infrasound waves that people's ears can't hear, and it will also drive away birds.

Third, when the scarecrow can't scare the birds, tie a bell to the scarecrow and drive the birds away with sound.

Life habits of magpies:

Magpies often move in small groups of 3-5 in the breeding season, and often integrate dozens of large groups in autumn and winter. During the day, I often go to open areas such as farmland for food, and fly to nearby trees to rest at night. Sometimes I see crows and western Western jackdaw mixed activities. Be alert, there is always a bird to guard when foraging. Even if they feed in pairs, they usually take turns waiting for food.

The diet is diverse, and the food composition changes with the season and environment. Animals such as insects are the main food in summer, and fruits and seeds of plants are the main food in other seasons. Common food types are insects and larvae such as LEPIDOPTERA, COLEOPTERA, ORTHOPTERA and HYMENOPTERA. Such as grasshoppers, grasshoppers, beetles, owls, ground tigers, caterpillars, bedbugs, ants, flies and snakes.
