The sound of geese goes north to Yan Nanfei , why do geese go north? Why did Yan fly south? Where a

Because geese and swallows have such a habit, they will leave the cold place in winter, and when it is warm, they will return to the north.

Because of the climate, when it is winter in the north, it is very cold, the swallows will fly to the south, and when the north is warm, the swallows will come back.

These swallows will fly to some very warm places, and generally fly south to spend the winter.

I think they will fly to Sichuan, Hunan, Chengdu, Xianyang, Changsha and some other places.

Swallows from East Asia fly to Southeast Asia and Australia in search of a suitable living environment.

<> swallows are migratory birds that migrate with changing climates. In winter, the temperature in the north is low, which is not suitable for them to survive, so they have to migrate south. When the spring flowers bloom, they will return from the south to the north to have children and live and work in peace and contentment.

Swallows feed on insects and are accustomed to preying on flying insects in the air, and there are no flying insects for swallows to hunt during the northern winter. The lack of food has forced the swallows to make a great north-south migration every year.

Swallows are beneficial birds for humans, and generally return from the island from the island to breed in April and July, where they nest under the eaves of farms. It mainly feeds on mosquitoes, flies and other insects, and can prey on more than 500,000 pests in a summer, protecting crops, so humans should protect this beneficial bird.

Swallows spend a lot of time catching pests in the air and are one of the most flexible passerine species, mainly feeding on mosquitoes, flies and other insects, and are well-known beneficial birds. Nest in tree holes or crevices, or drill holes in sandy banks, or stick mud on walls or protrusions in corridors, roofs, eaves, etc. in urban and rural areas. 3 7 eggs per lay.

Swallows are not opportunistic foragers, flying around aimlessly and eating plankton randomly into the air with their mouths open. Instead, they take the initiative to hunt specific prey. The diet of migratory bird species in their wintering grounds is usually different from that of their breeding grounds.

For example, when house swallows overwinter in Africa, the proportion of ants in their food increases. In addition, the degree of foraging preferred by a species can vary between wintering and breeding grounds. The above-mentioned infiltration is thought to be the result of the competition between these migratory birds and the resident bird species in the wintering grounds. Cong Qi.

1. The swallow is a migratory bird. In the autumn before winter comes, they will fly from the north to the far south, where they will enjoy the warm sunshine and humid weather, and then return from the south to their hometown to have children and live and work in peace and contentment when the spring flowers are in full bloom.

2. Swallows feed on insects, and are accustomed to preying on flying insects in the air, but they are not good at searching for insect food in tree crevices and ground gaps, and there are no flying insects for swallows to hunt in the northern winter.

3。The lack of food has forced the swallows to make a great north-south migration from autumn to spring every year in order to get a wider living space.

1. Because geese are migratory birds, they have to migrate every year, they were born in northern Siberia, and the sunshine time in the northern summer is relatively long, and compared with the winter, the food is more abundant, and there is no need to worry about the food problem of themselves and their cubs, which is very suitable for feeding offspring, so they will return to their birthplace to breed offspring.

2. Then after winter, the corresponding weather becomes colder, the sunshine is not so long, the plant seeds and leaves are gone, the corresponding insect eggs become fewer, and the geese have no food to eat, so they will fly to the warm south in groups.
