The mysterious bird belongs to the mysterious bird finger

Specific instructions:

There are three times in the Millennium, once when the geese come, once when the mysterious birds return, and the third time when the birds are ashamed. At this time, migratory birds such as Hongyan and Swallow began to fly south to avoid the cold, and hundreds of birds began to reserve dried fruit food for the winter. Among them, the "dark bird" refers to the swallow. Swallows will fly to the south for the winter to find a more comfortable and safer place.

The Millennium solar terms symbolize the end of summer and the beginning of autumn. The weather is getting colder and colder, and swallows need to fly to a warmer climate for the winter. So the phenomenon of blackbirds returning is that swallows fly to the south for the winter.

Swallow introduction:

Eating habits of swallows:

Swallows are people? Beneficial birds mainly feed on mosquitoes, flies and other insects. They can eat 250,000 pests in a few months, so we should protect them.

Swallows always travel long distances before winter comes every year-they fly from the north to the far south in droves, where they can enjoy warm sunshine and humid weather, and leave the frost and cold wind in winter to tits, grouse and Thunderbirds who never fly to the south for winter.

Swallow's habitat:

Swallows are most willing to approach humans, and humans also love this beneficial bird. "From the foreign curtilage island in spring, willow bit mud cut rain fly. Don't get close to the rich and the people, but whisper and hug "(Heshui Zuo).

Swallows usually return from the island to the farm near the farmland (insects) to breed from April to July. Domestic swallows nest under the eaves of farmhouses. Most of these nests are made of saliva-bonded soil and grass stalks, covered with soft weeds, feathers, rags and so on. And some Artemisia annua leaves.
